US Banks Make Record Buybacks on Trump’s Looser Rules and Choppy Markets

There is a peculiar kind of irony in Wall Street’s first quarter of 2026. American equity markets endured their worst opening three months since the mini-banking crisis of 2023—rattled by a shooting war with Iran, an oil price spike that briefly pushed Brent crude past $120 a barrel, and a Federal Reserve that refused to blink. Yet inside the fortress balance sheets of America’s six largest lenders, a very different story was unfolding: a record-shattering cascade of cash flowing back to shareholders.

When the earnings releases landed this week, the numbers were extraordinary. JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs, and Morgan Stanley together spent approximately $32 billion on share repurchases in a single quarter—a figure that comfortably eclipsed analyst consensus expectations and, more importantly, signals that the Trump administration’s quiet dismantling of post-crisis capital rules is already reshaping the financial landscape in ways both celebrated and quietly alarming.

The record is not accidental. It is the logical, almost inevitable, consequence of a regulatory pivot that accelerated on March 19, 2026, when the Federal Reserve officially re-proposed a dramatically softened version of the Basel III Endgame framework—a moment that Wall Street lobbyists had spent three years and tens of millions of dollars engineering.

A Brief History of the Capital Arms Race

To understand why $32 billion in a single quarter is so remarkable, you need to remember what banks were doing with that money until very recently: hoarding it. The original 2023 Basel III Endgame proposal, drafted under Biden-era regulators, would have forced the eight largest US lenders to increase their common equity tier 1 (CET1) capital ratios by as much as 19%. The logic was defensible—the 2008 financial crisis exposed catastrophic capital inadequacy, and regulators globally wanted thicker shock absorbers. Banks pushed back furiously, running advertisements warning of reduced mortgage lending and constrained small-business credit. Quietly, they also began accumulating capital buffers in anticipation of stricter rules.

By the time Donald Trump won a second term and installed Michelle Bowman as Federal Reserve Vice Chair for Supervision—replacing the architect of the original proposal, Michael Barr—the largest US banks were sitting on an estimated $650 to $750 billion in projected cumulative excess capital over Trump’s presidency, according to Oliver Wyman analysis. That capital had to go somewhere. The March 2026 re-proposal gave it somewhere to go.

The new framework, per Conference Board analysis of the regulatory proposals, would reduce overall capital requirements at the largest banks by nearly 6%—a near-perfect inversion of what Biden regulators had sought. Critically, the GSIB surcharge, the extra capital buffer levied on globally systemically important banks, was also re-proposed for recalibration. JPMorgan CFO Jeremy Barnum captured the mood on this week’s earnings call, noting the bank currently measures some $40 billion in excess capital relative to today’s required levels—even before any final easing of the rules.

The $32 Billion Surge: Who Spent What

The precision of the data, pulled directly from SEC 8-K filings released this week, is striking. Here is where the capital went:

For context, the Big Six averaged roughly $14 billion per quarter in buybacks across 2021–2024, before accelerating to $21 billion in Q2 2025, according to J.P. Morgan Private Bank research. The Q1 2026 figure is more than double that historical average. Citigroup’s $6.3 billion was, as CEO Jane Fraser noted on the earnings call, the highest quarterly buyback in the bank’s history—a milestone at an institution that was technically insolvent in 2008 and reliant on a $45 billion government bailout.

The Regulatory Machinery: Basel III’s “Mulligan”

What regulatory observers are calling the “Basel III Mulligan” deserves careful unpacking for non-specialist readers. In simple terms: for three years, large US banks were required to hold more capital than rules formally demanded—essentially self-imposing buffers to prepare for what everyone assumed would be much stricter requirements. Those requirements never arrived in their original form. The March 2026 re-proposal, issued simultaneously by the Fed, FDIC, and Office of the Comptroller of the Currency, replaced the proposed 19% capital increase with a framework that, in many cases, delivers net capital relief rather than additional requirements, according to Financial Content analysis of the new rules.

The result is structurally elegant from a shareholder’s perspective: banks spent years building fortress balance sheets for a regulatory winter that has now been declared a false alarm. That excess capital—tens of billions of dollars per institution—represents a dammed river suddenly unblocked. The public comment period for the new proposals runs through June 18, 2026, meaning final rules remain months away. But banks are not waiting. The market signal from regulators is unambiguous, and buyback programs respond to signals, not final texts.

Bloomberg’s analysis had anticipated precisely this moment, noting that Trump-era regulators were moving toward a “capital-neutral” Basel III outcome that would unlock shareholder distributions at a scale not seen since before the financial crisis. What was predicted has duly arrived.

Chaos as Catalyst: How Market Volatility Amplified the Story

Here is where the narrative turns counterintuitive—and, for a certain class of investor, deeply satisfying. Conventional wisdom holds that banks struggle in choppy markets. In reality, the definition of “struggle” depends entirely on which side of the bank’s business you are examining.

The Nasdaq KBW Bank Index endured its worst first-quarter performance since the 2023 mini-banking crisis, dragged lower by fears about private credit contagion, the US-Iran conflict that erupted on February 28, and the so-called “March Oil Shock” that briefly paralyzed capital markets activity. Lending-sensitive banks faced NII compression worries. Credit quality concerns loomed.

And yet Goldman Sachs posted record equities trading revenue in Q1 2026. Goldman CEO David Solomon acknowledged rising volatility “amid the broader uncertainty” of the period, while noting that the bank’s results confirmed “very strong performance for our shareholders this quarter.” Citigroup’s markets and services divisions delivered double-digit growth precisely because volatility generates transaction volume—every hedge fund repositioning, every corporate treasury scrambling to cover commodity exposure, every sovereign wealth manager rebalancing away from dollar assets represents a fee opportunity for a well-capitalised trading desk.

The paradox is structural: volatile markets that suppress bank stock prices also generate the trading revenues that finance the buybacks that prop up those same stock prices. It is capitalism’s own form of recursion.

The Risks That Risk Managers Are Quietly Managing

Premium financial journalism demands more than celebration, and there are real risks embedded in this capital bonanza that deserve scrutiny.

Moral hazard and the memory hole. The explicit purpose of higher post-crisis capital requirements was to ensure that taxpayers would never again be asked to rescue financial institutions that had been permitted to lever up their balance sheets in pursuit of short-term shareholder returns. Reducing those requirements—even modestly—reverses that logic. As the Atlantic Council has noted in its analysis of global regulatory fragmentation, the Trump administration’s deregulatory stance is already prompting delays and dilutions elsewhere: the UK Prudential Regulation Authority has pushed implementation to January 2027, and the EU is debating further postponements. When every major jurisdiction softens simultaneously, the global backstop weakens simultaneously.

The buyback signal as inequality amplifier. Share repurchases concentrate wealth among existing shareholders—disproportionately institutional investors and high-net-worth individuals. A $32 billion quarterly return program at the six largest banks is, in distributional terms, largely a transfer to the top quintile of the wealth spectrum. That the same quarter saw Bank of America’s consumer banking division report loan charge-offs of $1.4 billion underscores the bifurcation: capital is being efficiently returned to shareholders while credit stress among retail borrowers persists.

Geopolitical tail risk remains unpriced. Jamie Dimon’s shareholder letter this spring referenced “stagflation” risks explicitly. The KBW Bank Index’s Q1 underperformance was a rational market signal that investors see non-trivial probability of scenarios—broader Middle East escalation, sustained elevated oil prices, a Federal Reserve forced to choose between inflation and growth—where these fortified balance sheets are tested in ways that would make the current buyback pace look imprudent in retrospect.

The Global Dimension: Europe, Asia, and the Regulatory Arbitrage Question

The implications extend well beyond American shores. European banks, which operate under stricter ongoing capital frameworks and face their own Basel III implementation challenges, are watching the US deregulatory sprint with a mixture of envy and alarm. EU lenders’ aggregate CET1 ratio sits at approximately 15.73%—comfortable on paper, but increasingly constrained relative to US peers now liberated to return capital more aggressively. European banks are lobbying Brussels for comparable relief, creating competitive pressure that risks a race to the bottom on global capital standards.

Asian regulators, particularly in Japan and Australia, have been broadly more faithful to Basel III implementation timelines. This creates a genuine regulatory arbitrage dynamic: US banks, freed from the capital drag of the original Endgame framework, can price risk more aggressively and pursue returns that more conservatively capitalised international peers cannot match. In the medium term, this may advantage Wall Street in global capital markets mandates—but it also means the US financial system absorbs more of the global tail risk.

What This Means for Investors in 2026 and Beyond

For retail and institutional investors parsing these numbers, a few practical observations:

The buyback surge mechanically reduces share counts, improving earnings per share metrics. Bank of America’s common shares outstanding fell 6% year-over-year; Citigroup’s EPS of $3.06 was materially aided by a smaller denominator. This is genuine value creation for patient long-term holders who have endured years of regulatory uncertainty weighing on bank valuations.

The deregulatory tailwind, however, is not infinite. JPMorgan’s Barnum was notably measured on the Q1 earnings call: “We prefer to deploy the capital serving clients,” he noted, flagging that buybacks at current market prices represent a second-best use of the bank’s firepower relative to organic growth or strategic acquisitions. Morgan Stanley’s relatively modest $1.75 billion repurchase—against peers spending multiples more—suggests not every institution is deploying excess capital at the same pace or conviction.

The next inflection points to watch: the Federal Reserve’s June 2026 stress test results, which will set new Stress Capital Buffers for each institution; the final form of the Basel III and GSIB surcharge rules expected by Q4 2026; and Citigroup’s Investor Day in May, where CFO Gonzalo Luchetti has signaled fresh guidance on the pace of repurchases following the nearly completed $20 billion program.

The Question That Lingers

There is a version of this story that reads simply as good news: well-capitalised banks returning excess capital to shareholders, generating trading revenues from market volatility, and demonstrating the resilience of a financial system that—unlike 2008—does not require emergency intervention. JPMorgan’s CET1 ratio sits at 15.4%. Bank of America’s at 11.2%. Even after the buyback blitz, these are not reckless institutions.

But there is another version of the story, less comfortable and ultimately more important. The capital that US banks are returning to shareholders this quarter was accumulated partly because regulators told them they needed it as a buffer against catastrophic, low-probability events. The decision to declare that buffer unnecessary was made not by markets, not by stress models, but by a political administration with a stated ideological commitment to deregulation. The question is not whether the system is resilient today. It is whether the memory of why the buffers existed in the first place will survive long enough to matter when it next becomes relevant.

Wall Street has a notoriously short institutional memory. History, unfortunately, does not.
