Oil Tops $100 as Stalled Iran Talks Stoke New Inflation Fears

West Texas Intermediate crude surged 2.5% to trade over $100 a barrel Tuesday after U.S. President Trump said a ceasefire with Iran was on “life support,” increasing concerns that a historic supply disruption will continue to fuel global inflation.

"People are now realizing that the pitch they got about lowering the cost of goods and services is a fairy tale," said Brian Bethune, an economics professor at Boston College. "They were basically treading water with their nose just above the surface, now they are being pulled down below the surface. There is no air to breathe."

The move in oil reverberated across markets, with the 10-year U.S. Treasury yield rising to 4.421% and the dollar index (DXY) gaining 0.2% on safe-haven demand. U.S. stock futures pointed lower after the S&P 500 and Nasdaq closed at records Monday, with traders now focused on inflation data due later Tuesday that is forecast to show headline CPI accelerating to 3.7 percent.

The standoff, which has kept the Strait of Hormuz effectively closed for 10 weeks, is forcing economists to re-evaluate inflation forecasts for the remainder of 2026. A higher-than-expected CPI print could pressure the Federal Reserve to maintain its hawkish stance, weighing on equity valuations just as surging energy costs threaten to erode corporate earnings and consumer spending.

The geopolitical tensions pushed Brent crude, the international benchmark, up 2.1% to $106.36 a barrel. The surge in energy prices is "bleeding through" to the wider economy, according to panelist EJ Antoni on 'The Bottom Line,' reflecting a growing worry that sustained high fuel costs will become embedded in consumer prices. "Oil prices climbed for a second day as the global oil market continued to tighten amid limited prospects for a reopening of the Strait of Hormuz," analysts at Saxo Bank said.

The Largest Disruption in History

The conflict has removed a staggering amount of oil from the market. The market has lost nearly 1 billion barrels of oil during the 10 weeks that Iran has managed to effectively close the Strait of Hormuz, according to statements from the CEOs of Saudi Aramco and Shell.

"That this is the largest oil supply disruption in the history of the oil market is neither an exaggeration nor controversial," Martijn Rats, a commodities strategist at Morgan Stanley, told clients in a Monday note.

The loss of supply from the Persian Gulf totaled 12.3 million barrels per day from April 8 to May 8. While other producers, led by the U.S., have offset some of the losses by increasing exports by 5.5 million bpd, the net shortfall has drained inventories and created a significant challenge for global markets.

Why Not $150?

Given the scale of the disruption, some analysts have questioned why prices have not spiked to the highs seen in previous, smaller crises, such as the $130 per barrel price reached after Russia's 2022 invasion of Ukraine. According to analysis from Morgan Stanley and JPMorgan, several factors are capping the rally.

The single biggest factor is a dramatic reduction in crude imports by China, which fell by 5.5 million barrels per day from about 14 million bpd a year ago. Rather than refusing cargoes, China's state-owned trading houses are reselling them on the spot market, redistributing supply.

The market also entered 2026 with a significant surplus of 2 million bpd and ample inventories, which are now being consumed. Furthermore, producers outside the Middle East, particularly the U.S., have surged net exports by 5.5 million bpd, with America alone accounting for a 3.8 million bpd increase—a level Morgan Stanley's Rats said "we would have struggled to forecast at the start of the conflict."

Finally, JPMorgan's head of global commodities strategy, Natasha Kaneva, noted that the disruption is being expressed more in the prices of refined products like gasoline and diesel, which have surged 60% to 120% in Asia, compared to a 40% rise in crude. This suggests the market could rebalance through demand destruction for finished products rather than another major spike in crude oil itself.
