President Donald Trump is ratcheting up pressure on the Federal Reserve to cut interest rates, accusing Fed Chair Jerome H. Powell of “playing politics” and of acting too slowly to respond to changes in the economy.

Traders boosted bets on Tuesday the Federal Reserve will start cutting its policy rate as soon as next month, as the White House said additional tariffs on imports from China will go into effect on Wednesday in a further escalation of trade hostilities that could slow the economy.

Traders expect the Federal Reserve to slash interest rates another five times this year as the US administration’s trade tariffs ignite fears of a global recession.
