West Texas crude is above ninety dollars a barrel this week. Brent, the international benchmark, pushed back above one hundred. And the reason matters more than the number.

Houthi forces fired on Saudi tankers in the Red Sea last week, forcing them to turn back and effectively closing the Bab al-Mandab strait. That is the narrow passage at the southern tip of the Arabian Peninsula, the one roughly five million barrels of Saudi oil per day have to transit to reach Europe and Asia. It was already a tense region. Now it is closed. And this compounds the Straits of Hormuz situation that has been grinding through global energy markets since earlier this year.

So we have two of the world’s most critical oil chokepoints under pressure at the same time. Ukrainian attacks on Russian production added more disruption on top of that. Gasoline at the pump is running around four dollars and ten cents nationally. That is not a rounding error. That is a real cost landing on real households and real businesses right now, and it arrives at precisely the wrong moment in the inflation story.

The inflation numbers were already uncomfortable

Before any of this week’s energy news, the inflation picture was already worth a serious look. The personal consumption expenditures price index, which is the measure the Federal Reserve formally targets, was running at 4.07 percent above a year ago on the headline and 3.41 percent on the core (which strips out food and energy) as of the May reading. The Fed’s policy rate sits at 3.75 percent.

Pause on that for a second. The interest rate the Fed uses to fight inflation is below the rate of inflation itself. That means, in real terms, monetary policy is barely restrictive at all. The real policy rate, adjusting for core inflation, sits at just 0.22 percentage points above zero. That is about as close to neutral as you can get while still technically calling it a brake on the economy.

Now add a fresh crude oil shock. Gasoline prices feed directly into the headline inflation number, and they filter into services costs over time through transportation and logistics. The month-over-month annualized pace of headline consumer inflation was already running at a 5.53 percent annual rate in May. That was before the Red Sea closure and before crude punched back through ninety dollars.

The CPI components for June offer a slightly more nuanced picture. Goods inflation is contained, just under one percent year over year. Shelter is running at 3.48 percent. Services ex-shelter at 3.42 percent. The stickiest parts of the economy have not cooled much. Energy was the one category that looked like it might give the Fed some breathing room. That window may have just narrowed.
