August 17, 1998, marked the beginning of the 1998 Russian financial crisis, when Russia devalued the ruble and defaulted on domestic debt.
The Russian government widened the ruble’s trading band, announced a moratorium on some foreign debt payments, and restructured domestic ruble-denominated debt. The measures reflected pressure from falling oil prices, weak tax collection, large fiscal deficits, and declining investor confidence. Russia had struggled to maintain its exchange-rate policy while meeting its obligations.
The crisis spread through international markets. Investors became more cautious about emerging-market debt, and losses at the highly leveraged hedge fund Long-Term Capital Management threatened broader financial disruption. The Federal Reserve helped arrange a private-sector recapitalization of LTCM, although the U.S. government did not directly provide the fund’s rescue money.
The episode is often remembered as a sovereign default, but it also involved currency devaluation and banking stress. These separate elements interacted, making August 17 a crucial date in the late-1990s sequence of market shocks.
