Summary

Russia's 1998 default triggered a global contagion including the LTCM collapse. The crisis was caused by commodity dependence on oil (prices at 12-year lows), a short-term debt trap in GKO bills, and an indefensible currency peg.

Mechanism of failure

Commodity revenue collapse → fiscal gap → debt rollover at 100%+ yields → impossible debt service → peg defense exhausts reserves → default and devaluation.

What the early warning missed — and what SIGMA would have caught

GKO yields above 50% signaled market-implied default probability above 40% in June 1998 — two months before the actual default. This was publicly visible.

Key lessons for risk assessment

1.Short-term debt yields above 50% imply market-assigned default probability above 35% — no exception in history

2.Commodity-dependent sovereigns in commodity downturns have 3-6 month fiscal buffers before crisis

3.Currency peg defenses with declining reserves always fail — the question is timing, not outcome
