Which Russian financial event in August 1998 caused a major emerging-market stock sell-off?

The Russian government default in August 1998 caused a major emerging-market stock sell-off.

Russia announced a devaluation of the ruble and a restructuring of domestic debt on August 17, 1998. The announcement came after years of fiscal pressure, weak tax collection, falling commodity prices, and heavy reliance on short-term government borrowing.

The crisis spread through international markets because investors reassessed risk in emerging economies and institutions exposed to Russian debt. The turmoil also contributed to the near-collapse of Long-Term Capital Management, a highly leveraged U.S. hedge fund. The Federal Reserve Bank of New York helped arrange a private-sector rescue rather than a direct government bailout.

The Russian event is sometimes described simply as the 1998 Russian financial crisis. Its central sovereign-debt event was not a conventional stock-exchange crash alone; it combined default, currency devaluation, banking stress, and market contagion.
