A Brief Primer on Monetary Policy
Before describing the decision-making process, it will be helpful to provide
some background information on monetary policy itself.
Monetary policy in Canada has one objective—achieving and maintaining a
low, stable and predictable level of ination. This objective was formalized
in 1991 in an ination-control agreement between the federal government
and the Bank of Canada. The agreement identies a specic target for the
rate of ination—the midpoint of an ination-control range—as well as the
price index that is to be used to measure ination. Since 1995, the target
level for the ination rate has been 2 per cent (within a control range of 1 to
3per cent), as measured by the 12-month rate of change in the total con-
sumer price index.
Achieving a targeted ination rate may seem like a rather narrow objective—
a notion that will be revisited later—but experience has shown that this is the
best contribution monetary policy can make to the economic well-being of
Canadians. The greater certainty that low and stable ination provides
regarding the future path of prices allows households and businesses to
make more-informed spending and investment decisions, and minimizes the
inequitable impact of unexpected movements in the overall level of prices.
Keeping ination low, stable and predictable is a means to an end, not an
end in itself.
Under normal circumstances, this objective is pursued using a single policy
instrument or tool—changes to the overnight rate of interest.

The Bank sets
the overnight rate, which determines the rates at which banks and other
selected agents are able to borrow and lend at the shortest end of the yield
curve. Movements in the overnight rate also set in motion a number of other
changes throughout the economy that ultimately affect the rate of ination.
The transmission mechanism
Through the monetary policy transmission mechanism (Figure 1), changes
in the overnight interest rate inuence the interest rates that the market sets
on securities further out the yield curve, as well as rates on securities with
different risk and liquidity characteristics (for example, bonds, equities and
mortgages). These changes also inuence the exchange rate—the external
value of the Canadian dollar. The resulting movements in asset prices, in
turn, affect aggregate demand in the Canadian economy by inuencing the
spending and investment decisions of both Canadians and foreigners.
If strong aggregate demand pressures appeared likely to push output
above the economy’s capacity limits and lift ination above the 2 per cent
target, the Bank would respond by raising the overnight rate. This would
put upward pressure on other interest rates and the exchange rate, all other
things being equal, dampening aggregate demand and stabilizing ination
at the 2 per cent target. The process would be reversed if demand were too
weak and ination seemed likely to fall below 2 per cent. The overnight rate
would be lowered, boosting aggregate demand and increasing ination. It is
important to note that the Bank takes a symmetric approach to the pursuit
of its monetary policy objective; it is as concerned about undershooting
2 In exceptional circumstances, central banks have several other, unconventional monetary policy tools
at their disposal, including quantitative easing, credit easing and conditional commitments concerning
the path of future interest rates (sometimes referred to as “guidance”). These tools have been used by
a number of central banks in the past ve years as a means of providing additional monetary policy
stimulus once the overnight interest rate approached zero and hit its effective lower bound. For more
information, see Bank of Canada (2009) and Santor and Suchanek (2013).
