The Fed's Problem Is a Barrel of Oil

Brent settled at a six-month high. The Fed meets Wednesday, and December's question is a hike.

The Close

The Dow lost 652.82 points, or 1.2%, to 52,215.16 — the worst of the four indexes. The S&P 500 slipped 0.5% to 7,623.68 and the Nasdaq Composite only 0.2% to 25,955.34. One sector went the other way: energy rose 2.5%, to a record high.

Brent crude settled at $116.72, up 3.1% on the day and 6% across the week, its highest close since April, after Houthi attacks across Saudi Arabia including on energy infrastructure. That is no longer just an oil story. The Federal Reserve announces its decision on Wednesday.

One Big Thing

Oil is unlike almost any other price because it is an input to nearly everything else. It moves the goods, heats the buildings, makes the plastic and the fertiliser, and gets the food to the shop. When crude rises, that cost does not take a year to reach the shelf. It shows up in the inflation figures within weeks, which is more than can be said for wages or rents.

Which is why Friday mattered beyond the energy sector. The Fed's target is 2%, and inflation has sat above it for five years running. The federal funds rate is 3.75% to 4% after an increase in September. Three policymakers dissented in July arguing rates should be higher still. The committee now arrives at Wednesday's decision with inflation already uncomfortable and crude 6% dearer than it was a week ago.

For most of this year investors have argued about artificial intelligence. This week they have to think about the price of a barrel of oil.

Futures markets put the odds of no change on Wednesday at roughly eight in ten, and firmly expect an increase at the December meeting. Note the direction of that sentence. The debate is not about when cuts arrive. It is about how much higher rates go.

That also explains why the Dow fell six times as hard as the Nasdaq. The Dow is stocked with industrial, consumer and financial companies — the businesses whose fuel bills rise immediately and whose customers notice. Friday was not a technology problem.

The Chart That Explains It

Friday in one picture. Crude settled at a six-month high after attacks in Saudi Arabia, the energy sector reached a record, and everything else gave ground. Note which index fell hardest. It was the Dow, not the Nasdaq, and the gap between them is the whole point.

The Deeper Read

There are two kinds of rising prices and they call for opposite responses. When prices rise because people are buying more than the economy can make, higher interest rates work: they cool the buying. When prices rise because a tanker did not sail, higher rates do nothing whatever to the supply. They simply slow an economy that is already being squeezed by the cost of fuel.

Central banks know this, which is why they have historically tried to look past supply shocks rather than chase them. The catch is that looking past one only works if everybody agrees it is temporary. Once households and businesses start assuming higher prices are permanent, they behave accordingly, and the shock stops being a shock and becomes the new normal. After five years above target, the Fed's appetite for calling anything temporary is probably thin.

The honest counterpoint: oil spikes caused by conflict very often unwind as fast as they arrive. Infrastructure gets repaired, shipping reroutes, and the fear premium drains away. Nobody reading Friday's tape knows whether this is a three-week event or a three-quarter one. The Fed does not know either, and it has to decide anyway.

What This Means For You

Start with something reassuring. If you hold a broad American index fund, you own the energy sector that hit a record high on Friday. You feel this oil price twice — once at the pump and once in your portfolio — and the second one quietly offsets part of the first. That is not a strategy anybody designed. It is just what owning the whole market does.

The part worth actually watching this week is not the oil price. It is Wednesday's statement, and specifically the language about December. Rates set the value of every bond you own and the discount applied to every future dollar of company profits. An oil spike is a headline; the policy rate is the plumbing.

And resist the urge to do anything about crude itself. Energy is the hardest sector in the market to time, because the thing that moves it is usually a piece of news nobody could have scheduled. By the time a spike is clearly a trend, the price has already been paid by somebody else.
