Meanwhile, the dollar index was trading down 0.03 per cent at 95.75 against a basket of six currencies in early trade.
Overseas, the US dollar held steady against its major rivals in early trade with its near-term fortunes riding on whether US jobs data will rekindle expectations for the Federal Reserve to raise interest rates this year.
