There are two parts to that answer.
The first thing is that, most of the time, inflation is caused primarily by international pressures. However, I want to stress the importance of keeping inflation expectations well anchored on our target, because if we don't, when those pressures moderate, inflation will not go down. Conversely, if those expectations are well anchored on the target, we will see a decrease.
The other aspect of inflation—and this has more to do with your question—relates to domestic pressures. Right now, the economy is in excess demand. The overall economy has fully recovered from the pandemic, and measures that further contribute to demand will exacerbate excess demand. In that case, we would have to raise interest rates further or we wouldn't be able to lower the inflation rate to reach our target. Inflation affects every Canadian's household budget, so it's very important for all Canadians that inflation remain anchored on the target.
