Wars tend to leave a sharp, visible mark on a country's economy. Lining up several conflicts by the year fighting began shows a common pattern: national output (GDP) often contracts hard in the onset year — by a quarter or more in several cases here — before recoveries that vary widely in speed and strength. This page compares those patterns using free, official World Bank annual data. It is a historical comparison, not a forecast, and it never claims a conflict was the sole cause of any movement.
- Cases lined up by conflict-onset year reveal a shared deep-contraction pattern around year 0.
- Recovery paths differ: some rebound fast, others stay depressed for years.
- GDP growth, GDP per capita and inflation are shown per case, source-reported and dated.

The shared pattern: GDP growth around conflict onset
Each line is a country's annual GDP growth, lined up so year 0 is the documented onset of large-scale conflict. The deep dip around year 0 is the common thread; what happens afterwards is not.
Explore each case
Pick a conflict to see its full GDP-growth history with the onset year marked, plus the average growth in the three years before, the onset year itself, and the three years after.
Ukraine — Russia's full-scale invasion (2022).
Before/during/after are simple averages of the World Bank annual series around 2022; the dashed line marks the onset year for reference only. Gaps mean the World Bank did not report a value that year.
How to read this — and what it does not prove
- Association, not causation: output moves for many reasons; the onset marker is a reference line, never a claim the conflict was the sole cause.
- Gaps are real: some countries (e.g. Syria) stop being reported once conflict deepens. Missing years are shown as gaps, never filled with guesses.
- Different conflicts, different shapes: a single "war effect" on GDP does not exist — magnitude and recovery vary widely.
- Not a forecast: nothing here predicts any future economy. It is a historical comparison only.
Source & method
Annual series are machine-read from the free, key-free World BankAPI (World Development Indicators) by an on-demand ingest command, then committed as a static snapshot — no API keys, no paid APIs, nothing invented. Before/during/after figures are simple averages of the World Bank annual series around each conflict's documented onset year. Values are source-reported World Bank annual indicators. The reference year marks the documented onset of large-scale conflict and is a chart marker only — many factors move GDP, inflation and incomes, and nothing here attributes a movement to any single event. Some countries (e.g. Syria) stop being reported after conflict begins; gaps are shown as gaps, never filled. Not a forecast, not investment advice.
