Inflation: The Heat Is On?

Nearly two months ago, we penned a report discussing the possibility of (our term) "complation," or too much complacency regarding inflation. At the time with May inflation data in hand, there wasn't much of a discernible impact from tariffs; the same cannot necessarily be said now. The Consumer Price Index (CPI) has seen its year-over-year (y/y) rate move higher, as has the core CPI, which excludes food and energy. As shown in the chart below, y/y growth rates have started to creep back up—to 2.7% and 3.1%, respectively.

Some of the summer heat in CPI can be seen when looking at the month-over-month (m/m) changes, which also helps eliminate any of the base effects associated with y/y changes. As you can see in the chart below, the gains in June and July were hotter for both headline and core CPI. In fact, the latter's increase of 0.3% in July was the second largest increase this year.

In terms of what's helping keep CPI's y/y change elevated, it's a mix across the energy, goods, and services spectrum. At the top is natural gas (up nearly 14% y/y), followed by motor vehicle maintenance, tobacco, and hospital services. On the opposite end, it's clear that energy has been helping put downward pressure on headline CPI, given gasoline and fuel oil are both down notably (which helps explain why core CPI y/y is currently outpacing headline CPI y/y).
