G3 central-bank axis
Composition
Federal Reserve (US, dollar-issuing, global lender of last resort by virtue of swap lines), European Central Bank (Eurozone-19, second-largest reserve currency), Bank of Japan (carry-trade anchor, lowest-rate G3 issuer historically). BIS (Basel) hosts the standing committees, the BIS Innovation Hub, and the cross-CB statistical infrastructure but does not vote on rate decisions.
The bloc is durable on crisis coordination (2008 swap lines, 2020 swap-line activations, 2023 SNB / Credit Suisse coordination) but heterogeneous on policy divergence. Treat as one player when cross-CB action is observable (joint swap-line announcements, coordinated FX intervention, joint BIS innovation moves). Treat as three on quarterly rate decisions.

Interpretations
Incentives (current)
Opened 2026-05-03 · Supporting: 0
- Fed: maintain price stability mandate (PCE ~2%) while preserving employment-side credibility; preserve global-reserve-currency status against alternative-rail momentum
- ECB: navigate inflation-vs-fragmentation trade-off across heterogeneous Eurozone economies; preserve ECB independence against political pressure (German hawks, French / Italian doves)
- BoJ: exit yield-curve control without triggering disorderly JGB selling or yen overshoot; rebuild policy space against next downturn
- All: preserve cross-CB coordination credibility for next crisis (swap lines as bedrock)
Dominant strategy (current)
Opened 2026-05-03 · Supporting: 0
Pause with bias toward Tighten or Ease per individual CB conditions. Strategy menu per nash-framework.md §1.5.2: Tighten ↔ Pause ↔ Ease. Fed pause-with-cut-bias since 2024H2; ECB pause with cut-bias; BoJ pause with hike-bias (the inverse of the other two). Divergence is the live read, not a coordinated stance.
Coherence read
Opened 2026-05-03 · Supporting: 0
Bloc holds on crisis coordination; diverges on policy direction. Risk vectors: (1) Fed pivot forced by US fiscal stress (debt-service-to-GDP threshold) decoupling from ECB / BoJ; (2) BoJ disorderly exit triggering global-bond-market dislocation; (3) ECB fragmentation crisis requiring outright OMT activation, distancing from Fed comfort zone.

Open questions
- At what US debt-service-to-GDP threshold does the Fed reaction function structurally shift toward fiscal-dominance posture?
- Does BoJ exit YCC fully before the next global downturn forces the question?
- How does the bloc respond if Chinese / BRICS payment-rail experimentation (mBridge, CIPS) reaches scale that materially erodes dollar-clearing centrality?
