Tehran Threatens Gulf Shipping as US Says Hardest Hits on Iran Are Yet to Come

The ongoing conflict between the United States, Israel and Iran has taken a dangerous turn for global maritime trade after Tehran issued fresh threats to commercial shipping in the Gulf, warning that vessels traversing the Strait of Hormuz could face attack as Iran intensifies its response to recent Western military strikes. At the same time, senior US military officials have signalled that the “hardest hits” against Iran’s military infrastructure are still to come, suggesting further escalation before the campaign subsides.

In the face of mounting pressure, Iran’s Islamic Revolutionary Guard Corps (IRGC) has effectively challenged passage through the Gulf’s crucial maritime chokepoint. The Strait of Hormuz — which handles about 20 percent of the world’s oil exports — has seen commercial shipping grind to a near standstill after Iran declared navigation closed, broadcasting warnings that restrictions on vessel movement could be enforced if perceived security threats persist.

Data from international shipping sources indicates that hundreds of tankers and cargo vessels have dropped anchor in anchorages around the Gulf and adjacent waters, reluctant to risk transiting the strait amid escalating hostilities. Dozens more remain stationary near ports in the United Arab Emirates, Saudi Arabia and Qatar as insurers suspend war-risk coverage and carriers reroute services via the longer Cape of Good Hope route — a detour that adds significant cost and time to global freight movements.

Iran’s maritime warnings come in the wake of a broad Iranian missile and drone campaign targeting U.S. and allied military positions across the Gulf region in retaliation for U.S. and Israeli strikes that included the killing of Iran’s supreme leader. Maritime risk indicators have surged, with analysts noting damage to multiple commercial tankers and at least one seafarer killed as vessels have been caught in the conflict’s expanding footprint near the Strait of Hormuz.

The United States, while continuing to urge caution among commercial operators, has taken a more aggressive military posture. Long-range bomber missions and sustained strikes on Iranian missile and military infrastructure are ongoing, with U.S. Central Command officials telling reporters that the most severe phase of the campaign against Iranian capabilities has not yet occurred. This language, used by military spokespeople to describe the coming operations, reflects expectations of intensified pressure aimed at degrading Tehran’s capacity to project force across the Gulf and against U.S. assets.

The dual message — Iranian threats to shipping juxtaposed with U.S. warnings of further strikes — has heightened uncertainty for global energy markets and supply chains. Traders have responded with volatility; crude oil benchmarks have spiked as flows through the Hormuz corridor remain disrupted, and logistics planners cite severe challenges as container and energy cargos are forced onto lengthier routes or delayed by congestion and security concerns.

International governments and maritime organisations have issued guidance urging non-essential shipping to avoid the Gulf region. The UK Maritime Trade Operations and other naval information centres have reiterated the risks of transiting contested waters amid electronic interference, missile activity and navigational hazards. Although Iran’s threat has not been universally recognised as a formal blockade under international law, the practical effect — a de-facto reduction in vessel movements — is reshaping global shipping patterns.

Energy industry analysts warn that prolonged tensions could constrain oil and liquefied natural gas exports for weeks or months, potentially pushing prices higher and triggering broader economic repercussions. The global economy’s reliance on uninterrupted flows through the Strait of Hormuz underscores the far-reaching consequences of the regional conflict — extending well beyond battlefield dynamics to influence trade, inflation and geopolitical risk perceptions worldwide.
