TOKYO, July 29 (Reuters) - The Bank of Japan expanded monetary stimulus on Friday through a modest increase in purchases of exchange-rated funds, yielding to pressure from the government and financial markets for bolder action to spur growth and accelerate inflation towards its 2 percent target.
But the central bank maintained its base money target at 80 trillion yen ($775 billion) as well as the pace of purchases for other assets including Japanese government bonds.
It also left unchanged the 0.1 percent interest it charges to a portion of excess reserves financial institutions park with the central bank. BOJ Governor Haruhiko Kuroda will hold a news conference at 3:30 p.m. (0630 GMT).
