Summary

Sri Lanka's 2022 default was the first in the country's history. A combination of tax cuts depleting revenue, COVID destroying tourism earnings, ill-timed organic farming policy damaging food production, and unsustainable debt service created a perfect storm.

Mechanism of failure

Import-dependent economy with tourism as main FX earner → COVID → FX collapse → import restrictions → supply shortages → economic collapse → social unrest → political collapse.

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

Import cover below 3 months is a standard IMF warning threshold. Sri Lanka's fell below this in Q3 2021 — 6 months before default. Completely public data.

Key lessons for risk assessment

1.Import cover below 3 months is an unambiguous COLLAPSE signal for import-dependent economies

2.Simultaneous tax cuts and external shocks create fiscal collapse faster than any single factor

⚠ Which country today looks most like Sri Lanka at T-90?

🇷🇸

Serbia

SIGMA 52.0/100 — ACCUMULATION

Serbia has external financing needs and limited FX buffer. Not at Sri Lanka levels, but the import cover trajectory warrants monitoring.
