TL;DR: Three American partners signed a mutual defence pact during an American war in their region, and the United States is not a party to it. Separately, the two countries that border the Strait of Hormuz are finalizing an agreement to administer it, and the United States is not in that clause either. When the president was asked about the talks, he threatened to bomb Oman. The guarantee that kept the Gulf open for nearly half a century is no longer sufficient on its own, and the customers are hedging.
The guarantee
For nearly half a century, the United States treated open navigation through the Persian Gulf as a vital interest and backed that promise with military power. It maintained a fleet in the Gulf, and when tankers needed protection, the security architecture provided it. A ship did not have to negotiate an individual transit fee with Washington in order to sail. Every country that moved oil, gas, fertiliser or containers through that water benefited, whether or not it was an American ally. It was efficient the way a public utility is efficient: one provider, universal service, the cost absorbed by the provider because the provider needed what the water carried.
That arrangement worked because it was cheaper than the alternative. No Gulf state needed its own escort capability. No Asian importer needed to negotiate passage with a militia. No insurer needed to draft a clause for a fee that could not legally be paid. The guarantee was a product, and for nearly fifty years the product delivered.
Five and a half months into the Iran war, it is no longer sufficient. The Navy's own chief told Congress in May that escort at scale would exceed the fleet's capacity without a ceasefire. One convoy operation was attempted, covered two ships in three days, and has not been repeated. The carrier operates from the Arabian Sea. The fleet headquarters sits inside the Gulf absorbing missiles, resupplied from 2,200 miles away. A forty-billion-dollar government insurance programme, built as the credential for a Navy convoy, has never publicly issued a policy, because the convoy stopped running on 7 May.
When a product is no longer sufficient on its own, customers do not wait. They shop.
What they are building
On Friday 7 August, Crown Prince Mohammed bin Salman, President Erdoğan and Prime Minister Sharif signed a mutual defence agreement at al-Safa Palace in Mecca. The clause that matters: "any armed attack against any one of the three States shall be regarded as an attack against them all." Turkey's foreign minister Hakan Fidan called the principle technically comparable to NATO's Article 5, and said the three would form political and military committees and a permanent secretariat, to be based in Saudi Arabia. The full text has not been released.
The combined capability: roughly 1.4 million active military personnel and $124 billion in annual defence spending. Turkey has NATO's second-largest military. Pakistan is the only Muslim-majority nuclear-armed state. No integrated command structure or joint exercises exist yet.
What the pact is for is contested on the wire itself, and we will not settle it for you. Turkey says it is not aimed at Iran. The Straits Times calls it a hedge against the limits of American defence. Trump praised it. Pakistan's foreign minister spoke directly to Iran's Araghchi about it afterward; Iran's own state media called it "a threat or an opportunity?" DW and Foreign Policy both treat the target question as the central open one. Egypt may be joining. We report the capability fact and the contested readings side by side.
What is not contested: three American partners signed a mutual defence treaty during an American war in their region, and the guarantor is not a party to it.
The same weekend, the second structure appeared. Iran's foreign ministry announced that Tehran and Oman had reached an understanding and were drafting a joint declaration on navigation through the strait. The Islamabad memorandum's fifth point assigns the strait's future administration to Iran, Oman and the Gulf littoral states. The United States is not in that clause. Oman put a management proposal to Tehran on 28 July; Reuters reported on 6 August that the same proposal would give Tehran control over ships entering the Gulf, with shipping associations calling it a toll in all but name. Iran's foreign minister said the talks concerned a temporary navigation route only.
This is Tehran's account and not yet Muscat's. We print it attributed and watch for confirmation.
Two straits, two permission regimes
The guarantee used to cover two waterways with one navy. It no longer covers either.
At Bab al-Mandeb, the Houthis now clear individual vessels for transit. On 24 July, Lloyd's List reported two Cosco VLCCs transiting after securing Houthi clearance, hull by hull. On 1 August the Houthis denied planning to charge vessels for Red Sea passage, the same week ship traffic through the strait dropped sharply. The pattern is analogous to Hormuz: no published fee, mandatory permission, and a denial that any fee is planned. On 29 July Saudi Arabia began seeking its own international coalition to protect Red Sea shipping from the Houthis, separately from any American-led effort. A cargo ship was in flames after a Houthi attack in the strait on 11 August, killing four crew members.
Where one navy kept both waterways open, each now requires its own arrangement, its own clearance, its own coalition. That is the efficiency argument measured in hulls.
The guarantor's response
On 14 August, at a rally in New York, the president said he would soon declare the Strait of Hormuz a territory of the United States. He chuckled. Then he said it was true. A senior White House official told a reporter he had been joking. The Navy blockade behind the remark kept running unchanged.
On 17 August, asked on Fox News about the Iran-Oman shipping talks, he said: "If Oman gets in the way, we'll bomb the shit out of them." He said Iran should "put up the white flag of surrender." He said he had no time schedule and was not in a hurry.
Oman is the country that has hosted the American backchannel with Tehran throughout this war. It is the co-designer of the navigation framework for the strait. Its waters form half the channel. It is now subject to bombing threats from the country whose security architecture had made such an independent arrangement unnecessary for decades.
What we owe you
Four items from previous issues that we have not delivered.
On 26 July we pre-registered a test at the Malacca Strait and said we would publish the outcome either way. On 4 August the print came in at 93 percent of baseline, inside the 92 to 95 percent band we named for "moving unseen." The oil did not stop; it went dark. The 9 August print was 87.3 percent, between our two bands, and we report both because passing a test does not entitle us to hide a number that is moving.
On 9 August we told you that whether ships start paying to pass was about to become observable. It was not. No tariff was published, the strait authority has never issued a fee schedule, and paying was already sanctionable under American law before any price existed. We were wrong that the deadline would make the mechanism observable.
On 19 July we called the Senate's deadline for the Pentagon's Minab investigation "the closest thing to an acknowledgment test this war has produced." Our July issue put the toll at 156 killed including 120 students; Iranian media this week reported 168 students killed, which may reflect an updated count. The Senate deadline expired unmet on 20 July. We mentioned it once, in a line in our 26 July issue, and have been silent for three issues since. As of 15 August, Iranian media counted 168 days of international silence on Minab. The investigation has not been released, classified or acknowledged.
Correction. Our 14 June issue stated that roughly 172 million barrels had been drawn down from the Strategic Petroleum Reserve. That figure was the IEA and US release pledge, not the actual drawdown, which was about 110 million barrels. Our 7 June issue correctly distinguished the two, and our 9 August issue gave the actual levels. We printed the target as the fact, and we are noting the error here, which is what we do when we get something wrong.
What we are watching
These structures produce concrete results or they were announcements. The Mecca Pact produces joint exercises, a command structure, and defence cooperation, or it was a communiqué. The Iran-Oman declaration produces pilings, buoys, a salvage service, a published tariff, or it was a photo opportunity. We will report either outcome.
The standing test from 2 August holds: an American-escorted convoy transits the strait and the war-risk premium falls.
General License X, Treasury's 60-day Iranian oil waiver, expires around 21 August. The first SPR return window opens 1 September.
