The People's Bank of China (PBOC), the central bank, injected a total of 166 billion yuan (24.3 billion U.S. dollars) into the market this week through bill issues and repurchase agreements.

In its regular open market operations on Thursday, the central bank auctioned 10 billion yuan (1.46 billion U.S. dollars) worth of three-month bills with a yield of 1.5704 percent, up 4.04 basis points from June 3.

The central bank also raised 10 billion yuan through 91-day repurchase agreements on Thursday with a yield of 1.57 percent, up 16 basis points from previous repurchase agreement operations.

Thursday's operations brought the weekly total raised to 45 billion yuan (6.6 billion U.S. dollars), but a total of 211 billion yuan (30.9 billion U.S. dollars) matured this week, resulting in a net weekly injection of cash.

The PBOC has realized net injections of money into the market for three straight weeks in a row.
