(Bloomberg) -- China’s central bank added 250 billion yuan ($35 billion) into the banking system, the largest amount in a daily open market operation since May.

The People’s Bank of China net injected the cash via seven-day reverse repurchase agreements, according to two traders at primary dealers. There were no facilities coming due Tuesday.

The move comes before a deadline for corporates to pay tax, which typically increases the demand for cash and tightens liquidity. China’s 10-year bond yield was little changed at 3.22%.
