TORONTO, Nov 10 (Reuters) - The Canadian dollar briefly rose above parity with its U.S. counterpart on Wednesday, helped by stronger-than-expected U.S. data and firm commodity prices.
The currency reversed earlier weakness briefly seen after Canada posted an unexpectedly large trade deficit. [ID:nN10169238]
The Canadian dollar CAD=D4 hit a session high of 99.94 Canadian cents to the U.S. dollar, or $1.0006, up from around C$1.0050 to the U.S. dollar, or 99.50 U.S. cents.
"We're seeing overall U.S. dollar weakness across the board," said Darren Richardson, senior corporate dealer at CanadianForex.
"Combine that with the stronger commodity prices this morning, that's been the main driver behind the Canadian dollar force."
Gold rose to hold around $1,400, recovering from its choppiest trading session in six months the day before, as concerns about euro zone debt reignited safe-haven buying, while oil prices had bounced over $87 a barrel. [GOL/] [O/R]
Data showed initial claims for U.S. jobless benefits hit a four-month low last week, while the trade gap narrowed more than expected in September. The encouraging data helped supported riskier assets.
"It helped traders continue to add risk and give them the confidence to buy Canadian," added Richardson.
He cautioned however, that further Canadian dollar strength in the session is unlikely with significant support for the greenback at 99.77 Canadian cents to the U.S. dollar, and strong demand by corporate Canada to buy the U.S. currency at its current low levels.
By 10:00 a.m. (1500 GMT), the Canadian dollar CAD=D4 eased to C$1.0028 to the U.S. dollar, or 99.72 U.S. cents, still up from C$1.0074 to the U.S. dollar, or 99.27 U.S. cents, at Tuesday's close.
Canada's Remembrance Day and U.S. Veterans Day holidays, which will close bond markets, may also lighten trade.
Market players are also monitoring developments ahead of the Group of 20 leaders' summit on Thursday and Friday in Seoul, and simmering tensions over economic policy between Beijing and Washington have been front and center.
Few investors expect any significant agreement on currencies or trade imbalances to emerge from the meet. A G20 official told Reuters the communique would call for "flexible exchange rate movement", and would not provide neither numerical targets nor details on external imbalances. [ID:nASN000037]
Canada's currency will likely hover around parity with the U.S. dollar in the near term, but could weaken in early 2011 as markets realize the U.S. Federal Reserve is not "flooding the world with greenbacks," according to a report from CIBC World Markets. [ID:nN09115367]
Canadian government bond prices were higher across the curve as investors awaited the auction of C$3 billion of 2-year Government of Canada bonds and $16 billion of 30-year U.S. Treasuries later on Wednesday.
The two-year bond CA2YT=RR was up 8 Canadian cents to yield 1.570 percent, while the 10-year bond CA10YT=RR gained 13 Canadian cents to yield 2.961 percent. (Additional reporting by Ka Yan Ng; editing by Jeffrey Hodgson)
