Despite the initialoptimism over the rescue plan, traders said the currency market remained sceptical.
"There is a lot of scepticism in the market, and that seems to be evident by the way the euro has rebounded, the pound, Canadian and Aussie dollars too," said Jon Gencher, director of FX sales at BMO Capital Markets in Toronto.
"The market is waiting to see how this whole thing is going to pan out."
In this country, ANZ bank said today that risk sentiment had improved, sending the NZ and Australian dollars higher.
The kiwi finished last week with a one-way move against a backdrop of a poorly performing US dollar, ANZ said.
