RISK OPEN — Pre-Bell Briefing

Oil Eased Overnight. Diesel Didn't.

A hotter-than-expected August core inflation print landed the same morning Houthi forces seized a second Red Sea chokepoint and U.S. diesel crossed $6 a gallon for the first time ever — three signals that don't agree with each other, which is exactly why today matters.

Friday's August CPI report, released at 8:30 a.m. ET, showed headline inflation up 0.4% for the month and 3.4% year-over-year, matching consensus. Core inflation, which strips out food and energy, rose 0.3% — a tenth of a point hotter than the 0.2% economists expected. That single decimal point mattered: the 2-year Treasury yield posted its largest single-day move in more than a year, the 30-year yield touched 5.373%, its highest level since 2007, and prediction markets moved to roughly 70% odds of a Federal Reserve rate hike at next week's September 15–16 meeting. At the same time, oil pulled back sharply from Thursday's spike after the Financial Times reported that Middle Eastern foreign ministers are seeking a "temporary arrangement" with Iran to ease Strait of Hormuz shipping — even as Houthi forces captured Yemen's Red Sea port of Mocha on Thursday, opening a second potential chokepoint at Bab al-Mandeb, and the national average diesel price crossed $6 a gallon for the first time in history, with 28 states posting all-time highs.

Risk Signal 01 — A hot core CPI print has all but locked in a Fed decision

Transmission

Core CPI at 0.3% month-over-month, against a 0.2% forecast, is a small miss in absolute terms but a large one in context: it arrived during a week when oil-driven inflation risk was already the market's central worry. The confirmable fact is the reading itself and the yield-curve reaction that followed; what remains uncertain is whether next Wednesday's Fed decision will actually deliver the hike markets are now pricing, or whether policymakers judge a single hot core print insufficient justification on its own.

Risk Signal 02 — Oil fell on a diplomatic report, but the physical picture got worse

Pressure

Brent fell roughly $2 to around $103.70 and WTI to around $99 Friday morning after the Financial Times reported Gulf foreign ministers are pursuing a temporary shipping arrangement with Iran. But actual vessel transits through Hormuz fell to 7 on Thursday, down from 11 the day before and well below the 15-day average, according to shipping trackers — meaning the price relief is running ahead of any confirmed change in physical flows. Separately, and on the same day, Houthi forces seized the Yemeni port of Mocha near the mouth of Bab al-Mandeb, a development one regional analyst said could let the Houthis "control pretty much all of Yemen's coast on the Red Sea."

Risk Signal 03 — Diesel just crossed a line it has never crossed before

Escalation

The national average diesel price crossed $6 a gallon on September 10 for the first time in U.S. history, with 28 states — from California to Florida to North Dakota — posting all-time highs. This is not purely an Iran story: full detail on the four separate global disruptions converging on this one commodity is in today's Axis File.

Dominant Risk Classification

TRANSMISSION — the risk has now visibly reached real prices (diesel, mortgage-relevant long yields) and real policy decisions (the Fed), even as the headline oil price itself eases on unconfirmed diplomacy.

What Markets May Be Missing

Equity futures rose this morning despite a hotter-than-expected core inflation print — an unusual combination that suggests markets are more relieved by crude's pullback than concerned about the rate-hike odds it helped confirm. That relief may be premature: three of the four forces squeezing diesel supply (Russia's export ban, Ukrainian strikes on Russian refineries, and China's export quotas) have nothing to do with the Gulf and would not be resolved even if the reported Hormuz arrangement materializes.

Today's Confirmation Point

Watch whether Hormuz vessel transit counts recover toward their 15-day average in the coming days — that, not the FT report alone, would be the real signal that Friday's oil pullback reflects an actual easing rather than a hopeful headline.
