Bank of Japan policymakers last month debated the need to examine the side-effects of prolonged monetary easing and the impact of a future exit from ultralow interest rates, a summary of opinions showed on Tuesday.

The summary suggests some policymakers are slowly becoming more open to the possibility of an eventual withdrawal of the radical monetary stimulus deployed by Gov. Haruhiko Kuroda nearly a decade ago.

Many in the nine-member board stressed the importance of sustaining ultraloose policy for now to ensure wages rise enough to compensate households for the rising cost of living, according to the summary of the October policy meeting.
