The war in West Asia is no longer just a geopolitical flashpoint, it is fast becoming a global economic stress test. As the United States and Israel’s conflict with Iran stretches on, the International Monetary Fund on Monday issued a stark warning: the shock is global, but its consequences will be uneven, and in many cases, severe.
At the heart of the concern is timing. The global economy had only just begun stabilising after a series of shocks, from the pandemic to inflationary spikes and tightening financial conditions. Now, a fresh disruption threatens to undo that fragile recovery.
“It is also dimming the outlook for many economies that had only just shown signs of a sustained recovery,” the IMF noted in a blog analysis authored by its economists,
including Tobias Adrian and Jihad Azour.
The Fund’s central warning was blunt and sweeping: “Although the war could shape the global economy in different ways, all roads lead to higher prices and slower growth.”
Why The IMF Called This A ‘Global But Uneven’ Shock
The IMF described the current crisis as a “global, but asymmetric” shock, one that affects nearly all economies, but not equally.
While advanced economies and commodity exporters may have buffers to absorb higher costs, the pressure is disproportionately falling on poorer nations, energy importers, and countries with limited fiscal space. This imbalance, the Fund said, is the defining feature of the current crisis.
Energy-importing economies across Asia and Europe are already bearing the brunt of rising fuel and input costs. At the same time, several countries in Africa and Asia are struggling not just with higher prices, but with access itself, finding it difficult to secure essential supplies even at inflated rates.
This divergence is widening existing fault lines in the global economy, pushing vulnerable countries closer to crisis even as others manage to absorb the shock.
Strait Of Hormuz Disruption Puts Energy Markets Under Strain
The epicentre of the disruption lies in the Strait of Hormuz, a narrow but critical maritime corridor through which a significant share of global energy flows. Roughly 25 to 30 per cent of the world’s oil and about 20 per cent of liquefied natural gas pass through this route, making it one of the most strategically important chokepoints in global trade.
Iran’s closure of the strait, combined with damage to regional infrastructure, has triggered what the International Energy Agency (IEA) describes as one of the most severe disruptions in oil market history.
The impact on prices has been immediate. The global benchmark Brent crude oil price briefly hit $119 per barrel on Tuesday, close to its highest level since the start of the US-Israel war with Iran, before easing to around $104–$105 on Wednesday amid continued volatility and supply concerns.
In response, the IEA’s 32 member countries earlier this month agreed to release a record 400 million barrels of oil from strategic reserves to stabilise markets. Finance leaders from the Group of Seven economic powers said they were ready to take “all necessary measures” to safeguard energy market stability and limit broader economic spillovers.
Yet, the IMF cautioned that such interventions may only soften, not eliminate, the impact if the disruption persists.
How The Crisis Is Spilling From Oil Into Food Prices
What began as an energy shock is now rapidly spilling into food and agriculture, an escalation that carries far more immediate consequences for vulnerable populations.
Higher fuel costs are pushing up transportation and production expenses, while disruptions to fertiliser supplies from the Gulf are increasing agricultural input prices at a critical stage in the planting cycle.
The IMF warned that this combination could weaken harvests and sustain food inflation across regions, including the Middle East, Africa, Asia-Pacific, and Latin America.
“That makes any spike in fertiliser and food prices not just an economic problem but a socio-political one,” the Fund said.
The implications go beyond economics. Rising food prices have historically been linked to social unrest, particularly in regions where household spending is heavily concentrated on basic consumption.
Why Low-Income Countries Face The Sharpest Impact
Low-income countries are emerging as the most vulnerable group in this crisis.
The IMF highlighted that food accounted for around 36 per cent of household consumption in poorer nations, significantly higher than about 20 per cent in emerging markets and just 9 per cent in advanced economies. This structural difference means even modest price increases can have disproportionately severe effects.
As food and fertiliser costs rise, these economies face a growing risk of food insecurity, social instability, and fiscal stress, especially at a time when international aid flows are declining and financial conditions are tightening.
The IMF warned that some countries may require additional external support, even as advanced economies scale back assistance.
Higher Prices, Slower Growth: The Core IMF Warning
At a macroeconomic level, the IMF sees the conflict reviving a familiar and difficult pattern: rising inflation coupled with slowing growth.
Sustained increases in energy and food prices are likely to push inflation higher across regions, even as economic activity weakens. Historically, oil price shocks have tended to produce exactly this combination—higher prices and lower growth.
The concern is not just immediate inflation, but expectations. If households and businesses begin to anticipate persistently higher prices, it could trigger wage and price spirals that are harder to control.
Such dynamics would force central banks into a difficult position, tightening policy further to contain inflation, at the risk of deepening economic slowdowns.
Tighter Financial Conditions Add To Global Pressure
Beyond commodities, the shock is already feeding into global financial markets.
The IMF identified three main transmission channels: energy prices, supply chains, and financial conditions. Together, they are contributing to tighter credit environments, increased volatility, and weaker growth prospects—even in countries not directly involved in the conflict.
Large energy importers in Asia and Europe are particularly exposed, facing rising input costs alongside weakening demand and tightening liquidity.
Why The War’s Duration Will Be Critical
Perhaps the most critical variable shaping the economic outlook is the duration and trajectory of the conflict.
The IMF makes it clear that the scale of damage will depend on how long the war lasts, how far it spreads, and how deeply it disrupts infrastructure and supply chains.
A short-lived conflict could limit the fallout. But a prolonged or expanding war risks entrenching high energy costs, prolonging inflation, and sustaining geopolitical uncertainty.
The Fund suggested that a middle-ground scenario—where tensions persist without full escalation—may be the most likely. In such a case, economies would face a prolonged period of elevated prices, stubborn inflation, and slower growth.
What Happens Next?
The IMF is expected to present a more comprehensive assessment in its upcoming World Economic Outlook, to be released on April 14 during the IMF-World Bank Spring Meetings in Washington.
For now, its message is clear: even if the conflict remains geographically contained, its economic consequences are neither limited nor evenly distributed.
From energy markets to food systems, the ripple effects are already visible, and for many of the world’s most vulnerable economies, the worst may still lie ahead.
