White House says U.S. is developing plan to secure Strait of Hormuz as tensions rise

The White House said on March 5 that the United States is "actively developing plans to secure the Strait of Hormuz," naming the Departments of Defense and Energy and U.S. Navy planners as participants, a sign the administration is moving from rhetoric toward formal interagency work on a key maritime chokepoint. Press secretary Karoline Leavitt delivered the statement as the White House sought to reconcile earlier, more immediate presidential directives with formal planning language.

In early March President Donald J. Trump posted a directive on his Truth Social account ordering the U.S. International Development Finance Corporation to underwrite maritime trade and threatening naval escorts. As reproduced by POLITICO/Greenwire, the post said: "Effective IMMEDIATELY, I have ordered the United States Development Finance Corporation (DFC) to provide, at a very reasonable price, political risk insurance and guarantees for the Financial Security of ALL Maritime Trade, especially Energy, traveling through the Gulf. This will be available to all Shipping Lines. If necessary, the United States Navy will begin escorting tankers through the Strait of Hormuz, as soon as possible."

Market analyses tied to the president's March 3 post said the pledge helped reverse an earlier risk selloff. MarketPulse reported markets "shed their persistent morning anxiety" and undertook a "massive U-turn" after the post, framing the DFC guarantee and escort prospect as calming forces for energy and shipping markets that had reacted to Iranian warnings.

Tensions on the water remain acute. Reuters reported that Iranian state media quoted a senior Islamic Revolutionary Guard Corps official saying the Strait of Hormuz "is closed" and that Iran would fire on any ship trying to pass. The claim is being reported as an Iranian media statement; U.S. officials have not confirmed a physical closure.

Beyond near-term operational moves, a separate policy Plan summarized by legal advisers at Norton Rose Fulbright outlines a longer-term industrial and fiscal strategy to buttress U.S. maritime resilience. The Plan recommends creating a Strategic Commercial Fleet, boosting domestic production of critical marine components such as "large marine engines, reduction gears and propellers," and substantial regulatory reform. It also proposes an "infrastructure or security fee" on foreign-built commercial vessels calling at U.S. ports, offering two revenue scenarios: a fee of 1 cent per kilogram would yield "roughly $66 billion in revenue over ten years," while a fee of 25 cents per kilogram "would yield close to $1.5 trillion in revenue," funds the Plan says could finance a Maritime Security Trust Fund.

The administration's mix of immediate presidential orders, an interagency planning declaration, and long-term industrial proposals creates legal and operational questions. The White House statement emphasizes planning; the president's social post asserts an immediate DFC mandate and conditional naval escorts. Officials have not released operational orders, rules of engagement, DFC underwriting terms, or schedules for escorts, and the White House readout included a truncated statistic about the strait that was not completed in its text.

For markets, shipping companies, and insurers, the policy package signals both support and uncertainty: potential state-backed political risk insurance could reduce war-risk premiums, while the specter of confrontations in the strait keeps freight and energy supply chains vulnerable. Analysts and lawmakers will watch for DFC guidance, Department of Defense confirmations of any escort missions, and diplomatic outreach to Gulf littoral states as the administration moves from proclamation to implementation.
