SINGAPORE, Nov 28 — The US dollar was heading for its worst weekly performance since late July on Friday as traders ramped up bets for further monetary easing from the Federal Reserve next month, while liquidity was thinned by the US Thanksgiving holiday.

The dollar index, which measures the greenback’s strength against a basket of six major peers, was last trading up 0.1 per cent at 99.624, recovering some ground after five days of decline pushed it to its worst one-week loss since July 21.
