The dollar fell to its lowest level since a near rate rise on Friday after Federal Reserve Chairperson Jerome Powell all but signalled an end to the Fed's fight against inflation. Data showed the dollar hit a 52-week low against a basket of currencies, extending a recent decline caused by expectations of interest rate cuts in the coming months. A change in policy could change the direction of capital flows in global markets. However, a weaker dollar tends to help US companies sell goods and services overseas.
