New federal data released Wednesday confirmed what many Americans already felt: inflation is accelerating again. The Labor Department reported consumer prices rose 4.2% in May from a year earlier, the highest in three years, marking the third consecutive monthly increase.

Inflation now sits well above the Federal Reserve's 2% target, a level it has exceeded for over five years. New Fed chair Kevin Warsh will preside over his first policy meeting next week. The central bank is expected to hold interest rates steady but may drop language suggesting a future rate cut. Markets now anticipate a possible rate hike by year-end.
