The dollar index reversed earlier gains to trade near 0.2% lower and below 93.3 on Thursday after President Trump suggested delaying November presidential election scheduled, claiming fraud in mail-in voting and as data showed the US economy contracted more than expected and jobless claims rose for a second week. Earlier in the session, the dollar traded slightly higher but close to levels not seen since mid-2018 as investors' risk appetite dampened amid a worldwide spike in coronavirus cases. For the month, the dollar will probably suffer its worst decline in a decade with a 4.2% dive.
