The global economy has weathered multiple shocks over the past year, including trade disputes, political instability, and uneven growth across major regions. Yet a widening conflict involving Iran introduces a distinct and potentially more immediate threat: disruption to energy supplies. At the center of this risk lies the Strait of Hormuz, a narrow maritime corridor along Iran’s southern coast through which roughly one in five barrels of the world’s oil flows daily. Any sustained interruption in this passage could rapidly transmit stress from commodity markets to inflation, growth, and financial stability.

According to reporting highlighted by the Financial Times, analysts broadly outline two potential scenarios. The first and most severe involves prolonged disruption to tanker traffic through the Strait, whether due to military escalation, mining of sea lanes, or insurers withdrawing coverage for vessels. Such a scenario would constitute a direct supply shock to global oil markets. Brent crude, currently trading in the low-to-mid 70 dollar range per barrel, could surge beyond 100 dollars, with upside risks if shipping companies reroute or suspend operations entirely.

The second, less extreme outcome involves targeted sanctions or military strikes that curb Iran’s own exports without fully closing the Strait. Iran produces slightly under 3.5 million barrels per day, representing less than 3 percent of global output. While significant, this loss could be partially offset if other producers increase supply. In that case, oil prices might climb toward 80 dollars per barrel — a level that would strain consumers but remain manageable for most economies.

OPEC+ has already signaled a modest production increase, suggesting that producers are attempting to stabilize expectations before panic buying or speculative hoarding takes hold. However, spare capacity is concentrated among a few Gulf producers, meaning logistical and political constraints could limit how quickly additional supply reaches markets.

For the United States, the implications differ from past oil crises. Domestic shale production has reduced reliance on imports, but American fuel prices remain tied to global benchmarks. Economists estimate that sustained oil prices around 100 dollars could push US inflation above 4 percent, complicating the Federal Reserve’s plans to ease monetary policy later this year. Higher gasoline costs would directly affect household spending, while elevated transport expenses could ripple through supply chains.

Asia stands out as the most vulnerable region. More than 80 percent of crude oil and liquefied natural gas transiting Hormuz is destined for Asian markets, including China, India, Japan, and South Korea. For manufacturing-driven economies dependent on imported energy, higher oil prices translate into increased production costs, weaker trade balances, and potential currency pressures.

India’s exposure is particularly acute. The country imports over 80 percent of its crude requirements, making it highly sensitive to price spikes. A move toward 100 dollar oil would widen the current account deficit, pressure the rupee, and potentially force the government to choose between absorbing fuel subsidies or passing costs to consumers. Elevated energy prices would also complicate the Reserve Bank of India’s inflation management strategy, especially if food prices remain volatile.

Europe would experience a different but still significant impact. Although eurozone inflation has recently moderated, a sharp rise in oil and liquefied natural gas prices could reverse that trend. Central banks such as the European Central Bank and the Bank of England would face difficult trade-offs between controlling inflation and supporting fragile growth.

Beyond the direct energy channel, the broader risk lies in market confidence. Financial markets are already navigating trade tensions, geopolitical uncertainty, and uneven corporate earnings. A prolonged Gulf conflict could trigger risk-off sentiment, pushing investors toward safe-haven assets such as the US dollar and government bonds. Historically, oil shocks have strengthened the dollar, which in turn tightens financial conditions globally by raising the cost of servicing dollar-denominated debt.
