"The king of hedge funds" is worried about Trump's tariff policy, but optimistic that the US economy will return to "the path of business."

Known as the "king of hedge funds," Ken Griffin, founder of the well-known hedge fund Citadel Investment Group, expressed concerns about the potential tariff policies that Trump may introduce, but now that Trump is returning to the White House, he believes that the US economy will return to "business principles." On Monday, Griffin stated that tariffs - a core principle of Trump's economic agenda - are a "slippery slope" that may be profitable in the short term but could harm the ability of US companies to compete globally in the long term. Griffin said, "I am very concerned about the President's willingness to use tariffs as a trade policy issue." Earlier this year, Griffin called Trump's tariff policy "regrettable," but he believes that the Trump administration will benefit the market. However, Griffin also pointed out that in the next four years, US companies will "return" to creating jobs, expanding businesses, and the economy, rather than having to deal with excessive regulation. In a wide-ranging discussion on Monday involving topics such as politics, investments, and immigration, the 56-year-old billionaire also said that he believes the US government continues to overspend, and he hopes that the Trump administration can reduce the size of the government. Griffin is becoming increasingly outspoken about his views on US political issues, advocating for low taxes and a free market agenda, and criticizing the Democratic Party for being too soft on crime. Griffin predicted last month at the Saudi Future Investment Initiative that Trump would win the election, and according to data from the campaign finance tracking group OpenSecrets, he donated over $100 million to pro-Republican political action committees in this election cycle. Many major donors have flocked to Trump in the late stages of the campaign, expressing reservations about his policies, personality, and legal troubles. In his speech on Monday, Griffin also expressed reservations about Trump's promise to remove millions of undocumented immigrants. He said that the government needs to formulate a more detailed immigration policy. Regarding mass deportation, Griffin said, "I don't know how to do that, whether for humanitarian reasons or for economic reasons. I think we need to develop a more thoughtful immigration policy, not just expel millions of Americans." He said that when it comes to "those who come to our country, contribute to our economy, and try to settle down in the US," he doesn't understand how the government can deport these people. According to the Bloomberg Billionaires Index, Griffin founded Citadel Investment Group in 1990 and has since built the company into a $65 billion giant, with an estimated personal wealth of $42.2 billion. Multi-strategy hedge funds like Citadel Investments rely on teams of traders betting across asset classes to generate stable returns. The surging demand for such products has sparked an unprecedented talent war in the industry. When asked about his best investment, Griffin mentioned the investment in people that made his company the most profitable hedge fund in the world. Griffin said, "The best investment I've ever made is investing in people. Nothing compares to it. You find a very smart, very motivated, and creative person, and then you support them 110%. There is nothing better than this kind of investment."
