What U.S. Strikes on Iran Could Mean for Oil and Global Markets

On February 28, 2026, the United States worked with Israel to attack Iran’s military and nuclear facilities. In response, Iran quickly launched missiles on Israeli and US bases in the Gulf. As markets open on March 2, investors are assessing how these escalations will affect oil prices, the stock market, and the global economy as a whole.

Around 20 million barrels of oil are transported through the Strait of Hormuz each day, which is a crucial waterway between Iran and Oman. That amounts to almost 20% of the entire world’s oil consumption. Saudi Arabia, the UAE, Kuwait, Iraq, and Qatar all depend on this trade route for their exports. If trade inside the Strait is disrupted, global energy supply could tighten very quickly. 

Prior to the strikes, crude oil was trading around $73 per barrel. Analysts expect prices to rise as markets reopen, possibly to around $80 per barrel in an initial reaction. If the conflict escalates even more, prices could rise even further. Modeling from economic research firms predicts that the closure of the Strait of Hormuz could push oil prices well above $100 per barrel.

Oil price increases affect the global economy in many ways. Higher crude prices drive higher gas and diesel prices. Costs of transportation tend to rise, and the shipping of goods becomes more expensive. Airlines face higher fuel costs. Businesses usually pass these costs onto consumers, which leads to higher levels of inflation. When inflation rises, central banks decide whether to maintain high interest rates or provide economic support. 

If oil prices spike and remain high, it could cause an economic recession. Models estimate that supply disruptions could reduce GDP growth in oil-importing countries and slow overall economic growth. However, previous conflicts show that not all Middle Eastern tensions produce lasting damage to the economy. In past cases like the Gulf War in 1991 and regional conflicts in the 2000s, oil prices spiked temporarily before stabilizing in the long run.

In the near future, different sectors will react differently to the situation. Energy companies might benefit from rising oil prices, while industries sensitive to fuel costs could face pressure. In times of geopolitical crisis, investors often move their money into “safe-haven” assets like gold and defense stocks. This is due to the rise in market volatility as uncertainty increases. 

The key question is whether the conflict will remain contained or begin to interfere with oil flows throughout the Strait of Hormuz. If exports continue, the economic impact may only lead to short-term volatility. However, if tensions escalate, higher energy prices could feed inflation and slow global growth. Ultimately, the financial consequences will depend on whether energy supply, trade routes, and investor confidence remain stable in the days ahead.
