The yield on US Treasury bills maturing in six months has risen to 2.4%, marking the highest level for the instrument since January 2025.
The move underscores continued upward pressure on short-term rates as markets adjust to the prevailing monetary environment.
This repricing in the short end of the curve comes as broader US government borrowing costs also face headwinds.
The benchmark 10-year Treasury note yield has recently climbed above 4.35%, adding more than 2 basis points in recent trading sessions.
The simultaneous rise in both short and intermediate-term yields suggests a broadening of selling pressure across the government bond market.
The shift in short-term rates coincides with adjustments in other Treasury instruments.
