The Canadian dollar weakened against its U.S. counterpart on Wednesday to lag many other “G10” currencies, as oil prices fell and a 13-month high for the greenback pressured emerging markets and global stocks.

The price of oil, one of Canada’s major exports, was pressured by a weakening global economic growth outlook and data showing rising U.S. crude inventories.

U.S. crude oil futures settled 3 percent lower at $65.01 a barrel.

Oil was an “obvious catalyst” for the weaker Canadian dollar said Mark McCormick, North American head of FX strategy at TD Securities.

The currency has also become more sensitive over the past month to movement in stock prices, McCormick said.

U.S. stocks sold off on concerns over a strengthening U.S. dollar, Turkey’s currency crisis and global trade tensions.

Canada exports many commodities and runs a current account deficit, so its economy could be hurt if the flow of trade or capital slows.
