Which Russian default in August 1998 intensified the global market turmoil and helped bring down Long-Term Capital Management?

The Russian government debt default in August 1998 intensified global market turmoil and helped bring down Long-Term Capital Management.

On August 17, 1998, Russia restructured domestic ruble-denominated debt, widened the ruble’s trading band, and announced a temporary moratorium on some foreign debt payments. The announcement shattered expectations that Russian government obligations were nearly risk-free.

Investors responded by selling risky assets and seeking safer instruments. Credit spreads widened, liquidity deteriorated, and highly leveraged trading strategies suffered. Long-Term Capital Management, a prominent U.S. hedge fund, had large positions designed to profit from small differences between related securities. The sudden market dislocation produced losses that threatened broader financial instability.

The Federal Reserve Bank of New York coordinated a private-sector rescue in September 1998, but the U.S. government did not directly bail out the fund. Russia’s crisis also reflected falling oil prices, fiscal weakness, and political uncertainty, not merely one isolated bond event.
