The policy interest rate, also known as the overnight rate, is the most important tool the Bank of Canada uses to manage inflation, borrowing, and spending across the country.
It represents the rate at which major financial institutions lend and borrow funds from each other overnight. This single rate acts as the foundation for most lending rates in Canada, including mortgages, personal loans, and credit lines.
How the Policy Rate Works
- When the Bank of Canada raises the rate, borrowing becomes more expensive. This slows down spending and helps reduce inflation.
- When the Bank cuts the rate, borrowing becomes cheaper. This encourages households and businesses to spend and invest.
This process of influencing the economy through rate adjustments is known as monetary transmission.
The Policy Rate vs. Prime Rate
Most Canadians experience the policy rate through the prime rate, which banks use to price variable loans and lines of credit.
| Term | Definition | Example |
|---|---|---|
| Policy Rate | Set by the Bank of Canada | 2.50% |
| Prime Rate | Base rate used by commercial banks | ~4.70% |
| Variable Mortgage | Prime plus or minus a margin | ~5.20% |
Typically, when the BoC changes the policy rate by 0.25%, banks adjust their prime rates accordingly within a few days.
Real-World Impact
- Variable-rate mortgages: Your monthly payment changes almost immediately after a rate change.
- Fixed-rate mortgages: More closely tied to bond yields, but still influenced by BoC policy direction.
- Savings and GICs: Interest offered by banks on deposits often rises or falls along with the policy rate.
- Business financing: Companies experience higher or lower costs for lines of credit and loans.
Why Each 0.25% Move Matters
A single quarter-point move in the policy rate can impact billions of dollars in consumer and business debt. That’s why economists, investors, and homeowners closely monitor every BoC rate decision.
