Here’s an extremely brief effort to explain why bond yields going up is actually not bad news.

September 28, 2026
Rates. 10y yields briefly traded above 5.2% today, closing up 7 bps on the session. As shown below, they're the farthest from fair value that they've been in some time based on our qualitative model.

Our model assumes 2% inflation over the long term plus an inflation risk premium (35 bps, to use explicit TIPS pricing). With those values fixed, below we show the implicit growth (including risk premium around growth) forecast from the market given the consensus range of term premium (after backing out some amount off growth risk premium).
Current pricing assumes trend growth above 2% and rising.
