US inflation slowed much more than expected in June, offering the first meaningful challenge to the recent surge in Federal Reserve tightening expectations. Headline CPI fell -0.4% mom, slowing from 0.5% mom in May, while the annual rate eased from 4.2% yoy to 3.5% yoy. Core CPI was unchanged on the month, bringing the annual core rate down from 2.9% yoy to 2.6% yoy. Both headline and core inflation undershot market expectations, suggesting the recent inflation spike may have been more concentrated in energy than previously feared.
The sharp improvement was driven overwhelmingly by energy prices. The energy index fell -5.7% mom after posting consecutive monthly increases of 10.9%, 3.8% and 3.9% over the previous three months, marking the largest monthly decline since April 2020. That more than offset continued increases in shelter and food prices.
Shelter inflation slowed further, rising just 0.1% mom, the smallest monthly increase since January 2021, while food prices increased a modest 0.2% mom. Together, the data suggest underlying inflation pressures continued to moderate once the temporary energy shock began to unwind, despite energy prices still standing 15.7% above their level a year earlier.
Attention now shifts to Fed Chair Kevin Warsh’s congressional testimony, where investors will look for clues on whether policymakers view the softer inflation report as sufficient to temper recent rate-hike expectations or continue emphasizing the inflation risks posed by the renewed surge in oil prices.
