Brent crude tops $81 as US-Iran standoff squeezes consumers

Brent crude surged past $81 a barrel Monday after the US reimposed a blockade on Iranian shipping in the Strait of Hormuz, compounding consumer pressure from elevated interest rates and high margin debt, macro strategist Max Wasserman said.

"There's no relief in sight," Wasserman said, pointing to a cooldown in CPI that has failed to offset persistent headwinds from the US-Iran confrontation. The Fed faces a political tightrope as it weighs rate policy against rising energy costs, he added.

Oil prices jumped 5% to $79.37 a barrel Monday before extending gains past $81 after President Donald Trump declared the US the "Guardian of the Hormuz Strait" and announced a 20% toll on cargo passing through the waterway. The escalation marks the latest cycle in a conflict that began with US-Israeli strikes on Tehran in late February, when oil traded at $72.48 a barrel. Prices reached highs of $120 in April before a fragile interim truce was signed last month.

The renewed disruption threatens to keep gasoline prices elevated just as the Fed navigates competing pressures. Goldman Sachs analysts wrote that "recent attacks highlight how uncertain Gulf exports remain and that a serious re-escalation could re-intensify the short-run upside risk to oil prices."

The equity market reaction was swift. The Nasdaq fell 1% and the S&P 500 dropped 0.4% in afternoon trading on Wall Street. Asian markets suffered deeper losses, with South Korea's Kospi plunging 8% and Japan's Nikkei 225 sliding 2%. Chipmakers were hit hardest — SK Hynix slumped 15% and Samsung Electronics sank 10%. Gold fell 1.4% to $4,083 an ounce as higher oil prices stoked fears that central banks may keep rates elevated, reducing the appeal of non-yielding assets.

Strait of Hormuz disruption deepens

Only six vessels crossed the strait on Sunday, the fewest in five weeks, according to data analytics firm Kpler. The waterway normally handles about a fifth of the world's oil supply. Iran's Islamic Revolutionary Guard Corps said it stopped two ships by shutting down their systems, while the US Central Command said it launched further strikes to degrade Iran's ability to attack commercial vessels.

Trump's proposed 20% shipping fee has no mechanism or billing system in place, shipping executives said. Iran's Foreign Minister Abbas Araghchi called the charge excessive and reasserted Iran's claim over the waterway.

Fed constrained as inflation risks mount

The oil price shock complicates the Fed's rate path. Before the latest escalation, markets had priced in a potential rate cut later this year as CPI showed signs of cooling. Rising energy costs threaten to reverse that progress, narrowing the central bank's room to ease. Wasserman described the Fed as navigating a "political tightrope," constrained by both inflation risks and political pressure.

The last time oil prices surged past $120 in April, the S&P 500 fell 6% over the following three weeks while consumer sentiment dropped to its lowest level since the 2022 inflation peak. Opec on Monday cut its global demand growth forecast for 2026 to 780,000 barrels a day from 970,000, the third consecutive downward revision, signaling that the cartel expects the economic drag from higher prices to curb consumption.
