Trump Regulators Slash Wall Street Capital Requirements in Sharp Reversal
The Trump administration cut bank capital requirements by up to 7.8 percent, upending Biden-era rules and potentially unlocking $2.6 trillion in new lending capacity across the U.S. economy.
Three years after regulators unveiled the toughest bank capital rules since the 2008 financial crisis, the Trump administration executed a sharp reversal on March 19 — slashing capital requirements for Wall Street banks by 4.8 percent and handing regional lenders even deeper cuts.
The announcement upends a 2023 proposal that would have forced the largest banks to hold roughly 20 percent more capital. The new package does the opposite: a 5.2 percent reduction for larger regional banks and a 7.8 percent cut for institutions with assets under $100 billion — freeing capital that banks and their supporters argue has long sat idle under rules too blunt to serve the economy they were meant to protect.
Capital requirements are the reserves regulators force banks to hold to absorb losses when loans sour or markets crash. The original 2023 rules emerged in response to Silicon Valley Bank's collapse, which exposed cracks in the oversight framework. The new rules also end the requirement that banks deduct mortgage servicing assets from regulatory capital, replacing it with a 250 percent risk weight.
The global systemically important bank surcharge will be reindexed to economic growth for the first time in more than a decade. Surcharges will be assigned in 10 basis point increments instead of 50, while the short-term wholesale funding component shrinks from roughly 30 percent to 20 percent of the calculation — a technical shift with sweeping practical consequences for how much capital banks must park on the sidelines.
Federal Reserve Vice Chair for Supervision Michelle Bowman previewed the proposals March 12 at the Cato Institute, arguing that regulatory excess had gone too far. "Continuously increasing capital levels without a specific purpose imposes real economic cost," Bowman said. "When capital requirements become excessive, they impair the banking system's fundamental function of providing credit to the real economy."
Industry groups rallied immediately. The American Bankers Association, Financial Services Forum, and Bank Policy Institute issued a joint statement praising what they called a "welcome focus on risk-sensitivity." Cliff Rossi, a finance professor at the University of Maryland, framed the shift as precision over blunt force. "This is really about creating smarter capital rules than we've had in the past," Rossi said. "They're more refined. They're taking more of a surgical approach to it."
Not everyone sees the scalpel. Sen. Elizabeth Warren, the Massachusetts Democrat who has long pushed for stricter bank oversight, characterized the rollback as a win for Wall Street lobbyists. "Three years ago, Wall Street launched an unprecedented lobbying attack to kill rules that would have prevented big banks from loading up on excessive debt to fund their risky trading operations and other activities," Warren said. "Trump's bank regulators, once again, are handing the big banks exactly what they want — a weak rule that fails to address the severe flaws in the capital framework that were never fixed after the 2008 financial crisis, leaving our entire economy at risk."
Fed Governor Michael Barr, who advocated for stronger capital rules under the Biden administration, dissented on related stress testing changes. He called the changes "unnecessary and unwise" and warned that weakening supervision may allow real dangers to accumulate beneath the surface.
The capital proposal arrives as part of a broader deregulatory push. On March 13, President Trump signed an executive order directing federal agencies to overhaul mortgage lending rules and expand credit access. In November 2025, regulators finalized a rule modifying the enhanced supplementary leverage ratio that reduces tier 1 capital requirements by less than 2 percent, effective April 1. That same month, agencies proposed lowering the community bank leverage ratio requirement from 9 percent to 8 percent — moves that together form a coordinated effort to ease regulatory burdens across the sector.
The stakes are not abstract. An analysis from Alvarez & Marsal estimated the full package could unlock $2.6 trillion in lending capacity by freeing capital currently held as regulatory buffers. Morgan Stanley estimates large banks currently hold roughly $175 billion in excess capital above existing requirements — funds that, under the new rules, could flow into loans or shareholder returns rather than sitting in reserve.
The proposals must clear a 90-day public comment period before finalization. Implementation could extend into 2027, depending on how regulators respond to feedback from banks, consumer groups, and state officials.
At its core, the debate is about who bears the cost of caution — and who pays when caution runs short. The Trump administration has placed its bet on growth over guardrails. Whether $2.6 trillion in liberated capital lifts the economy or someday strains it, the answer won't arrive before the ink dries.
