Inflation Hit 3.7%. October Hike Odds Went From 21% to 47% Before Lunch. Gold Paid for It.

21% to 47%. That’s how far the odds of an October Fed rate hike moved in one morning, according to Adam Button of InvestingLive, as quoted by Kitco. The trigger was September CPI. After the release, Kitco had gold down more than 1% at $4,107.30.

A month ago I wrote about the exact opposite. In September, core inflation came in hot, and gold rose 1.38% anyway. Same kind of data, opposite result. The difference tells you what is actually moving your stack right now.

What Printed

Headline CPI rose to 3.7% year over year, up from 3.4% in August. Economists had expected 3.6%, per CBS News. The monthly gain of 0.6% was in line with forecasts, per Kitco.

Most of that is gasoline. The gas index rose 9.1% in September and accounted for more than half of the monthly increase. Year over year, gasoline is up 34.2%. AAA’s national average was $4.33 a gallon Wednesday, per CBS, against $2.98 before the war started. You didn’t need the Bureau of Labor Statistics to tell you that. You needed a gas station.

The number that mattered more was core, which strips out food and energy. It rose to 2.6% from 2.4%, against a 2.5% forecast. Jeffrey Roach, chief economist at LPL Financial, told Kitco that “inflation pressures are broadening beyond energy.” That is the sentence the Fed hates hearing most.

Why Gold Rose Last Month and Fell This Month

In September, a hike was already mostly priced in before CPI hit. A hot print didn’t change the rate math much, so the market treated it as an inflation story. Gold likes inflation stories.

This time the market had gotten comfortable. At the end of September, October hike odds fell from about 70% to the low 40s after a soft PCE report. By this morning they were down to 21%. Traders had talked themselves into a pause. CPI talked them back out of it.

After the report, futures priced 36 basis points of tightening for the rest of the year, up from 27, per Kitco. Dollar index futures climbed above 102.40, and the 10-year Treasury yield pushed toward 5.29%, per TradingView. Silver fell about 2% to below $58.

Gold pays you nothing. When a 10-year Treasury pays close to 5.3% and the Fed might hike again in two weeks, the cost of holding a yellow rock goes up. That’s the whole trade. It isn’t sophisticated, and it doesn’t need to be.

The Number That Should Humble Everyone

Fortune’s 9 a.m. tracker had spot at $4,095. A year ago, same tracker, it was $4,109.

Read that again. A war, 3.7% inflation, gas at $4.33 and a Fed that started hiking again in September, and gold is roughly where it was last October. With consumer prices up 3.7% over that stretch, an ounce bought a year ago has actually lost a little ground in real terms. That’s the uncomfortable truth about inflation hedges: the case for them is made over decades, not on any calendar you get to pick. I own gold for the 20-year version of this story, not the 12-month one.

The Bottom Line

The next real event is the Fed meeting on October 27–28. That’s the coin flip that matters, not today’s print. If the Fed hikes, expect more pressure on gold from yields and the dollar. If it holds, today’s selloff may look like an overreaction in hindsight.

Nobody knows which you’ll get, including the people pricing it. They moved their odds by 26 points in a morning. If you buy on a schedule, the schedule was built for exactly this kind of morning. Two inflation reports, one month apart, sent gold in opposite directions. Don’t try to call the third.
