TOKYO, March 31 (Reuters) - Japanese regional lenders will be well able to weather even "large" losses on their foreign bond portfolios thanks to strong capital buffers, a senior banking regulator official said, rebuffing concerns fuelled by U.S. banking woes. "Overseas media seem to be focusing on Japanese regional banks in association with the SVB collapse, but I'd like to emphasise that they are completely different," he told Reuters in an interview. Analysts at SMBC Nikko Securities calculated unrealized foreign bond losses at over 70 listed Japanese regional banks totalling 1.4 trillion yen ($10.6 billion) at the end of last year, the worst in decades for global bond markets. "It is true that unrealized losses on foreign bond holdings at some regional banks are large, but the banks have enough capital buffers even when such losses are taken into account," Yashiki said. He also said he saw no immediate need to review Japan's regulatory framework as Japanese banks have grown resilient with significantly improved asset quality.
