As lenders prepare for stricter rules governing capital levels, Mitsubishi UFJ Financial Group Inc. said it has hired a senior researcher from the Bank of Japan to analyze the nation's financial industry.

Mitsubishi UFJ Morgan Stanley Securities Co., a brokerage unit of Japan's biggest lender, has appointed Junsuke Senoguchi as senior analyst, spokesman Susumu Taroura said.

Senoguchi, 44, worked in the BOJ's financial systems and bank examination department, where he studied international banking rules.

Nomura Holdings Inc. and Mizuho Financial Group Inc. are among financial firms that are examining how more stringent capital and liquidity requirements being developed by global regulators may affect their business.

Some of the rules have yet to be defined, including which firms will be regarded as global systemically important financial institutions, or G-SIFIs, that may be subject to more onerous capital standards.

"How the new regulations will affect the financial sector is an important theme," Taroura said.

It is the first time for the brokerage to assign an analyst to cover the overall financial sector rather than individual firms, he added. The BOJ's financial systems and bank examination department is responsible for monitoring and reviewing Japanese banks' credit costs and capital.
