By Reuters Staff 1 Min Read May 5 (Reuters) - The U.S. Treasury Department said on Wednesday it will keep its coupon issuance steady over the coming quarter, and that declines in outstanding Treasury bills should slow. The Treasury said it will sell $58 billion in three-year notes next week as well as $41 billion in 10-year notes and $27 billion in 30-year bonds, unchanged from last quarter. Any shifts in borrowing needs will be met with changes in its issuance of Treasury bills and cash management bills, it added. The Treasury also said it expects Congress to raise or suspend the U.S. debt limit in a timely manner, and that it may take certain extraordinary measures if Congress does not.
