**Summary**: Trump reiterates that the US will maintain a blockade affecting Iranian ports via the Strait of Hormuz, while CENTCOM reports it has redirected 121 commercial vessels and disabled five since mid‑April. Concurrently, IRGC fast attack boats are shown patrolling the strait, underscoring elevated risk of miscalculation and further disruption to Gulf shipping.

## Detail

Several reports in the last hour point to a hardening of the de facto blockade environment around Iranian ports and elevated militarization of the Strait of Hormuz. Trump stated in an NBC interview that the US will "keep the blockade" in place, characterizing it as "a piece of steel," and suggested he can "wait as long as [Iran] want" economically, framing Iran as "losing a fortune." CENTCOM separately indicated that since the April 13 start of the blockade of Iranian ports, US forces have redirected 121 commercial vessels and disabled five. In parallel, open‑source imagery and reporting show IRGC Navy fast attack boats actively patrolling the Strait of Hormuz, armed with rocket launchers and heavy machine guns.

What this signals is not a new closure event—global oil flows through Hormuz are still moving—but a sustained, high‑friction operating environment for shipping linked to Iran and heightened risk of an incident involving US and Iranian forces. The scale of redirections (121 vessels) and disabling actions (5) since mid‑April implies material disruption specifically to Iranian export and import flows, especially oil, condensate, petrochemicals, and general cargo destined for or originating from Iranian ports.

For global markets, the immediate physical loss of supply is limited mainly to constrained Iranian exports, which had been running above formally sanctioned levels. However, the persistence and public framing of a long‑term "blockade" materially lifts the geopolitical risk premium embedded in:
- Brent and WTI crude (bullish bias), given that roughly 17–20 mb/d of crude and condensate normally transit Hormuz.
- Dubai/Oman benchmarks and Middle East sour crude differentials, as regional producers face higher insurance and routing risk.
- Spot and forward freight rates for VLCCs and product tankers in AG–Asia/Europe routes, as shipowners price in war‑risk premiums and potential delays.

Historically, periods of acute Hormuz tension (e.g., 2019 tanker incidents, 2011–2012 sanctions ramp) have reliably produced >1–3% swings in oil benchmarks on escalation headlines. The combination of an open‑ended US "blockade" posture, Iranian threats over Hormuz in earlier reports (already reflected in existing alerts), and visible IRGC patrols raises the probability of a miscalculation or targeted interdiction that could temporarily curtail broader Gulf flows.

Duration: as framed by Trump, the blockade is intended to be enduring rather than transient, implying a structural uplift in Middle East oil risk premia for as long as the standoff continues.
