FXStreet (Mumbai) - In an interview before Wednesday's ceremony to mark the company's debut on the Tokyo Stock Exchange, the newly privatized Japan Post Bank Co President Masatsugu Nagato, stated that bank could step up efforts to do away with Japanese government bonds and invest more funds into domestic and overseas equities to boost returns as a listed company. Mr. Nagato noted, "We have about 2 trillion yen (10.76 billion pounds) worth of Japanese equities now. Within risks allowed, we may increase them. We may also increase overseas equities." He also added, "Operation of our bank is constrained in many aspects, including a ban on lending. So one of the ways to increase revenue is to bolster investment portfolio management." Japan Post Bank Co.’s market debut on Wednesday marks Japan's biggest privatisation in 30 years. Meanwhile, the Japanese stocks rally could be partly attributed to the comments from Japan Post Bank Co.’s Chief Nagato, with the Nikkei 225 soaring over 2% so far.
