The dollar largely held onto the previous session's gains in early Asian trade on Friday, while sterling edged up on news that Britain could leave the European Union without a Brexit deal at a slightly later date.
Against a basket of key rival currencies, the dollar was about 0.1 percent lower at 96.394.
The index had recovered three-quarters of a percent overnight after falling to a more than six-week low on Wednesday on news the Federal Reserve had abandoned plans to raise rates this year.
British Prime Minister Theresa May on Friday welcomed the European Union's decision to delay Brexit, saying that lawmakers in the British parliament now had clear choices about what to do next.
Sterling rose one-sixth of a percent to $1.3126. It had retraced sharp losses overnight, when it touched as low as $1.3004.
