REGULATING BANK MERGERS: PAST AND PRESENT

For the first time in decades, bank merger policy stands at a crossroads. Amidst a new and wide-ranging antimonopoly movement, concerns regarding concentrated financial power and the structure of the American banking system have taken center stage. Following calls for public comthe Department of Justice, internal discord over reform efforts at the Fedregional banks, a fundamental reassessment of the law governing bank mergers and acquisitions is firmly underway. While some policy-makers and scholars have argued that antitrust law should play a larger role in preventing consolidation in the financial sector, this Article employs the methodology of legal history to emphasize the limits of reviving antitrust in banking. Excavating the origins and evolution of the Bank Holding Company Act (the "BHCA') and the Bank Merger Act (the "BMA'), which govern regulatory oversight of bank mergers, reveals that an expansive conception of the public interest extending well beyond the bounds of antitrust doctrine guided the bank merger regime in its formative early years. By retracing the legislative, administrative, and judicial interpretations of the public interest approach to bank mergers, this Article foregrounds an alternative, and historically potent, mechanism through which to combat banking consolidation. Ultimately, the complex history of the BHCA and BMA provides an important reminder that while antitrust has long served as a critical weapon in the battle against concentrated economic power, it has not been the only weapon. As the future of bank merger policy hangs in the balance, a turn to the past may therefore yield a more promising way forward.
