Steven Mnuchin, who was treasury secretary in the Trump administration, is planning to start an investment fund that is expected to raise money from sovereign wealth funds in the Persian Gulf region and other investors, two people familiar with the project said.

The fund, based in Washington, would focus on areas including financial technology and entertainment, among other potential sectors, the people said. Mnuchin, who worked as a Wall Street executive and film producer before joining the Trump administration, has begun hiring for the endeavor. The people familiar with the matter spoke on the condition of anonymity to discuss planning that has not been made public.

The United Arab Emirates, Kuwait, Qatar and Saudi Arabia control some of the region’s largest investment funds, according to the Sovereign Wealth Fund Institute, which tracks these types of funds.

Mnuchin did not immediately respond to a request for comment.

Mnuchin frequently traveled to the Middle East throughout the Trump administration, most often in relation to treasury’s mandate to combat terrorism financing abroad. In the waning weeks of the Trump administration, as Washington reeled from the Jan. 6 riot at the U.S. Capitol and questions swirled around whether Trump’s Cabinet would try to remove him from power, Mnuchin was on a diplomatic swing through the Middle East and Africa, visiting Sudan, Egypt, Israel, the United Arab Emirates, Saudi Arabia and Qatar. He had planned to visit Kuwait as well, but cut the trip short in the aftermath of the riot.

Mnuchin also visited the region in October to promote commercial ties in the wake of the Abraham Accords, which normalized relations between Israel and several Arab states. Mnuchin and Jared Kushner, former president Donald Trump’s adviser and son-in-law, also helped put together the Bahrain conference in 2019 that helped lead to the Abraham Accords.

Mnuchin traveled to Saudi Arabia and met with Crown Prince Mohammed bin Salman in October 2018, even as the Saudi royal was widely suspected of ordering the brutal killing just weeks earlier of journalist Jamal Khashoggi. The CIA later concluded that Mohammed ordered the assassination.

Trump was a strong supporter of the crown prince, viewing Saudi Arabia and allied states like the United Arab Emirates as crucial partners in an effort to counter Iran in the region. Trump blocked congressional efforts to stop arms sales to Saudi Arabia and pushed through an arms sale to the UAE despite bipartisan opposition in Congress.

Trump also pulled out of a multilateral nuclear deal with Iran that had been negotiated by the Obama administration, and pursued a “maximum pressure” campaign targeting Iran’s few remaining links to the international financial system. The renewed sanctions helped devastate the Iranian economy and raised concerns over Iran’s ability to import humanitarian goods in the midst of the coronavirus pandemic.

The Trump administration also formally backed the conduct of the UAE and Saudi Arabia in Yemen’s civil war, garnering criticism from Democrats and human rights groups that it was overlooking attacks on civilians and a deepening humanitarian crisis.

“Hundreds of thousands of people in Yemen have died for the Trump administration’s relationship with the Saudi and UAE governments," said Mark Weisbrot, an economist at the Center for Economic and Policy Research. “It would be terrible if Mnuchin or other Trump officials were to cash in on this now.”

Though it is unclear if Mnuchin will seek funds from the Saudi or UAE governments, his planned investment effort, coming so soon after leaving office, raises concerns over whether Trump administration policy was influenced by Mnuchin’s future pursuits, an ethics expert said.

“The fact that there were policies that were favorable to countries that now might benefit him in a business matter is troubling, and does raise questions about whether even the prospect of future business interests might have impacted decision-making, even if there were no specific plans in place,” said Noah Bookbinder, president of Citizens for Responsibility and Ethics in Washington, a nonprofit watchdog group.

Following in the footsteps of other former senior government officials, Mnuchin has put himself on the speaking circuit since leaving the Treasury Department, and plans to charge $250,000 to speak in person, Bloomberg News reported last week.

Mnuchin’s successor, Treasury Secretary Janet Yellen, earned more than $7 million in speaking fees over two years from major banks and corporations, according to her financial disclosure form.
