Market veteran predicts bearish outlook for US Treasury yields

Steven Barrow, G10 strategist at Standard Bank, just raised his year-end forecast for the 10-year US Treasury yield to 5.2%. That’s up from an already aggressive 5% call he made earlier in the year, and he’s not stopping there: Barrow expects yields to push to 5.3% in the first quarter of 2027.

On September 14, the 10-year yield hit an intraday high of 5.01%, punching through the round-number barrier that markets have been nervously watching for months. The last time this yield closed above 5% was back in 2007, with only a brief spike in October 2023 offering a taste of what was to come.

Why yields are climbing

Brent crude prices have been hovering between $108 and $111 per barrel, fueled by supply concerns related to tensions with Iran. August’s Consumer Price Index came in at 3.4% annualized. Add in robust economic growth, increased Treasury supply hitting the market, and persistent fiscal deficits, and you get the ingredients for a yield environment that makes 5% look less like a ceiling and more like a floor.

Barrow isn’t the only strategist seeing higher yields ahead. Tracy Chen and Ian Lyngen have both signaled that yields could exceed 5% in the medium term, citing continued supply-side inflation and prolonged policy lags.

The 5% threshold matters more than you think

Mortgage rates key off this benchmark. So does corporate borrowing. When the risk-free rate sits above 5%, every other form of debt has to offer even more to attract capital. That means higher monthly payments for homebuyers, more expensive debt for companies looking to expand, and larger interest bills for a US government already running substantial deficits.

What Barrow’s call means for portfolios

Barrow’s forecast stands out because it’s notably more bearish than many of his peers. While several Wall Street strategists have issued lower year-end targets for yields, Barrow’s view reflects a conviction that the inflationary forces driving the bond selloff aren’t going away anytime soon.

For fixed-income investors, the rising yield environment creates an interesting paradox. Existing bondholders are watching the market value of their holdings decline, since bond prices move inversely to yields. But new buyers can lock in rates that haven’t been available in nearly two decades.

The housing market, already grappling with affordability issues, stands to feel the pinch most directly. Mortgage rates track the 10-year yield closely, and a sustained move above 5% on the benchmark would push 30-year mortgage rates even further from the levels that fueled the pandemic-era housing boom.

The divergence between Barrow and more dovish forecasters essentially boils down to a question about inflation’s staying power. If price pressures moderate and the Fed can begin easing, yields could retreat from current levels. If Barrow is right and inflation proves stickier than consensus expects, the bond market’s rough stretch is far from over, and 5.2% might end up being the conservative call.
