DUBAI, Nov 2 (Reuters) - Qatar's central bank sold all 1.45 billion riyals ($398 million) of Treasury bills on offer at a monthly auction this week, with yields rising from the last sale, data released by the central bank showed on Wednesday.

It sold 650 million riyals of three-month bills at 1.51 percent, 500 million riyals of six-month bills at 1.73 percent, and 300 million riyals of nine-month bills at 2.00 percent.

In early October, the central bank had sold 550 million riyals of three-month bills at 1.44 percent, 300 million riyals of six-month bills at 1.63 percent, and 150 million riyals of nine-month bills at 1.99 percent.

In the data for the latest auction, the central bank did not reveal the size of bids for the various maturities, as it had done for previous auctions. It did not give a reason for the change.
