Summary

The Tequila Crisis demonstrated that even investment-grade emerging markets can collapse rapidly when short-term external debt maturities create a rollover trap. The shock was amplified by political assassinations reducing investor confidence.

Mechanism of failure

Current account deficit financed by short-term USD-linked bonds (Tesobonos) → US rate hikes drain EM capital → FX reserves deplete → rollover impossible → devaluation and collapse.

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

Mexico's FX reserves fell from $29B to $6B in 1994 while the central bank secretly intervened to maintain the peg. This reserve depletion was partially hidden from markets.

Key lessons for risk assessment
1.Short-term foreign-currency-linked sovereign debt creates a maturity trap that forces devaluation when rollover fails
2.Central bank reserve depletion in defense of currency pegs always fails — the only question is timing
3.Political risk events (assassinations, uprisings) accelerate but do not cause crises — underlying vulnerabilities must exist first
⚠ Which country today looks most like Mexico at T-90?

Romania
SIGMA 56.5/100 — ACCUMULATION

Romania's external financing dependency and current account deficit create structural similarities to Mexico 1993-1994.
