Time up update my irregular series of graphs of oil price movements in currencies other than the USD:
The story of the first couple of months is pretty straightforward: oil prices fell in January and came back up in February, and there wasn't much in the way of significant exchange rate movements. By the end of February, we were pretty much where we were when the year started.
And then March hit, with important swings in both oil prices and in exchange rates. In the Euro zone, an appreciating currency attenuated much of the rise in oil prices, and oil was slightly cheaper on March 20 than it was on Jan 2. The even stronger appreciation of the yen means that oil prices in Japan are 7% lower than when the year began.
The CAD has been tracking the USD pretty closely over the past few months, but the recent drop in oil prices has been offset by a depreciating CAD. The net result is that CAD oil prices are still more than 5% higher than at the beginning of the year.
As long as forex markets peg the CAD to oil prices, the CAD value of oil exports should hold up.
