This Month's Focus The Cost of War: Iran and the Global Economy. US and Israeli military operations against Iran beginning 28 February 2026 have triggered the largest oil supply disruption in history, with the Strait of Hormuz — through which 20% of global oil flows — effectively closed. The economic consequences are rippling through energy markets, inflation, monetary policy and supply chains worldwide.

Strait of Hormuz closure triggers biggest oil supply shock in history

Iranian forces declared the Strait of Hormuz "closed" on 2 March, disrupting the roughly 20 million barrels of oil and petroleum products that transit the chokepoint daily. Brent crude surged from around $65 before the conflict began to above $100 per barrel within days, with some analysts warning of $150 if the closure persists. The International Energy Agency called it the "greatest global energy security challenge in history." The IEA and US government coordinated a release of 400 million barrels from strategic reserves over 120 days — the largest in history — but analysts warn this falls well short of replacing Hormuz flows.

Central banks face stagflation dilemma as oil prices push up global inflation

The Iran conflict has put central banks in a bind not seen since the 1970s oil shocks. Higher energy prices are feeding cost-push inflation, yet the same price rises are suppressing growth by squeezing consumer spending and business investment. The Federal Reserve, already paused in its easing cycle, faces the prospect of inflation rising further while the labour market softens. The WTO estimates that if oil and gas prices remain elevated through 2026, global GDP growth could be cut by 0.3 percentage points. Economists at Capital Economics note that if Brent falls back to $70–80, the world economy "may absorb the shock with less disruption than many fear" — but the timeline depends entirely on the conflict's duration.

Iran's pre-war economy was already fractured — sanctions, inflation at 40%+

Before the February 2026 strikes, Iran's economy was already under severe strain. The World Bank had projected its economy would shrink in both 2025 and 2026, with annual inflation approaching 60% — driven by years of US and UN sanctions, a collapsing rial and declining oil export revenue. In September 2025, the UK, France and Germany triggered the "snapback" mechanism under the 2015 nuclear deal, restoring full UN sanctions. Despite this, China continued to purchase the majority of Iran's oil exports, and analysts did not expect China or Russia to provide meaningful relief. The conflict has intensified all existing pressures while cutting off Iran's remaining hard currency earnings from oil.

QatarEnergy declares force majeure — LNG supply crunch hits Europe and Asia

QatarEnergy, the world's largest LNG producer, declared force majeure on contracts following disruption to its Ras Laffan export hub. Approximately 20% of global LNG trade — previously flowing through or near the Strait of Hormuz — was effectively removed from the market. European gas prices surged 63% and Asian prices rose 54% in a single week. The disruption has delayed Qatar's major North Field East expansion project, which was expected to add significant new supply to global markets. US LNG exporters emerged as unexpected beneficiaries, with demand for American liquefied gas surging as buyers scrambled for alternatives.

Gulf states face mass exodus of low-income migrant workers as conflict deepens

The conflict has devastated the labour market across Gulf states, with a mass exodus of the estimated 25 million low-income migrant workers — from South Asia, Southeast Asia and Africa — who form the backbone of economies in the UAE, Qatar, Saudi Arabia and Kuwait. The ILO warned of severe remittance shocks for origin countries including Pakistan, the Philippines and Nepal, which rely heavily on money sent home from Gulf workers. Dubai, long seen as a beacon for economic migrants, has seen its reputation as a stable destination shattered, with analysts describing the war as destroying the "illusion" of Gulf cities as reliably safe environments for migrant labour.

Governments across Asia and Europe scramble to subsidise fuel as prices surge

Faced with soaring energy costs, governments across Asia, Europe and the developing world have implemented emergency fuel subsidies and price controls. Sri Lanka reintroduced fuel rationing and a four-day government work week. Bhutan's Department of Trade appealed for calm as queues formed at fuel stations. European governments have drawn comparisons with the 2021–22 energy crisis following Russia's invasion of Ukraine, when billions in subsidies were deployed. The UK, which cut foreign aid to Middle Eastern and African countries by over 50% to fund military spending increases, faces criticism that its own consumers will bear a significant cost.
