Russian Ruble Crisis and Default — August 17, 1998
Sovereign default, LTCM contagion, and a rapid recovery
Russia defaulted on domestic debt and devalued the ruble on August 17, 1998. The crisis triggered contagion and nearly destroyed LTCM. The S&P 500 fell 19% from its July peak to the October 8 trough. The index posted a new all-time high by November 27 — full recovery in under four months.

What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
The crisis was a liquidity event, not a solvency event for the US
The US economy was growing at 4%+ GDP. Once the Fed cut rates three times in fall 1998, liquidity normalized and equities recovered.
LTCM amplified the shock far beyond Russia's economic weight
Russia's GDP was barely 1% of world output, yet LTCM held $125 billion on $4.7 billion of equity. The leverage ratio created systemic risk, not the sovereign default.
Contagion from EM crises is sharp but short-lived
Buying at the October 8 trough captured roughly +28% over the subsequent 12 months. Portfolio rebalancers who held through the panic were rewarded within a single quarter.
For your portfolio
Leverage, not the sovereign default itself, turned an economy of roughly 1% of world output into a US market event. When a foreign default hits the tape, consider asking where the leveraged holders sit — and whether any of your own positions depend on borrowed stability — rather than selling broad equity exposure that in 1998 recovered within a quarter.
