UK

A rule-author and one of the three depositary governments of the NPT, alongside the US and Russia. As an original nuclear-weapon state it helped write the who-may-hold rule and remains a government with which the regime's instruments are deposited — a hand on the order itself, not merely a holder of weapons.

How the field was judged across the 12NPT rule-authorship: US/UK/Russia are the 3 depositary governments AND original NWS → top tier (US 95 as primary depositary/architect, UK/Russia 90); France/China are NWS rule-authors but acceded late (1992) → 70; non-NWS parties are rule-takers bound by the regime → 20-25 (Germany/Japan/Italy/Canada 25; Brazil late accession 1998 and South Africa uniquely disarmed before acceding → 20); India is an NPT non-party that rejected the regime entirely → rejecter/outsider, not a rule-taker: outside the framework, neither authoring nor bound by it → 10.

Among the structurally-advantaged with Art VI-secured Board influence as one of the most atomic-advanced states, it shares control of the IAEA inspection lever rather than submitting to it. A significant civil and military nuclear power on the safeguards machinery, level with France.

How the field was judged across the 12Control of the IAEA safeguards/inspection lever via the Art VI designation rule (the 10 'most advanced in atomic-energy technology' get permanent Board influence). The 8 structurally-advantaged of our 12 are US/Russia/China/France/UK/Germany/Japan/Canada → US 90 (regime leader/largest civil+military nuclear base), Russia/China 70, France/UK 65, Germany/Japan 50, Canada 45 (major uranium/civil-nuclear but smaller weight); Italy/India sit only via rotating elected seats → 20; Brazil/South Africa peripheral inspection subjects → 15.

An NWS voice in multilateral arms-control settings but, like France, outside the bilateral regime whose treaty has lapsed; it cannot set or block the successor's terms. Marginal agenda power on the strategic-arms question — present in the conversation, not steering it.

How the field was judged across the 12New START EXPIRED 2026-02-05 (before the cutoff) → strategic-arms regime is a VOID at the edition date, so agenda power is suppressed across the board (no holder scores high — there is no live regime to set terms of). Residual agenda power = who shapes the contested successor: US sets the terms (demands a China-inclusive treaty) → 60; China holds blocking power by refusing to join → 50; Russia was co-principal but offered voluntary adherence and was rebuffed → 45; France/UK are NWS voices in multilateral fora but outside the bilateral regime → 20; non-NWS states are NPT parties but non-participants in the bilateral strategic-arms regime, so they shape no terms → 5-10.

A genuine provider, but a junior one: the UK is a NATO Article 5 co-guarantor and, like France, fields an independent nuclear deterrent underwriting that pledge, placing it among the only three providers within the set. Its standalone umbrella is modest beside the US, so it sits as a secondary guarantor rather than the hub.

How the field was judged across the 12Who FORMALLY protects others. US is the principal provider (NATO Art 5 anchor + Japan/Korea/Philippines bilateral + hemispheric Rio umbrella) → 95; France/UK are NATO Art-5 co-guarantors AND independent nuclear-umbrella providers but minor own-deterrents relative to the US → 35; Russia is a rival provider via CSTO (beneficiaries outside our 12) → 20; Germany/Italy/Canada/Japan are recipients/consumers of the umbrella, not providers → 5; China/India/Brazil/South Africa extend no formal extended-deterrence guarantee → 5.

The closest peer-ally and a modest terms-sharer: the UK pairs deep alignment with the US protector with its own limited external posture and basing reach, so it extracts something rather than nothing. It is far below the US as a setter of terms, scoring as a secondary participant in the bargain.

How the field was judged across the 12Who EXTRACTS terms (basing, burden-sharing, alignment) in exchange for protection. US is the net provider of terms — converts protection into forward basing in Germany/Italy/Japan/UK + cost-sharing → 95; UK is the closest peer-ally and terms-sharer with its own modest external posture → 30; France runs an independent posture but extracts little from others → 15; Russia extracts basing terms within CSTO (outside our 12) → 15; Germany/Italy/Japan are terms-takers hosting US presence → 5; the rest extract nothing → 5.

A central junior hub: the UK is woven deeply into the US-anchored network through command integration and nuclear cooperation, making it the most connected node after the principal. It is a hub, not a spoke, but a subordinate one, so it scores as the leading junior center of the network.

How the field was judged across the 12Network centrality as provider, not summed allied force. US is the indispensable hub — SACEUR is always a US officer; anchors NATO integrated command, NORAD, and the Pacific bilateral spokes → 95; UK is a central junior hub (deep US integration, nuclear cooperation) → 35; France is semi-peripheral (left/rejoined integrated command, independent posture) → 25; Russia/China are hubs of RIVAL networks (not the Western provision network) → 25/20; Germany/Italy/Canada/Japan are spokes not hubs → 10; India/Brazil/South Africa non-aligned/peripheral → 5.

A residual presence junior to the US. Diego Garcia and a Gulf footprint give Britain standing near the chokepoints, but it operates inside the American command architecture rather than commanding any strait in its own right — a former authoring power now a contributing one.

How the field was judged across the 12Command of the straits others must transit. US is the only one of the 12 with standing naval command across multiple chokepoints (5th Fleet/Bahrain over Hormuz+Bab-el-Mandeb; 7th Fleet over the Malacca approaches) → 90; China is the sole contender, building blue-water reach but commands no strait yet → 35; UK has residual presence (Diego Garcia, Gulf), junior to US → 20; France has residual presence (Djibouti, Indo-Pacific territories) → 15; India regional Indian-Ocean presence → 10; others have no chokepoint command → 5.

A leading allied contributor to the US-led Combined Maritime Forces with its own deployable reach. Britain provides meaningful sea-lane security, but as a senior partner inside the American command structure rather than as the hub — provision exercised, command lent to the provider.

How the field was judged across the 12Who polices the sea-lanes others depend on (provision, not tonnage). US leads and commands the 47-nation Combined Maritime Forces (HQ Bahrain, US officer commands, 5 task forces over ~3.2m sq mi) → 90; China provides outside the US structure via its own independent Gulf of Aden escort task force → 30; UK/France are leading allied CMF contributors with own deployable reach → 25; India contributes and runs independent IOR patrols → 20; Japan/Italy active CMF participants → 15; Canada/Germany participate → 10; Brazil nominal participant, Russia/South Africa absent → 5.

A top-tier author of the maritime ground rules. The UK holds an IMO Council Category A seat — largest shipping interest — keeping a senior hand on the rules of passage, the institutional legacy of the naval rule-regime Strange described, even as its command at the straits has become residual.

How the field was judged across the 12IMO Council seats set the maritime ground rules, tiered by category. Category A (largest shipping interest) — China/Italy/Japan/UK/US → top rule-setting tier 80; Category B (largest seaborne trade) — Brazil/Canada/France/Germany/India → 55; Category C (geographic representation) — South Africa → 35; Russia was voted OFF the Council after 2022 (structural exclusion) → 5.

A Budapest party — adopter, not author. The UK ratified the cybercrime convention founded by the US, Canada and Japan and operates within it, but did not author the regime's rules. On Strange's structural line it takes the framework rather than designing it.

How the field was judged across the 12Who writes the rules of the digital domain (Budapest Convention/CETS-185 vs the rival UN Cybercrime Convention). US/Canada/Japan are founding authors of the dominant Budapest regime → US 90 (lead author), Canada/Japan 70; Russia is principal driver of the rival UN framework (a competing authorship venue) → 65, China co-driver → 60; France/Germany/Italy/UK are Budapest parties = rule-adopters, not authors → 35; Brazil acceded to Budapest but also works the UN process → 30; India is a Budapest non-party that leans toward the UN process without committing → 12; South Africa signed-not-ratified Budapest and merely leans to the UN framework → 8 (the floor: neither authors nor cleanly adopts, below all clean adopters).

A genuine provider, second only to the US. The UK supplies cyber-defence guidance, threat intelligence and CERT-level support through the NCSC and its place in Five-Eyes intelligence-sharing — the two channels the score_basis names. Its distinct position is the bridge role: it is the only European state inside the Five-Eyes core, so it relays Anglosphere threat intelligence into European partners that the US shares with less directly. It shelters others within its framework rather than merely defending itself — provision in Strange's sense, at meaningful scale.

How the field was judged across the 12Who supplies cyber-defence others depend on. US is the primary provider — NATO cyber-defence-pledge anchor, CISA standards exported, allied CERT support → 90; UK provides via NCSC + Five Eyes sharing → 50; France provides via ANSSI + EU framework → 40; Germany provides within EU/NATO → 35; China provides an alternative model (surveillance-stack exports) to its sphere → 35; Japan regional provider and Canada Five Eyes provider → 30; Russia provides an alternative model to its sphere → 25; Italy is a framework participant → 20; India/Brazil/South Africa are recipients/non-providers → 10.

The UK controls no physical critical-input chokepoint — it neither refines the scarce minerals nor supplies the non-substitutable materials others must buy. It sits among the lowest, a consumer of inputs whose terms are set elsewhere.

How the field was judged across the 12China high on rare-earth refining chokehold; US high on tooling/inputs upstream; Japan on materials (photoresist, silicon wafers); Russia/Brazil/SA on raw-mineral inputs but NOT refining. Leading-edge foundry/litho chokepoints sit with TW/KR/NL (outside set), depressing all 12's absolute scores here.

The UK gatekeeps no leading-edge process or tooling step at scale; its strength lies upstream in design-method rather than in controlling the physical process. The low score marks near-absence from process gatekeeping.

How the field was judged across the 12US overwhelming via EDA (>85%) + WFE leadership. Japan strong (Tokyo Electron WFE, JSR/Shin-Etsu precursor chemistry & resists). China near-zero at leading-edge process despite SMIC volume.

The UK holds a small share of denial leverage through its own export-control regime but exercises no input-denial at the scale of the US, China, or Japan. The score marks limited independent exclusion capacity.

How the field was judged across the 12US + China are the two actors who actually wield production-input denial at scale (semiconductors / rare earths respectively). Japan joined US-aligned WFE controls. EU members get a modest shared EU-regime-participant credit (D16: lever is national, not bloc — euro-style full-bloc attribution does NOT apply).

The UK retains Arm ISA design-method authorship in its R&D base — a genuine production-method that much of the industry designs to — giving it method-setting weight above its size. The score reflects real authorship of a design method, concentrated in one platform.

How the field was judged across the 12US authors the dominant production methods (EDA Big-3 >85% share + 95% lock-in, design-rule/WFE method via Synopsys/AMAT; SIA: US firms 50.4% of global design/sales). Japan co-authors process-chemistry/equipment methods (Tokyo Electron, Shin-Etsu, JSR). Germany niche method-supplier (Trumpf EUV source, Zeiss optics); UK retains Arm ISA design-method authorship in its R&D base; France (Soitec SOI), Italy (ST niche). China authors only domestically enforced GB standards with limited frontier adoption; rest negligible.

UK lead firms exercise moderate governance over suppliers, leaning on demand-side and brand position more than a deep industrial supplier-network system; they dictate terms within their own chains but govern a thinner manufacturing supplier base than the continental OEMs.

How the field was judged across the 12US dominant lead-firm governance (outward FDI + brand/platform lead firms). Japan/Germany strong (Toyota/VW supplier-network governance). China rising lead-firm power but more state-directed. Russia/Brazil/SA low — chain participants, not governors.

The UK controls almost no irreplaceable chain nodes; it cannot deny downstream access at scale and sits near the bottom on exercised chokepoint power.

How the field was judged across the 12Mirrors input-control chokepoint distribution (US tooling/design nodes; China refining/rare-earth nodes; Japan materials nodes; Russia/Brazil/SA raw-input nodes only).

The UK authors the BRCGS food-safety standard and related retail-supply codes — a genuine but sector-bounded authorship that suppliers in those chains must meet.

How the field was judged across the 12US authors the dominant private chain standards (Apple/Walmart supplier codes, UL, platform/retail rules others must meet to supply). Germany co-authors automotive supplier standards (VDA, IATF) + EU CE/REACH enforced down-chain; Japan co-authors keiretsu/TPS supplier-governance + JIS. France (GlobalGAP), UK (BRCGS), Italy (luxury district governance) niche. China domestic-plus (BYD/CATL sourcing, GB, growing BRI reach). India/Russia/Canada/Brazil/SA chain participants adopting others' standards.

The UK imposes adjustment mainly through demand-side and final-market leverage — as a large consuming market it can push cost and disruption back onto suppliers in chains where it sits at the demand end — which lifts it to the Germany line despite a thinner manufacturing base. That consumption-side imposition, not supplier-network depth, is why it edges above eurozone exporters like France that absorb more chain adjustment through high foreign value added.

How the field was judged across the 12US imposes adjustment (demand-side leverage + lead-firm position + low input dependence for governance reasons). Eurozone members eat more adjustment (high FVA, interdependent). Russia low-FVA but as isolation, scored down on the governance reading.

UK firms hold a large outward stock and an open, services-and-finance-heavy corporate base that relocates production readily, placing it at 60. The exit threat is credible, but Britain is also an unusually open host, so it is as much relocated-into as relocating — a net-controller, not a dominant one.

How the field was judged across the 12Outward stock magnitude + lead-firm relocation capacity. Japan very high (9x out/in ratio = relocates abroad, little inbound). China large stock but more recent/state-directed.

At 55 the UK extracts host-state terms through its large, internationally-oriented firms, but its own openness as a host moderates the score. Britain bargains as a net-controller, yet it concedes terms to inbound capital nearly as readily as its firms win them abroad.

How the field was judged across the 12US dominant (largest firms + treaty-network authorship). Net-controller economies (JP/DE/FR/CA) score high; net-host economies (BR/IN) low. China's bargaining is state-mediated, mid.

At 58 the UK organizes a real share of the cross-border mode through its international firms, particularly in services and consumer sectors. It shapes how production is structured across frontiers as a net-controller, though less industrially dense than Germany or Japan.

How the field was judged across the 12US organizes the largest cross-border intra-firm mode (Apple/auto/pharma networks). Mirrors outward-stock control distribution.

The UK holds an unusually high outward-control stock for its size — 70 — a larger share of world stock than France (60) or Italy (40). British capital's grip on production sited abroad is one of its strongest structural assets, placing it well into the net-controller tier.

How the field was judged across the 12Pure outward-stock magnitude (% of world stock). US dominant; China rising; advanced economies high; BR/IN/RU/ZA low.

Post-Brexit the UK is an independent mid-tier voice that sets some terms in its own name for the first time since joining the EU, but it lacks the market leverage or bloc backing to author or block core multilateral terms. It participates and proposes as a sovereign actor without dominating the agenda.

How the field was judged across the 12US authors and blocks multilateral terms (Appellate Body block 2019-, drives plurilaterals). EU is WTO chief negotiator under exclusive competence — DE/FR/IT split by EU Council population share (DE .396/FR .324/IT .279) per D24: authorship is divisible, keyed to the double-majority QMV population threshold; was full-bloc D19. Japan CPTPP custodian; China rising rule-shaper via accession/plurilateral leverage; India defensive blocker (agric/development); UK post-Brexit independent mid voice; Canada coalition-builder (Ottawa Group); Russia/Brazil/SA coalition participants with limited individual authorship.

The UK is an adopter-plus: it rolled over the EU agreement templates it inherited and acceded to the CPTPP template rather than authoring a distinctive model of its own. It carries and extends others' templates rather than setting the benchmark, scoring in the lower-middle band.

How the field was judged across the 12US authors the high-standard template others benchmark (NAFTA/USMCA + TPP: IP, labour, ISDS, digital). EU DCFTA/Association-Agreement + Brussels-effect regulatory templates diffuse globally — DE/FR/IT split by EU Council population share (DE .396/FR .324/IT .279) per D24; was full-bloc D19. Japan CPTPP template steward; China rising template via RCEP/BRI; UK rolls over EU templates + CPTPP (adopter-plus); Canada co-shapes via CPTPP/CETA as partner; India/Russia/Brazil/SA largely adopt others' templates.

Post-Brexit the UK has a moderately large standalone import market conferring real but mid-tier denial leverage, well below the EU bloc's combined gatekeeping power it once shared. It can condition access but cannot dictate terms at the scale of the dominant deniers.

How the field was judged across the 12Denial = leverage of a large import market others need access to. US dominant (Section 301/232, tariff weaponization). EU large single market (DE/FR/IT = full EU denial value, D19). China large + uses access as leverage. Small/developing markets cannot deny.

The UK sets some surplus-capture terms where its firms author arrangements that allocate value, earning it a score in the EU brand/standards peer band. It holds real but bounded term-authorship rather than broad control of who retains the surplus across the production structure.

How the field was judged across the 12US sets surplus-capture terms (IP rents, platform economics, design margin). EU brand/standards rents (DE/FR/IT). China captures volume but sets fewer terms (margin-taker at frontier). Commodity economies low — rent ≠ terms-authorship.

The UK can shift some adjustment cost through its financial-center position and creditor channels, exercising partial imposition power. It scores in the European band — real leverage via the City and policy weight, below the US system-level capacity.

How the field was judged across the 12US dominant (IMF veto + dollar system forces others to adjust). EU bloc imposes via conditionality (DE/FR/IT). China rising via bilateral creditor leverage. Adjustment-BEARERS (IN/BR/ZA) score low.

The UK shapes some relative prices through its demand weight and pricing-influence in select markets, giving it partial terms-of-trade authorship. It sits below the US and China demand-scale shapers the basis names, with real but limited reach over how gains are allocated among producers.

How the field was judged across the 12Price-regime SHAPERS score high (US/China large demand sets benchmarks; USD invoicing). Commodity price-TAKERS (RU/BR/ZA) low despite high ToT index — outcome not authorship (the metric's whole point).

The gilt curve plus sterling's 7.5% share of international debt give London a genuine third price-setting anchor — smaller than the UST or the euro curve but a real reference the world prices some credit off (28). Through London's market depth the UK authors a distinct, if narrower, benchmark rather than merely taking others'.

How the field was judged across the 12US 95 — the UST curve is THE global benchmark others price credit off, USD 45.7% of international debt issuance; no rival on price-setting reach. Euro nations (DE/FR/IT) 48 — the euro risk-free curve (Bund) anchors EUR 40.3% of cross-border debt, the clear #2 benchmark, scored full-bloc per D19 (the curve is the union's, set collectively). UK 28 — gilt curve + GBP 7.5% of international debt, a real third anchor via London. Japan 14, Canada 10, China 10 — domestic curves, sub-1% international debt shares, little price-setting reach beyond their own paper. India/Russia/Brazil/South Africa 3-4 — no global benchmark role.

The Bank of England sits in the standing C6 swap network and extends sterling swap lines, giving it real outward backstop capacity in its own currency (35) — above the other national central banks but well below the Fed's system-wide dollar reach.

How the field was judged across the 12US 95 — the Fed is the world's dollar lender of last resort; its swap lines backstopped the entire global banking system in 2008 and 2020, the decisive Mexico-vs-Poland capacity Strange identifies. Euro nations (DE/FR/IT) 42 — the ECB is inside the C6 AND independently provides euro-liquidity backstop to others; scored full-bloc per D19 (one central bank, pooled). UK 35 — BoE in the C6 and extends sterling swaps. Japan 28, Canada 25 — BoJ/BoC inside the standing network, provide their currency's backstop. China 18 — extensive PBoC bilateral RMB swap network, but RMB is not a crisis-grade backstop and China is outside the dollar network. India/Russia/Brazil/South Africa 3-4 — no Fed line, no meaningful outward LOLR provision.

The UK is a Basel/FSB co-author and the global banking hub, home-supervising 3 G-SIBs; it punches above its bank count on rule-authorship, with London's centrality giving it outsized weight in writing the prudential terms the world's banks obey (70). Among national supervisors it ranks second only to the US on authorship.

How the field was judged across the 12Scored on two provision levers: authorship of the Basel/FSB rulebook the world's banks adopt, plus home-supervisor status of the 29 G-SIBs. US 90 — leads Basel/FSB AND home-supervises 8 G-SIBs, the most of any state; the dominant but not exclusive rule-author. UK 70 — Basel/FSB co-author, the global bank hub, 3 G-SIBs (punches above its bank count on rule-authorship). France 60 / Germany 55 — euro Basel seats; France home to 4 G-SIBs, Germany 1, both carry euro-bloc rule weight. Japan 45, Canada 40, Italy 40 — Basel/FSB members with 3/2/1 G-SIBs respectively. China 35 — 4 G-SIBs and a Basel/FSB seat, but a rule-taker more than rule-author on the global prudential bargain. India 12, Brazil 10, South Africa 8, Russia 6 — at the FSB table nominally but no G-SIBs and negligible authorship of the global rulebook (Russia further isolated).

Sterling carries about 6.5% of international payments and ranks #3 in FX spot, amplified by London's role intermediating global currency markets. The UK provides a genuine third settlement currency and a venue others route through, earning a 40 — real provision below the euro bloc but well above the secondary G7 currencies.

How the field was judged across the 12US 95 — USD 50.5% of intl payments and 80.7% of trade finance, the #1 settlement currency by a wide margin (the denomination rail). Euro nations (DE/FR/IT) 45 — euro 21.3% of payments / #2 in FX and trade finance, full-bloc per D19. UK 40 — GBP 6.5% payments + #3 FX spot + London intermediation. Japan 22 — JPY 3.5% payments, #5 FX. Canada 25 — CAD 3.0% payments, #6 FX (punches above size as a commodity/G7 currency). China 18 — CNY 3.1% payments but rising and #2 in trade finance (8.0%), a real but still-minor settlement role concentrated in its own trade. India/Brazil/Russia/South Africa 4-6 — currencies barely used for cross-border settlement.

Sterling accounts for roughly 7.5% of cross-border debt issuance, a real third currency that international borrowers use, though it prices no major commodity. The UK provides a genuine but minor debt-denomination rail, earning a 30 — above the secondary G7 currencies, well below the euro bloc and the dollar.

How the field was judged across the 12US 95 — USD 45.7% of international debt issuance AND the commodity-pricing currency (oil, metals), the dual lock the metric is built around. Euro nations 50 — euro 40.3% of cross-border debt (nearly matching USD on the debt face), full-bloc per D19; but the euro does not price commodities, so it trails USD on the combined construct. UK 30 — GBP 7.5% of debt, a real third currency. Japan/Canada 8-10, China 8 — sub-1% debt shares; commodities not priced in their currencies. India/Brazil/Russia/South Africa 3-4 — negligible debt-denomination and no commodity-pricing role.

The UK carries meaningful board weight but sits below the blocking threshold, so it cannot veto major decisions on its own. Its score captures relational influence as a senior member, not structural authority over what the institutions can and cannot do.

How the field was judged across the 12US 95 — sole holder of the blocking veto in both the IMF and the IBRD (the only member above the 15% threshold); structurally it alone can veto reform. All others are sub-threshold → relational influence only, scored on voting weight as a proxy for board sway: Japan/China ~6% → 18, the larger Europeans 13-16, down to South Africa 0.63% → 3. The gap from US to next is the structural fact.

The UK is part of the European bloc that supplies IMF leadership by convention and co-authors programme design, giving it real authority over the conditionality the institutions impose. It directs the agent as a senior member of the transatlantic management, not as a programme subject.

How the field was judged across the 12US 90 — sets the template for conditionality and holds the World Bank presidency by convention. France/UK/Germany 55-60 — the European bloc supplies the IMF Managing Director by convention and co-authors programme design (the transatlantic management duopoly). Japan 30, Canada 25 — meaningful G7 board voice. China 22 — large quota but a programme TAKER, building rival institutions (AIIB) outside this one. India/Brazil/Russia/South Africa low — programme recipients/peripheral to design.

The UK runs CHAPS, its sterling RTGS, giving it sovereign control of a real but modest clearing rail confined to its own currency's footprint. It governs the layer sterling must settle through, but sterling is a niche settlement unit beside the dollar and euro, so its provision is genuine yet limited.

How the field was judged across the 12US dominant: CHIPS (~$1.8tn/day, US-governed via The Clearing House) + Fedwire ($1,148tn annual) clear the dollar — the rail the world routes through. Euro RTGS (TARGET2, Eurosystem) gives DE/FR/IT a mid-tier bloc rail. China (CIPS) building but smaller; UK (CHAPS, GBP) modest; others minimal own-rail control. Positional: a fixed pool of world settlement sliced by who owns the clearing layer.

Post-Brexit the UK runs its own autonomous financial-sanctions regime through OFSI under SAMLA, designating and freezing access independently of the EU and US — a real, sovereign exclusion power. Its score reflects standalone capacity to deny financial access, a notch below the EU bloc's collective SWIFT leverage but genuinely its own to wield.

How the field was judged across the 12Power to cut access to the settlement system. US overwhelming — it directs exclusions with full extraterritorial reach (OFAC/SDN, SWIFT de-designation; tier: 'full extraterritorial exclusion'). EU secondary — can act collectively on SWIFT (DE/FR/IT 'real-lesser'); UK post-Brexit own OFSI regime (real-lesser). Others none. Positional: who can deny others access to the rail.

The UK runs no alternative to US-controlled settlement; sterling's CHAPS is its own currency's rail, not an escape from the dollar order the UK is broadly aligned with. Its floor-level score reflects an actor inside the mainstream settlement system with no independent route around it.

How the field was judged across the 12Who runs an independent rail escaping US control. China (CIPS) the main one — 194 direct + 1597 indirect participants, 126 countries, ~5100 banks reached (Mar 2026); the only state with a real alternative dollar-rail. Russia (SPFS) minor domestic substitute. EU (INSTEX) defunct/nil. US scored low BY DESIGN — it IS the mainstream rail, not an alternative — so China leads this provision-of-escape component. Positional: share of the capacity to route around US-controlled settlement.

Post-Brexit the UK runs its own OFSI sanctions regime, giving it genuine but mid-low independent designation capacity — it can name and freeze on its own authority. Yet it cannot deny access to a chokepoint others cannot route around the way the dollar issuer can, so its exclusion power is autonomous in form but limited in structural reach.

How the field was judged across the 12Capacity to exclude others from the financial system unilaterally. US overwhelming — full unilateral exclusion of the dollar/SWIFT chokepoint (Iran 2012, Russia 2022). EU collectively secondary (DE/FR/IT mid — can act on SWIFT in concert). UK post-Brexit own OFSI regime, mid-low. Others minimal. Positional: who controls denial of access to the chokepoint others cannot route around.

The UK's OFSI regime gives it slightly more standalone enforcement weight than its EU peers, but its sanctions still bind primarily its own persons and lack the dollar-clearing leverage that makes third-country conformity compulsory. It can pressure but cannot compel global compliance, placing it just above the European pack and far below the US.

How the field was judged across the 12Whose sanctions force THIRD-country compliance (secondary sanctions, dollar-clearing leverage). US uniquely extraterritorial — forces global third-country conformity. EU/UK far behind: no concept of secondary sanctions, EU passed a blocking statute to RESIST US secondary reach (measures bind only own nationals = primary). Others negligible. Positional: share of the capacity to make third parties conform.

The UK is the leading non-US asset-management hub: London's managers and intermediation infrastructure place a substantial slice of the world's investable capital, making it the clearest secondary provider of the allocation service beneath the American Big-Three.

How the field was judged across the 12US overwhelmingly dominant (63% of global AUM, the Big-Three). Positional: a fixed pool of the world's investable capital sliced among manager-domiciles — US holds the majority slice. UK (asset-mgmt hub) + France (Crédit Agricole/Amundi) the next tier. China's AUM is large but domestically-bound, not globally-allocating. Others minor.

UK-domiciled and UK-intermediated capital holds the largest non-US ownership slices across global strategic firms, reflecting London's role in placing equity — a genuine but clearly subordinate residual-claim position beneath the American Big-Three.

How the field was judged across the 12US dominant — the Big-Three are the largest or near-largest holders of most global strategic firms (the D18 attribution: TSMC/ASML power resolves to US capital). Positional: a firm's equity is a fixed pool sliced among holders; US holders take the largest slices. China owns its OWN champions (state + domestic funds) = a self-contained ownership bloc, scored modestly (owns inward, not the world's firms). Others hold scattered stakes.

The UK is the world's premier cross-border intermediation centre: London is where global equity allocation is routed and cleared, giving it the largest outbound portfolio-equity reach in the set. It is the clear secondary hub beneath the US — the channel through which much of the world's savings reaches global markets, a genuine provider role subordinate only to the American destination.

How the field was judged across the 12US + UK are the cross-border equity hubs (savings worldwide route into US markets; London the intermediation centre). SUPPORTING signal only — CPIS vintage spread (US 2011 vs JP 2022, India GAP) bars it from a clean cross-section, so it is weighted lightly and the score leans on the US-market-depth + AUM picture. India GAP flagged.

Second tier. BSI holds a meaningful set of secretariats and convenorships and remains an influential drafting voice in ISO/IEC, but its share places it below the US/Germany/China pole — a co-author, not the rule-pen.

How the field was judged across the 12Composite of secretariat-holding (the rule-pen) and convenorship (working-level steering). Germany/China/US form the top tier (DE leads secretariats, US leads convenorships, CN second on both — the rise of SAC is the standout structural fact). Japan/France/UK a clear second tier. Italy/Canada/India mid. Russia/Brazil/S.Africa low — participants, not pen-holders.

Second-tier shaper. The UK carries meaningful RFC-authorship weight and a long lineage in protocol engineering, contributing to the standards others build on, but it operates within a foundational stack governed and originated elsewhere rather than controlling it.

How the field was judged across the 12US overwhelmingly dominant — both by RFC authorship (6180, ~10x the next) AND by historical/custodial control of the foundational protocol stack (IETF origin, IANA/ICANN, root governance). Europe (DE/UK/FR) and China form a second tier on authorship volume; China rising. Basis note: the metric doc asks who *shapes*, not who *counts* — historical custody of the protocol stack (not author volume alone) anchors the US top score.

Rule-setter, not owner. The UK's DMCC regime gives it authority to set conduct and access conditions on the major platforms, a Brussels-effect-style rule projection — but it regulates platforms rather than owning them or controlling their access gates.

How the field was judged across the 12Anchored to the per-nation authority_tier below (rule-setting / access-denial, NOT user share). US is the structural platform gatekeeper — owns and sets access rules for the app stores, cloud, and mobile OS the world must route through, plus export-control-linked access denial. China second: a sovereign-walled parallel platform sphere (super-apps, HarmonyOS, domestic cloud) that gatekeeps the China market but is not yet globally gatekeeping. India/Brazil are market-gatekeepers (app bans, data-localization, court actions) over their own markets. EU states (DE/FR/IT) + UK are rule-setters-not-owners (DMA/DSA/GDPR / DMCC 'Brussels effect'), scored individually per D16. Russia sovereign-walled-minor; Canada rule-influence-minor; South Africa rule-taker.

The UK is the strongest of the second tier on origination, anchored by the DeepMind research lineage that produced genuinely frontier breakthroughs others built upon. It is a real source in selected AI domains — above its peers — but originates across too narrow a band to contest the leaders.

How the field was judged across the 12US is the origination frontier across domains (AI, biotech, internet, space). China the clear #2 and rising fast (frontier-model origination near-parity). UK/Germany/France/Japan/Canada a research-strong second tier (UK DeepMind-lineage, France Mistral, Canada AI-research depth). Italy/India/Russia mid (capacity but few frontier origins). Brazil/S.Africa low. This is where the metric surfaces 'leader vs follower' honestly.

The UK has a credible defence-research base and selective spillover into commercial technology, but its pipeline operates at second-tier scale. It converts some military innovation into commercial advantage without running the kind of dominant origination-to-market engine that defines the leaders.

How the field was judged across the 12US top — uniquely effective defence→commercial spillover engine (DARPA archetype,). China high on both spend scale AND a deliberate civil-military-fusion pipeline. Russia scores above its GERD rank on the MILITARY side (strong defence R&D) but weak commercial spillover. The score weights spillover EFFICIENCY + scale, not GERD alone — so China's spend lead does not flip the #1.

The UK has a credible frontier-model footprint through its leading AI-research lineage, placing it just behind France among the rest. It contributes to the frontier without controlling the compute stack others must access, leaving it a capable participant rather than a gatekeeper.

How the field was judged across the 12US controls the frontier-model + compute stack (top labs + the chip-design/cloud chokepoints it can deny — see technology-denial-regimes). China the only near-peer on frontier-model output (192 vs 210 since 2023) but compute-constrained by US export controls. France (Mistral) the strongest of the rest. Brazil/S.Africa/India/Italy near-zero frontier presence — genuine, not gaps.

The UK writes its own dual-use export-control lists post-Brexit and remains a Wassenaar member, so it authors denial rules in its own name rather than taking them. But its lists track the multilateral and allied frame closely and it commands no frontier chokepoint to write rules around, leaving it mid-tier — a real but derivative regime author, not an originator of the binding controls others must follow.

How the field was judged across the 12US dominant — authors the binding entity/chip-control lists others react to; Wassenaar is its multilateral frame. Japan/NL-tier (DE/FR/UK) author meaningful national controls + EU dual-use reg. China NON-member of Wassenaar but builds its OWN counter-denial (rare-earth/gallium export controls) — scored low here on WESTERN-regime authorship but note: China's denial capacity lives in indispensable-input-control (Production). Russia a member but no frontier tech to deny. Brazil/SA negligible.

The UK enforces its own export-control regime robustly within its jurisdiction and coordinates with allies, but post-Brexit it commands no extraterritorial instrument comparable to the FDPR to make third parties comply. It is a within-jurisdiction enforcer aligned to the allied frame, scoring in the lower-middle band — real enforcement, no third-party reach.

How the field was judged across the 12US near-monopoly on extraterritorial enforcement (FDPR + market access leverage). Japan scores as a COMPLIANT enforcer (implemented the 23-item SME controls July 2023) with some own reach. EU states enforce within EU dual-use frame. China has counter-enforcement (its own export-control law, unreliable-entity list) but limited extraterritorial bite — scored modest. Most others are rule-TAKERS who comply, not enforcers.

The UK retains pockets of critical technology and IP whose denial would matter in specific niches, but it commands no non-substitutable chokepoint in the frontier stack. Its criticality is modest — denial that bites at the margins, not a lever that can halt anyone's frontier progress — placing it alongside France.

How the field was judged across the 12US holds the most non-substitutable chokepoints (EDA, GPU design, key SME). Japan strong (SME). China scores MODEST here despite being the TARGET — because it now wields its OWN bite via rare-earth/gallium/germanium controls (non-substitutable inputs), a genuine counter-denial; but its advanced-tech denial capacity is limited. NL (the EUV monopoly) is the single most critical non-12 node. Most nations: nothing non-substitutable to deny.

The UK is a high-standard authoring state that helped build the Western IP regime and continues to carry independent weight in WIPO rule-making, distinct from the collective EU position. It shapes patentability and enforcement norms as a co-author rather than adopting them, scoring below the EU heavyweights' combined bloc weight but clearly on the author side rather than among the takers.

How the field was judged across the 12US dominant — TRIPS architect + ongoing regime-driver (Special 301, TRIPS-plus). EU bloc strong co-author (DE/FR/IT carry EU-negotiation weight on rule-setting). Japan high-standard adherent. China/India/Brazil/SA = the rule-TAKER / contesting bloc (India+Brazil+SA led the TRIPS-flexibilities / access-to-medicines pushback — genuine but DEFENSIVE agenda, scored modestly above pure takers). Russia low.

The UK runs a respected patent-enforcement judiciary whose courts have asserted jurisdiction to set worldwide licensing terms — most prominently the Unwired Planet v Huawei line in which the UK Supreme Court upheld setting a global FRAND rate as a condition of avoiding a UK injunction. That gives it exclusionary reach beyond purely domestic policing, though narrower than the US market-access lever, placing it just above the mid-tier European enforcers.

How the field was judged across the 12US near-unique extraterritorial exclusion (Section 337 import bans + market leverage). EU strong but bloc-internal (UPC from 2023 — DE the heaviest patent-litigation venue). China scores notably here — growing enforcement + anti-suit injunctions setting global FRAND rates (a real counter-reach). Most others enforce only domestically.

The UK punches far above its size as the anglophone co-author. Oxbridge, the LSE, and outlets like The Economist sit inside the agenda-defining circuit, so British-originated framing diffuses globally on the back of the shared English-language intellectual ecosystem. It does not set the paradigm alone, but it co-writes it rather than receiving it.

How the field was judged across the 12Scored from the per-nation authority_tier below (belief-conferral, NOT export volume). US is the paradigm-author — originates the dominant economic/policy paradigms and the agenda-defining academic + think-tank ecosystem (the modern Adam-Smith lever). UK is the anglophone co-author (Oxbridge/LSE, The Economist), punching above size. China is the rising counter-paradigm — the only state offering a coherent alternative belief-model at scale (state-led development, 'Chinese modernization'), though adopted more by dependency than voluntary conviction. France/Germany hold distinct tradition/model authority (Enlightenment/Francophonie; Ordoliberalism). India rising-civilizational; Russia spoiler-narrative; the rest regional/heritage voices.

The UK punches far above its size by riding the English lingua franca plus Oxbridge and the Russell Group, which together make it a destination system others operate in to be credentialled. It is the clear number two behind the US on this lever — a major provider of the language-and-credential standard rather than a taker of one.

How the field was judged across the 12The anglophone US-UK axis dominates — English as lingua franca + the top credential institutions + the student magnet. The US is the clear #1; UK punches far above size (language + Oxbridge/Russell Group). Canada/France mid (credential magnets in their language spheres). China scores modestly DESPITE rising universities — it is a net credential IMPORTER (Mandarin not a lingua franca; sends 1M+ students out). India high English-use but credential IMPORTER. The metric rewards whose system others OPERATE IN.

The UK co-exports rule-of-law and civic norms with real diffusion, carried partly through Commonwealth ties and the shared anglophone channel. Those norms are adopted, not merely broadcast, which gives it a strong upper-middle score as a genuine value-transmitter alongside the US rather than a passive relay.

How the field was judged across the 12Scored on belief ADOPTION, not media volume, from the per-nation authority_tier below. US is the default global value-set exporter (liberal-democratic, market, individual-rights norms). UK/France co-export rule-of-law / civic norms with real diffusion (Commonwealth, Francophonie). China is the genuine alternative-norm pole — development-without-conditionality and sovereignty-over-intervention norms adopted across parts of the BRI-linked Global South. Germany a regulatory/social-market norm-anchor; Russia diffuses sovereigntist counter-norms by affinity not authority; the rest narrower regional or aesthetic norm-sets.

The UK co-anchors the agenda channel alongside the US: Elsevier-RELX is UK-based and the top journals and venues concentrate heavily in the British academic ecosystem. It authors which knowledge counts through editorial and venue control, making it a channel-owner rather than a content-supplier.

How the field was judged across the 12US + UK dominate (Clarivate/WoS + Elsevier-RELX's UK base + the top journals/venues). Germany strong (Springer Nature). The rest are content PRODUCERS routed through Western channels, not channel-owners. China building rival indices (CNKI, its own journals) — rising but its researchers still chase WoS/Scopus indexing = channel-dependency. The metric scores who DECIDES which findings count.

The UK holds no independent global PNT channel and is not a member of the Galileo bloc that anchors the European orbital channel, leaving it more dependent than the EU bloc states on infrastructure it does not provide. Its score reflects channel-dependency, not authorship of a substitutable global system of its own.

How the field was judged across the 12US dominant — GPS (the default the world depends on) + Starlink's 65% LEO share. China #2: BeiDou (full global) + rising constellations. Russia: GLONASS (global but degraded). EU (DE/FR/IT) share Galileo = real bloc orbital channel. Japan/India regional PNT only. Brazil/SA = pure dependents, no orbital channel.

The UK retains meaningful channel rule-setting through its ITU presence, but as a non-member of the EU bloc it authors outside the European weight that amplifies Germany and France on spectrum and data-governance rules. It is a mid-tier rule-influencer — more than a taker, less than the bloc anchors that set the terms others must meet.

How the field was judged across the 12US leads (internet governance + heaviest ITU/orbital presence + GPS standard). EU bloc strong on spectrum + data-governance rules (Galileo + GDPR — DE/FR/IT bloc weight). China rising ITU influence + sovereign data rules + BeiDou standard. Russia ITU member with GLONASS standard. Others = rule-takers.
