The International Monetary Fund has downgraded its global growth outlook, warning that escalating conflict in the Middle East - now compounded by a near shutdown of the Strait of Hormuz - is disrupting trade, fueling inflation and complicating policymaking worldwide. Growth is now expected to slow to roughly 3.1% in 2026, down from earlier projections of about 3.4%, with risks tilted further to the downside.

Why it matters

The sudden collapse of shipping through the Strait of Hormuz is forcing producers worldwide to scramble for alternative sources of key inputs, driving up costs across multiple sectors, from agriculture to manufacturing. The burden is expected to fall unevenly, with lower-income regions facing the most severe consequences. Even if shipping resumes in the near term, the effects of the disruption could persist for months or longer, as damage to regional refining capacity and export infrastructure may take years to fully repair.

The details

On April 12, Donald Trump announced a blockade of 'any and all ships' attempting to pass through the Strait of Hormuz, a critical global shipping corridor. The move followed weeks of threats from Iran targeting vessels that did not pay multimillion-dollar transit fees. Together, the actions have effectively halted traffic through one of the world's most important commodity routes. Before the conflict, the Gulf region accounted for a significant share of global commodity exports, including roughly 20% of seaborne jet fuel, 10% of diesel, 23% of ammonia and 33% of helium production. It also supplied half of global seaborne sulfur and about 9% of aluminum.

What they’re saying

“Global growth momentum entering 2026 has been 'halted' by the conflict, which has driven up energy prices and heightened uncertainty.”

— International Monetary Fund

“The closure represents a dual shock: an immediate supply disruption and a longer-term restructuring of global trade flows.”

— Atlantic Council

What’s next

The IMF emphasized that policymakers now face a narrow path forward: balancing inflation control with economic support while maintaining financial stability in an increasingly uncertain global environment.

The takeaway

The disruption in the Strait of Hormuz is expected to have far-reaching economic consequences, with lower-income regions facing the brunt of the impact. Policymakers will need to navigate a delicate balance between controlling inflation and supporting economic growth in the face of this geopolitical crisis.
