President Donald Trump’s executive order to create a plan for a U.S. sovereign wealth fund would follow those of Norway, Saudi Arabia, China and others.

It is unclear how the United States, which already spends more money than it collects in taxes, would finance such a fund.

It’s not clear where the money to create the sovereign wealth fund is coming from, but Treasury Secretary Scott Bessent said the hope is to get it up within the next 12 months.
