Brent Crude Jumps Past $111 as Hormuz Blockade Threatens European Oil Supply

A deepening crisis in the Strait of Hormuz is threatening to trigger physical oil shortages in Europe within weeks, sending crude prices surging and fueling a selloff in global bonds.

Oil markets are operating under a “veneer of stability,” strategists warned Monday, as the continued blockade of a critical waterway pushes Brent crude futures past $111 a barrel and forces a painful repricing of global inflation and interest rate expectations. The standoff, which has choked off nearly 20 percent of the world’s oil supply, is now the primary driver of market volatility.

“The Strait of Hormuz blockade will remain the dominant market driver because there is no clear endgame in sight while the buffer from global oil inventories is shrinking fast,” said Elias Haddad, global head of markets strategy at Brown Brothers Harriman. “As a result, crude oil prices are vulnerable to more upside, weighing on both global bond and equity markets.”

The market reaction was swift and broad-based. Brent crude, the global benchmark, rose 1.9 percent to $111.34 a barrel, while U.S. crude climbed 2.2 percent. The stress was more apparent in forward markets, where futures for December delivery hit a contract high. The move rippled into debt markets, with the U.S. 10-year Treasury yield hitting a 15-month high of 4.631 percent, while Japan’s 30-year yield climbed to a level not seen since 1999.

The core issue for markets is the prospect of a new, persistent wave of inflation driven by energy costs, which would force central banks to keep interest rates higher for longer, or even hike them further. Analysts at Capital Economics warned that if the strait remains closed through the end of the year, inventories could reach critical levels by the end of June, potentially sending Brent to $140 a barrel and leading to a global recession.

Bond Selloff Intensifies

The repricing of inflation risk has hammered global bond markets. U.S. government bonds are coming off their worst week in a year, with the 30-year Treasury yield moving toward a two-decade high above 5 percent. The selloff is global, with Japanese 10- and 20-year rates rising about 10 basis points to their highest levels since 1996.

This "mini rate shock," as described by Kyle Rodda, a senior analyst at Capital.com, has completely flipped the script for the Federal Reserve. Where traders once priced in rate cuts for 2026, a hike by March is now seen as a near certainty. The dynamic creates a difficult headwind for equity markets, which have for months been powered by enthusiasm around artificial intelligence.

Geopolitical Deadlock

Hopes for a swift resolution are fading. Iran’s semi-official Mehr news agency stated that Washington offered “no tangible concessions,” leading to an “impasse in the negotiations.” The rhetoric from the U.S. has been equally firm, with President Donald Trump warning that the “clock is ticking” for Iran to strike a deal.

The fragility of the situation was highlighted by a series of drone attacks over the weekend. A strike sparked a fire at a United Arab Emirates nuclear plant, while Saudi Arabia reported intercepting three drones, underscoring the risk of a wider regional conflict that could keep the vital shipping lane closed indefinitely. Finance ministers from the Group-of-Seven are set to discuss the debt selloff and the Hormuz crisis when they meet in Paris this week, though their options appear limited.
