In our cost estimate, we assume that the Bank of Canada monetary policy will ensure that inflation returns to its target range of 2% in the medium term by successively increasing interest rates, but if that were to not be the case, the cost would quite clearly be higher if inflation was not brought under control.
We assume that the monetary policy of the bank will be sufficiently robust to return to inflation of around 2%, but if that were to not be the case, again, costs would go up.
