SoftBank founder Masayoshi Son proposed the establishment of a US-Japan sovereign wealth fund.

The Financial Times, citing three sources, reported that SoftBank founder Masayoshi Son proposed establishing a US-Japan sovereign wealth fund aimed at making large-scale investments in technology and infrastructure. The report stated that Son had discussed the plan with US Treasury Secretary Janet Yellen, but has not formally proposed a plan yet. One source revealed that the joint fund may require approximately $300 billion in initial capital and leverage to operate effectively. The fund is said to be jointly owned and operated by the US Treasury and the Japanese Finance Ministry, each holding significant stakes. The fund may also be opened to limited partners, potentially providing an opportunity for retail investors in Japan and the US to participate. A source stated that Yellen has been looking for non-tax sources of fiscal revenue, and this fund may provide a solution.
