Yields rose at the Treasury's weekly sale of short-term bills yesterday.
The auction was held early because Monday is a federal holiday.
The average return on 13-week bills rose to 15.464 percent from 14.430 percent last Monday and was the highest since 15.423 percent on Dec. 15.
For the 13-week bills, the Treasury received $8.76 billion in tenders and accepted $4.3 billion at returns ranging from 15.401 percent to 15.488 percent, including $705 million of noncompetitive tenders at the average return. The coupon equivalent rate was 16.17 percent.
The Treasury also announced it plans to sell $4 billion in cash management bills next Wednesday and 4.5 billion of 52-week bills next Thursday.
Tenders for the 114-day cash management bills, in minimum amounts of $1 million, must be received by 1:30 p.m. on Wednesday at Federal Reserve banks or branches. The department said only competitive tenders will be accepted.
Tenders for the 52-week bills, to redeem $4.02 billion of maturing securities and to raise $500 million in fresh cash, must be received by 1:30 p.m. Thursday at the Treasury or at Federal Reserve banks or branches. They will be sold in minimum denominations of $10,000.
