The Quiet Retreat: Analyzing a Decade of Declining Bank Enforcement
Executive Summary: A Regulatory Shift
A comprehensive analysis of U.S. banking enforcement data from 2015 to 2025 reveals a profound transformation in how the nation’s top financial regulators oversee the industry. According to new research from the Brookings Institution, led by Aaron Klein and Ian Connell, the three primary federal banking regulators—the Federal Reserve (Fed), the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC)—have overseen a marked decline in formal enforcement actions.
Contrary to the long-standing political narrative that financial regulation operates like a pendulum, swinging aggressively between Democratic and Republican administrations, the data suggests a more permanent "ratchet effect." Rather than surging under Democratic leadership and receding under Republican oversight, the propensity to initiate formal enforcement has seen a consistent, long-term erosion, with the Federal Reserve emerging as the outlier in its retreat from rigorous oversight.
Chronology of Oversight: A Decade of Change
To understand the current state of banking supervision, one must look at the structural evolution of the industry over the last ten years. Between 2015 and 2025, the U.S. banking landscape underwent a period of rapid consolidation. The number of active lenders plummeted by approximately 30%, shrinking from 6,182 institutions to 4,336.
- 2015–2017: This period, characterized by the final years of the Obama administration, saw enforcement levels that would later be viewed as the "high-water mark" for modern oversight. The departure of Fed Governor Daniel Tarullo in 2017 marked a symbolic and functional turning point for the Federal Reserve’s supervisory posture.
- 2017–2021: The first Trump administration ushered in a shift in regulatory philosophy. While some expected a total dismantling of post-2008 oversight, the data suggests a more nuanced "ratchet" effect, where enforcement actions were curtailed and never fully recovered even when political winds shifted in 2021.
- 2021–2025: Despite the Biden administration’s promises of tougher oversight, the aggregate data shows that enforcement actions remained at historically depressed levels. The period between 2023 and 2025 saw an average of only 263 annual enforcement actions across all three agencies, a significant drop from the 341 recorded between 2017 and 2019.
Supporting Data: The Widening Disparity
The Brookings research highlights a critical divergence between the agencies. When controlling for the number of banks each agency oversees, the trends become stark. The banking sector has seen the following decline in the number of supervised entities:
- OCC: 36% decline in overseen banks.
- FDIC: 31% decline in overseen banks.
- Federal Reserve: 16% decline in overseen banks.
When researchers adjusted these figures to account for the shrinking population of banks, the OCC actually appeared to increase its enforcement intensity. The FDIC remained relatively flat, but the Federal Reserve’s decline in enforcement became even more pronounced.
Comparative Enforcement Averages
| Agency | 2017–2019 Annual Avg | 2023–2025 Annual Avg | Change |
|---|---|---|---|
| FDIC | 168 | 126 | -25% |
| OCC | 91 | 95 | +4.4% |
| Fed | 81 | 42 | -48% |
The most alarming statistic is the Fed’s performance: enforcement actions have plummeted by more than 58% since the departure of Daniel Tarullo. This suggests that the Federal Reserve has moved toward a model of "supervisory light," raising questions about whether this shift contributed to the catastrophic failure of Silicon Valley Bank (SVB) in 2023.
The Silicon Valley Bank Case Study
The collapse of Silicon Valley Bank serves as a grim case study for the consequences of this regulatory drift. When the Fed reviewed its own role in the collapse, the internal report was scathing. It characterized the supervisory approach as "too deliberative and focused on the continued accumulation of supporting evidence in a consensus-driven environment."
This admission of failure suggests that the Fed’s internal culture had become paralyzed by a desire for absolute consensus, leading to a paralysis in taking timely, decisive action. Klein and Connell raise a provocative question: Does this culture of "consensus-driven delay" exist across the entirety of the Fed’s supervisory staff, or was it an isolated failure?
If the Fed continues to prioritize evidence-gathering over preemptive intervention, the systemic risks to the banking sector may grow as banks become more adept at exploiting this "deliberative" lag.
Official Responses and Philosophical Shifts
The Federal Reserve has recently moved toward new supervisory principles that have raised eyebrows among policy analysts. These principles suggest a higher bar for initiating enforcement actions and explicitly encourage examiners to "give greater deference to banks’ own conclusions" regarding the remediation of problems.
Critics argue that this is a fundamental abdication of the supervisor’s role. If an examiner is instructed to defer to a bank’s self-assessment, the adversarial, independent nature of supervision is effectively neutered. The Fed, however, maintains that this approach fosters a more collaborative environment.
The researchers argue that there are only two logical conclusions regarding the Fed’s current state:
- Compliance Superiority: Banks under Fed supervision have become significantly more compliant than their peers overseen by the OCC or FDIC.
- Regulatory Failure: The Fed has willfully retreated from its mandate, either by choosing not to elevate problems to the level of formal enforcement or by suffering from a systemic ignorance of the risks developing within its own regulated entities.
Implications for the Future of Financial Stability
The implications of this research are profound for both the banking industry and the broader U.S. economy. If the "ratchet effect" is indeed real—meaning that enforcement mechanisms are being systematically dismantled regardless of which party occupies the White House—the U.S. financial system is becoming increasingly reliant on the self-regulation of its largest entities.
1. Systemic Risk
The primary risk is the "too big to fail" dynamic combined with "too soft to regulate." If enforcement is no longer a credible threat, large financial institutions may be emboldened to take on excessive risk, secure in the knowledge that examiners will prioritize consensus and remediation over immediate sanctions.
2. Regulatory Arbitrage
As the OCC maintains a more consistent enforcement posture while the Fed retreats, there may be an incentive for banks to seek charters that place them under the Fed’s umbrella. If one regulator is perceived as "softer" than others, it creates a competitive disadvantage for those who enforce the rules strictly.
3. The Myth of the Pendulum
Perhaps the most significant contribution of the Brookings analysis is the debunking of the political pendulum myth. By demonstrating that the decline in regulation is a structural, long-term trend, the authors challenge the notion that voters can easily "vote in" stricter oversight. If the regulatory apparatus is structurally inclined toward less enforcement, then administrative changes in Washington may be merely performative.
Conclusion: A Call for Transparency
As the industry looks toward the next phase of the 21st century, the data provided by Klein and Connell demands a response from regulators. The Federal Reserve, in particular, must address whether its "consensus-driven" culture is compatible with its mandate to maintain financial stability.
Without a return to more aggressive, independent, and timely enforcement, the gaps in oversight that led to the collapse of SVB may continue to widen. The "ratchet" of regulatory retreat is a trend that, if left unchecked, may leave the American taxpayer holding the bag for the next banking crisis—a crisis that, by all accounts, could be avoided if the regulators simply did their jobs.
Moving forward, transparency in the enforcement process will be key. If regulators are going to defer to the banks they oversee, the public deserves to know exactly why and under what criteria. Otherwise, the banking sector faces a future where the rules exist on paper, but the enforcement of those rules has become a relic of the past.
