Do regulators finalize the re-proposed Basel III Endgame capital rules?
Will the Federal Reserve, OCC and FDIC jointly issue a final rule adopting the March 2026 re-proposed Basel III Endgame bank capital requirements, rather than further delaying, substantially revising, or abandoning that re-proposal?
Leaning toward eventual finalization — this version lowers rather than raises capital requirements, giving regulators and banks aligned incentives to finish it, but the original proposal's multi-year stall is a real precedent for delay
The case for finalization: this re-proposal is explicitly bank-favorable (lower capital requirements rather than higher), removing the intense industry opposition that stalled the 2023 version for years, Governor Bowman has publicly signaled the agencies intend to move soon, and the comment period has already closed. The case against, or for further delay: the original 2023 Basel III Endgame proposal took more than two years and was ultimately scrapped rather than finalized in its original form, the UK has already pushed back its own Basel timeline specifically citing US delay as the reason, and no agency has committed to any public target date even four months after the comment period closed.
No fixed date · The three agencies re-proposed the rule on March 19, 2026; the public comment period closed June 18, 2026; Bloomberg Intelligence has projected possible finalization in late 2026 with phase-in from 2027, but no agency has set a public target date
Federal banking regulators re-proposed Basel III Endgame on March 19, 2026, describing it as the most significant reset to the capital regime in more than a decade, with lower minimum risk weights, less conservative methodologies and a narrower market-risk framework expected to reduce overall capital requirements industry-wide — a sharp contrast to the original 2023 version, which raised requirements and drew heavy bank opposition before stalling for years. The public comment period closed June 18, 2026, and Fed Governor Michelle Bowman has said changes to capital rules are 'coming soon,' but no agency has committed to a specific finalization date. No final rule had been issued as of this run.
The agencies either jointly publish a final rule adopting the re-proposal or they don't — delaying indefinitely, withdrawing it, or replacing it with a further-revised version — a discrete regulatory action with no partial outcome.

What do you think?
Take a side
Regulators finalize the rulethis is “yes”
This re-proposal lowers rather than raises capital requirements, removing the intense industry opposition that stalled the original 2023 version for years, and Fed Governor Bowman has publicly signaled the agencies intend to move soon now that the comment period has closed.
Worth knowing: No agency has committed to a public target date even four months after the comment period closed — 'coming soon' from a Fed governor is a signal of intent, not a confirmed schedule.
Finalization stalls or the re-proposal is shelved
The original 2023 Basel III Endgame proposal took more than two years and was ultimately scrapped rather than finalized, the UK has already pushed back its own Basel timeline specifically citing US delay, and bank regulatory rulemaking has a documented history of slipping past informal targets.
Worth knowing: Unlike the original version, this re-proposal faces little organized industry opposition — the usual reason Basel rulemakings drag on for years is largely absent this time, which argues against assuming the same multi-year delay repeats.
