Four theses for the 2026–2030 regulatory cycle.
The boutique view — compressed to one page.
The next prudential cycle is not a continuation of the last. Basel IV is being productionised unevenly, Pillar 2 is being re-weaponised in a way the market has not priced, the GCC is running at twice the European pace, and the US Endgame will land on a timeline that is handed, not chosen. The four theses below are structural calls — testable, dated, and paired with observable indicators.
Level 1 is the paperwork. The operational phase is 2026–2028 — when the output floor transitions are fully phased, when more than one hundred EBA mandates crystallise, and when the banks that under-invested in data lineage discover the floor is not a capital metric but a data-governance one. Expect a cluster of G-SIB P2G moves driven by floor-related control gaps in 2027. The banks that rebuilt lineage early will outperform on disclosure quality and funding cost by 10–20 bps.
The ECB has signalled it intends to narrow the ‘zero-bps’ bucket and make reverse stress testing a first-tier input into SREP. The result will be greater dispersion of P2G across the SSM perimeter and a three-cycle memory effect that locks poor performers into elevated capital tax through 2030. Individual G-SIB outcomes will diverge by 50–100 bps. The banks rebuilding ICAAP, RST and JST relationship now will end the cycle at the top of the P2G distribution. The rest will not.
The CBUAE, SAMA and QCB are moving from rule-adoption to supervisory-capacity build. On current run-rate, the GCC's three largest systemic banks will be operating on a CRR3-equivalent framework, a mature stress-testing cycle, and a credible on-site supervision cadence by 2029 — ahead of the full US Basel-III Endgame production phase. GCC banks will therefore front-run the US on both disclosure quality and cross-border regulatory dialogue. European G-SIBs with Gulf subsidiaries should reset their booking-model assumptions; the cost-of-capital advantage of regional centres will narrow materially.
The US Endgame proposal as re-tabled will be softened on headlines but hardened on operational reporting, model validation and stress-testing. The operational consequence — the part the day-rate market will not sell — is that US regional and super-regional banks will converge toward the CRR3 operating-model inside three cycles, and the UK PRA will play bridge. European implementation experience becomes directly importable. The real cost of the Endgame is not the headline ratio. It is the build-out that the US banks have not yet priced into their 2026 capital plans.
Five-year prudential timeline · what actually moves
| Region | Dominant risk 2026–2028 | Dominant risk 2028–2030 | Ezelman call |
|---|---|---|---|
| 🇪🇺 EU | Output-floor productionisation. Data-lineage gaps surface in the first post-CRR3 SREP. P2G dispersion widens. | Pillar 2 dispersion. The banks that rebuilt RST and ICAAP through 2026–2027 take a visible capital-cost advantage. | Rebuild the ICAAP and RST now. P2G memory is three cycles. |
| 🇬🇧 UK | Basel IV UK Day-1. PRA framework diverges from CRR3 on leverage and RST expectations. | Convergence drift. PRA tightens behind US policy shifts; banks with EU-style infrastructure outperform. | Import CRR3 operating-model patterns. Do not rebuild from scratch. |
| 🇺🇸 US | Endgame re-proposal uncertainty. Business planning under unset capital rules. | Operational build-out. Reporting, validation, stress-test infrastructure catches up by 2030. | The headline is not the cost. The build-out is. Plan for a three-year operating-model rebuild. |
| 🇬🇨🇨 GCC | Supervisory capacity build. CBUAE, SAMA, QCB move from rule to on-site cadence. | Parity moment. GCC systemic banks reach European prudential parity — and on some dimensions lead. | The conversation is not ‘catch up’. It is ‘run’. Reset your booking-model assumptions. |
The outlook · compressed to one sentence per cohort
For CROs: 2026–2027 is your Pillar 2 rebuild window; the number is fixed in 2028. For CFOs: output-floor data-lineage is a 10–20 bps funding-cost call, not a compliance project. For Boards: reverse stress testing is the only lever you can personally pull on the P2G trajectory, and the ECB is now reading it as a governance artefact. For GCC C-suites: you are ahead of the narrative; act on the parity moment, don't wait for recognition.
