The world at the time.

The forecast was issued after the pandemic shock was already visible. The economy combined hydrocarbon exports with domestic nonhydrocarbon activity.

What happened.

The linked later IMF statistical vintage records -3.6% growth in 2020. The contraction direction was correct, but the point estimate differed by 0.7 percentage points.

The counter-signal.

The IMF's contemporary regional report warned that the depth and duration of the shock were highly uncertain. Fiscal and monetary support could cushion losses, while external demand remained unusually uncertain.

Verdict.

Reasoning: contested · Outcome: partial

The outcome receives a partial score because the recession direction survived while the numerical estimate missed. Model quality cannot be established from one forecast error, so no quadrant is assigned.

Numerical claim and later estimate verified. Forecast versus recorded historical estimate, not a final immutable statistic; GDP revisions can change the variance. Regional risks were explicit in April 2020; causation is interpretive.

Cause of death / explanatory lens.

No cause of death assigned

The lesson.

How should a point forecast communicate the range of losses when both the pandemic and policy response remain unsettled?
