TORONTO, Nov 11 (Reuters) - Canada's currency eased against the U.S. dollar on Thursday but shot up against the euro in thin trading, as fresh European debt fears spurred investors to seek solace in the greenback.
Yields on 10-year Irish bonds rose to a record high over comparable German debt as some investors worried that Ireland wouldn't be able to cut spending as planned and may require a bailout, sending the euro tumbling against the U.S. currency.
The prospect of a fresh European debt crisis prompted many traders to dump riskier assets and move their capital back into U.S. dollars.
"What's really going on is euro. Euro is getting sold, hard," said Firas Askari, head of foreign exchange trading at BMO Capital Markets. "Canada is following the euro story but it's not selling off as much as it should."
The Group of 20 meeting in South Korea -- which is trying to sort out disagreements over currency policy -- produced little market direction as leaders struggled to agree on meaningful action to rebuild the global economy as the crisis erupted in Ireland. [ID:nTOE6AA0BQ]
The Canadian dollar CAD=D4 closed the North American session at C$1.0032 to the U.S. dollar, or 99.68 U.S. cents, down from its finish exactly at par on Wednesday.
Against the euro, the Canadian dollar hit a high C$1.3688 or 73.05 euro cents, its strongest level since September.
Earlier the currency had been supported by reports of strong Chinese growth, which boosted commodity prices, including copper, which raced to a record high. [MET/L]
It hit an overnight session high of 99.77 Canadian cents to the U.S. dollar, or $1.002, briefly breaking a key resistance level at 99.80 Canadian cents to reach its best level since April.
"It's holding in quite significantly and it's going to draw the attention of some money managers," said Askari.
He noted there was little liquidity on Thursday, given Canada's Remembrance Day and U.S. Veteran's Day holidays which have closed bond markets. Most action on the crosses was Canadian dollar buying against the euro, he added.
Askari pointed to 99.31 Canadian cents to the greenback, the 2010 high reached in April, as the next key resistance level for the Canadian dollar. On the support side, he was eyeing C$1.0080.
Many market watchers, however, were hesitant to call parity again in the near term.
Adam Cole, global head of FX strategy at RBC Capital Markets, said he couldn't single out a short term catalyst that would bring Canada back to one-for-one footing.
"But it's probably only a question of time before we do because the fundamental backdrop in Canada is still a very strong one," he said. (Editing by Jeffrey Hodgson)
