Bank Deregulation Modernizes Finance

• Alan Greenspan was the assumption's most consequential champion. As Federal Reserve Chairman for nineteen years beginning in 1987, he brought to the role a settled conviction that self-regulating financial markets were not merely efficient but morally superior to government-directed alternatives. He pressed Congress directly for repeal of Glass-Steagall, warning that banks would become "dinosaurs" if the separation was not lifted, and testified in favor of H.R. 10 in 1997, the legislation that would eventually become the template for the Gramm-Leach-Bliley Act. ^[7][8] His argument was that the separation was a historical artifact of a crisis that had been misdiagnosed, that modern risk management had rendered the old fears obsolete, and that allowing banks to affiliate with securities firms and insurers would modernize American finance without endangering insured deposits. ^[7] His institutional authority gave these arguments a weight that academic papers alone could not have provided, and his public statements were treated by Congress and the press as the considered judgment of the nation's foremost financial steward. The 2008 crisis prompted his famous admission before Congress that he had found a "flaw" in his ideology, but by then the architecture he had championed had been in place for nearly a decade. ^[2]
• Brooksley Born occupied the opposite position with equal clarity and considerably less institutional reward. As chair of the Commodity Futures Trading Commission in the late 1990s, she raised formal alarms about the risks accumulating in unregulated derivatives markets and pushed for oversight authority over instruments that were growing rapidly outside any regulatory perimeter. ^[2][5] Her warnings were met with a coordinated effort by Greenspan, Treasury Secretary Robert Rubin, and Deputy Secretary Lawrence Summers to strip her agency of jurisdiction and prevent any rulemaking. She left the CFTC in 1999. The derivatives market she had warned about grew to tens of trillions of dollars in notional value before the crisis, and the instruments she had sought to regulate were central to the transmission of losses through the financial system in 2008. ^[2]
• Saule Omarova, a Cornell law professor and scholar of financial regulation, represented a later generation of critics who challenged the consolidation thesis on structural grounds. She argued that banks were not merely private firms subject to market discipline but government franchises operating with public subsidies, including deposit insurance and Federal Reserve access, and that this status carried public obligations that deregulation had systematically eroded. ^[1][5] President Biden nominated her as Comptroller of the Currency in 2021. The banking lobby opposed her confirmation vigorously, and she withdrew her nomination after it became clear she lacked the votes. The episode illustrated that the institutional forces that had built the deregulatory consensus retained sufficient power, decades later, to block a critic from the agency that charters national banks. ^[1]
• Ben Bernanke, who succeeded Greenspan as Federal Reserve Chairman in 2006, later acknowledged that regulatory gaps had amplified systemic vulnerabilities, and described the 2008 crisis as the worst in global financial history, surpassing even the Great Depression in certain respects. ^[2][5] He had operated within the deregulatory framework during his tenure and did not publicly challenge its premises before the crisis. His subsequent acknowledgment of the gaps was significant as an institutional admission, but it came after the damage had been done.

The Federal Reserve Board was the deregulatory assumption's most powerful institutional sponsor. It declined to use its authority under the Home Ownership and Equity Protection Act of 1994 to regulate predatory mortgage lending standards, a decision that allowed subprime origination practices to expand unchecked through the early 2000s. ^[2][5] It coordinated with other federal bank regulators to lobby Congress for Glass-Steagall repeal, with Greenspan using formal testimony and public statements to advance the case. ^[7] The St. Louis Federal Reserve published articles endorsing the Gramm-Leach-Bliley Act as creating a new competitive banking universe comparable to universal banking systems in Europe and Asia, framing consolidation as a straightforward modernization rather than a structural transformation with distributional consequences. ^[6] The Board of Governors formally endorsed H.R. 10 in 1997 as a means to improve financial efficiency and competitiveness while containing risks, providing congressional testimony that treated the manageable-risk conclusion as settled. ^[8]

The financial services industry spent $2.7 billion lobbying Congress in the decade before the 2008 crisis, a figure that bought not merely favorable legislation but a sustained alignment between industry preferences and regulatory philosophy. ^[2] The banking lobby unified after the deregulatory wave of the 1980s, aligning with Republican administrations and anti-government sentiment among bankers who had been squeezed by high interest rates in the post-New Deal period. ^[1][5] Fannie Mae and Freddie Mac used their considerable political influence to resist tighter regulation of their operations throughout this period, deploying lobbying resources and congressional relationships to fend off oversight proposals that might have constrained their expansion into riskier mortgage products. ^[2][5]

Citigroup served as the era's emblematic institutional creation. Formed in 1998 from the merger of Citibank and Travelers Group, it was assembled before Gramm-Leach-Bliley formally permitted such combinations, on the assumption that the law would change in time to legalize what had already been done. ^[6] It became the largest financial institution in the world and a walking demonstration of the universal banking model that deregulation's proponents had promised would deliver efficiency and stability. It required a $45 billion government bailout in 2008. The Financial Crisis Inquiry Commission, established by Congress to investigate the causes of the crisis, ultimately concluded that deregulation was among those causes, an institutional finding that carried weight precisely because it came from a body created by the same legislative branch that had passed the relevant laws. ^[9]

The intellectual case for banking deregulation rested on several interlocking beliefs, each of which seemed, at the time, to be supported by evidence. The most fundamental was that the American financial system had simply outgrown its Depression-era architecture. Policymakers and industry figures argued that a modern economy driven by capital markets, credit cards, ATMs, and electronic transfers had no use for the small, geographically confined banks that New Deal legislation had preserved. The transition to a capital markets-driven economy was taken as self-evident justification for consolidation, with the continued superiority of local banks in commercial lending to small businesses treated as a rounding error rather than a structural feature worth protecting. ^[1]

The geographic restrictions themselves had a history that made their eventual dismantling seem like simple rationality. The 1927 McFadden Act had codified state control over national bank branching, and by 1975, twelve states banned branching entirely while no state permitted out-of-state acquisitions. ^[4] The Douglas Amendment to the 1956 Bank Holding Company Act had further barred interstate acquisitions unless states explicitly reciprocated, effectively freezing the map of American banking for decades. ^[4] The original justifications for these limits, preventing bankers from choosing inaccessible locations to deter note redemptions and avoiding dangerous concentrations of financial power, had a certain 19th-century logic. But economists like Charles Calomiris had shown that the restrictions also produced small, undiversified banks that were acutely vulnerable to local economic shocks, and that geographic limits acted as a ceiling on well-managed institutions, retarding the natural process by which efficient firms displace inefficient ones and passing the costs directly to borrowers. ^[4] This research gave deregulators a genuine empirical foundation, even if they later extended its conclusions further than the evidence warranted.

The case against Glass-Steagall, the 1933 law separating commercial banking from securities underwriting, was built on similarly credible-seeming scholarship. Economists Randall Kroszner and Raghuram Rajan argued in a 1994 paper that pre-Glass-Steagall banks had actually avoided underwriting questionable securities because market participants were aware of the conflicts of interest and priced them accordingly, suggesting that the market, not regulation, had been doing the disciplinary work all along. ^[6] Economist George Benston concluded in the same year that all-in-one banking offered substantial benefits and few costs, and that fears of crowding out or systemic collapse were not supported by the historical record. ^[6] The Federal Reserve pointed to the performance of its own Section 20 affiliates, which had engaged in securities activities through the 1990s without any apparent spillover to parent banks, as evidence that the risks were manageable. ^[8] The belief that self-interest generates private market regulation completed the architecture: if firms would police their own risk-taking, government intervention was not merely unnecessary but actively harmful. ^[2]

There was also a quieter, more retrospective argument that proved influential. The New Deal regulatory framework, including deposit interest rate controls, had presided over decades of banking stability with few major failures, and this quiet period was widely attributed to the regulations themselves. The logic seemed airtight: regulation produced stability, therefore regulation was the cause of stability. A significant body of analysis now challenges this reading, arguing that the stable decades reflected benign macroeconomic conditions and unusually low interest rate volatility rather than the specific architecture of New Deal rules, and that the system's fragility only became visible when inflation and rate volatility returned in the 1970s. ^[9] But that revisionist account came later. In the 1980s and 1990s, the quiet period was treated as proof that the old rules had worked, and therefore that the new rules, which were more permissive, would work even better.

The deregulatory assumption moved through American political life along several reinforcing channels. The banking lobby's alignment with Reagan-Bush anti-government politics gave it ideological momentum that transcended any particular piece of legislation. Bankers who had been squeezed by the interest rate volatility of the late 1970s and early 1980s were receptive to arguments that New Deal-era restrictions were the source of their difficulties, and the Reagan administration's broader hostility to regulation provided a political environment in which those arguments flourished. ^[1][5] The $2.7 billion in lobbying expenditures that the financial sector directed at Congress in the decade before 2008 translated this ideological alignment into specific legislative outcomes, with campaign contributions reinforcing the message that deregulation was both economically sound and politically rewarding. ^[2][5]

Regulatory agencies absorbed the assumption as professional doctrine. The Federal Reserve's deregulatory mindset was not merely a reflection of Greenspan's personal views but a pervasive institutional orientation that shaped how staff economists framed questions, which research got published in Federal Reserve publications, and which regulatory actions were treated as appropriate. ^[2][5][6] Federal Reserve publications spread the view that Gramm-Leach-Bliley would deliver better service and lower prices through competition, presenting the consolidation thesis as an empirical prediction rather than an ideological preference. ^[6] Congressional testimony by the Fed chairman reinforced this framing, urging lawmakers to focus on economic growth and stability as the expected outcomes of deregulation and treating skeptics as defenders of an outdated and inefficient status quo. ^[8]

After the 2008 crisis, the assumption propagated in a different direction, through a secondary wave of commentary that accepted the deregulatory critique while misidentifying its mechanisms. Journalists, bloggers, and popular authors spread the argument that Gramm-Leach-Bliley and the Commodity Futures Modernization Act had directly enabled the subprime crisis by removing restrictions on bank securities activities and derivatives. ^[9] Academic commentators argued that these laws had tied regulators' hands. A significant body of legal and economic scholarship now challenges this specific account, arguing that the permissions granted by these laws largely codified practices that were already occurring under existing regulatory interpretations, and that the crisis's roots lay in supervisory failures and macroeconomic conditions rather than in the specific statutory changes. ^[9] The debate over which version of the deregulatory critique is correct has not resolved the underlying question of whether the consolidation thesis was sound.

The legislative dismantling of Depression-era banking restrictions proceeded in stages across two decades. In the early 1980s, policymakers enacted a series of deregulatory measures designed to encourage bank failures and mergers as a mechanism for consolidating the sector, operating on the premise that a leaner, larger banking system would be better suited to a modern economy. ^[1] The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 removed the remaining barriers to interstate banking and branching that the McFadden Act and the Douglas Amendment had maintained for decades, allowing banks to acquire institutions across state lines and operate unified branch networks nationally. ^[4][5] This was the legislation that made the consolidation wave structurally possible, and it was justified explicitly on the grounds that geographic restrictions had kept banks small, undiversified, and inefficient.

The Gramm-Leach-Bliley Act of 1999, effective March 2000, completed the project by repealing the Glass-Steagall provisions that had separated commercial banking from securities underwriting and insurance since 1933. ^[6] The legislation had been building for years: H.R. 10, introduced in 1997, had proposed permitting affiliations between banks and securities firms and between banks and insurance companies, and Greenspan had testified before Congress in its favor, framing the reform as a straightforward modernization that would allow American banks to compete with European and Asian universal banks. ^[8] The final law passed with broad bipartisan support, reflecting how thoroughly the modernization argument had penetrated both parties. By 2016, both major parties' platforms called for reinstating Glass-Steagall, a reversal that illustrated how completely the political valence of the issue had shifted in the intervening years, though the reinstatement did not occur. ^[9]

The Federal Reserve's decision not to exercise its authority under the Home Ownership and Equity Protection Act of 1994 to regulate predatory mortgage lending was a policy choice of a different kind: a deliberate non-action that left the subprime origination market without meaningful federal oversight during the years when it expanded most rapidly. ^[2] The Fed had the statutory authority to set minimum standards for mortgage lending practices regardless of the lender's charter, but declined to use it, consistent with the broader institutional view that market discipline would constrain excesses that regulation would only distort. The Commodity Futures Modernization Act of 2000 clarified that over-the-counter derivatives, including the credit default swaps that would later transmit losses across the financial system, were not subject to regulation as securities or futures contracts, resolving a jurisdictional ambiguity that Brooksley Born had sought to use as a basis for oversight. ^[9]

The assumption's credibility did not collapse at a single moment; it eroded through a series of events that each added weight to the skeptical case without, in the view of many economists, definitively settling it. The 2007-2008 financial crisis was the central event. The crisis itself broke the political consensus that had sustained deregulation, producing the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which reimposed significant regulatory requirements on large financial institutions, created the Consumer Financial Protection Bureau to oversee mortgage and consumer lending, and established new oversight mechanisms for derivatives markets. ^[2] The Financial Crisis Inquiry Commission, established by Congress and composed of members appointed by both parties, published its report in 2011 concluding that deregulation was among the causes of the crisis, a finding that carried institutional authority even as its specific causal claims remained contested among economists. ^[9]

The scholarly challenge to the deregulatory narrative took a different form. A significant body of legal and economic analysis, including work published in the Virginia Law Review, argued that the standard post-crisis account had misidentified the mechanisms. Gramm-Leach-Bliley and the Commodity Futures Modernization Act, this analysis contended, had not actually removed restrictions that were preventing subprime practices; the permissions they granted had largely pre-existed in regulatory interpretations, and the crisis's origins lay in supervisory failures, Federal Reserve interest rate policy, and the macroeconomic conditions that had inflated the housing market. ^[9] This argument did not rehabilitate the deregulatory consensus; it complicated the critique, suggesting that the problem was not primarily the specific statutes that had been passed but the broader regulatory philosophy that had governed their administration. The quiet period of banking stability that had seemed to validate New Deal regulation, this analysis suggested, had ended not because deregulation began but because the low interest rate volatility that had made the system stable gave way to the inflation of the 1970s. ^[9]

By 2016, the political reversal was complete enough that both major party platforms called for reinstating Glass-Steagall, a position that would have been considered fringe economics twenty years earlier. ^[9] The reinstatement did not happen, and the debate over what specifically went wrong and what specifically should be done about it has not produced a stable new consensus. Growing questions surround the consolidation thesis in its strongest form, the claim that fewer, larger banks would produce a more efficient and stable financial system, but the efficiency gains from branching deregulation documented in the empirical literature have not been erased from the record. What the crisis demonstrated, at minimum, was that the assumption's proponents had been wrong about the risks, and that the institutions whose growth they had facilitated were not, in the event, capable of policing themselves. ^[2][4][5]
