Japanese Institutional Investors Drive Strong Demand

Demand for the yen-denominated bond sale was strong among domestic and international investors, with Japanese institutional investors playing a central role 3

3

. Life-insurance funds and pension plans in Japan have very large long-duration yen-denominated liabilities and have been short of high-quality assets to match them since the Bank of Japan ended its negative-rate policy 1

1

. A high-grade AA corporate issuing in size at long tenors solves both sides of the equation for these institutional investors 1

1

. The choice of Mizuho alongside Bank of America and Morgan Stanley is conventional for a high-profile debut Samurai trade, as Mizuho retains the most extensive corporate-Japan bond-distribution network of any local underwriter 1

. Amazon is also reportedly preparing a debut Swiss franc bond offering to fund its own AI-related investments, with BNP Paribas, Deutsche Bank, and JPMorgan Chase mandated for a six-part debt offering with maturities ranging from three to 25 years 2
