BOSTON (Reuters) – The U.S. Treasury Department said on Wednesday it will sell $112 billion next week in notes and bonds and that it plans to continue to shift more of its funding to longer-dated debt in coming quarters, as it finances measures to offset the impact of the COVID-19 epidemic.

The Treasury said it expects its debt needs to moderate but remain elevated, after borrowing a staggering $2.753 trillion in the second quarter.

“Treasury continues to face unprecedented borrowing needs as a result of the federal response to COVID-19,” Brian Smith, Treasury’s deputy assistant secretary for federal finance, said on a conference call.

The Treasury will sell $48 billion in three-year notes, $38 billion in 10-year notes and $26 billion in 30-year bonds next week as part of its quarterly refunding.

It said on Monday that it plans to borrow $947 billion in the third quarter, about $270 billion more than it previously estimated for the July-September period.

The federal agency will use “long-term issuance as a prudent means of managing its maturity profile and limiting potential future issuance volatility,” Smith said in a release.

As Treasury increases auction sizes, it will have larger increases in 7-year, 10-year, 20-year and 30-year notes and bonds, he said.

Treasury has been raising extra money to fund trillions of dollars in coronavirus-related economic aid allocated by Washington. As of Tuesday, White House negotiators were trying to reach a deal with congressional Democrats to extend relief measures including unemployment benefits, liability protections for businesses and a moratorium on evictions.

Borrowing has spiked far above the quarterly record set during the 2008 financial crisis.

A declining economic outlook has driven down U.S Treasury yields across the curve to record or near-record lows, helping raise equity prices and lower borrowing costs.
