Washington is getting ready to potentially make life easier for the biggest US banks.
That can sound pretty abstract if you don’t strip it down to the mechanics. Regulators decide how much capital banks must keep to absorb losses and how much liquidity they need if funding starts to disappear.
More capital and more liquidity make banks sturdier, though they also limit how much money banks can lend, trade, or return to shareholders. Less of both gives banks more room to move while leaving a thinner cushion when conditions turn.
That tradeoff is now back at the center of US bank policy. On March 12, Federal Reserve Vice Chair for Supervision Michelle Bowman said regulators are preparing a softer rewrite of the long-disputed Basel III endgame rules, the post-2008 capital package Wall Street has spent years trying to weaken.
The new version could leave large-bank capital requirements roughly flat or slightly lower than current levels once related changes are included, and could free up more than $175 billion in excess capital across the industry. Surcharges for the largest global banks may also fall by about 10%.
That is a sharp turn from where the debate stood less than three years ago.
The earlier draft, pushed under Bowman’s predecessor, Michael Barr, in 2023, would have raised capital requirements at the biggest banks by about 19%. Banks argued that the proposal would make credit more expensive, reduce market-making capacity, and push activity out of the regulated system.
Their critics argued the opposite: years of easy money, concentrated asset exposures, and repeated stress episodes had made thicker buffers necessary. The new draft lands much closer to the banks’ side of that argument.
The contrast is especially striking for Bitcoin: while Washington appears ready to give large banks more flexibility on capital and liquidity, direct crypto exposure can still attract far harsher treatment, suggesting regulators remain more comfortable backstopping traditional balance-sheet risk than normalizing Bitcoin on bank books.
The real policy turn is bigger than capital
On its own, that would already be a major banking story. What gives it wider reach is the second piece moving alongside it: liquidity.
Earlier this month, Treasury officials said they were taking a fresh look at liquidity rules and floated an idea that would give banks some regulatory credit for collateral they have already prepositioned at the Federal Reserve’s discount window.
In plain terms, regulators may start treating part of a bank’s ability to borrow emergency cash as usable liquidity. Treasury described that borrowing capacity as “real, monetizable liquidity.”
That means banks may no longer need to carry quite as much dead weight if they can show they already have assets lined up at the Fed and can turn them into cash quickly. The system, in other words, is being redesigned around a more direct role for the central bank backstop.
For years, regulators tried to build a framework that would make banks self-reliant in a panic. They were supposed to hold enough liquid assets to survive a run and treat the Fed’s discount window as an emergency tool of last resort.
But in practice, banks have long avoided the window because using it is seen as a clear sign of distress. Treasury is now openly saying that this stigma is a problem and that the rules should better reflect the reality that the discount window exists to be used.
That lands differently only three years after the regional bank failures of 2023.
Silicon Valley Bank, Signature Bank, and First Republic collapsed because confidence vanished fast, depositors moved faster, and liquidity that looked available in theory proved much harder to mobilize in real time.
The Fed’s own review of SVB said the bank had serious weaknesses in liquidity risk management and that supervisors failed to fully grasp how exposed it had become as it expanded. The official answer then was straightforward: banks needed better oversight, better preparation, and stronger resilience.
The 2026 rewrite says the system also needs lighter capital requirements, a less punitive treatment of discount-window readiness, and fewer constraints on the biggest institutions.
More room for banks, less friction in the system
If the new framework goes through, large banks would have more room to extend credit, increase trading capacity, repurchase shares, and support deal activity.
Supporters say that’s exactly the point. Bowman argued that excessive capital requirements carry real economic costs and can interfere with banks’ basic job of supplying credit to the broader economy. Industry groups made the same case, saying the revised plan would align requirements more closely with actual risk.
The other side of that trade is just as clear.
Capital rules are a shock absorber, and liquidity rules are a form of brake. Ease both at the same time and banks get more freedom while the system carries less built-in friction. It moves the official balance away from maximum safety and toward efficiency, credit creation, and smoother access to Fed funding.
However, the Fed’s biggest problem now is timing.
Senator Elizabeth Warren warned against weaker capital standards while geopolitical and credit risks are already climbing. While her objection is political, it still nails the contradiction at the center of the debate.
After SVB, Washington said bank resilience had to come first. Now, with growth fears, market volatility, and funding sensitivity back in view, Washington is preparing to give the largest banks more room to breathe.
The consequences are simple.
This is a decision about how much slack to keep in the financial system before the next stress event arrives. A stricter framework will force banks to carry more idle protection. A softer one will accept a little more vulnerability in exchange for more lending, more market activity, and less drag on profitability.
Bitcoin’s critique of the banking system has always been strongest when policymakers expand the role of emergency support while presenting the overall structure as stable and self-contained.
The discount window isn’t a side detail in that story, but part of the infrastructure that keeps confidence from breaking all at once.
When Treasury starts arguing that prepositioned Fed collateral should count more directly in bank liquidity rules, it’s acknowledging that the system still depends on central-bank rescue architecture even in periods sold as normal.
A crisis isn’t near, but Washington is set on rewriting the post-SVB rulebook. This time, it wants to base it on a very pragmatic assumption, which is that when the next panic hits, the biggest banks need to have more flexibility and the Fed’s backstop needs to be easier to use without hesitation.
It’s certainly a much-needed relief for Wall Street.
For everyone else, though, it’s a reminder that the banking system is still being tuned around the same old problem: private risk-taking works best when public liquidity is always close at hand.
