【TMGM Financial Recap】Trump Labels Hormuz as "U.S. territory," Iran Shuts the Gates in Reverse, and One-fifth of the World's Oil and Gas are Stuck in the Throat

The interim memorandum of understanding reached between the US and Iran on June 17 set a 60-day negotiation window, which officially expired on August 18, with Trump stating he has no intention of extending it. At the close on August 18, Brent crude rose 2.7% to $90.87 per barrel, and WTI rose 2.6% to $84.50; in early Asian trading on August 19, WTI was at $84.12 and Brent at $91.12. But this may only be the prelude; what's even more interesting next is the still-priced transmission chain between shipping, inflation, and US Treasury yields.

Is the Strait of Hormuz "open" or "closed"?

Trump wrote on Truth Social, "There will be no talks with Iran now or in the future," and said all mines "have been cleared or detonated," and the straits are "open and operational." This narrative aims to convey to the market that "the situation is under control."

Iran's approach is completely the opposite. In his parliamentary speech, Khalibaf listed the prerequisites for reopening the strait: lifting the blockade on Iran's maritime borders, releasing frozen assets, lifting oil sanctions, and halting military threats on all fronts. Iran's Supreme Leader advisor Mokhber also stated that Tehran "remains willing to talk" but "does not confuse negotiations with surrender." From Iran's perspective, if the U.S. fails to fulfill its promises within the 60-day window, there is no reason to reopen the strait.

The contradiction between the two accounts can be partially clarified through physical evidence. Shipping data shows that on August 18, the number of vessels passing through the Strait of Hormuz remained in single digits; On the same day, the UK Maritime Trade Action Organization (UKMTO) also received a report that a vessel was struck by an unknown projectile while sailing out of the channel, damaging the engine room and causing crew casualties. In other words, official narratives may vary, but navigation has become a trickle, a fact neither side can deny.

The UAE's "Withdrawal From The Group" and Rifts in The Gulf Camp

The game is spreading from the U.S. and Iran to regional camp realignments. In the early hours of August 19, the UAE Ministry of Foreign Affairs announced the suspension of all trade, commercial, and financial transactions with Iran, citing the current escalation of the situation as "undermining regional and international peace and security." Previously, on August 18, the UAE Ministry of Defense reported that its air defense system had detected two ballistic missiles launched from Iran—one outside Iran's territorial waters and one within—but Iran has not yet responded.

Iran has not shown weakness either. The deputy commander-in-chief of Iran's Revolutionary Guard said that U.S. air power suffered significant losses, with over 200 American aircraft, including drones and manned aircraft, crashed, and accused the U.S. of considering using the "Venezuelan model" for Iran but ultimately failing to achieve its goals.

Qatar is still mediating, trying to bring both sides back to the negotiating table, but has made it clear that it is waiting for Oman and Iran to reach an agreement on the strait issue. Meanwhile, pipeline construction bypassing Hormuz has quietly accelerated: the UAE plans to build parallel pipelines alongside existing pipelines to double capacity, while the US, Iraq, and Qatar have announced upgrades to a pipeline from Iraq to Syria, while Chevron is also studying multiple pipeline plans from Iraq to Syria and Turkey. The deeper meaning of this move is that even energy-exporting countries themselves have begun preparing for the "long-term unreliability of the strait." When risk aversion shifts from temporary measures to infrastructure investment, it indicates that the market's pricing cycle for this crisis may be longer than it appears on the surface.

Oil Prices are just the Prelude: The Transmission Chain between Inflation and U.S. Treasuries

The second layer of impact on Middle East risks is not crude oil itself, but how it leverages interest rates. Rising oil prices directly boosted inflation expectations, which in turn weighed heavily on the already shaky long-term U.S. Treasuries. On August 19, the yield on the 30-year U.S. Treasury note was 5.311%, the highest since 2007. Institutions warned that if the sell-off continues, yields could further surge toward 5.60% to 5.70%.

Here's a counterintuitive point: geopolitical crises usually boost safe-haven assets and push down U.S. Treasury yields, but this time the market is selling off long-term bonds. The reason is that the Middle East deadlock is compounded by three forces—massive fiscal bond issuance, massive financing margins by AI companies, and a repricing of potential Fed rate

hike risks. If oil prices continue to stay above $90, it would further fuel the already tight inflation narrative, thereby increasing the probability that the Fed will have to become more hawkish. This conveyed chain thus formed: the strait was blocked→ oil prices rose→ inflation expectations rose→ long-term rates rose→ stocks, bonds, and currencies repriced.

What To Do Next: Two Scenarios

Scenario One (De-escalation): Mediation by Qatar and Oman facilitates partial compliance, while the U.S. signals limited asset freezes or oil sanctions, shifting the strait from "closed" to "flow restrictions," and navigation volume gradually recovers. Oil prices fell back to the $80 range, and the sell-off of U.S. Treasuries paused. The key variable in this scenario is whether Trump will truly fulfill his promise of "no extension" and whether the Oman agreement can be implemented.

Scenario Two (Escalation): Iranian officials have indicated a shift to a "full-scale offensive" military posture due to diplomatic deadlock. If more missile or mine incidents occur and navigation drops to zero, Brent could quickly surge above $100 per barrel. At that time, the transmission chain between inflation and U.S. Treasuries will be fully activated, putting pressure on risk assets.

The market currently does not fully value scenario two, which is the biggest misunderstanding. Bullish oil prices bet on supply gaps and geopolitical premiums, while bears rely on three lines of defense: "dark navigation + weak demand + OPEC production increase to support the bottom." Both logics are supported; the real outcome depends on ship traffic volume and diplomatic signals in the coming week.
