The central bank wants to cut rates. The oil price won't let it. That's the trap.
The Setup
Eighteen months ago, markets were pricing five or six Fed cuts for 2026. Today, Polymarket puts the probability of zero cuts at 68%. Not because the economy is booming — because the US-Iran war has put a floor under oil at $90, keeping inflation sticky in exactly the places central banks can't ignore.
Core PCE: 3.3% (US) — above the 2% target with no clear path down
UK services inflation: 5.4% — the number Huw Pill can't look past
Fed real 10-year yield: 2.07% — the highest sustained level in over a decade
Not signs of an economy running hot. Signs of one being squeezed from the outside by a shock that monetary policy wasn't designed to fix.
The UK Version
Britain has been here before. In 2022, the Ofgem cap hit £3,549 a year. The government spent £37 billion blunting the impact. Mortgage rates doubled in months.
The echoes are uncomfortable. The Q2 2026 cap is £1,849 — still £400 above pre-crisis norms, with another revision expected in July. UK mortgage arrears are up 22% year-on-year. The BOE cut in May, then stopped. June's vote was 5–4 to hold. Chief Economist Huw Pill: "Services inflation is not falling fast enough. We cannot declare victory."
Liz Truss had a mandate, a majority, and a political programme. The gilt market was unimpressed. It didn't vote.
The Asymmetry
Demand-driven inflation has a clean tool: raise rates, cool spending. Supply-shock inflation doesn't. You can't drill your way out of a war. Raising rates can't produce more oil — it can only slow the economy on top of a shock that's already slowing it.
US households are paying $450 more a year on energy than in 2023.
UK borrowers are paying ~£300 more a month on their mortgages than in 2021.
Consumer confidence on both sides of the Atlantic is near multi-year lows.
People can feel it, even when the models move slowly.
The Exit
There is one. A ceasefire takes $5–8 off oil almost immediately. Inflation expectations compress. The case for cuts rebuilds quickly. Markets reprice fast.
But that exit isn't in the gift of any central banker. It's in the hands of diplomats and military commanders.
The trap isn't that central banks made the wrong call. It's that the most important variable affecting their decision isn't on any economic model. It's on a map.
