The 5-year Treasury yield has risen sharply in September 2026, reaching 4.83% on September 21 after trading near 4.5% early in the month and touching 4.86% mid-month. The primary driver is the Federal Reserve’s unanimous 25 basis point rate hike on September 16, lifting the target range to 3.75%-4.00%, alongside resilient U.S. growth and sticky inflation that pushed the central bank’s 2026 PCE projection higher. Heavy Treasury supply, elevated term premium, and reduced demand from traditional buyers have added upward pressure across the curve. With September nearly complete, final economic releases and any late-month positioning could still influence the peak yield before resolution.
