Some members of the Bank of Japan's Policy Board expressed concern during the meeting Oct. 31 that resulted in the surprise expansion in monetary easing, citing negative "side effects" it may have on the economy, the minutes of their meeting show.
Those members said that in light of already historically low interest rate, any positive effect of looser monetary policy in reviving the country's struggling economy would be not so large, according to the minutes released Thursday.
BOJ Gov. Haruhiko Kuroda pushed past these dissenting opinions to expand the bank's stimulus program.
