Hormuz Watch: Week 16

The Setup

Last week, in Week 15, the thesis was that the war's cost had detached from its price. Oil was falling on deal hopes while consumer inflation hit a three-year high, wholesale inflation hit 6.5%, and the European Central Bank raised rates. We called it the bill coming due. We also laid out the scenario that would end the crisis: the deal the president kept describing as imminent actually getting signed. This week, it did.

Late Wednesday, at the Palace of Versailles, President Trump and Iranian President Masoud Pezeshkian signed an interim memorandum of understanding. It takes effect immediately, calls for a permanent end to hostilities, reopens the Strait of Hormuz, lifts the US naval blockade, waives sanctions on Iranian oil, and commits Iran to diluting its stockpile of highly enriched uranium. It starts a 60-day clock to negotiate a final deal on the nuclear program. The International Atomic Energy Agency says it is ready to begin implementation. After fifteen weeks and more deal promises than anyone could count, there is a signature.

The market response was immediate and large. Brent crude fell below $78 a barrel, the lowest since early March. Gas fell below $4. The premium that the war had injected into oil prices, which we have tracked all month, has nearly fully unwound. By every real-time signal, the crisis is ending.

And then, the same afternoon, the Federal Reserve did the opposite of what an ending crisis would suggest. It held rates, but it removed the rate cut it had penciled in for 2026 and signaled that its next move could be a hike. That is the tension that defines this week, and it is not a contradiction. It is the whole point. The thing that caused the inflation, the closed strait, is being fixed. The inflation itself is already in the system, and you do not un-print a three-year-high CPI by signing a treaty. So we start with the board, because the board now tells two stories at once.

The Dashboard

Five metrics. This week, four of them eased as the war wound down, and the fifth, the Fed, tightened. That split is the single most important thing on the dashboard right now.

1. Oil's Fear Gauge

The crude oil volatility index, the options market's forecast of how much oil will move over the next month, eased as the signing removed the single largest source of uncertainty hanging over the market. It is coming down off the low 60s where it sat for weeks, still well above its calm-market floor near 23, but a long way from the panic peaks near 108 to 126 it reached in the opening weeks of the war. A signed deal is, by definition, less uncertain than an unsigned one. The gauge is telling you the market believes that.

2. Brent and the Risk Premium

Brent settled below $78 this week and US crude near $75, both the lowest since early March, and oil is now down roughly 38% from its April peak above $126. Against a no-conflict baseline near $60 to $65, the war premium has compressed to roughly $13 to $18 a barrel, down from the $25 to $30 we tracked last week and the $30 to $35 the week before. The premium is not gone, but it is going. The most striking shift is in the forecasts: the International Energy Agency, which spent the spring warning about shortage, now warns about a glut, projecting global supply could rise by 8 million barrels a day in 2027 against demand growth of only 2 million. The market has flipped from pricing scarcity to pricing surplus. The one caution sign is inventory: stockpiles at the Cushing hub have fallen to around 20 million barrels, near operational minimums, so the physical cushion is thin even as the price falls.

3. The Physical Regime

The water is reopening, partially and unevenly, which is the most dramatic change on the board. The main central route through the strait is still closed, with an estimated 80 sea mines that need to be cleared. But the northern route through Iranian waters and the southern route through Omani waters now appear fully open, and at least ten commercial vessels transited after the signing. The blockade of Iranian ports has been lifted. Lloyd's List estimates roughly 550 merchant ships are queued to exit the Gulf, including 160 tankers. The honest framing is that the strait is going from essentially closed to partially open, and industry officials caution that fully restoring Iranian production and the normal flow of traffic could take weeks, months, or longer. The mines do not clear themselves.

4. Gas

The national average fell to $3.999 this week, dropping below $4 for the first time since late March, the fourth straight weekly decline from the $4.56 peak on May 21. The round number matters more for sentiment than for any household budget, and the relief is real heading into a record July 4th travel week. But keep the rear-view mirror in view: pump prices are still roughly 25% higher than a year ago, and the May inflation data that printed last week, showing gasoline up more than 40% year over year, is the cost this decline is only beginning to walk back.

5. The Fed

This is the metric that moved the other way. The Federal Open Market Committee held the funds rate at 3.50% to 3.75% in a unanimous 12-0 vote at Kevin Warsh's first meeting as chair. But the projections turned hawkish: the committee removed the rate cut it had penciled in for 2026, and nine of eighteen officials now project a hike before year-end, with six seeing two. They raised their inflation projection for year-end to 3.6%, up from 2.7% in March, and cut their growth forecast. Markets now price a 60.7% chance of a hike by October. Warsh declined to submit his own dot and announced five review task forces, but the message on inflation was blunt: the commitment to the 2% target, he said, is the left of the decimal point, and for now zero is to the right of it. While every other metric on this board relaxed, the central bank did not.

Signed, Not Solved

A signature is not a settlement, and the gap between the two is where the next phase of this story lives. The agreement signed at Versailles is an interim memorandum, not a final treaty. It buys 60 days to negotiate the hardest part, the future of Iran's nuclear program, which is the issue that started the confrontation and the one most likely to break it. The deal commits Iran to diluting its enriched uranium, but the IAEA spent the spring warning it could no longer fully verify that stockpile. The verification is the deal. Words on paper at Versailles do not dilute a single gram.

The physical reality is just as unfinished. The central shipping channel remains mined. Roughly 550 ships are waiting to move through routes that only partially reopened this week. And the president was explicit that the agreement holds only as long as Iran complies, telling reporters he would resume strikes, in his words, if Tehran violates the terms. So the structure of the next two months is a fragile interim deal, a mined waterway, a 60-day negotiating clock on the thorniest issue, and a standing threat to restart the war if it slips. That is meaningfully better than an active conflict. It is not the same as resolution.

This matters for one practical reason: the oil market has already priced the optimistic version. At a three-month low with the IEA now forecasting a surplus, crude is trading as though the deal not only signed but succeeded. That makes the risk asymmetric, and we will come back to that.

Why the Fed Didn't Blink

On the surface, the Fed's hawkish turn looks like odd timing. The war is ending, oil is collapsing, and gas is below $4. Why would a central bank lean toward hikes into falling energy prices? Because the Fed is not looking at the price of oil today. It is looking at inflation that has already happened and is still working its way through the economy.

The numbers it is staring at are the ones from last week: consumer inflation at a three-year high of 4.2%, wholesale inflation at 6.5%, with the pipeline of producer costs still rising. Those are facts on the ground, not forecasts. A falling oil price in June does not reverse a price level that climbed all spring; it slows the rate of future increases. The Fed's job is the price level and inflation expectations, and on both, the war already did its damage. Cutting rates into that, on the strength of an interim deal and a mined strait, would be a bet that the inflation has peaked. This committee was not willing to make that bet, and its projection that inflation ends the year at 3.6% says it expects the elevated readings to persist.

There is a second message in the hawkish dot plot, and it is about credibility. The Fed has missed its 2% target for five years. Warsh's framing, that the commitment to 2% is non-negotiable and that the institution intends to deliver on it, is a signal that the new chair would rather risk over-tightening than let a supply-driven inflation spike get embedded in expectations. The European Central Bank made the same choice last week when it became the first major central bank to hike into this shock. The Fed did not move rates this week, but its projections moved its peers' direction. The era of the market pricing the next cut is, for now, over.

What Would Break the Regime

For fifteen weeks this section weighed escalation against resolution. This week resolution arrived, which changes the analysis: the market has priced the good outcome, so the balance of risk has flipped to the upside on oil.

It breaks upward if the deal does not hold. The triggers are specific and live: the 60-day nuclear negotiation fails, Iran is found to be slow-walking the uranium dilution the IAEA cannot yet verify, mine clearing on the central route stalls, or the president follows through on his threat to resume strikes after a violation. Any of those would re-inject a premium into a market that has just removed almost all of it, and because oil is sitting at a three-month low with thin inventories at Cushing, the move up could be fast. The downside protection that a high premium provides is gone. This is the scenario to respect precisely because the market has stopped pricing it.

It breaks further downward if the deal not only holds but works. If the mines clear, the central route reopens, and Saudi, Emirati, and Iraqi barrels that were held back come flooding out alongside restored Iranian output, the IEA's surplus scenario takes over. Brent drifts toward the low $60s, gas heads toward $3.50 by late summer, and the inflation impulse from energy reverses, eventually giving the Fed room to revisit the cuts it just erased. This is the genuinely benign path, and it is plausible. It is also slow: even in the best case, normalizing the flow of oil through a mined strait is a matter of months.

The base case is a messy, partial normalization. The most probable path is neither a clean success nor a collapse: the interim deal mostly holds, the strait reopens in stages, oil settles into the $70s, gas keeps drifting lower, and the inflation already in the pipeline recedes slowly while the Fed stays cautious and data-dependent into the fall. In that world, the crisis phase of this story is ending, but the cost phase, measured in the inflation data and the Fed's response to it, runs for months yet.

The Bottom Line

Sixteen weeks ago this column started tracking a crisis almost nobody was pricing. This week, a deal to end it was signed at Versailles, oil fell to a three-month low, gas dropped below $4, and the strait began, partially, to reopen. By the measures that move fastest, the war is ending, and that is real and worth saying plainly. But the same afternoon the deal was signed, the Federal Reserve erased its rate cut and penciled in a hike, because the inflation this war created is already in the data and does not care that the shooting has mostly stopped. The war's price, traded on screens, is collapsing. The war's cost, paid in a higher price level and a more hawkish central bank, is still being collected.

This may be the beginning of the end of this series, or it may be one more false dawn in a conflict that has produced several. An interim deal is not a treaty, a mined strait is not an open one, and a 60-day clock on the nuclear question is exactly the kind of deadline this story has blown through before. So the watch continues, but the thing to watch has changed. For months it was whether the crisis would get worse. Now it is whether the deal holds, whether the mines clear, and how long the inflation already on the books takes to fade. Watch the 60-day clock, watch Cushing, and watch the Fed. The price will tell you what the market hopes. The data will keep telling you what the war actually cost. Data over narrative. Always.
