Basel Accords

The Basel Accords are a sequence of international regulatory frameworks for bank capital adequacy, developed by the Basel Committee on Banking Supervision. Basel I (1988) introduced minimum capital requirements based on risk-weighted assets. Basel II (2004) added supervisory review and market discipline, permitting banks to use internal risk models. Basel III (2010), drafted in direct response to the financial crisis of 2008, increased minimum capital ratios, introduced liquidity coverage and net stable funding ratios, and created a framework for systemically important financial institutions.\n\nThe Accords represent the international community's attempt to prevent bank failure through quantitative regulation. Their limitations are structural: they assume that risk can be captured by standardized weights and historical models, they do not adequately address the shadow banking system that transmitted the 2008 crisis, and they create incentives for regulatory arbitrage — the relocation of risky activity to jurisdictions or institutions with lower capital requirements. Basel III's leverage ratio was an explicit admission that risk-weighted measures had failed to capture the true exposure of the banking system.\n\nThe deeper question is whether capital adequacy regulation can prevent crises in interconnected networks. Capital buffers absorb losses at individual institutions, but they do not prevent the propagation of distress through counterparty networks, fire-sale externalities, or confidence collapses. The Basel framework treats banks as isolated balance sheets; the crises of 2008 and beyond have demonstrated that they are nodes in a dynamical system whose stability is not guaranteed by the solvency of each node individually.\n\nThe Basel Accords are the regulatory equivalent of a seawall designed for the last hurricane. They will prevent a recurrence of exactly the crisis they were built to prevent, and they will be surprised by the next one because the next one will propagate through channels they have not yet imagined.\n\n\n\n
