Persistently higher yields at U.S. Treasury auctions are increasing the cost of refinancing debt and funding future deficits, as investors demand greater compensation to absorb Washington's borrowing needs, raising questions about their appetite to continue buying U.S. debt.
Investors are concerned about the sheer volume of borrowing that must be financed in the years ahead, analysts said. U.S. national debt is approaching a record $40 trillion, according to the Treasury Department, while the fiscal deficit remains large.
"The overall market environment is definitely requiring Treasury to pay more to borrow," said Zachary Griffiths, head of macro and investment-grade strategy at CreditSights in Charlotte, North Carolina.
"It is more of a problem longer run if we're going to run budget deficits of 5% to 6% of GDP. Part of that is a fiscal and inflation risk premium, among other things."
Two Treasury auctions in the past week drew attention for their yields — the sale of 10-year notes cleared at a high yield of 4.683%, the highest in 19 years, while the 30-year bond auction stopped at 5.216%, a 25-year peak.
Still, Treasury demand has held up even as yields have risen to multi-year highs. The same forces driving yields higher — namely inflation concerns, widening fiscal deficits and rising debt supply — are also boosting the compensation investors receive for holding U.S. government debt.
