Key Details
The IMF working paper, Macroeconomics of War and Recovery, uses a new global dataset (including India) to compare economies before and after the onset and termination of conflicts. India is included in both the national and firm-level datasets, but the paper does not report separate estimates for India.
Indicator | Finding |
|---|---|
Global coverage | 194 countries, 1946–2024 |
Conflict events | 170 conflict onsets and 158 terminations |
Output at conflict onset | Falls by approximately 3% |
Output after five years | Cumulative loss of roughly 7% |
Longer-term loss | Approximately 11% after ten years in an extended analysis |
Inflation during major conflicts | Consumer prices reach about 35% above pre-war levels after five years |
Durable post-conflict peace | Output rises 3.8% over five years, recovering only about half the corresponding wartime loss |
Firm-level evidence | More than 5 million geocoded firms across 1983–2023 |
The firm-level analysis treats a business as directly exposed when a conflict occurred within 20 kilometres of its location. Approximately 3.4% of firms in the sample experienced such exposure.
War Causes Larger Losses Than Other Major Economic Shocks
Output falls by around 3% when conflict begins, with cumulative losses reaching about 7% after five years and, in an extended estimate, 11% after a decade.
Applying the same methodology to other shocks, the authors find that conflict generally causes larger output losses than banking, currency and sovereign-debt crises or severe natural disasters. Even lower-intensity conflicts generate short-term losses comparable with a currency crisis.
The severity also matters: major conflicts produce the largest losses, while conflicts within countries tend to leave more persistent economic damage than wars between states.
External Pressures Amplify the Economic Damage
Major conflicts sharply reduce investment and private consumption. Government consumption remains broadly stable, which the paper associates with spending being redirected towards defence.
The external sector creates a reinforcing chain of pressure: exports fall more than imports, foreign investment and portfolio flows decline, dependence on official assistance increases and capital controls tighten. Foreign-exchange reserves then fall, currencies depreciate and import scarcity adds to inflation.
Five years after conflict begins, consumer prices are estimated to be around 35% above their pre-war level, while the gap between parallel-market and official exchange rates almost doubles.
Economic Damage Spills Across Borders
Neighbouring countries and economies heavily dependent on a conflict country’s exports experience output losses of around 1% or less during the first two years of a major conflict.
These effects generally fade as trade is redirected and supply chains adjust. But they show that the economic costs of war extend beyond countries directly involved in the conflict.
Durable Peace Recovers Only Part of the Loss
The paper defines durable or “non-fragile” peace as conflict not resuming for at least five years. Under these conditions, output rises to about 3.8% above its end-of-conflict level after five years.
Even this sustained recovery restores only around half of the output lost during a comparable period of war. Where conflict resumes within five years, output fails to recover.
The asymmetry is important: economic destruction during war is faster and larger than reconstruction after peace.
Employment Recovers Faster Than Productive Capacity
Post-war recovery comes primarily through employment returning to civilian activity, while capital accumulation and productivity remain weak.
Firm-level evidence shows that exporters, capital-intensive firms and financially stronger companies achieve larger gains in employment and productivity. Labour-intensive firms and non-exporters recover mainly through employment, while financially weaker firms continue to face capital shortfalls.
Persistent uncertainty and financing constraints therefore appear to hold back investment even after fighting ends, allowing jobs to recover before productive capacity.
How Does the Paper Estimate the Economic Effect of War?
The authors use a local-projection difference-in-differences method, comparing economic changes after conflict begins or ends with countries unaffected by conflict during the surrounding period.
Countries that recently experienced conflict or are about to enter one are excluded from the comparison, creating a “clean control” group.
The results should therefore be read as average effects across historical conflict episodes, not forecasts of the economic cost of any particular future war.
Policy Relevance
For India, the paper’s most useful contribution is its treatment of conflict as a combined trade, financial and inflation shock, rather than solely a disruption to commodity supplies or government expenditure.
Stress tests need connected scenarios: A major external conflict can simultaneously weaken exports, raise import costs, trigger capital outflows, pressure the rupee and reduce reserve buffers. Assessing each channel separately may understate the combined effect.
Trade concentration shapes spillovers: Dependence on a conflict-affected supplier or market can transmit losses even when India is not a belligerent. Diversifying suppliers, transport routes and payment channels can reduce short-term exposure.
Reserve adequacy becomes more important during overlapping shocks: Foreign-exchange reserves may be required as export earnings and private financing weaken at the same time. The study shows why reserve management and capital-flow planning form part of conflict preparedness.
Reconstruction finance should reach viable but constrained firms: The post-conflict evidence indicates that financially strong and export-oriented businesses recover faster. Credit guarantees, risk-sharing instruments and functioning payment systems may be necessary to prevent temporary financing constraints from becoming permanent losses of productive capacity.
Peace and reconstruction must be planned together: Durable peace is the foundation of recovery, but restoring confidence, investment and access to finance determines how much lost output can actually be regained.
