London. The euro sank against the dollar on Thursday on stubborn worries over the Greek debt crisis after the nation warned again that it could appeal for aid to the International Monetary Fund, AFP reported.
In early morning trade, the European single currency tumbled to 1.3648 dollars. It later stood at 1.3673 dollars, down from 1.3735 late in New York on Wednesday.
"All this talk of a bail-out plan had been buoying the euro but the market now seems to realise that talking about a bail-out and delivering one are two totally different things," said CMC Markets analyst Michael Hewson.
"German constitution and EU law prohibit bail-outs and Greece's threat to go IMF merely highlights these problems more starkly.
He added: "The euro will continue to remain under pressure as any type of bail-out plan could be illegal under EU law."
Greek Prime Minister George Papandreou on Wednesday refused to rule out an appeal for aid to the IMF if European backing is insufficient to resolve its debt crisis.
