The document discusses India's exchange rate policies and crises since independence in 1947. It summarizes that India faced major financial crises and rupee devaluations in 1966 and 1991. In 1966, a war with Pakistan, drought, and reduced foreign aid necessitated devaluation despite trade restrictions. In 1991, high inflation, inconsistent trade deficits, and inadequate export incentives caused a crisis that led to economic liberalization. Foreign exchange reserves grew steadily from 2006-2012 except for a decline in 2008-2009 during the global financial crisis.
