SHANGHAI — China's central bank has hundreds of billions of yuan worth of bonds at its disposal to borrow, and will sell them depending on market conditions, the bank told Reuters on Friday, part of a plan markets see as an effort to cool a powerful bond rally.

The People's Bank of China (PBOC) will borrow the medium- and long-term bonds on an open-ended unsecured basis and sell them depending on market conditions, as it has signed agreements with several major financial institutions regarding bond borrowing, according to the bank.
