Hormuz Is Shooting Again. Friday's Progress Did Not Hold.
U.S. and Iranian forces exchanged attacks around the Strait of Hormuz for the first time in a month, and Washington is considering recurring limited strikes to suppress rebuilt Iranian anti-ship capabilities. Brent settled above $90, the 10-year yield held near 4.75% and September Fed-hike odds rose to 66%, keeping the pulse at RED despite contained equity losses and low volatility.
Friday’s route-repair story lasted one weekend.
U.S. forces struck two Iranian launchers on Larak Island after officials said Iranian crews were preparing rockets capable of deploying sea mines into the Strait of Hormuz. Iran said it retaliated against U.S. sites in Jordan. The UAE then intercepted an Iranian drone over its waters. This is the first significant U.S.-Iran exchange in a month, and it lands directly on the shipping route that had just started to look safer.
Brent crude rose about 3.4% to $91.10, reversing much of last week’s relief. U.S. crude traded near $86.40. The national gasoline average has spent all of August above $4, so another oil spike would reach consumers who are already tired of paying for this war.
The market reaction is cautious, not disorderly. SPY was down about 0.5% near $765.60 this morning. The S&P 500 opened 0.18% lower, and the Nasdaq opened 0.17% lower. That is a controlled response near record levels, but it comes after Nvidia fell 4.6% Friday and weaker breadth exposed how much of the index cushion still rests on a few large AI names.
Bonds are the harder problem. The 10-year Treasury yield rose to roughly 4.75% after Kevin Warsh’s Jackson Hole speech pushed the estimated chance of a September hike to nearly 60%. July PCE inflation is running at 3.7% year over year. Oil above $90 gives the Fed another reason to stay restrictive just as hiring slows.
Layoffs remain rare. Initial claims fell to 203,000 last week. Hiring is much less comfortable: forecasters expect Friday’s payroll report to show only 45,000 to 65,000 new jobs after July lost 23,000. Tuesday’s JOLTS report and Friday’s employment report now carry more weight because the Fed is openly considering a hike into a softening labor market.
Households are still spending, but the cushion is thinning. August consumer confidence fell to 89.4, its lowest level in seven months, and July retail sales posted their first decline in nine months. Higher gasoline prices, tariffs and a weak hiring outlook are hitting sentiment before they produce a broad layoff cycle.
Trade policy is adding pressure. Canada begins counter-tariffs on September 8, while the latest U.S. tariffs on Canada already face legal questions. Treasury Secretary Scott Bessent heads into the G20 asking allies to help isolate Iran while U.S. trade policy has strained many of those same relationships. China reported another month of manufacturing contraction, despite stronger export demand.
I found no new DOGE action that changes today’s deployment call. The more relevant fiscal fact is that government borrowing is already demanding a higher yield. The GAO also says large parts of DOGE’s claimed savings remain unsupported, so I would not count those figures as a serious offset to the debt premium.
Elsewhere, Russia’s drone barrage around Kyiv has entered a fifth day and Taiwan says China is tightening air and sea control around the island. Both matter. Neither is setting today’s price. Hormuz, oil and the Fed are.
Historical context: 1973 Yom Kippur War / oil embargo
This is one possible analog, not a forecast.
Similarities:
- A Middle East war is disrupting an important oil channel and raising consumer energy costs.
- The inflation shock is constraining the Fed while confidence and hiring weaken.
- Markets keep trying to price route repair before the political and economic damage is settled.
Differences:
- The United States is less dependent on imported energy than it was in 1973, which reduces the domestic growth hit.
- Today’s disruption comes from attacks, mines and armed transit rather than a unified producer embargo.
- Protected shipping is still moving some oil, layoffs are rare, and equity volatility remains subdued. Those are better conditions than the analog.
- Valuations and long-duration equity exposure are much higher today, which increases sensitivity to yields and Fed policy.
| Strategy | Typical 5M Return | Typical 5M Vol | Analog Return | Analog Max DD | Analog Vol |
|---|---|---|---|---|---|
| Buy & Hold | +4.5% | 13.3% | -11.0% | -18.6% | 19.6% |
| 200 SMA Trend | +1.8% | 10.7% | -4.5% | -5.5% | 5.6% |
| 12M Momentum | +2.8% | 11.3% | +0.0% | 0.0% | 0.0% |
| RSI Mean Reversion | +0.0% | 5.8% | -2.8% | -10.1% | 17.6% |
The analog’s useful warning is that oil relief can reverse before inflation and confidence recover. Today’s economy has more protection from the energy shock, and the market is nowhere near the disorder of 1973. But Friday’s improvement did not survive its first military test. Trend discipline mattered in the analog, and it matters now.
Deployment stance
The pulse stays RED. Keep exposure reduced or explicitly hedged.
Orderly equities, low claims and partial protected shipping argue against CRITICAL. Renewed U.S.-Iran fighting at the route itself, Brent above $91, a 4.75% 10-year yield and a hawkish Fed argue against YELLOW.
I would move to YELLOW if the exchange stops, protected commercial traffic continues, Brent falls below $85 and long yields ease. I would move to CRITICAL if attacks close the protected corridor, Brent clears $95, or the shock spreads into VIX above 20 with a broad equity and credit break.
The next catalysts are JOLTS on September 1, the August employment report on September 4, Canada’s counter-tariffs on September 8, August CPI on September 11, and the Fed decision on September 16.
Post-close update
The market contained the first exchange. The policy response is becoming the bigger risk.
The S&P 500 closed down 0.3%, the Dow lost 0.7%, and the Nasdaq slipped 0.1%. Nearly every S&P sector fell, but the indexes still finished August with gains. Brent settled 2.7% higher at $90.49, below its morning high but firmly back above the level that keeps the inflation channel active. The 10-year Treasury yield finished around 4.75%.
That is not a panic tape. It is also not relief. Fed-funds pricing moved to a 66% chance of a September hike, up from roughly 58% after Friday’s speech. The bond market is treating renewed oil pressure as a policy problem even while stocks are treating it as a manageable military event.
The new development after the morning pulse is that the White House is considering a CENTCOM plan for recurring limited strikes against rebuilt Iranian radar, air-defense and anti-ship capabilities around Hormuz. The stated goal is safer tanker traffic. The market risk is an open-ended cycle in which Iran rebuilds, the United States strikes, and protected shipping remains dependent on continuing military action. President Trump said the United States would respond to Sunday’s Iranian attacks and “hit them hard.”
No Monday labor, consumer or DOGE release changed the domestic picture. Russia’s fifth straight day of drone pressure around Kyiv and the China-Russia-India summit add geopolitical weight, but neither displaced Hormuz, oil and rates as the deployment drivers.
The pulse remains RED. Keep exposure reduced or hedged. A mild index decline and volatility still below 15 argue against CRITICAL. A $90 oil close, a 4.75% long yield, two-thirds odds of a September hike and the prospect of repeated U.S. strikes argue against YELLOW.
Tuesday’s JOLTS report is the next test. A clean de-escalation, sustained protected traffic, Brent below $85 and falling hike odds would move me toward YELLOW. Approval of recurring strikes, another Iranian response, Brent above $95 or a broad volatility and credit break would move the pulse to CRITICAL.
