Chinese exports unexpectedly fell the most in two years in December, while imports also contracted, pointing to further weakness in the world's second largest economy in 2019 and deteriorating global demand.

"If Chinese growth is slowing as fast as it appears then the path is lower for the Canadian dollar," said Adam Button, chief currency analyst at ForexLive.

Canada is running a current account deficit and exports many commodities, including oil, so its economy could be hurt if the global economy slows.

US crude oil futures settled 2.1 percent lower at $50.51 a barrel, taking a pause after a recent rally, while stocks also lost ground.

At 3:41 p.m. EST (2041 GMT), the Canadian dollar was trading 0.1 percent lower at 1.3273 to the greenback, or 75.34 US cents.

The currency, which has rebounded 1.5 percent since the beginning of 2019 after falling 7.8 percent last year, touched its weakest intraday level since Jan. 8 at 1.3297.

"You can't get a sustained rally in the Canadian dollar until you get stability in housing," Button said.

Canadian home prices fell in December for the third consecutive month, data showed. The Teranet-National Bank Composite House Price Index was off 0.3 percent last month from November.

Canada's inflation report for December is due on Friday.

Canadian government bond prices were mixed across the yield curve, with the two-year up 1 Canadian cent to yield 1.886 percent and the 10-year falling 5 Canadian cents to yield 1.965 percent.
