Thank you. That's an excellent question, and a perennial one in Canada.
We have many sectors. We have many regions. The sectors often line up with the regions, so very often the issue arises as to whether it's desirable to have a flexible exchange rate, for example, which is an important part of Canada's monetary policy system.
This relates to the last comment that Scott made. The problem—and perhaps I can steal a phrase and say that it's just an inconvenient truth—is that we have different sectors of the economy, different regions of the economy, and they are subject to very different shocks. The best examples would be if you want to think about the west or maybe now the west and the east being exposed to world commodity prices, energy prices in particular, and producers and exporters of energy, whereas central Canada is largely a user of energy. Well, when world energy prices rise, that is going to tend to be very good for those energy-producing regions and sectors, and it's going to be bad for those sectors and regions in the economy that are net users.
That's just a fact of life. But then the question is what kind of monetary policy do you want? The current system has an inflation targeting system where we allow the exchange rate to rise and fall in response to those shocks, and we certainly have seen those adjustments in the past. Unless you're going to have multiple currency areas across Canada, and I don't think anybody is seriously suggesting that, politically or economically, then you have to deal with the fact that we are a single-currency union.
I didn't think this discussion was going to get to Europe, but it could get there very quickly.
We accept the fact that we are a single-currency union with regions with very different shocks and we deal with it. We do deal with it. That doesn't mean that there is not pain and adjustment that happens in response to these shocks, but it's one thing to recognize those shocks and it's quite another to believe that monetary policy can do something about it.
As long as we are going to have a single-currency area called Canada, the Bank of Canada needs to have a single monetary policy for Canada as a whole. So it tends to look at, and tends to be driven by, national averages as opposed to regional developments. I believe that's appropriate.
