U.S. President Donald Trump states that no vessels may enter or exit the Strait of Hormuz without U.S. Navy approval
U.S. President Donald Trump stated on social media that no vessels may enter or exit the Strait of Hormuz without U.S. Navy approval, claiming that the waterway is "tightly blocked" and that the blockade will continue until an agreement is reached between Iran and the U.S. U.S. officials told English media that the military operation focuses on blocking maritime traffic in and out of Iranian ports, while still allowing controlled passage for vessels from other countries, although the overall risk and uncertainty have significantly increased.
Previously, the Pentagon submitted an assessment to Congress stating that completely clearing the mines laid by Iran could take months. The U.S. military is currently more focused on "setting conditions," including expanding mine-sweeping and escort groups, as well as conducting boarding inspections on suspected violators. English analyses generally point out that referring to the Strait of Hormuz as a "blockade" rather than "protecting the waterway" effectively incorporates this global energy and trade hub into the high-stakes negotiations between the U.S. and Iran, with oil prices and shipping insurance markets beginning to reprice for long-term geopolitical premiums.

Trump's use of the term "tightly blocked" to describe the Strait of Hormuz essentially rewrites this strait from a "global public passage" to a "main battlefield and bargaining chip in U.S.-Iran negotiations." Traditionally, the U.S. has preferred to emphasize "maintaining freedom of navigation," but this time it has openly linked passage rights to negotiations, meaning that whoever controls this waterway can effectively decide who can export oil and who must undergo inspections or even be detained, significantly increasing the financial and political value of controlling the passage.
From a military structure perspective, the wording "no entry or exit without U.S. Navy approval" transforms the U.S. military from a "protector" to a "gatekeeper": it not only defends against attacks but also actively decides traffic flow. Combined with the Pentagon's previous assessment that mine-clearing could take at least months, this blockade is not a short-term tactical move but a sustainable pressure tool—allowing the U.S. to control passage speed, inspection intensity, and risk expectations without formally declaring war, thereby maintaining long-term pressure on Iran's exports and the global supply chain.
For global financial and energy markets, the consequence of this "monetization of passage" is that the Strait of Hormuz is no longer seen as a default smooth node, but rather as a bottleneck asset that requires continuous risk premium consideration. Oil futures, freight rates, and insurance pricing will no longer be sensitive only to single attacks or sanctions news but will systematically embed the time dimension of "blockade potentially lasting until a political agreement"; this forces importing countries and shipping companies to make structural adjustments in procurement strategies, inventory levels, and route selections, driving more capital towards alternative passages, backup capacities, and new energy sources.
From a broader historical perspective, this step is also accelerating the shift of the global trade order from "rules-based" to "power-based." With the U.S. openly using the Strait of Hormuz as a bargaining chip in bilateral negotiations, other countries controlling key passages (canals, straits, or railway hubs) will also be more motivated to use similar methods to obtain political or economic concessions. This means that the "low-friction, low-political-cost passages" formed in the era of globalization are being rewritten in reverse—leading to a long-term increase in the proportion of passage and security premiums in commodity prices, with the pricing power of this premium increasingly concentrated in the hands of a few countries that control chokepoints and have blue-water naval capabilities.
