When a Bond Yield Rises, Ask Which Yield Is Rising

A ten-year Treasury yield is a single number doing two jobs, and Econbrowser's argument is that it matters which job is doing the work right now. Its read is that the recent rise in ten-year rates is mostly showing up in real rates, as proxied by TIPS, rather than in the nominal yield's inflation component. The chart tracks the change since late February 2026 in three things: the ten-year Treasury constant maturity yield, the on-the-run yield, and TIPS. TIPS are the inflation-protected side of the comparison — the place you look when you want the return after price growth is stripped out. If the move is concentrated there, the story is about the real cost of money, not about investors suddenly pricing in a nastier inflation path. Same headline number, two entirely different diagnoses, and different policy conclusions follow from each.
