SoftBank's Masayoshi Son put forward the idea of a US-Japan sovereign wealth fund.

According to the Financial Times, citing three informed sources, SoftBank Group founder Masayoshi Son has proposed the idea of establishing a US-Japan sovereign wealth fund aimed at making large-scale investments in the technology and infrastructure sectors. The report stated that Son has already discussed the plan with US Treasury Secretary Scott Besent, but it has not been formally proposed yet. A source told the Financial Times that for this joint fund to be effective, it may require an initial capital of around $300 billion and be equipped with high leverage. According to the report, the fund would be jointly owned and managed by the US Treasury Department and the Japanese Ministry of Finance, with both sides holding significant stakes. The fund may also be open to limited partners, providing opportunities for individual investors in the US and Japan to participate. A source familiar with the situation told the publication that Besent has been looking for non-tax revenue sources, and this fund could potentially provide a solution.
