Chip Prices Jumped 27% While US Wholesale Inflation Cooled

US wholesale inflation slowed more sharply than forecasters expected in July, with the producer price index up 4.7% over the year against 5.5% in June. Month on month, prices didn't move at all — economists had pencilled in a 0.2% rise. The Bureau of Labor Statistics released the figures on Thursday 13 August, a day after a consumer price report that also came in soft.

Strip out food and energy and the picture holds. Core producer prices rose 4.2% on the year, the slowest in four months and down from 4.7%. Wholesale energy costs fell 3.1%. Food prices dropped for a second month running. Much of this is the oil spike from the Iran conflict washing out of the data — producer inflation hit a four-year high of 5.9% in May.

None of this is purely an American story. The Bank of England held Bank Rate at 3.75% for a fifth meeting running on 30 July, three of its nine rate-setters voted to push it to 4%, and UK fixed mortgage pricing follows swap markets that twitch whenever American inflation data lands. A cooler United States buys the Monetary Policy Committee breathing room. A hotter one takes it away.

What the US wholesale inflation figures showed

The producer price index tracks what businesses charge each other, before anything reaches a shop shelf. It's noisier than consumer prices but it arrives earlier in the chain, which is why economists treat it as a rough preview of what's coming. On that reading, July's US wholesale inflation numbers say pipeline pressure is genuinely easing.

It isn't uniformly clean, though. A narrower core gauge that also strips out trade services rose 0.4% on the month, above the 0.3% consensus, and was still running at 4.7% annually. So the headline softened while one closely watched underlying measure firmed — the sort of split that lets hawks and doves both claim the day.

The one number that went the other way

Buried in the detail sits a figure with nothing to do with oil. Prices for semiconductor and electronic component manufacturing were up 27.1% over the year, according to CNN's reading of the release. That is not a rounding quirk or a seasonal wobble. It is the artificial intelligence data-centre build-out showing up as measured inflation.

It matters more than the usual component noise because chips feed into almost everything: cars, washing machines, medical equipment, industrial controls, and the servers behind every cloud bill your employer pays. If energy is the input currently falling and silicon is the input climbing 27% a year, the composition of inflation is shifting even where the headline looks calm.

Why this lands differently in Britain

Britain's inflation problem in 2026 is not America's. But the two are being fought with near-identical interest rates, and the US wholesale inflation data feeds a global rates market that prices British mortgages without much regard for borders.

Two central banks, both stuck at 3.75%

The Federal Reserve's target range tops out at 3.75%. Bank Rate is 3.75%. That's coincidence rather than coordination, but it means neither side of the Atlantic can look relaxed. US consumer inflation was 3.4% in July with core at 2.5%, the coolest since March 2021. UK CPI was 2.6% in June, and the Bank's own projection has it peaking near 3.2% in the final quarter of this year.

The three votes for a rise on 30 July

The MPC split 6-3. Huw Pill, Megan Greene and Catherine Mann wanted 4%, arguing that higher energy costs risk becoming embedded. The majority pointed to softening pay growth and weaker activity, saying the evidence of spillover wasn't there yet. All nine agreed that energy price risks point upwards — precisely the risk a falling American energy component quietly trims.

The date to put in your diary

The next Bank Rate decision is expected on 17 September. Before then the Bank gets another UK inflation print and a fresh labour market release; the Fed gets an August jobs report and August CPI ahead of its own meeting. Two soft American reports in two days won't settle anything in Threadneedle Street, but they do remove one argument from the hawks.

Why traders are betting on a hike, not a cut

Here's the part that catches people out. For most of the past two years the question was when rates would come down. Right now futures markets are handicapping whether the Fed goes up. After the July consumer price report, CME Group's FedWatch tool put the odds of a September hold at 64%, up from 52% the previous day. The alternative being priced is a rise.

Energy is the reason, and energy is unfinished business. Ben Ayers, senior economist at the American insurer Nationwide — no relation to the British building society — summed up the caveat in remarks reported by CNN.

Fuel prices remain a wild card because of the ongoing Iran conflict.

What to do if you're remortgaging this autumn

The practical read: if your fix expires within six months, July's American data weakened the case for UK rates going up rather than strengthening the case for them coming down. Swap rates price expectations, and expectations just shifted from "possible hike" towards "probably nothing". That argues against waiting for a dramatic fall in fixed-rate offers.

Most lenders let you reserve a rate up to six months ahead and re-book if pricing improves, which costs a form and nothing else. Savers should read it in reverse: with Bank Rate likely parked, the best easy-access and one-year fixed deals are unlikely to improve much, and the top of the best-buy tables turns over quickly.

Watch two things over the next month — the UK July inflation figure due later in August, and the MPC on 17 September. If the Bank's forecast 3.2% peak arrives on schedule this autumn, this week's good news from Washington won't count for a great deal by Christmas.
