A Surprising Rise in US Treasury Yields

Rate volatility is likely to persist as Fed pursues 2% inflation target

Key Insights

  • A sharp rise in US Treasury yields—pressured by a resilient US economy and supply and demand imbalances—has caught many investors by surprise.
  • We believe that rate volatility is likely to persist as the US Federal Reserve pursues a 2% inflation target and restricts monetary policy for longer than expected.

Despite evidence of easing inflation and peaking policy rates in the US, 10-year US Treasury yields surged in July and early August to levels not seen since late 2007, catching many defensively positioned investors by surprise. Several factors have pushed yields higher, including the strong US economy and supply and demand imbalances in the US Treasury market.

US economic data have continued to surprise on the upside, led by labour market strength, solid consumer spending, and above-trend growth. This has pushed out expectations of a sharp slowdown in growth or a recession. Meanwhile, the economic impacts of the Fed’s aggressive rate hikes have been delayed, and inflation has proven stickier than expected, especially in labour and housing markets. As a result, investors now expect rates to remain higher for longer, a shift reflected in the federal funds futures market (Figure 1).

Supply and demand dynamics in the US Treasury market have also pressured yields higher. On the supply side, the US Treasury surprised markets at the end of July when it announced the need to issue more debt in order to fund the government’s growing budget deficit. This additional supply comes at a time when demand has been falling (Figure 2). The largest Treasury owners—the Federal Reserve and investors outside US—are buying less US debt amid quantitative tightening and more attractive yields on global bonds relative to Treasuries.

Rate volatility is likely to persist, in our view. As the Fed pursues a 2% inflation target, US monetary policy also may remain restrictive for longer than many previously expected. While it is hard to predict if we have seen the top in rates, we believe a much higher neutral rate1 is likely given the resilient US economy.

With this backdrop, our Asset Allocation Committee has remained balanced across fixed income sectors, maintaining an overweight to cash and cash equivalents while opportunistically adding to longer-term Treasuries amid the recent move up in rates.
