Bond yields rise as market digests U.S. Treasury buyback intervention

Bond yields climbed Thursday, erasing most of the pullback they saw the previous day after the Treasury Department announced an intervention aimed at easing pressure on longer-dated government debt.

The yield on the 30-year U.S. Treasury bond — the primary focus of the accelerated buyback — was up more than 6 basis points at 5.256%.

Yields on 10-year U.S. Treasurys — the main benchmark for mortgages, auto loans and credit card debt — moved more than 5 basis points higher to 4.704%.

The 10- and 30-year yield levels were right around the level they held before the 8:30 a.m. announcement Wednesday that Treasury would be stepping up its bond buyback program.

The yield on the 2-year Treasury note, which more closely follows short-term Federal Reserve rate decisions, was last seen up less than 1 basis point at 4.187%.

One basis point equals 0.01%, or 1/100th of 1%, and yields and prices move inversely to one another.

The moves underscored the difficulty of market interventions, particularly at a time when U.S. debt faces a slew of factors that have been pressuring yields higher.

In a move announced Wednesday morning, the Treasury Department, led by Secretary Scott Bessent, said it would at least double the size of its government debt buybacks, starting Sept. 9 and running through Nov. 4.

Yields tumbled following the announcement, with the 30-year down about 10 basis points after previously hitting its highest in about 19 years, predating the global financial crisis in 2008.

However, the trade quickly unwound, with yields higher Thursday as the market digested the move as well as the longer-term structural problems facing the fixed income market.

Later that day, Bessent said that the buyback operation could end up being more than the $4 billion that was announced.

The interventions "belie the underlying structural challenges and do nothing to address them," Maia Crook, senior research analyst at JPMorgan Chase, said in a client note. "While [Wednesday's] action forced some decline in longer-dated yields, the more lasting impact is the potential for higher risk premia reflecting a Treasury Department that is intervening in the market and moving away from its 'regular and predictable' tenet."

The announcement came the same day that Treasury updated the national debt total, which pushed past the $40 trillion mark. At the same time, the market has faced stiff competition from record corporate debt issuance tied to the artificial intelligence build-out, all of which has contributed to rising term premiums, or the extra yield investors demand to hold U.S. government paper.

Traders were also digesting the latest Federal Open Market Committee minutes from July, released Wednesday. Officials at the meeting indicated that higher interest rates likely would be needed if there isn't more progress on inflation. Economic data released since the meeting has shown modest monthly price increases, though inflation remains above the Fed's 2% target.

On Thursday, the Philadelphia Fed's manufacturing index posted its highest reading since April 2021.
