Which Russian financial crisis event on August 17, 1998 intensified a worldwide emerging-market sell-off?

Russia’s debt default on August 17, 1998, intensified the worldwide emerging-market sell-off.

On that date, the Russian government devalued the ruble, declared a moratorium on some foreign debt payments, and effectively defaulted on domestic government debt. The announcement followed years of fiscal pressure, weak tax collection, falling commodity prices, and the financial shock spreading from the 1997 Asian crisis.

The crisis damaged confidence in emerging markets and contributed to severe losses at Long-Term Capital Management, a large US hedge fund. The Federal Reserve helped arrange a private-sector rescue in September 1998 because officials feared disorderly liquidation could destabilize financial markets.

The event is sometimes described simply as a ruble crisis, but the default was a central part of the episode. Russia later benefited from higher oil prices and economic reforms, while the ruble’s collapse initially caused major inflation and a banking crisis.
