Economic Shockwaves from the Iran War: Emerging Markets, Inflation, and Energy Supply

The U.S.–Israeli campaign against Iran began on 28 February 2026 and led Tehran to close the Strait of Hormuz on 4 March. The strait, which moves about 20 % of world oil and gas, saw daily traffic fall from roughly 130 vessels to fewer than ten. Qatar recorded its first trade deficit—$1.2 billion in March—after exports dropped over 90 % and imports were halved; JPMorgan projects a 9 % GDP contraction, deeper than the IMF’s 6.1 % forecast for Iran. Higher crude prices pushed U.S. CPI to 3.3 % YoY in March with energy up 12.5 %; the Eurozone’s CPI rose to 2.6 % as energy inflation jumped to 5.1 %; China’s CPI eased to 1.0 % despite oil gains. Central banks in the Philippines, Turkey, Poland, Hungary, the Czech Republic, India and South Africa have shifted toward tighter policy, citing “second-round effects.” Fiscal stress is evident in Egypt, where the pound fell 9 % and debt service exceeds $30 billion, in Sri Lanka’s reinstated fuel subsidies, and in Pakistan’s foreign-exchange reserves covering under three months of basic imports.

The IMF warned the shock “could trigger a global recession” and signaled $20-50 billion of additional emergency financing. The World Bank and IMF cut the growth outlook for emerging and developing economies to 3.9 % from 4.2 %. Saudi Arabia and the UAE have maximised pipelines—7 million and 1.8 million barrels per day respectively—to bypass Hormuz, while Iraq advances a $4.6 billion Basra–Haditha segment.

Citi analyst Joanna Chua warned that fiscal risks are rising in emerging markets as governments cap prices and extend subsidies. Other analysts caution that blanket subsidies may inflate demand without targeting those most in need.

Energy-inflation estimates diverge: U.S. energy inflation rose 12.5 % YoY, while Eurozone energy inflation moved from –3.1 % to +5.1 % in a month. IMF growth projections for emerging markets range from 3.9 % to the earlier 4.2 %. Brent-crude 2026 average forecasts span $63.85 to $82.85 per barrel. Impacts on sub-Saharan economies remain unquantified.

Global inflation rises as energy prices increase

• “A full-fledged impact is coming and it is not far away,” — Ali Ahmed Al-Kuwari, Qatar Finance Minister

• “We see growing fiscal risks in EM from capping prices, from tax cuts and subsidies if this energy shock is more persistent,” — Joanna Chua, Citi

• “We have a negative supply shock,” — Kristalina Georgieva, IMF Managing Director

The IMF is preparing a $20-50 billion emergency package as Gulf states accelerate pipeline projects to double capacity. In the United States, the 60-day war-powers deadline expires on 1 May, after which congressional approval will be required to sustain operations. The interaction of fiscal stress, tighter monetary policy, and expanding infrastructure will shape the medium-term trajectory of emerging economies.
