The Russian financial crisis (also called Ruble crisis or the Russian Flu) hit Russia on 17 August 1998. It resulted in the Russian government and the Russian Central Bank devaluing the ruble and defaulting on its debt. The crisis had severe impacts on the economies of many neighboring countries. Meanwhile, James Cook, the senior vice president of The U.S. Russia Investment Fund, suggested the crisis had the positive effect of teaching Russian banks to diversify their assets.
Declining productivity, a high fixed exchange rate between the ruble and foreign currencies to avoid public turmoil, and a chronic fiscal deficit were the reasons that led to the crisis. The economic cost of the first war in Chechnya, estimated at $5.5 billion (not including the rebuilding of the ruined Chechen economy), also contributed to the crisis. In the first half of 1997, the Russian economy showed some signs of improvement. However, soon after this, the problems began to gradually intensify.
Two external shocks, the Asian financial crisis that had begun in 1997 and the following declines in demand for (and thus price of) crude oil and nonferrous metals, severely impacted Russian foreign exchange reserves.
A political crisis came to a head in March when Russian president Boris Yeltsin suddenly dismissed Prime Minister Viktor Chernomyrdin and his entire cabinet on 23 March 1998. Yeltsin named Energy Minister Sergei Kiriyenko, then 35 years old, as acting prime minister.
