Treasury doubles long-dated buybacks to $4 billion, yields slide

US equity futures rose 0.6 percent after the Treasury at least doubled its long-dated bond buyback ceiling to $4 billion.

"The higher bond yields on long-dated securities, like the 30-year Treasury, clearly indicate discomfort over persistently high inflation in the future," Lawrence Yun, chief economist at the National Association of Realtors, said.

The 30-year yield fell as much as 9 basis points to 5.19 percent on the announcement. The dollar index dropped 0.6 percent, with every G10 currency advancing against the greenback and the yen up 0.9 percent to 158.17. Spot gold surged 2.5 percent to $4,440.25 an ounce, while silver climbed 2.4 percent to $64.83.

The move comes as long-term bonds have been heavily sold globally, with 30-year US yields touching 5.323 percent on Tuesday — the highest since 2007 — as July inflation ran at 3.4 percent, well above the Federal Reserve's 2 percent target. Traders are preparing for a $16 billion auction of new 20-year bonds.

The Treasury's decision to at least double buybacks in the long-dated sector points to stronger official demand for duration, which lowers yields and supports risk assets. Nasdaq 100, S&P 500 and Dow futures each rose 0.6 percent, while the dollar weakened against all major peers. The announcement follows a week in which 30-year yields surged to their highest since 2007, driven by persistent inflation and heavy selling in long-term bonds globally.

Borrowing Costs Stay Elevated

The elevated yield backdrop has already pushed consumer borrowing costs higher. The average 30-year fixed mortgage rate stood at 6.75 percent as of Tuesday, up from 6.69 percent last week, according to Mortgage News Daily. "The impact on mortgage rates is directly related to higher bond yields," Yun said. "Independent of the Federal Reserve policy, higher inflation and higher overall long-term borrowing costs will mean higher mortgage rates."

Rates on car loans, credit cards and student debt are also tied to bond yields. "Auto loan rates don't move in a vacuum, but sustained pressure on Treasury yields inevitably pushes up borrowing costs across the financing spectrum," said Jessica Caldwell, head of insights at Edmunds. With average new-vehicle APRs near 7 percent and used vehicles at 10.6 percent, "auto lenders will have little choice but to maintain or even bump up APRs," she said.

"Longer-term bond investors may need more evidence that the post-pandemic inflation cycle is truly behind us and that the economy is returning to a slower-growth, slower-inflation environment before 10- and 30-year Treasury yields move meaningfully lower," said Jeff DerGurahian, chief investment officer at LoanDepot.

The buyback expansion gives the Treasury more room to manage the long end of the curve as it funds a widening deficit. The $16 billion auction of new 20-year bonds will test demand at current yield levels, with the 30-year still near multi-decade highs even after Tuesday's pullback. For investors, the Treasury's willingness to step up purchases in the sector could cap further yield increases, though persistent inflation keeps the risk of renewed selling pressure.
