The Canadian dollar has appreciated more than 2 US cents against the greenback since Monday, from a low of C$1.0050 to a more than five-month high of C$0.9842 on Thursday, on the back of a huge cash injection by the European Central Bank, solid US labor market data and elevated oil prices. "A lot of clients have seen the improving US economic data, they've seen oil prices moving a lot higher and I think the Canadian dollar just becomes a much more attractive place to invest," said Blake Jespersen, managing director of foreign exchange sales at BMO Capital Markets. "I think sentiment has really changed this week towards the Canadian dollar, it's appreciated considerably against some of the major currencies, the yen, the euro. We're seeing a lot of money coming back into Canada." Domestic fourth quarter growth data due at 8:30 a.m. (1330 GMT) was expected to drive further direction for the Canadian currency. Analysts polled by Reuters predicted that Canadian economic growth came crashing down to reality to an annualized rate of 1.8 percent in the fourth quarter after a spurt in the third that was due largely to temporary factors. "It could have a modest impact on the currency no doubt, especially if it comes in a little weaker than expected I think you'd see a bit more aggressive profit taking on the back of that so we are definitely positioned that way," added Jespersen. He said resistance for the Canadian currency was in place around C$0.9850 and support was seen holding between C$0.9915-80. At 8:08 a.m., the Canadian dollar stood at C$0.9878 versus the US dollar, or $1.0123, down from Thursday's North American session finish at C$0.9859 versus the US dollar, or $1.0143. On the crosses, the Canadian dollar surged to a near 7-month high versus the yen after data showed persistent negative price pressures in Japan which are likely to keep the Bank of Japan's focus on monetary easing and undermine the currency. Canadian bond prices edged higher across the curve, with the two-year bond up 2 Canadian cents to yield 1.115 percent. The 10-year bond added 16 Canadian cents to yield 1.986 percent.
