Recent strength in the 30-year Treasury yield, recently near 5.66%, stems primarily from the Federal Reserve’s hawkish September 2026 policy shift, with the target range lifted to 3.75-4.00% and median projections now pointing to 4.1% by year-end and sustained into 2027 amid upgraded core PCE forecasts. Elevated term premiums reflect heavy Treasury supply against a federal debt stock above $40 trillion, combined with robust corporate issuance for AI infrastructure that competes for long-duration capital. Stronger growth expectations and policy uncertainty have lifted real-rate components, while anchored long-term inflation expectations limit pure inflation-driven moves. Key near-term catalysts include the October and December FOMC meetings plus incoming labor and inflation data that could alter the implied path for the federal funds rate.
