The Canadian dollar depreciated for a fifth consecutive week last week, weighed down by gloomy employment data from the US and a concomitant crude slump.The sentiment that pushed West Texas Intermediate crude above $73 last month evaporated during the week as the Labor Department announced that there was a further decline in the US job market in June, with unemployment running at 9.5 per cent after an additional 467,000 job losses.Yanick Desnoyers, assistant chief economist in Montreal at National Bank Financial, a unit of Canada's sixth-biggest bank, told Bloomberg that the Canadian dollar traded down over the week as concerns mounted over oil demand. Crude is Canada's biggest export. "It should weaken a bit further in the short run because commodity prices are falling," he predicted, envisaging that crude will trade at C$1.19 to the dollar by the year's end.The US dollar proved more resilient to the gloomy jobs data last week, closing up against 11 of the 16 most actively traded currencies tracked by Bloomberg. The loonie, as the Canadian dollar is known, languished in the bottom six performers, along with the Australian and New Zealand dollars.
