The dollar rose against other currencies on Thursday, after briefly falling following Federal Reserve (Fed) Chairman Jerome Powell's announcement of a change in central bank policy vis-à-vis other currencies. against its inflation target.

"It seems to me that we are witnessing a classic case of 'buying the rumor, selling the news', or the opposite in the case of the dollar", underlines Craig Erlam of the broker Oanda, recalling that the change in monetary policy was widely anticipated by investors.

The Fed's decision to tolerate a rise in inflation above 2% is unlikely to make a big difference at present, since inflation is well below this target and rates are expected to remain down for a long time.

The dollar was up 0.2% to 93.2370, according to the ICE Dollar Index, which measures the evolution of the greenback against a basket of currencies. ICE had fallen to a week low of 92.417 shortly after Jerome Powell's intervention.
