BOJ's challenges include future exit from easy policy -nominee Amamiya

TOKYO, March 5 (Reuters) - The Bank of Japan faces various challenges ahead, such as examining the cost and benefits of its stimulus programme and possibly considering a future exit from its ultra-easy policy, Masayoshi Amamiya, a nominee for BOJ deputy governor, said on Monday.

"Japan's banking system remains stable now. But the environment surrounding financial institutions is becoming more severe," Amamiya, currently the BOJ's executive director, told a confirmation hearing in the lower house of parliament.
