The regulation of finance is central to the growth and development of every economy. Financial regulation determines the overall character of the financial system, the relationship between borrowers and savers, the allocation of capital, and the macroeconomic performance of the economy. Financial market regulation is distinct from regulation of other sectors of the economy because of the essential infrastructural role of finance—all other sectors of advanced economies depend on the financial system. Despite its enormous importance, financial regulation normally has low political salience. Except in times of crisis, most voters—and therefore politicians—have relatively little interest in the matter. This can be attributed in part to the complex and technical nature of financial markets and regulation, which relatively few people understand well. Low political salience facilitates a regulatory process that is very heavily shaped by regulators (technocrats) and the industry they regulate, with only minor direction from elected political leaders. In the long history of capitalism, bank and financial system crises have been regular occurrences. Regulation, or regulatory failure, is often seen as a cause of crises, but regulatory change is also the response. Thus any given financial regulatory regime is never settled for long. After the Great Depression, advanced capitalist economies introduced highly restrictive financial regulatory regimes designed to minimize systemic risk from bank failures. In the postwar period, restrictive regulatory regimes were combined with capital controls that limited international movements of capital. The postwar Bretton Woods international monetary regime stabilized fixed exchange rates through such controls and, when necessary, lending by the International Monetary Fund (IMF) to countries that could not pay for their external debts. Starting with the collapse of the Bretton Woods regime in the early 1970s, all the advanced economies started liberalizing financial market regulation and removing capital controls as part of a broader shift toward a neoliberal economic philosophy. These deregulatory measures brought about a dramatic transformation of domestic financial systems and the reemergence of a dynamic and rapidly growing international financial market. Such dynamic and internationalized financial market was, in large part, the root cause of the early-21st-century financial crisis. The Great Financial Crisis of 2008 precipitated widespread review and revision of financial market regulations at both the domestic and international levels. These revisions include a shift from private self-regulation to state-driven regulation of financial markets, the centralization of regulation at the level of the European Union, and a closer cooperation between states in forging international regulatory standards. Nonetheless, despite the dramatic growth of the international financial market and transnational efforts to coordinate regulation, financial regulation remains overwhelmingly a domestic affair.
