A blockade, a toll, and a Fed chair running out of room
Economic Affairs | The Navarro Report | July 13, 2026
NEW YORK — Wall Street opened the week pricing in a Federal Reserve rate cut. By Monday afternoon, it was pricing in the opposite, after President Trump declared the United States would reimpose a naval blockade on Iranian shipping through the Strait of Hormuz and charge a toll for the privilege of using it.
“We are going to keep the Strait. We will probably run it,” Trump told Fox and Friends Monday morning, adding that the U.S. would become the “guardian” of the waterway. Hours later, in a Truth Social post, he made the plan concrete: a 20 percent fee “on all cargo shipped” through Hormuz, with the blockade of Iranian ports set to resume Tuesday at 4 p.m. The strait, he wrote, “is OPEN, and will remain OPEN, with or without Iran.”
Markets took the announcement as confirmation that the fragile U.S.-Iran ceasefire, in place since earlier this year, had effectively collapsed. Brent crude jumped as much as 9.6 percent intraday, its largest single-day move since May 2020, before settling near $83 a barrel; West Texas Intermediate closed up 9.4 percent at $78.14. Roughly one-fifth of the world’s oil supply normally transits Hormuz, and traffic through the strait had only recently begun recovering from the disruptions that followed Iran’s initial closure attempt in late February.
Equity markets moved in the opposite direction. The S&P 500 fell 0.79 percent to 7,515.34, the Nasdaq Composite dropped 1.55 percent to 25,873.18, and the Dow Jones Industrial Average slipped a more modest 0.26 percent to 52,498.64, cushioned by energy names that rallied alongside crude. The Energy Select Sector SPDR Fund rose roughly 3 percent even as growth and technology stocks broadly sold off.
The reaction from institutions that price geopolitical risk for a living was blunt. “The possibility that the Iranian regime walks away from the MoU until after the mid-term US elections has also risen, a scenario which would most likely see higher for longer oil prices,” Citi analysts wrote in a note published Tuesday, referring to the memorandum of understanding that had underpinned the ceasefire. The International Maritime Organization, for its part, rejected the toll proposal outright within hours, with its secretary-general saying the body “stands firmly against charging fees for passage through straits used for international navigation.” The U.S. Treasury Department has separately warned that companies paying Iran for transit rights, under a similar scheme Tehran had proposed, would risk sanctions violations — a warning that now sits awkwardly next to Washington’s own toll plan.
The more consequential audience for Monday’s announcement may not have been shippers at all, but the Federal Reserve. Chair Kevin Warsh, seven weeks into the job, has kept the federal funds rate at 3.50 to 3.75 percent through his first meeting in June, while the committee’s dot plot showed more officials leaning toward a hike than a cut for the first time this cycle. Core inflation, excluding food and energy, has hovered near 2.9 percent year over year — elevated, but arguably manageable. The headline number is the problem: May’s Consumer Price Index rose 4.2 percent annually, driven overwhelmingly by a 23.5 percent surge in energy costs tied directly to the conflict.
“Prices are too high,” Warsh told a policy panel at the European Central Bank’s Sintra forum, while declining to signal the committee’s next move. That data-dependent posture is now being tested in real time. Prediction markets tracked odds of a July hike rising through Monday as oil prices climbed, and Fed Governor Christopher Waller warned publicly that the central bank “must not repeat the mistakes of 2021 and 2022,” when policymakers waited too long to raise rates as inflation took hold — while cautioning against overcorrecting in the other direction. The Fed’s own June statement had already flagged that “inflation remains elevated relative to the Committee’s 2% goal.”
The timing compounds the uncertainty: June’s CPI report lands Tuesday, and economists surveyed by Dow Jones expect annual inflation to have cooled to about 3.8 percent from May’s 4.2 percent — good news that a fresh oil shock could partially erase before the ink is dry. A Barclays note circulated Monday argued inflation pressures have already broadened beyond energy alone, meaning even a retreat in oil prices may not fully resolve the Fed’s dilemma.
For a Fed chair seven weeks into the job and still without a personal rate projection on the board, Monday’s blockade announcement removed any illusion that monetary policy could be set independent of what happens roughly 7,000 miles away in a 33-mile-wide shipping lane. Markets will get their next read on Tuesday, when June’s inflation data arrives — and when Wall Street’s major banks begin reporting second-quarter earnings against a macro backdrop that changed materially over a single afternoon.
