Warren Buffett's Berkshire Hathaway plans to conduct its second yen bond issuance in the global market this year, sparking market speculation that the company is seeking to increase its investments in Japan. Berkshire Hathaway has hired Bank of America Securities and SMBC Nikko Securities to issue yen-denominated senior unsecured bonds. The company has been a regular issuer of yen notes since 2019, with the last issuance of such bonds in April. The company's fundraising plan is closely watched by stock market investors, as Buffett's previous purchase of shares in a Japanese trading company boosted the Nikkei 225 index to a historic high. Buffett stated in his February shareholder letter that Berkshire's majority of investments in Japanese companies have been funded through yen bond issuances. (Global Market Report)
