BOJ needs to persistently continue easing - BOJ's Iwata

Comments from Bank of Japan's (BOJ) Deputy Governor Iwata are crossing the wires-

• BOJ must continue with powerful monetary easing. 
• Yield curve control is the most appropriate policy with the biggest effect, minimal costs. 
• BOJ should maintain current policy as long as it is not sure of the effects of other possible options.
• Still some distance from 2 percent inflation target. 
• Trying to restore fiscal health could slow growth, make achieving 2 percent inflation target difficult.
