USD exchange rate today in the world

The US dollar fell after US President Donald Trump called on Federal Reserve Governor Lisa Cook to resign, but later pared losses as minutes from the Fed's latest meeting showed only two policymakers supported a rate cut last month.

Trump cited allegations made by a political ally about mortgages Cook held in Michigan and Georgia as part of his effort to gain influence over the US central bank. According to the Wall Street Journal, President Trump has also told aides that he is considering firing Cook.

Trump has repeatedly criticized Fed Chairman Jerome Powell for being too slow to cut interest rates, and traders expect him to replace him with a more dovish figure when his term ends. However, Powell is likely to remain on the Board of Governors, which would limit the number of appointments Trump can make and hamper his plans to make the Fed more dovish.

The US dollar recovered slightly after the minutes of the Fed meeting on July 29 showed that the two members who opposed the decision to keep interest rates unchanged last month did not receive more support from other members in cutting interest rates.

The euro rose 0.09% to $1.1657. The Japanese yen strengthened 0.32% against the dollar to 147.2 JPY/USD.

This week, traders are focused on whether Powell will counter market expectations for a rate cut at the Fed’s September 16-17 meeting when he speaks at the Jackson Hole conference on Friday, following the weak July jobs report. Powell has said he was hesitant to cut rates because he was concerned that President Trump’s tariffs would push up inflation this summer. July consumer inflation data showed the impact of tariffs was limited, but higher-than-expected producer price inflation has dampened expectations for more rate cuts this year.

The New Zealand dollar fell 1.12% to $0.5826, its lowest in four months, after the country's central bank cut its policy rate by 25 basis points to a three-year low of 3.00% and signaled further cuts could be possible in the near term due to concerns about growth risks at home and abroad.

The Swedish krona rose 0.1% to 9.59 after the central bank kept its key interest rate unchanged at 2.00% as expected.

The pound fell 0.3 percent to $1.3449 after UK inflation rose to an 18-month high in July, but not enough to impact Bank of England (BoE) policy.
