The United States military carried out a second consecutive night of strikes against Iran, following a drone attack on a commercial ship in the Strait of Hormuz on Saturday that American officials attributed to Iran.
The Strait of Hormuz is one of the world's most critical energy chokepoints. Roughly 20 percent of global oil and liquefied natural gas passes through this narrow waterway between Iran and Oman. Any sustained disruption there ripples quickly into energy prices worldwide, and by extension into the cost of fuel, goods transport, and manufacturing across major economies.
A commercial vessel was struck by a drone in the strait on Saturday. The United States attributed the attack to Iran. That incident followed the first night of US strikes, suggesting Washington has adopted a sequential response posture rather than a single retaliatory action. The back-to-back nature of the strikes signals a deliberate escalation in US military engagement with Iran, though the specific targets, scale, and outcomes of the second night of strikes were not detailed in available reporting.
The pattern matters: two consecutive nights of strikes represent a sustained military operation, not a one-off response. That distinction shifts how markets, allies, and regional actors read American intent going forward.
The Strait of Hormuz has no easy alternative for most Gulf oil exporters. Saudi Arabia, Iraq, the UAE, Kuwait, and Qatar all rely on it to move crude and gas to buyers in Asia and Europe. A scenario in which shipping insurers reprice risk, tanker operators reroute or pause voyages, or Iran moves to physically contest the strait would tighten global oil supply at a moment when energy markets are already sensitive to geopolitical signals.
Even without a full blockade, the threat premium alone tends to push oil futures higher. Higher crude prices feed through to petrol costs, airline fuel surcharges, and freight rates, affecting consumers and businesses well beyond the immediate conflict zone. Indian refiners, who source a significant share of crude from Gulf producers and have historically bought discounted Iranian oil, are particularly exposed to any sustained disruption in Hormuz traffic.
The commercial shipping sector faces a related but distinct pressure. Since the Houthi attacks on Red Sea shipping that began in late 2023, global maritime insurers have raised war-risk premiums sharply and operators have rerouted vessels around the Cape of Good Hope, adding weeks and cost to voyages. A concurrent escalation in the Strait of Hormuz would compound that pressure significantly, with fewer geographic alternatives available for Gulf energy exports.
Iran's drone and missile capability in the region has been demonstrated repeatedly over the past two years, both through direct actions and through proxies. The attribution of Saturday's ship strike to Iran directly, rather than to a proxy group, raises the diplomatic and military stakes of the US response and narrows the space for de-escalation through back-channel negotiation.
The second night of US strikes also carries implications for ongoing international efforts around Iran's nuclear programme. Military exchanges of this kind tend to harden positions on both sides and reduce the near-term prospect of a negotiated agreement, which in turn keeps sanctions architecture in place and Iranian oil supply constrained from fully entering global markets.
What to watch next: whether Iran responds to the US strikes with further drone or missile activity in the strait or elsewhere in the region, how global oil futures open in the coming sessions, whether the US announces specific targets or battle damage assessments, and whether Gulf states or European governments issue formal positions on the escalation. Any Iranian move to threaten or block commercial transit through Hormuz would trigger an immediate and sharp market reaction.
Iran has attacked Kuwait and Bahrain in retaliation for US strikes, drawing two key Gulf US allies into the conflict. The escalation puts a reported US-Iran deal under serious strain and raises energy supply risk in a major oil-producing region.
Iran's Revolutionary Guards have warned that oil tankers crossing the Strait of Hormuz without authorisation risk being stopped, even as one tanker proceeded through the waterway. The threat could push up war-risk insurance premiums and crude prices, with major importers like India directly exposed.
Iran and the US traded fresh strikes over the Strait of Hormuz, with Tehran hitting US bases in Bahrain and Kuwait and Washington striking Iranian sites near Sirik. The exchanges threaten to collapse a Pakistan-brokered ceasefire signed June 18, with global oil markets exposed to renewed Hormuz disruption.
Iran's IRGC struck US military facilities in Kuwait and Bahrain on Sunday for a third straight day, while Trump threatened Iran would "no longer exist" if the US resumes full war.
