Barring something extraordinary, the Fed will raise interest rates on Wednesday for the first time since 2023. August CPI came in at 3.4 percent with prices up 0.4 percent on the month, and core inflation accelerated to 0.3 percent from 0.2 percent, hotter than forecast. Markets moved from about 70 percent odds of a hike to roughly 90 percent within minutes. A third of the monthly increase came from gasoline, now 27 percent more expensive than a year ago. Yet the more interesting question is not whether the Fed hikes. It is why a central bank would tighten into a consumer this fragile, with sentiment at 47.8 and oil trading near $100. The answer sits in one number most people skipped.

That number is 4.6 percent, the University of Michigan's reading of what consumers expect inflation to be a year from now, and it came in above forecast. Set it beside a sentiment index at 47.8 and you have the tension defining this moment: people feel poorly about the economy and simultaneously expect prices to keep climbing. Central banks treat rising inflation expectations as more dangerous than a slowdown, because expectations become self-fulfilling. If households and businesses believe prices will rise, they ask for higher wages and set higher prices, and the belief produces the outcome. This is what Warsh meant at Jackson Hole when he said price stability is not self-executing. A hike on Wednesday would be aimed as much at that 4.6 percent as at the 3.4 percent headline.
The second thing worth understanding is how an energy shock becomes a core inflation problem. Core CPI excludes energy, so in theory an oil spike should not touch it. In practice, diesel crossed $6 a gallon this week, and diesel moves the trucks and trains that carry nearly everything. Freight costs sit quietly inside the price of goods that have nothing to do with fuel. Core accelerating from 0.2 to 0.3 percent is that transmission beginning to show, which is exactly why the Fed reads a broadening as more serious than a headline spike. Meanwhile Saudi Arabia shut its East to West crude pipeline after attacks, the IEA cut its global supply outlook sharply, and the ECB raised rates on Thursday. This is no longer a US-only story.

US30 (Dow Jones) |
52,573 | -1.6% w/w |
The Dow closed at 52,573, down 1.6 percent on the week, with the S&P off 0.8 percent at 7,656.98 and the Nasdaq down 0.7 percent. Four consecutive losing sessions preceded a sharp Friday bounce of nearly 1 percent across the board. That rebound deserves explaining, because stocks rallied on data that all but confirmed a rate hike. The reason is that the CPI print removed uncertainty rather than creating it, and markets frequently prefer a known outcome to an unknown one. The VIX fell more than 11 percent to 15.84 on Friday alone. Worth noting the S&P spent Thursday near its 50-day average around 7,590, having traded above it since late July.
Price action suggests: A test of the 50-day average that held, with Friday's relief rally reflecting removed uncertainty rather than good news.

Gold (XAUUSD) |
Weekly close ~$4,390 | -2% w/w |
Gold closed near $4,390, down more than 2 percent on the week and its second consecutive weekly decline. This is the cleanest illustration we have had of a point this letter keeps returning to. Gold is widely described as an inflation hedge, and yet it fell in a week when inflation data came in hot. The reason is that gold responds to what inflation causes rather than to inflation itself. Hot data means higher rates, higher rates mean a greater cost of holding an asset that pays no income, and gold falls. It did firm on Friday as the dollar steadied, but the weekly direction was set by rate expectations, as it has been all year.
Price action suggests: A second weekly decline driven by rate expectations, with Friday's steadying showing buyers still present lower down.

WTI Crude Oil |
near $100 | Brent at 4-month high |
Crude traded around $100 after another sharp weekly advance, with Brent reaching a four-month high before slipping on Friday amid reports of possible talks over the Strait of Hormuz. The supply picture deteriorated materially: Saudi Arabia shut its East to West pipeline after multiple attacks, and the IEA now expects global supply in 2026 to fall by around 5.7 million barrels a day, roughly 6 percent, having previously estimated 4 percent. Refiners across the board hit 52-week highs. When a supply forecast is revised down by that much, price is responding to something structural rather than to a single headline, which makes it harder to unwind quickly.
Price action suggests: Acceptance near the $100 area on a genuine supply downgrade, with Friday's pullback looking like profit-taking.

EUR/USD |
ECB hiked | dollar little changed |
The ECB raised rates on Thursday as expected, and the euro finally had a domestic catalyst after weeks of trading purely on the dollar leg. The pair moved less than that might suggest, because the dollar finished the week little changed with a Fed hike now largely priced in. This is the clearest example yet of why an expected decision often moves a currency less than a surprise one. Both central banks are now tightening into an energy shock they cannot control, and when two sides move in the same direction the rate differential barely shifts. Watch instead for which bank sounds more committed to continuing.
Price action suggests: A muted reaction to an expected hike, with both sides tightening and the differential largely unchanged.

GBP/USD |
UK CPI due this week |
Sterling drifted in a quiet week for UK data, with the dollar finishing roughly flat. The energy point we raised last week now has real weight behind it: with crude near $100 and diesel above $6 a gallon, Britain's position as a large net energy importer is a genuine drag on the pound that builds slowly rather than showing up in any single session. UK CPI arrives this week and will tell us whether the same broadening we saw in US core inflation is appearing there too. That is the more useful thing to watch than the daily price action.
Price action suggests: Drift ahead of domestic inflation data, with the energy import burden a slow accumulating pressure.

USD/JPY |
BoJ decision this week |
Japanese equities fell almost 2 percent on Friday as investors positioned for a possible Bank of Japan rate hike this week, and that possibility matters more for this pair than anything that happened in the past five sessions. We have spent six weeks making the case that intervention cannot fix a rate gap and only a change in the underlying differential can. A BoJ hike alongside a Fed hike would leave the gap roughly intact. A BoJ hike without one, or with clear signals of more to come, would be the first genuine narrowing since this began. Both central banks meet within two days of each other.
Price action suggests: Positioning ahead of two central bank decisions, with the rate gap itself finally in play.

USD/CAD |
strong oil tailwind |
Crude near $100 gives the Canadian dollar its strongest tailwind of the year, and it comes at a useful moment given the tariff dispute that has weighed on the currency since late August. Canada also publishes its own CPI this week, which adds a domestic input to a pair that has been driven mostly by external forces. Of the seven markets we cover, Canada is the one clear beneficiary of an energy shock, since it exports what everyone else is paying more for. That structural advantage is easy to forget when the daily price action is choppy, but over a sustained oil move it tends to assert itself.
Price action suggests: The energy channel providing real support, with domestic inflation data the next input.

If the Fed hikes on Wednesday it will be the first increase since 2023, and the decision itself is already in the price. What is not priced is the guidance, and Warsh has made a point of not giving any. So the dot plot becomes the most informative thing in the room, and even that only shows a range of views rather than a plan. There is no advantage in positioning for a decision the whole market already expects. Read what follows it instead, and stay patient.
