Washington’s pledge to escort oil tankers through the Strait of Hormuz when “militarily possible” is aimed at calming traders and propping up confidence in global supply, not at guaranteeing safe passage in an active shooting war with Iran. Treasury Secretary Scott Bessent told Sky News in March 2026 that the U.S. Navy would provide escorts “perhaps with an international coalition” once the Pentagon has complete control of the skies and Iran’s missile rebuild capacity is degraded. On the same day, Energy Secretary Chris Wright told CNBC the U.S. is “simply not ready” to start escorts and that the Navy could be in position only by the end of the month. The gap between the two messages is the story: one reassures markets, the other reflects the real constraints.
The escort pledge is market reassurance, not a near-term military plan
Bessent’s announcement to Sky News framed escort operations as a coming phase of the U.S. response to Iran’s attacks on shipping. He said escorts would begin “as soon as it is militarily possible” and that some tankers, including Iranian- and Chinese-flagged vessels, were already transiting, suggesting the waterway had not been fully mined. CNBC reported that the Treasury secretary was signalling a “series of announcements” to support oil trade in the Gulf, including insurance for tankers and a 400-million-barrel release from strategic petroleum reserves. The effect is to give markets a narrative of eventual normality.
Wright’s remarks to CNBC undercut that timeline. He stated that the U.S. is “simply not ready” to escort tankers through the strait and that military assets are currently focused on destroying Iran’s offensive capabilities. Reuters reported in early March 2026 that the U.S. Navy had been refusing daily escort requests from the shipping industry because the risks were still too high. Hundreds of vessels remain stuck in the Persian Gulf; escorting even a fraction would demand an inordinate amount of time and naval coverage. The situation is not comparable to the 1987–88 tanker war, when the Navy escorted Kuwaiti-flagged ships without simultaneously waging a full-scale campaign against Iran.
Iran has escalated since the conflict widened in late February 2026. Iran’s new supreme leader, Mojtaba Khamenei, has said the strait should stay closed as a “tool to pressure the enemy” and that all U.S. bases in the region would be attacked unless they shut down. CNN reported that Iran had begun laying mines and that 80–90% of its small boats and minelayers remained operational. More than a dozen vessels had been attacked since the war began. NPR and other outlets described a mix of threats: mines, drones, and missiles. In that context, promising escorts “when militarily possible” is a conditional, backward-looking commitment, not a near-term guarantee of safe transit.
Oil markets have already priced in the gap
Brent crude rose above $100 a barrel in March 2026 as Hormuz traffic neared a standstill; the International Energy Agency approved a 400-million-barrel emergency release from strategic reserves. Reuters and Bloomberg reported that analysts saw oil staying elevated while Hormuz risks continued, and that a prolonged closure could push prices well into triple digits. The U.S. has paired the escort narrative with other market supports: insurance for tankers and the reserve release. None of that changes the fact that the Navy is not yet escorting, and that traders are being asked to believe in a future capability rather than a current one. The 1987 Operation Earnest Will precedent is often cited, but in that episode the Navy was not simultaneously fighting a full-scale air and missile campaign against Iran; the Bridgeton was still hit by a mine in July 1987 despite U.S. escort. Today the environment is more contested, and the promise of escorts is a signal to hold nerve, not proof that transit is safe.
What This Actually Means
The Biden administration is trying to do two things at once: reassure oil markets and allies that the U.S. will eventually restore order in the Gulf, and avoid overpromising when the military is still in the phase of degrading Iran’s capabilities. Bessent’s language is chosen for traders and diplomats; Wright’s is chosen for the reality of force posture. Until the Navy can credibly guarantee that escorted convoys will not be hit by mines, drones, or missiles, the pledge is more theatre than plan. Oil prices had already surged above $100 a barrel; the 400-million-barrel reserve release and the promise of future escorts are as much about managing volatility as about physical supply.
Bessent told Sky News that escorts would start once the U.S. had “complete control of the skies” and Iran’s “rebuilding capabilities for the missiles completely degraded.” That is a high bar, and Wright’s “end of March” timeline is itself conditional. For now, the shipping industry is left with daily refusals and the assurance that escorts are coming. The gap between the Treasury message and the Navy’s posture is the real takeaway: the promise is market theatre, not a military plan.
What is the Strait of Hormuz?
The Strait of Hormuz is a narrow waterway between Iran to the north and Oman and the United Arab Emirates to the south, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is roughly 21 miles wide at its narrowest point, with navigable shipping lanes only about 2 miles wide in each direction. According to the IEA and Reuters, about 20–25% of the world’s seaborne oil passes through the strait—around 20 million barrels per day of crude and oil products. Saudi Arabia, the UAE, Kuwait, Iraq, Qatar, and Iran depend on it for exports; most Gulf oil has no alternative sea route. Qatar ships nearly all of its LNG through the strait. When traffic is disrupted or halted, global oil and gas markets react within days.
