The dollar held its recent gains in early Asia trading on Wednesday as investors looked towards a key Federal Reserve policy meeting to see if it would reinforce growing market expectations for earlier rate rises next year. The dollar index which measures the greenback against six major peers was at 96.557, having gained 0.5% so far this week in choppy trading. It is testing last week"s 96.954, which would be a two-week top. The dollar"s gains have been broad-based. The euro last traded at $1.1265, not far from $1.1184 hit in November, which was its lowest in over a year. The pound languished at $1.13326 as Britain grapples with rising cases of the Omicron variant of the new coronavirus. read more But the Federal Reserve meeting due to wrap up later in the day stood out as the centrepiece of a week full of central bank meetings. Kim Mundy, currency strategist at CBA, said currency markets were "taking a tiny break from Omicron" even though it was "very much bubbling away in the background." "It"s hard for it to be the dominant focus when you"ve got the FOMC, and the Bank of England and European Central Bank lining up to make policy decisions," said Mundy.

Mundy said a figure at the lower end of that range could cause some short-term dollar weakness. The yen softened slightly to 113.78 per dollar, continuing a weakening trend. The safe-haven currency had firmed sharply in late November, when the Omicron variant first emerged. The Australian dollar was little changed at $0.7107, and the Canadian dollar was weaker at 1.2854 per dollar, having been bruised by oil prices coming off recent peaks. Investors in the Australian currency were keeping a close eye on Chinese economic activity data due later in the day, given that China is Australia"s largest trading partner.
