**Deck**: Iran’s parliamentary speaker says Tehran will give a military response if the United States intensifies its blockade and prevents Iranian oil exports, vowing that in that case other Persian Gulf shipments will also stop. With U.S. forces redirecting 84 vessels and Washington preparing new bank sanctions, the standoff over the Strait of Hormuz is deepening.

Iran is tying its response to mounting U.S. pressure directly to the flow of oil from the Persian Gulf, warning that if its own exports are blocked, others will be too.

Mohammad Ghalibaf, the speaker of Iran’s parliament, has issued a series of statements as U.S. forces redirect 84 vessels under what Washington describes as an Iran blockade and prepare further economic sanctions. He says that if the United States tightens the siege or fails to honor its commitments under a memorandum, Iran will answer militarily and use what he calls the "language of power". In that scenario, Ghalibaf warns, if Iran cannot export oil from the Persian Gulf, no one will be able to export oil from the region.

Ghalibaf also claims that Iran’s armed forces have full control over the Strait of Hormuz and accuses the United States of trying to move only a few ships through a southern route in violation of an agreement. He says that before the current war at least 120 ships passed through the strait daily, whereas now only one or two do so — figures that cannot be independently verified here but that underscore Tehran’s message that it sees the strait as a pressure tool.

On the U.S. side, Iran envoy Scott Bessent has set out a strategy of escalating financial pressure. He says Washington is likely to announce a bank sanction this week and another the week after, portraying them as part of a campaign to convince Iran’s leadership that it must return to negotiations after a previous memorandum of understanding failed. Bessent argues that Iran’s rulers have mismanaged a country with some of the world’s largest energy resources and says his job is to make them want a deal.

The clash is unfolding around the Strait of Hormuz, the narrow waterway that connects the Persian Gulf to global sea lanes and carries oil exports from Iran and its Gulf neighbors. Even without an officially declared blockade, U.S. naval maneuvering and Iranian rhetoric about closing the route raise the risk that miscalculation could spill over into actual interference with shipping.

For ordinary Iranians, tighter U.S. maritime and financial measures mean further pressure on a sanctions‑hit economy that relies heavily on oil revenues. Yet any decision by Tehran to obstruct other countries’ exports would invite direct retaliation and increase the chance that Iranian ports, refineries and coastal infrastructure become targets.

Globally, the stakes are straightforward. The more credible Iran’s threats appear and the more extensive U.S. and allied naval operations become, the higher the perceived risk premium on oil moving through the region. That in turn can affect energy prices, insurance costs and the willingness of shipowners to transit the strait.

What would change the trajectory is clear: concrete evidence that Iran has begun to interfere with non‑Iranian tankers, a formal U.S. move to declare or deny that its actions amount to a blockade, or a shift by major Asian importers in their diplomatic stance if their supplies are jeopardized. Any high‑profile seizure or sinking of a large exporter’s vessel would move the confrontation from words and sanctions into an overt crisis.
