Oil, the Iran war and your wallet

Oil sits behind most of this year's inflation story. The US war with Iran lifted crude prices, which flowed into gasoline and the consumer price index.

From crude to the pump

Gasoline prices follow crude with a lag, plus refining margins and taxes. In September gasoline was up 34.2% from a year earlier, and it accounted for more than half of the monthly rise in CPI.

Where prices are now

Brent fell nearly 9% on November 4 on hopes that political changes after the US elections could reduce escalation risk, and stayed below $100 a barrel. WTI closed near $90 on November 6.

Why oil matters for rates

Energy lifts headline inflation. If oil keeps falling, the Fed has less reason to hike. If it spikes again, the reverse holds.

Who is exposed

Households that drive long distances, airlines, shipping and chemical firms feel higher oil first. Energy producers benefit.

What you can control

Fuel efficiency, trip planning and fixed-price energy plans where offered. Beyond that, avoid building an investment plan on a prediction for oil, which has surprised forecasters repeatedly.
