The right of governments to employ capital controls has always been the official orthodoxy of the International Monetary Fund, and the organization's formal rules providing this right have not changed significantly since the IMF was founded in 1945. But informally, among the staff inside the IMF, these controls became heresy in the 1980s and 1990s, prompting critics to accuse the IMF of indiscriminately encouraging the liberalization of controls and precipitating a wave of financial crises in emerging markets in the late 1990s.
