Japan's key money supply gauge rose 3.6 percent in April from a year earlier while the balance of quasimoney -- most of it time deposits -- saw a record drop in the wake of the April 1 abolition of the government's full-refund guarantee, the Bank of Japan said Friday.

The average daily balance of M2 -- cash in circulation, demand deposits and quasimoney -- plus certificates of deposit came to 671.2 trillion yen, compared with a revised 663.1 trillion yen in March, the central bank said.

The pace of growth in the key money supply gauge for March was revised to 3.7 percent from the originally reported 3.8 percent.
