The International Monetary Fund (IMF) has cut its 2026 global economic growth forecast to 3.1% and warned that if hostilities in the Middle East continue and energy infrastructure suffers severe damage, global growth could fall below 2%, approaching the recession threshold defined by the IMF.
On Tuesday, the IMF released its latest World Economic Outlook report, revising this year's global GDP growth forecast down by 0.2 percentage points from 3.3% in January to 3.1%. The report states that since the joint US-Israel military action against Iran began on February 28, the Strait of Hormuz has been substantially blockaded, causing oil prices to surge sharply and turning a previously upward-trending global growth outlook downward. Pierre-Olivier Gourinchas, the IMF Chief Economist, stated:
<blockquote>
&#34;The Middle East conflict has abruptly halted growth momentum. The ultimate scale of the shock will depend on the duration and intensity of the conflict, as well as the speed at which energy production and transport return to normal after hostilities cease.&#34;
</blockquote>
This downgrade has had a particularly significant impact on emerging markets. This year, the growth forecast for emerging economies was lowered from 4.2% to 3.9%, while the inflation forecast was raised by 0.7 percentage points to 5.5%. The IMF also warned that the war in the Middle East has increased uncertainty regarding the economic prospects of emerging markets, with risks leaning toward a deeper recession. The report was released in Washington during the Spring Meetings of the IMF and the World Bank, becoming a core topic for finance ministers and central bank governors attending the meetings.
<h2>Three Scenarios: From Mild Slowdown to Approaching Recession</h2>
Based on different potential outcomes of the US-Iran conflict, the IMF has established three scenario forecasts, showing significant differences in growth and inflation paths.
Under the baseline (reference) scenario, where the conflict is relatively short-lived, energy commodity prices are expected to rise by approximately 19% this year. Global growth would be 3.1%, with global inflation rising from 4.1% in 2025 to 4.4%, while growth remains stable at 3.2% in 2027.
If the blockade of the Strait of Hormuz extends and damage to drilling and refining facilities worsens, the IMF projects global growth will drop to 2.5%, with inflation rising to 5.4%.
In the most severe scenario, energy supply disruptions extend into next year, inflation expectations become significantly unanchored, financial conditions tighten substantially, and the average annual oil price reaches $110 per barrel. Under these conditions, global economic growth would fall below 2%—a level seen only four times since 1980, with the last two occurrences being the 2008 global financial crisis and the pandemic period. In this scenario, global inflation in 2026 would reach 5.8%, rising further to 6.1% in 2027.
<h2>Europe and Emerging Markets Hit Hardest First</h2>
The distribution of this shock across economies is uneven, with economies highly dependent on energy imports facing the heaviest pressure.
Among major developed economies, Europe has suffered the most pronounced impact. Germany's growth forecast for this year is only 0.8%, revised down by 0.3 percentage points from the January forecast; the UK also faces growth of just 0.8%, a decline of 0.5 percentage points. Due to its status as a net energy exporter, the US has been relatively less affected, with a growth forecast of 2.3% for this year, revised down slightly by 0.1 percentage point from January.
Emerging markets have faced even heavier blows. In the most severe scenario, the impact on emerging and developing economies is nearly twice that of developed economies. Growth in the Middle East and Central Asia is expected to slow dramatically from 3.6% in 2025 to 1.9%, with Bahrain, Iraq, Kuwait, and Qatar all facing economic contraction. Iran's economy has been hit the hardest, with GDP expected to contract by 6.1% in 2026, a sharp drop of 7.2 percentage points from the January forecast of 1.1% growth; the IMF expects Iran's output to recover by 3.2% in 2027.
Many economies heavily reliant on energy and chemical imports from the Gulf region, especially Asian emerging markets, have successively introduced intervention measures such as price controls and subsidies to cope with supply shortages. However, IMF economists have warned that such measures are often poorly designed and costly, potentially triggering rationing effects and spillovers to other countries. They recommend that countries adopt more precise and temporary support methods, prioritizing direct transfers to the most vulnerable households.
<h2>Inflation Resurgence Puts Central Banks in a Dilemma</h2>
While growth is slowing, the resurgence of inflationary pressures has further narrowed the scope for monetary policy.
The IMF notes that the disinflation trend of recent years will be interrupted by this shock, with rising energy and food prices being the main drivers. Even if the conflict ends quickly, inflationary pressures are unlikely to dissipate rapidly. IMF economists warn that introducing fiscal stimulus amid rising inflation will place greater pressure on central banks to balance inflation and growth.
The report also specifically highlights that consumers still bear psychological trauma from the inflation shocks caused by the previous two crises—the pandemic and the Russia-Ukraine conflict—making them significantly more sensitive to any new round of price increases compared to before. Compared to when the Russia-Ukraine conflict erupted in 2022, labor markets have already weakened during this energy shock, and central banks have begun normalizing their balance sheets. If the scale of the shock is limited, inflation may remain relatively controllable, but this judgment carries considerable uncertainty.
Pierre-Olivier Gourinchas has called on policymakers worldwide to seek &#34;the right policies and stronger global cooperation&#34; to contain the spread of the shock.

The IMF warns that the Middle East conflict could drag global growth below 2%, nearing recession thresholds. The key variables lie in the Strait of Hormuz and energy supply: the longer the disruption and the deeper the damage, the more likely inflation will spiral out of control. Emerging markets face the heaviest impact, Europe is under pressure, while the US shows relative resilience. A resurgence in inflation has left central banks caught between supporting growth and controlling prices

- The International Monetary Fund (IMF) has downgraded its global economic growth forecast for 2026 to 3.1%, warning that ongoing conflicts in the Middle East could push growth below 2%, nearing recession levels.  
- The IMF's World Economic Outlook report emphasizes the significant impact of recent military actions on oil prices and economic projections, with emerging markets facing a notable decrease in expected growth rates.  
- In scenarios projected, prolonged conflicts could lead to severe economic ramifications, particularly for energy-dependent regions, highlighting the need for targeted policy responses to mitigate rising inflation and economic decline.
