Comments from Japan finance minister Aso: Up to BOJ to decide whether additional monetary easing is needed. What monetary policy can do to boost inflation is limited. BOJ monetary policy alone cannot achieve inflation target. BOJ's Kuroda must be counting on demand being boosted by companies spending cash piles on capex, wages. No need to change 2 pct inflation target at this stage. Don't think it's wrong to pursue 2 pct inflation with open-end policy.
