In This Part of the U.S. Bond Market, 0% Is High and Alarming

The U.S. bond market is hurtling toward the clearest sign yet that the Federal Reserve’s shift into a hawkish gear is making a difference -- a real 10-year interest rate higher than 0%.

While all Treasury yields have climbed this year as the Fed began what’s expected to be an aggressive series of rate increases aimed throttling high inflation, in the past two weeks the baton has been passed to inflation-protected notes and bonds. Their yields are termed “real” because they represent the rates investors will accept as long as they are paired with extra payments to offset inflation.

For borrowers, whose revenues may rise with inflation, real interest rates represent a sort of true cost of money. For 10-year loans, it’s been negative since early 2019, except for briefly during the market mayhem of March 2020. Ten-year real yields on inflation-protected Treasuries surged to -0.15% from -0.49% in the past week. The trough was -1.26% in November.

“The Fed going to tighter policy should fundamentally argue for higher real yields,” said Michael Cloherty, head of U.S. rates strategy at the securities arm of UBS AG.

The era of negative real yields supported demand for riskier assets -- loosening financial conditions. To get inflation back under control, the Fed needs to tighten them via higher real yields. The pace may be faster this time. In late 2018, the 10-year real yield rose above 1% after exiting negative territory in 2016, as the Fed slowly tightened policy.
