Lecture summary: This lecture considers what Josef Kunz termed “swings of the pendulum” in international monetary and financial law and the formal and informal institutions in these related fields. International monetary law exploded in importance after the Second World War with the creation of the International Monetary Fund (IMF) and a global system of managed exchange rates. With the collapse of the Bretton Woods system in 1971 and a decline in capital controls, the IMF evolved from a dominant institution into a peer of central banks and private markets, providing surveillance of the “non-system” of floating exchange rates and assisting in responses to financial crises.

By contrast, international financial law, which was of limited importance during the Bretton Woods era, has become a major soft law force in the global financial sector since the Basel Committee on Banking Supervision was created in 1974. The dichotomy between profit maximization and systemic risk at the core of global finance today is overseen and guided by the technocrats of the Basel Committee, the Financial Stability Board and other institutions of international financial law.

Today, the pendulums of international monetary and financial law may be reversing again. Armed conflict, rising authoritarianism, growing fragmentation of the global financial system, and a revival of capital controls and other restrictions on capital flows could reinvigorate international monetary law and the IMF. This institution has reimagined itself multiple times already while staying true to its original mandate of safeguarding monetary stability.
