Japan's monetary base expanded 1.4 percent in January from a year earlier for the 60th straight monthly rise, the Bank of Japan said Thursday.
The average daily balance of the monetary base -- cash in circulation plus current-account deposits held at the central bank by financial institutions and Japan Post -- rose to 114.132 trillion yen in January, the BOJ said.
The monetary base has continued to expand as the BOJ has maintained its quantitative monetary easing policy since March 2001 to pull the nation's economy out of deflation.
