Key Points
- Economies lose about 7% of output over five years
- Damage often lasts more than a decade
- Military spending surges worsen inflation and debt
- Spillovers hit neighbouring and trading economies
ISLAMABAD: The International Monetary Fund has warned in its analytical research that wars inflict large and persistent economic losses, with damage lasting for years.
According to the IMF, the impact of war on economies often exceeds that caused by financial crises or natural disasters.
The findings come from analytical chapters of the IMF’s upcoming World Economic Outlook.
In the study, the Fund examined wartime economic trends across decades of global data.
The research underscores that conflicts are not short-term shocks but long-lasting disruptions that fundamentally weaken growth trajectories.
Economies directly affected by conflict typically face a sharp contraction at the onset of war, followed by cumulative output losses of around 7 per cent over five years.
More significantly, these losses persist well beyond the end of hostilities, often extending for more than a decade.
The Fund emphasised that the persistence of these losses distinguishes conflicts from other economic shocks.
Output losses from wars persist even after a decade and generally exceed those associated with severe financial crises or natural disasters, highlighting the structural damage caused by prolonged instability.
The IMF’s research points to several channels through which conflicts erode economic capacity.
Physical destruction of infrastructure, disruption of production, and displacement of labour all contribute to an immediate contraction in output.
Over time, these effects are compounded by weakened institutions, reduced productivity, and a collapse in private investment.
Beyond domestic impacts, the IMF highlighted significant spillover effects. Neighbouring countries and key trading partners also experience economic shocks through disrupted trade, financial volatility, and heightened uncertainty.
Even countries not directly involved in conflict can experience slower growth and rising inflation due to these transmission channels.
A major concern identified in the IMF analysis is the surge in military spending during periods of conflict. The Fund found that defence buildups have become more frequent globally, particularly in emerging and developing economies, with spending increases often financed through higher fiscal deficits.
On average, fiscal deficits widen by about 2.6 percentage points of GDP, and public debt rises by roughly 7 percentage points within three years of increased military expenditure.
Although such spending can provide a short-term economic stimulus, the IMF cautioned that it often fuels inflation and creates medium-term fiscal vulnerabilities.
The research also highlights a broader global trend: conflicts are increasing in frequency and scale. The IMF noted that more than 35 countries were experiencing conflict in recent years, affecting nearly half of the world’s population.
This escalation is contributing to increased military spending worldwide, further straining public finances and complicating macroeconomic management.
Another critical issue is the fragility of peace. Around 40 per cent of countries relapse into conflict within five years, undermining recovery efforts and prolonging economic damage.
This cycle of instability makes it difficult for economies to rebuild, attract investment, and restore sustainable growth.
The Fund stressed that early policy action is essential to mitigate long-term damage. Measures such as economic stabilisation, debt restructuring, and sustained international support can help lay the foundation for recovery.
However, the effectiveness of these interventions depends heavily on the durability of peace and the strength of domestic institutions.
The IMF’s findings come at a time of heightened geopolitical tensions, reinforcing concerns that conflicts are becoming a major structural risk to the global economy, with far-reaching consequences for growth, inflation, and financial stability.
