First of all, there's been a very wide range of risks to the real purchasing power of Canadians' savings, and I would suggest volatility in the inflation rate is near the bottom of the list compared to what's happened in financial markets, the value of assets, and so on.
But my more important response would be: where do Canadians get their savings in the first place? For most of us, you have to have a job that pays you enough to pay the bills, and then sock away a little bit of money. So in that regard, I think more of an emphasis on reducing unemployment—and increasing incomes from employment—would actually benefit Canadians' savings, because they'll have more money going into the bank.
Secondly, the nominal rates of interest are going to increase if the overall level of inflation increases as well, and that can have a benefit.
