The Central Bank Governors' Symposium 2002 examined the architecture of the world's financial system. Horst Koehler, Managing Director of the IMF, and the Bank of England's two Deputy Governors at the time, David Clementi and Mervyn King, gave the main addresses. This article summarises what they said. It also gives a precis of eight background papers provided for the occasion. Taken together, these eleven contributions explore general aspects of the international financial architecture, as well as discussing how financial crises may be contained or prevented, and best resolved when they do occur.
