Yields rose on short-term T-bills in auctions that had been postponed from last week while Congress considered raising the national debt limit.

Another $6.42 billion was sold in new six-month bills at an average discount rate of 6.83%.The new discount rates understate the actual return to investors--6.81% for three-month bills with a $10,000 bill selling for $9,833.40 and 7.19% on six-month bills with a $10,000 bill selling for $9,654.70. The Treasury also rescheduled a series of other securities auctions. One-year bills will be auctioned Wednesday, three-month and six-month bills Thursday, four-year notes on Oct. 6 and seven-year notes on Oct. 7.
