The Powell Perspective: Are Regulators Forgetting the Lessons of 2008?

WASHINGTON, D.C. – June 18, 2026 – More than fifteen years after the global financial crisis brought the world economy to its knees, a battle over its most important lessons is once again raging in Washington. On one side, U.S. banking regulators are advancing a plan to soften capital requirements for the nation's largest banks. On the other, a council of distinguished financial experts is sounding the alarm, warning that these moves are a dangerous step backward that could resurrect the specter of “Too Big to Fail.”

In a sharply worded public comment letter, the CFA Institute Systemic Risk Council (SRC), a nonpartisan group of former policymakers and financial experts, has condemned the latest proposals to finalize the Basel III international capital standards. The SRC argues that the plan, known as the “Basel Endgame,” dangerously weakens the very safeguards designed to prevent another taxpayer-funded bailout.

SRC Cochairs Simon Johnson and Erkki Liikanen, in a joint statement, did not mince words: “The SRC acknowledges that the proposals contain constructive elements and that it is important to complete the Basel reforms. Unfortunately, the proposals exacerbate systemic risk vulnerabilities and intentionally ignore certain Dodd-Frank Act requirements designed to prevent taxpayer funded bailouts.”

The Great Regulatory Reversal

At the heart of the dispute is a dramatic pivot by U.S. regulators. In July 2023, following the regional banking turmoil that saw the collapse of Silicon Valley Bank, regulators proposed a tough new framework that would have increased capital requirements for large banks by an estimated 16%. The move was seen as a decisive step to bolster the financial system's resilience.

However, after a year of intense lobbying from the banking industry, regulators unveiled a stark reversal in March 2026. This new proposal doesn't just walk back the 2023 plan; it actively reduces capital levels from their current state. Under the revised framework, the largest, most systemically important banks (GSIBs) would see their core equity capital requirements fall by approximately 4.8%, with large regional banks seeing a 5.2% reduction. The total system-wide capital relief is estimated at nearly $88 billion.

Regulators have framed this reversal as a “modernization” effort, arguing the reductions are “reasonable given the evolution of large bank capital requirements over the last decade.” The goal, they claim, is to simplify rules and enhance bank competitiveness without compromising safety. Yet, critics see the fingerprints of industry pressure all over the new proposal, which offers banks more balance sheet flexibility that could be used for anything from increased lending to share buybacks and acquisitions.

Echoes of 2008: The Return of Systemic Risk?

The SRC’s central fear is that this regulatory easing unravels the hard-won stability forged after the 2008 crisis. Bank capital is the essential buffer that allows a financial institution to absorb unexpected losses without collapsing or requiring a bailout. For the SRC, reducing these buffers—especially after they claim regulators have already made “downward adjustments to leverage ratios and loss-absorbing capacity in the past two years”—is a recipe for instability.

The hidden cost of this progress, from the SRC's perspective, is the reintroduction of severe systemic risk. The council highlights the unique danger posed by GSIBs, whose vast and interconnected operations mean that “even small reductions in capital buffers can have outsized consequences for the economy.” When these behemoths become fragile, the entire financial system is threatened.

This isn’t just a theoretical exercise. The SRC warns that the new rules effectively ignore the spirit, if not the letter, of the Dodd-Frank Act, the landmark legislation passed to end the era of “Too Big to Fail.” By lowering the resilience of the largest banks, the proposal increases the likelihood that in a future crisis, the government would once again be forced to choose between a catastrophic economic collapse and a deeply unpopular public bailout.

A Battle of Evidence and Economic Futures

The debate over the Basel Endgame has become a battle of competing narratives about the future of the economy. Proponents of the softer rules, including powerful banking lobbies, argue that high capital requirements stifle economic growth. They claim stringent rules restrict lending, hinder U.S. banks’ ability to compete globally, and reduce liquidity in critical markets, such as the one for U.S. Treasury bonds.

However, the SRC forcefully pushes back on this narrative, stating that the regulators’ justifications for easing capital are not supported by the evidence presented. “Several justifications in the Proposals for easing capital requirements are not supported by the analysis presented,” the council notes, adding that regulators “provide little evidence” for claims that existing rules significantly harm lending or market liquidity.

The SRC is demanding a higher standard of proof. It urges policymakers to ground any changes in “current data and rigorous economic impact analysis,” with clear evidence that the revisions will not undermine financial stability. The council also calls for regulators to assess the aggregate impact of all recent capital reductions, arguing that a piecemeal approach obscures the true erosion of bank resilience.

For businesses and households, the outcome of this technical debate has tangible consequences. It will determine the cost and availability of credit, the stability of the financial system, and ultimately, who bears the risk of a future downturn. The core question is one of priorities: should we optimize for short-term economic efficiency, or should we fortify the system for long-term stability?

A Call for Prudence

As the public comment period for the controversial proposal closes today, the SRC is urging regulators to change course. Their recommendations are clear: avoid weakening core capital requirements and instead maintain or strengthen existing protections, especially for the largest and most complex banks. They advocate for remaining aligned with strong international standards while preserving robust U.S. safeguards, arguing that resilience, not lighter regulation, is the true source of competitive advantage.

“The lesson of the financial crisis is clear: strong capital standards are the foundation of a stable financial system,” Johnson and Liikanen concluded. “We should not roll back safeguards without compelling evidence that doing so will serve the broader public interest.”

Regulators now face the critical task of weighing the industry's calls for flexibility against the stark warnings that the financial system’s post-crisis safety net is being quietly dismantled.
