TORONTO, Aug 19 (Reuters) - The Canadian dollar weakened to a four-day low against its U.S. counterpart on Monday, despite increasing oil prices, as the greenback rallied broadly on rising global risk appetite.
The U.S. dollar .DXY strengthened against a basket of currencies as risk sentiment gradually improved after a week of turmoil on hopes that major central banks would look to launch fresh stimulus measures to lift their sluggish economies.
"The U.S. dollar is up across the board today so this seems to be just a broad based dollar rally that's weakened the Canadian dollar," said Blake Jespersen, managing director of foreign exchange sales at BMO Capital Markets.
At 3:06 p.m. (1906 GMT), the Canadian dollar CAD=D4 was trading 0.5% lower at 1.3325 to the greenback, or 75.05 U.S. cents. The currency touched its weakest intraday level since last Thursday at 1.3332.
Meanwhile, the price of oil, one of Canada's major exports, was up after a weekend attack on a Saudi oil facility by Yemen's Houthi forces and as traders looked for signs that top economies would take measures to counteract a global slowdown. U.S. crude oil futures CLc1 settled 2.4% higher at $56.21 a barrel.
manufacturing sales data for June is due on Tuesday, with a Reuters poll forecasting a 1.7% decrease, which could help guide expectations about the Bank of Canada's interest rate decision.
Canadian government bond prices were lower across the yield curve in sympathy with U.S. Treasuries. The two-year CA2YT=RR fell 4.5 Canadian cents to yield 1.359% and the 10-year CA10YT=RR was down 14 Canadian cents to yield 1.178%.
On Thursday, the 10-year yield touched its lowest level since October 2016 at 1.083%.
