According to CoinMeta and The Wall Street Journal, sources familiar with the matter have revealed that since Janet Yellen took on the role of Federal Reserve Chair, President Donald Trump has spoken with her on multiple occasions, breaking with previous communication practices between the president and central bank governors. These sources indicate that Trump's calls with Yellen were sometimes frequent, with multiple conversations within a few days, while at other times there was a long period of silence between them. Some of these individuals mentioned that Trump sought Yellen's opinions on a range of issues, including the impact of the Iran conflict and the rapid development of artificial intelligence on the economy. It is not yet clear whether Trump and Yellen have discussed monetary policy. One source insisted that the president never brought up interest rates during their conversations. Other sources noted that Yellen often expressed optimistic views about the economy in her talks with Trump, which align with her public statements. Trump has told his political allies that he considers Yellen to be an important external economic advisor. A person who heard Trump speak firsthand revealed that Trump would often praise the appearance of the Federal Reserve Chair on television. The relationship between Trump and Yellen may raise concerns regarding the independence of the Federal Reserve.
