The Bank of Japan said the outstanding balance of current account deposits held by private financial institutions at the central bank stood at 30.32 trillion yen Wednesday, staying at the bottom of its target range of 30 trillion yen to 35 trillion yen.
Financial market watchers as well as some BOJ officials had earlier speculated that the balance would fall below the target range for the day due to weak fund demand from private financial institutions.
Brokerages and other buyers of government bonds also withdrew funds from their central bank accounts to make payments to the government.
Market watchers said there is still a possibility the balance will slip below the target range for a couple of weeks from late July.
A fall below the target range may increase speculation that the BOJ would have to lower the range, which could be interpreted as credit tightening.
