What it means
The bank's best-known job is monetary policy. It sets a target for the overnight rate, the rate at which banks lend to each other for a single night, and that target feeds through to the prime rate commercial banks charge their own customers.
Decisions are announced on a published calendar of scheduled dates each year. Its policy framework is built around an inflation target, agreed periodically with the federal government and long set near the middle of a 1% to 3% range.
When inflation runs above that zone the bank tends to raise rates to cool demand, and when it runs below the zone it tends to cut them. Monetary policy is not the bank's only function.
It designs and issues banknotes, oversees major payment systems, manages the federal government's debt issuance programme and holds foreign exchange reserves. It does not supervise individual banks, which in Canada is the responsibility of a separate federal regulator.
For a business the practical link is loan pricing. Most Canadian commercial borrowing is quoted as the prime rate plus a negotiated spread, so a change in the policy rate reaches interest cost on floating facilities within weeks.
A nuance that trips people up is the gap between the policy rate and the rates they actually pay. Mortgage and term loan rates also follow bond yields and lender funding costs, so they can move earlier than a policy decision or even against it.
One further point helps when reading the bank's communications. Every decision comes with a short statement, and at some meetings a fuller report setting out the outlook for growth and inflation.
Reading that statement rather than the headline usually tells a business more about what is likely to come next.
In practice
Real-world examples.
Example
A Vancouver manufacturer with a C$5,000,000 floating loan models a 1% rise in the policy rate, finds it would add C$50,000 of annual interest, and fixes half the balance to protect its covenant headroom.
Example
A Canadian exporter watches the policy announcement because a surprise cut tends to weaken the Canadian dollar, which raises the home-currency value of its US sales. It schedules its hedging decisions around the published decision dates.
Example
A retail chain's finance team uses the bank's published inflation outlook when setting next year's wage and rent assumptions, rather than simply extrapolating last year's cost increases. Anchoring the budget to a published outlook also makes the assumptions easier to defend at the board meeting.
Formula
Calculation
Annual interest on a floating facility = principal x (prime rate + contractual spread). Suppose a company has a C$2,000,000 operating line priced at prime plus 1.5%, and the prime rate stands at 5.0% when the budget is set. The all-in rate is 5.0% + 1.5% = 6.5%, so annual interest is C$2,000,000 x 0.065 = C$130,000. If the central bank raises its policy rate by 0.5% and lenders move prime to 5.5%, the all-in rate becomes 7.0% and annual interest becomes C$2,000,000 x 0.07 = C$140,000. The same borrowing now costs C$10,000 more a year, with no change in the amount drawn.Case study
Seen in the real world.
Northern Pine Millwork is a fictional Canadian joinery business used here as an illustrative case. It had financed an expansion with a C$3,000,000 floating facility at prime plus 2%, on the unstated assumption that rates would stay where they were.
When the policy rate rose over several consecutive meetings, the illustrative company's interest cost climbed by more than C$100,000 a year and its interest cover covenant came close to breaching. The owners had budgeted carefully for the expansion but not for the cost of the money funding it.
Their response was to split future borrowing: two thirds fixed through an interest rate swap and one third left floating, with a standing page in the board pack showing the cost of a further 1% rise. The invented case is a reminder that a central bank policy rate is a business planning assumption, not background news. Had the board modelled a two percentage point rise before signing the facility, it would have fixed part of the debt at the outset.
Watch out
Common mistakes.
- Believing the Bank of Canada sets mortgage and business loan rates directly, when it sets a policy target that lenders then pass through at their own spreads.
- Assuming the bank also supervises individual banks, when prudential supervision sits with a separate federal regulator.
- Budgeting floating interest cost at the current rate for a whole year with no sensitivity for a move in either direction.
Questions
People also ask.
What is the overnight rate target?
It is the rate the bank wants banks to charge each other for lending overnight, and it anchors short-term borrowing costs across the economy.
How does a rate decision reach a small business?
Usually through the prime rate, because most operating lines and many term loans are priced as prime plus a negotiated spread.
Does the bank control the exchange rate?
No, the Canadian dollar floats, although policy decisions and interest rate differences strongly influence where it trades.
