NEW YORK — The 10-year Treasury yield is sliding as markets pare back aggressive expectations for AI-driven productivity gains and inflation, reversing the higher-for-longer positioning that dominated earlier this year.

The shift reflects a crucial repricing: bond investors are scrubbing growth forecasts and extending duration exposure. When yields fall, longer-dated instruments see capital appreciation—a tailwind for duration positioning that had been bruised by rate hikes.

But term premium remains the critical constraint. The compensation investors demand for holding 10-year paper versus rolling shorter-dated bills—pricing in future rate uncertainty and inflation risk—has not collapsed. A sticky term premium puts a floor under how far yields can fall even as growth expectations dim.

The market is now testing whether AI re-evaluation locks in sustainably lower inflation, or whether fiscal pressures and structural dollar demand will re-elevate term premium and cap the rally in long-end duration.
