Core PCE Matched, but Headline Inflation Ran Hotter. Oil Tumbled on the Iran Pivot. Stocks Went Quiet Waiting on Nvidia and Warsh.

The market barely moved, and that was the story. July core PCE landed exactly in line at +0.2% MoM and +3.3% YoY — but headline PCE ran hotter than expected at +3.7% YoY versus 3.6% forecast, enough to lift Treasury yields and keep the Fed’s tightening risk alive. Stocks finished essentially flat: the S&P slipped 0.02% to 7,675.70, the Dow fell 113 points, the Nasdaq 0.08% — a session of almost total paralysis ahead of two events that land within 48 hours: Nvidia’s earnings after today’s close and Warsh’s first Jackson Hole keynote Friday.

Here’s what mattered:

📊 PCE — the split print

• Core PCE: +0.2% MoM, +3.3% YoY — matching expectations exactly.
• But headline came in at +3.7% YoY against 3.6% expected — a modest upside surprise that mattered more than its size suggested.
• Yields rose Wednesday, reversing Tuesday’s decline, as markets read the hotter headline as keeping the Fed’s tightening option open.
• The setup for Friday: core behaving, headline drifting, and no clean story either way — an awkward hand for Warsh at Jackson Hole.

🛢️ Oil tumbled Tuesday — the Iran pivot

• Brent fell 3.9% (-$3.59) to $88.58; WTI fell 3.1% (-$2.65) to $82.36 as the US shifted from military to economic pressure on Iran.
• The read: markets judged sanctions less threatening to physical supply than military escalation — the war premium draining out.
• The knock-on: that drove Tuesday’s yield relief (10-year down 7bp to ~4.625%), which supported equities before Wednesday’s inflation data reversed it.

📉 Tuesday’s rally, Wednesday’s stall

• Tuesday close: Dow +0.30% · S&P +0.32% · Nasdaq +0.66% · Russell 2000 +0.50% to 3,010.02.
• Wednesday close: Dow 53,463.88 (-113.52, -0.21%) · S&P 7,675.70 (-1.58, -0.02%) · Nasdaq 26,130.20 (-21.10, -0.08%) · Russell 3,005.90 (-0.14%).
• Dick’s Sporting Goods collapsed ~31% Tuesday — its worst day on record — after weak results and a cut to full-year adjusted EPS guidance.
• Nvidia rose 2.2% Tuesday, snapping a seven-session losing streak, and sits up roughly 13–14% in 2026.

🇨🇦 Canada retaliates

• C$27.6 billion (~US$20B) in retaliatory tariffs announced, covering 700+ products at 15%, 25% and 50%, effective Sept 8 — described as dollar-for-dollar matching of Trump’s duties.

📅 The next 48 hours

All times GMT, scheduled:

• TONIGHT: Nvidia earnings — the immediate test for the AI trade and risk appetite generally.
• THU (Aug 27): Marvell earnings (after close) · Jackson Hole begins.
• FRI (Aug 28) ⚡: Warsh’s keynote — his first as Chair.

🧠 Bottom line

A session this quiet isn’t indecision — it’s deferral. Core PCE behaved, headline didn’t quite, and the market decided neither was worth acting on with Nvidia hours away and Warsh two days out. The S&P moved two-hundredths of a percent. That’s a market holding its position, not forming a view.

The nuance worth carrying: yields rose on the hotter headline, undoing Tuesday’s oil-driven relief. So the inflation problem isn’t resolved — it’s just quieter than the war premium was. Nvidia is the one AI name that profits from the capex this earnings season has punished everyone else for spending; if it can’t clear the bar, the whole trade has a problem. Then Warsh steps up with core inflation cooperating, headline inflation drifting, a labor market that contracted in July, and a hawkish committee he can’t fully justify anymore.

Core PCE matched, headline ran hot, and the market did nothing at all. Nvidia and Warsh get the last word.
