Tehran Says It Will Tighten the Closure and Names American Voters as the Pressure Point

Mohammad Bagher Zolqadr, secretary of Iran’s Supreme National Security Council, said on Friday that Tehran would tighten its declared closure of the Strait of Hormuz in response to what he described as a US naval blockade of shipping to and from Iranian ports. Press TV quoted him warning that a prolonged American adversarial approach would “not only … further complicate the closure of the waterway, but also close other straits and chokepoints,” and that “the global economy, energy markets, and American voters will pay the price.” The second sentence is the more useful one: it states the Iranian theory of victory as a domestic American fuel-price problem rather than a military one. Separately, the Persian Gulf Strait Authority, the Iranian body created during this crisis, maintains that passage is not possible and that transit permits are obtainable only through its website.

The UK Maritime Trade Operations centre reported that an unnamed tanker was struck roughly 12 miles northeast of Lima, Oman, on the southern side of the strait, and was reported “not under command” with no casualties. UKMTO did not attribute responsibility. On 30 July the IRGC had claimed via Press TV that two tankers attempted to exit by the “unsafe southern route” after being prompted by US aircraft, that one caught fire and both reversed course; the Guards said “the Strait of Hormuz is our territory, and the brave men of the IRGC Navy firmly control it.” Lloyd’s List Intelligence counted 78 transits between 13 and 19 July, against 174 in the prior comparable period, per USNI News. Brent averaged $82.60 through July, with a $70.14 low and a $95.30 high, up 20.35 per cent on the month, according to Investing.com.

CNN, reporting Friday, said traffic has been cut from a pre-war level of around 130 ships a day “to only a handful now.” A Trading Economics market wrap the same day said tanker traffic through the strait had increased after a recent slowdown, allowing millions of barrels of crude to pass. NBC News’s tracker puts the pre-war baseline at “a hundred-plus ships a day” and the strait’s historic share at about 20 per cent of the world’s oil and natural gas; the straits.live aggregator uses roughly 88 a day. Three baselines are in circulation, which is enough on its own to make any percentage-drop claim unfalsifiable.

Assessment: The closure is now measured in permits and press releases rather than hulls, which suits Tehran: an authority that issues transit documents online converts a military inability to seal a waterway into an administrative claim to control it. Distrust the volume numbers in both directions — the security desks are counting what is not moving, the commodity desks are counting what got through, and dark-fleet movements sit outside both. The market is the honest witness. A July that ranged from $70 to $95 and closed in the high $80s is pricing attrition, not catastrophe, which is precisely what Zolqadr’s appeal to American voters needs to change.
