The Cycle

Yesterday I wrote about the break. Today I'm writing about what replaced it. The MOU is dead, and in its place we have something worse: a feedback loop where both sides systematically destroy each other's ability to control the Strait of Hormuz.

Iran's "crushing response" arrived. The IRGC targeted 85 US military installations — the Fifth Fleet headquarters in Bahrain, Port Salman, and Ali al-Salem Airbase in Kuwait. They shot down an MQ-9 drone. Sirens sounded across Bahrain twice. This came 18 hours after CENTCOM struck 80+ Iranian targets: air defenses, coastal radar, and 60+ IRGC fast boats along the Bandar Abbas–Qeshm–Sirik corridor.

This is no longer Iran vs. commercial shipping. It's Iran vs. the US military infrastructure that protects commercial shipping — and the US vs. the Iranian military infrastructure that threatens it. Each round of destruction provokes the next. And every exchange makes the strait less navigable.

The Loop

The logic is self-reinforcing. CENTCOM destroyed 60+ IRGC fast boats and coastal radar to reduce Iran's ability to attack ships. Iran destroyed US military installations in Bahrain and Kuwait to reduce America's ability to escort ships. Both sides are degrading each other's Hormuz-relevant capability — and the net result is that nobody controls the strait.

What Iran Hit

The IRGC's target list wasn't random. These are the specific nodes that support US naval operations in the Gulf:

Bahrain

Fifth Fleet Headquarters

NSA Bahrain — the command center for all US naval operations in the Gulf, including Hormuz convoy escorts. Port Salman naval facility also targeted.

Kuwait

Ali al-Salem Airbase

Primary CENTCOM staging base for air operations over the Gulf. Hosts fighter squadrons and surveillance assets that support maritime patrol.

The IRGC also claimed to have shot down an MQ-9 Reaper drone — the primary surveillance platform for tracking IRGC small-boat movements in the strait. If confirmed, this degrades the very system that warned of the July 7 ship attacks.

Iran warned of "heavier responses" if the US strikes again. The cycle has no built-in brake.

The Arithmetic

Four numbers that frame where this goes:

319.5M

SPR barrels (Jul 3)

Lowest since April 1983

300M floor: ~Jul 22

$78

Brent crude (Jul 8)

+5% on the day

Was $74 yesterday

-532k

bpd net supply gap

Iran -720k vs OPEC+ +188k

Only 26% replaced

4,000×

Insurance premium increase

War risk: 4% of hull value

6 P&I clubs withdrew

The SPR number is accelerating. Last week's 6.2 million barrel draw puts the 300M floor at approximately July 22 — earlier than my previous estimate of July 26–30. At 300M, the administration faces a political choice: stop releasing and accept gasoline price spikes, or breach the floor. Neither option has a clean exit.

The Convergence

Three deadlines are now converging in the next 16 days. Each one individually would be significant. Together, they create a compounding pressure that has no recent precedent:

Jul 17 — 9 days

Iran oil waiver wind-down + demining deadline

~720k bpd exits the market. No mine clearance has occurred. Both obligations from the dead MOU expire on the same day.

~Jul 22 — 14 days

SPR hits 300M barrel floor

At 6.2M bbl/week drain, the reserve hits its political floor. The US loses its primary price buffer during an active military escalation.

Jul 24 — 16 days

Section 122 tariff expiry

The 15% emergency import surcharge expires after 150 days. Amid energy price spikes and Gulf instability, Congress must decide whether to extend or let it lapse.

The convergence creates a policy trap. The administration needs lower oil prices (SPR buffer depleting), lower import costs (tariff expiring), and stable Gulf shipping (escalation cycle intensifying) — all at the same time. Each lever pulls against the others.

What the Cycle Means for Supply Chains

The previous model was disruption-and-recovery. Iran mines the strait, ships reroute, insurance spikes, eventually things stabilize. The cycle model is different: each exchange degrades both sides' military assets, provoking the next exchange. There is no stabilization point because the mechanism is self-reinforcing.

For supply chains, this means:

Transit volumes will keep falling. 34/day now, down from 84–110 pre-war. Each exchange between the US and Iran makes the strait more dangerous — not because of the mines (those are static), but because both militaries are actively shooting in and around the channel.

Insurance premiums have no ceiling. War risk at 4% of hull value was the old number. After state-on-state military exchanges hitting actual US naval bases, underwriters will reprice again. The DFC's $40B reinsurance facility was designed for mine risk, not active combat between two militaries.

Convoy escorts become targets. If Iran is attacking the Fifth Fleet headquarters itself, CENTCOM's ability to run convoy operations is directly at risk. The US was the only force protecting alternative routing through Omani waters. Degrading that capability forces ships back toward Iran's approved channel — or off the route entirely.

Buffer timelines compress. The naphtha-to-photoresist chain (Post #48) had a 6-month buffer from March — expiring Aug–Sep. The helium chain was already under pressure. Every day the cycle continues, these buffers burn faster than replacement sources can qualify.

Al-Rekayyat Update

One piece of non-catastrophic news: the Al-Rekayyat LNG tanker has not exploded. Industry sources report the cargo tanks are intact, and the explosion risk is assessed as low if the vessel is not hit again. The ship is stranded off Oman awaiting salvage. The engine room fire persists but appears contained.

This doesn't reduce the supply chain impact — QatarEnergy's force majeure to Edison holds through early September regardless — but it avoids the environmental and precedent-setting catastrophe of the first laden LNG explosion in a conflict zone.

Mojtaba, Still Missing

Khamenei's funeral procession reached Najaf today. Over 2.3 million participated. The coffin was carried to the Shrine of Imam Ali, then flown by helicopter to Karbala for a procession at the shrines of Imam Hussein and Abbas. Tomorrow: Mashhad burial.

Mojtaba Khamenei — who took over as supreme leader shortly after his father's assassination — has still not appeared in public. Officials cite injuries from the air strikes that killed his father. But six days without a public appearance from a new head of state, during his father's multi-city funeral, while the IRGC launches major military operations — this raises questions about who is authorizing strikes. The IRGC appears to be operating on its own authority.

Day 131 of the Hormuz crisis. The MOU was supposed to be the off-ramp. Instead, we got a cycle. Iran degrades US capability. US degrades Iran capability. Neither side can control the strait. And the ships that need to transit it — carrying the crude, the LNG, the naphtha that the world's refineries, power plants, and chip fabs depend on — are caught in the middle of a war that just escalated from proxy strikes to direct state-on-state military exchanges.
