Treasury Secretary Bessent announced the Navy will escort oil tankers through the Strait of Hormuz 'as soon as militarily possible.' Brent crude closed above one hundred dollars for the first time since August 2022. The market read this as a plan to reopen the strait. It is more accurately a preview of why the cost structure won't snap back.
Treasury Secretary Scott Bessent told Sky News on Thursday that the U.S. Navy will begin escorting oil tankers through the Strait of Hormuz "as soon as militarily possible." The conditions he named — complete air superiority and Iran's missile capabilities "completely degraded" — describe a weeks-long timeline at minimum. Energy Secretary Chris Wright was more direct: "It'll happen relatively soon but it can't happen now." Brent crude closed above one hundred dollars a barrel for the first time since August 2022.
The market read the escort announcement as a plan to reopen the strait. It is more accurately a confession that the strait cannot be reopened yet — and a preview of what "reopened" will actually look like.
The Speed of the Slowest Ship
A convoy moves at the speed of its slowest vessel. This was the defining constraint of the Atlantic convoy system in World War II, where fast crossings took thirteen to fourteen days and slow convoys took sixteen to seventeen — both limited by the weakest members in the group. Beyond the speed penalty, convoys impose scheduling rigidity: ships wait in port for the next departure window rather than sailing when loaded. Port congestion spikes as entire convoys unload simultaneously. Flexible routing — the ability to chart the most efficient individual course — disappears entirely.
The U.S. Navy has not escorted commercial shipping through a contested waterway at this scale since the Tanker War of the late 1980s. That operation, Earnest Will, required dedicated destroyers and minesweepers for fourteen months to protect Kuwaiti tankers reflagged as American vessels. Twenty-one percent of the world's oil transits the Strait of Hormuz. Escorting it requires not just naval capacity but a logistical architecture — assembly points, convoy schedules, communication protocols, minesweeping corridors — that adds days to every voyage even after the shooting stops.
The Response Stack
Every crisis response depletes something that isn't easily restored.
The IEA coordinated a four-hundred-million-barrel release from strategic petroleum reserves — the largest in history. Those barrels are now gone. The United States has already drawn its SPR to sixty percent of capacity. Refilling takes years and competes with commercial demand.
War risk premiums for ships transiting Hormuz have risen fivefold, from roughly a quarter of one percent of hull value to between one and a half and three percent per voyage. For a supertanker valued at eighty million dollars, that is an additional one to two million dollars per transit in insurance alone. Historically, these premiums decline after conflicts but never return to pre-crisis levels. After years of elevated Black Sea and Red Sea pricing, underwriters now maintain scenario pricing as a permanent feature — a baseline surcharge that accounts for the possibility of relapse.
Ships rerouting around the Cape of Good Hope add ten to fourteen days and thirty-five hundred nautical miles to each voyage. Fuel costs rise roughly thirty percent. Container surcharges of eight hundred to four thousand dollars per box took effect on March 2 and have shown no sign of reversal. Airlines have repriced fuel surcharges. Chemical feedstock contracts have been renegotiated.
Each of these responses is individually rational. Collectively, they form a stack of costs that compound — and each layer has its own decay rate. Some snap back in weeks. Others take quarters. A few become permanent features of the cost structure.
The Ratchet
The deeper pattern is that crisis responses calcify into structural costs.
When Houthi attacks disrupted Red Sea shipping in 2024, the rerouting around the Cape was supposed to be temporary. Eighteen months later, premiums in the Red Sea had declined from their peak but remained multiples of pre-crisis levels. The infrastructure built to service the longer route — fuel stops, port capacity at alternative hubs, revised supply chain contracts — created constituencies that benefited from the new routing. The temporary became the baseline.
The same pattern is unfolding now at larger scale. The escort system, once operational, will impose its own cost structure: slower transit times, scheduling rigidity, military coordination overhead, and insurance premiums that reflect not the current risk but the demonstrated maximum risk. Even if Iran reopens the strait tomorrow, the market has priced a new floor. Underwriters will not forget that the strait closed. Shipping companies will not unwind their Cape contracts overnight. Airlines will not reverse fuel surcharges the week the news cycle shifts.
This is the gap that inflation models miss. They capture the price shock — oil's move from seventy to one hundred dollars — but not the response costs that persist independently of the commodity price. Slower shipping, depleted reserves, repriced insurance, and military logistics overhead are all inflationary channels that compound separately from what crude does next. The crisis created the shock. The response created the floor.
The IEA called this the largest supply disruption in history. What makes it historically unprecedented is not the disruption itself but the scale of the response — and the structural costs that response will leave behind long after the last convoy clears the strait.
