Banks graded their own capital tests for a decade. Regulators just tried to stop that. The banks are winning.

What happened

US banking regulators are loosening how banks calculate the cash they must keep in reserve against potential losses. The change makes certain loans and trading positions count as lower-risk, which means banks can deploy more of their capital into lending and investments instead of holding it idle.

before decade-old capital rules, lower risk sensitivity

after modernized rules, higher risk sensitivity

Why this matters

For 15 years, since the 2008 financial crisis, banks have operated under capital rules designed to force them to hold real cash against the loans they make. This proposal softens those rules by reclassifying risk — some loans that were treated as risky now count as safer, which mathematically requires less reserve cash. The immediate effect is straightforward: banks get to lend more money with the same balance sheet. The structural question is whether regulators are genuinely updating outdated risk models or whether they're quietly eroding the post-2008 safety buffer. The agencies claim the new framework is more 'risk-sensitive' — meaning it better reflects actual default patterns — but that's the same argument made before every financial loosening.

Who wins, who loses

who wins Large US banks, which launched a television advertising campaign and congressional lobbying blitz and watched a sitting Fed chair publicly promise to rewrite the rule before it was ever finalized.

who loses Depositors and regulators who were counting on standardized capital floors, which collapsed under the weight of 400 negative comment letters and a change in administration.

The signal

Why this hasn't landed yet

It reads as a technical amendment to existing capital ratios, the lobbying campaign happened in 2023 and 2024 and has already been covered as a political story, and the freeze makes it feel resolved when it is actually unresolved in a consequential direction.

What happens next

The Trump administration's regulatory freeze leaves the re-proposal in limbo; the next move belongs to the bank regulators under the new administration, who will likely either quietly bury it or issue a scaled-back version that preserves most internal model discretion, probably within 12 to 18 months.

The catch

The large US banks, having already forced one re-proposal by flooding the comment process and running a television ad campaign, are now waiting for the regulatory freeze to expire so they can argue the scaled-back version still needs scaling back.

The longer story

The longer arc

The 1996 Basel I market risk amendment created the internal-models regime this proposal would end; Basel II, finalized by US regulators in July 2007 and effective April 2008, was overtaken by the crisis it was meant to prevent within months of taking effect; Basel III was the post-2008 repair job, implemented in the US starting in 2013; this proposal is the piece Basel III left unfinished, arriving sixteen years later and still not done.

Part of a pattern

The UK and EU have also delayed their Basel Endgame implementations, each citing US inaction as justification, meaning the coordinated international capital reform that was supposed to close the gaps exposed in 2008 is now stalled across every major Western banking jurisdiction simultaneously.
