The two are related. In our macroeconometric model, the oil prices have an important effect on determining the exchange rate. The way we project oil prices is through futures prices. Right now the futures indicate that oil prices are going to be relatively flat across the projection horizon, which also contributes to the fact that our exchange rate forecast for the Canadian dollar is relatively flat at around 76ยข U.S.
The other force, I think, that's acting a bit in the short term is the interest rate differential between Canada and the U.S., which is supposed to be slightly higher on the U.S. side compared to October. That has minor impacts, but really when you see a flat exchange rate, it's due to the flat commodity price outlook.
