China’s central bank resumed injections into the money market on Thursday after a near three-week absence, in an apparent bid to ease fears of a cash crunch in the financial system following massive drains from maturing debt instruments.

The market has also been on edge after a flurry of moves by regulators to curb riskier lending activity, including a crackdown by the banking watchdog this week, on misdemeanours with a focus on shadow banking.
