What’s Driving Treasury Yields Higher?

Key Takeaways

There’s been no summer vacation for the bond market this year. It seems there’s a new headline every day that needs to be processed and responded to. In terms of Treasuries (UST), yields at the back-end of the curve have risen in notable fashion and have resulted in rates being at levels not seen in almost twenty years in some cases. Against this backdrop, we thought it would be useful to help explain what is driving longer-dated Treasury yields higher, and perhaps more importantly, how can fixed income investors position their portfolios.

The ‘Warsh’ Effect

We have been consistently blogging and podcasting about the impact new Fed Chairman Kevin Warsh has had, and will likely continue to have on UST valuations. The complete lack of forward guidance from Warsh has created an elevated uncertainty quotient for the bond market, resulting in elevated volatility and interest rate (duration) risks. Oftentimes, the yield on maturities such as the ten-year note, carry a term premium, or the extra yield needed to compensate for such uncertainties. Throw this on top of inflation concerns and you get a recipe for higher long-term rates.

The ‘Crowding’ Out Effect

Another potential key factor that has flown under the radar but is gaining an increasing amount of attention is the huge rise in debt issuance tied to the massive AI-related buildout. This floodtide of new supply has impacted quite a few fixed income asset classes as investors have witnessed heavy borrowing from hyperscalers and technology companies in the U.S. investment grade and high yield sectors, as well as in the asset-backed securities space. It has been reported that thus far in 2026 AI-related debt issuance alone has been almost $500 billion. Remember, this comes in the wake of elevated Treasury supply in order to fund the nearly $2.0 trillion U.S. budget deficit.
