BOJ's Ueda vows to maintain easy policy given economic uncertainty

Bank of Japan Governor Kazuo Ueda said on Friday the central bank will patiently maintain its ultra-loose monetary policy given "very high" uncertainty over the economic outlook.

"The cost of prematurely shifting policy, and nipping the bud towards achieving 2% inflation, is extremely large," Ueda said in a speech at a seminar. "It's appropriate to take time judging (when to) tweak ultra-easy policy toward a future exit."
