ON THE morning of August 17th most of India’s economic policymakers gathered in the prime minister’s house in Delhi. They were there to launch an official economic history of 1981-97, a period which included the balance-of-payments crisis of 1991. The mood was tense. India, said Manmohan Singh, the prime minister, faced “very difficult circumstances”. “Does history repeat itself?” asked Duvvuri Subbarao, the outgoing head of the Reserve Bank of India (RBI). “As if we learn nothing from one crisis to another?” ___________ This is not a repeat of 1991. When India last had a crisis Boris Yeltsin was about to stand on a tank in Moscow and Nirvana was hitting the big time. Things have changed in financial terms , too. Back then India had a fixed exchange rate, which the state almost bankrupted itself trying to defend—it had to fly gold to the Bank of England in return for a loan. Today India has a floating exchange rate and a government with almost no foreign-currency debt.
