Which 1998 sovereign default and currency devaluation triggered a major global market shock?

The Russian financial crisis was the 1998 sovereign default and currency devaluation that triggered a major global market shock.

Russia devalued the ruble and defaulted on some domestic debt on August 17, 1998. The government had struggled with weak tax collection, falling commodity revenues, political instability, and a heavy debt burden. Pressure on the ruble intensified after the Asian financial crisis weakened investor confidence in emerging markets.

The crisis spread through financial markets because investors reduced exposure to risky assets worldwide. The collapse of Long-Term Capital Management, a highly leveraged U.S. hedge fund, became an especially important connected event. The Federal Reserve helped coordinate a private-sector rescue, although the Russian crisis was not the sole cause of the fund's difficulties.

The Russian event is often confused with the Asian financial crisis because they occurred only a year apart and were linked through investor sentiment. They were distinct crises: the Asian episode began with Thailand's currency problems, while the Russian episode centered on sovereign debt, the ruble, and public finances.
