Countries sought to improve the sustainability and transparency of the global financial system in response to crises in the 1980s and 1990s. The Basel Committee on Banking Supervision was formed in 1974 by the G-10 members' central bank governors to facilitate cooperation on the supervision and regulation of banking practices. It is headquartered at the Bank for International Settlements in Basel, Switzerland. The committee has held several rounds of deliberation known collectively as the Basel Accords. The first of these accords, known as Basel I, took place in 1988 and emphasized credit risk and the assessment of different asset classes. Basel I was motivated by concerns over whether large multinational banks were appropriately regulated, stemming from observations during the 1980s Latin American debt crisis. Following Basel I, the committee published recommendations on new capital requirements for banks, which the G-10 nations implemented four years later. In 1999, the G-10 established the Financial Stability Forum (reconstituted by the G-20 in 2009 as the Financial Stability Board) to facilitate cooperation among regulatory agencies and promote stability in the global financial system. The Forum was charged with developing and codifying twelve international standards and implementation thereof. The Basel II accord was set in 2004 and again emphasized capital requirements as a safeguard against systemic risk as well as the need for global consistency in banking regulations so as not to competitively disadvantage banks operating internationally. It was motivated by what were seen as inadequacies of the first accord such as insufficient public disclosure of banks' risk profiles and oversight by regulatory bodies. Members were slow to implement it, with major efforts by the European Union and United States taking place as late as 2007 and 2008. In 2010, the Basel Committee revised the capital requirements in a set of enhancements to Basel II known as Basel III, which centered on a leverage ratio requirement aimed at restricting excessive leveraging by banks. In addition to strengthening the ratio, Basel III modified the formulas used to weight risk and compute the capital thresholds necessary to mitigate the risks of bank holdings, concluding the capital threshold should be set at 7% of the value of a bank's risk-weighted assets.
