FX.co ★ US 5-Year Note Auction Yield Climbs to 3.98%, Marking Notable Rise from Prior Sale

The yield on the latest U.S. 5-year Treasury note auction rose to 3.980%, up from 3.615% at the previous auction, according to data updated on 25 March 2026. The move reflects a noticeable increase in borrowing costs for the U.S. government over the medium term.

The 36.5 basis point jump in the auction result points to changing conditions in the Treasury market compared with the prior sale, with investors now demanding higher compensation to hold 5-year U.S. debt. While the data alone do not explain the drivers, the higher stop-out yield suggests a shift in market pricing for interest rates and inflation expectations since the previous auction.
