U.S. President Donald Trump has discussed firing Federal Reserve Chairman Jerome Powell, Bloomberg reported on Saturday.

Mr. Trump’s frustration with the U.S. central bank chief intensified after this week’s interest rate increase and months of stockmarket losses, the news agency said, citing four unidentified people familiar with the matter. Mr. Trump has talked privately about firing Mr. Powell many times in the past few days, it said, citing two of the people.

The Fed raised interest rates on Wednesday for the fourth time in 2018, and signalled “some further gradual” rate increases ahead.
