The State Bank of Pakistan also kept the cut-off yield on the three-month paper unchanged at 8.1000 percent, while that on the 12-month T-bills fell marginally to 8.7784 percent from 8.7907 percent. The weighted average annual yield on the three-month and 12-month papers came at 8.1000 percent and 8.7674 percent, respectively, compared with 8.0954 percent and 8.7687 percent at the previous auction.
The Bank said it sold Rs 144.15 million ($2.41 million) of six-month bills, Rs 346.15 million ($5.79 million) of three-month bills, and Rs 6.574 billion ($110.06 million) of the 12-month paper.
It received total bids worth Rs 20.953 billion, against a combined pre-auction target of Rs 5.0 billion.
Settlement of the auction will take place on Thursday.
Immediately after the auction, the central bank injected Rs 11.48 billion into the market through a four-day reverse repo, but it failed to pull down short-term money rates.
Overnight rates remained pegged at 8.9 percent, just below the discount rate of 9.0 percent.
"Rates will remain high the whole week, as no major cash inflow is due," said a dealer at a local bank.
"There was probably a major payment today due to which a couple of foreign banks bought dollars," said a dealer at a local bank.
However, he said, overall dollar supplies were healthy enough to keep the rupee steady in the coming days.
