Scott Bessent is the CEO and founder of the investment company Key Square Group and has previously, among other things, been the head of George Soros' asset management company.
"He will help me initiate a new golden age for the USA", Trump writes on his platform Truth Social.
Bessent has backed Trump during the election campaign and the incoming president has called him "one of the most brilliant men on Wall Street."
"Scott is generally respected as one of the world's leading international investors and geopolitical and economic strategist", Trump writes.
Dismissed by Musk
Bessent, 62, was however dismissed by Trump friend Elon Musk last week for not being innovative enough, or for being too "business-as-usual", as Musk put it in English.
The future finance minister will be responsible for implementing Trump's economic plan. Trump has, among other things, promised tax cuts and a tougher stance on trade policy, not least towards China.
Bessent has previously stated that he decided to support Trump, among other things, due to promises of cuts in the state apparatus aimed at tackling the USA's national debt.
"Project 2025" Profile
Trump is also nominating Russel Vought to once again become the head of the White House's powerful Office of Management and Budget (OMB).
Vought, who also headed OMB when Trump was in the White House previously, was involved in the election campaign in developing the ultra-conservative action plan "Project 2025", which, among other things, pointed out measures to strengthen Trump's power after an election victory.
The Democrats made criticism of "Project 2025" a main issue and claimed that it posed a threat to democracy. The Trump campaign, on the other hand, emphasized that it had no connection to the plan.
Trump is also nominating Congresswoman Lori Chavez-DeRemer to become Labor Minister and Scott Turner, a former professional in American NFL football, to become Housing Minister.
