Fuel costs push US inflation to 3.7% while wages grow 3%

The Bureau of Labor Statistics tied the monthly move to a single component. "The index for gasoline rose 9.1 percent in September, accounting for over half of the monthly all items increase," the bureau said ^[2]. The published coverage does not include a core reading, so how much of the 3.7% annual rate ^[3] comes from energy alone is not yet known.

The case for waiting is that one component accounted for over half of the monthly rise and oil could retreat. If it did, we would expect part of the 0.3-point acceleration from 3.4% ^[11] to reverse. The BBC reports that crude traded at just over $70 a barrel before the conflict and is now over $100 ^[14], so no retreat has started. Diesel, which powers businesses, farms and shipping, has also risen faster than regular gas since late February ^[5][6]. That is a cost operators buy directly.

Pay is the second line. NBC News reported that paychecks have not grown faster than inflation since March ^[15]. Set against 3.7%, wage growth of 3% leaves a gap of 0.7 points ^[16]. The Federal Reserve targets 2% ^[8], and the annual rate is 1.7 points above that ^[9]. In our view the gap is the larger exposure for employers who plan raises near the current pace, because it has persisted for months and is not a one-month effect.

The tariff channel is still open. In February the Supreme Court outlawed most of the remaining additional global levies, and the president immediately announced a new 10% global tariff to replace them ^[19]. New York Fed research found that every percentage point added to average tariffs led to nearly a 0.25% rise in consumer goods prices after one year ^[18]. Because that effect is measured over a year, we think it overlaps with the fuel effect in current prices.

The tradeoff is timing. A surcharge set this quarter against a 3.7% rate ^[3] will look high by next quarter if oil retreats. A wage budget held near 3% ^[13] will look low if oil does not retreat. Pay has trailed inflation since March either way ^[15].
