This morning's May CPI landed hot, and rates are repricing higher in real time. Headline inflation rose 0.5% on the month and 4.2% year over year, the fastest annual pace in three years and the highest since April 2023, topping expectations and confirming the acceleration that began in the spring. The 30-year fixed is moving up roughly 10 basis points to 6.51% as lenders reprice, while the 10-year Treasury holds near 4.55%, a sign the damage is concentrated in repriced policy expectations rather than a clean bond selloff.
Energy did most of the work, accounting for more than 60% of the monthly gain as the Iran conflict keeps disrupting Strait of Hormuz shipments and holds Brent crude near $93. Core CPI was calmer at 0.2% monthly and 2.9% annually, the one piece of good news, but the headline jump from 2.4% in January to 3.3% in March, 3.8% in April, and now 4.2% in May is a four-month trend the Fed cannot wave away a week before it meets. Futures now put the odds of a hold at 3.50% to 3.75% next week at roughly 96%.
For brokers, this is the print that ends the waiting game. Any borrower still floating in hope of a summer cut just watched that thesis take a serious hit, and the practical move is to lock rather than chase a rebound that the data does not support. Expect intraday reprices through the session as lenders digest the number, so files that can lock should lock early before pricing erodes further.
