When the Bank of Canada changes its policy interest rate, the impact extends far beyond the financial markets. It can influence mortgage payments, borrowing costs, savings, business investment, consumer spending, employment, financial markets and, ultimately, the cost of living.
The Bank of Canada uses its Target for the Overnight Rate as its primary monetary-policy tool. Its objective is to keep inflation at the 2% midpoint of a 1%–3% target range over the medium term.

What Happens When Interest Rates Rise?
When inflationary pressures are persistent or economic demand is too strong, the Bank may increase its policy rate. Higher interest rates generally make borrowing more expensive and encourage households and businesses to reduce spending — which helps moderate inflation over the medium term.
1.Mortgages and Borrowing
The most immediate impact is often felt by Canadians with variable-rate mortgages, lines of credit and other variable-rate loans. As financial institutions adjust their prime lending rates in response to the Bank of Canada's decision, borrowing costs can change quickly.
Fixed-rate mortgages do not automatically change when the Bank of Canada announces a rate decision. However, fixed rates are influenced by bond market yields and investor expectations — borrowers may face a different rate when their mortgage comes up for renewal.
Practical example
On a $500,000 variable-rate mortgage, a 1% increase in the interest rate translates to approximately $200–$250 more per month in interest costs.
2.Consumer Spending
Higher borrowing costs can cause households to postpone major purchases such as homes, vehicles and renovations. Credit-card balances and other forms of consumer debt can also become more expensive to carry.
This reduction in spending is an important part of the monetary-policy transmission process. By moderating demand, higher interest rates can help reduce inflationary pressure over time.
3.Savings and Deposits
Higher interest rates can benefit savers. Banks and other financial institutions may offer higher rates on savings accounts, GICs and other interest-bearing products.
The effect of higher rates is therefore not uniformly negative: borrowers generally face higher costs, while savers may receive higher returns.
4.Businesses and the Economy
Interest rates are equally important for Canadian businesses. Higher financing costs can make it more expensive for companies to purchase equipment, expand operations, acquire property or finance working capital.
Lower interest rates generally have the opposite effect — making financing more affordable and potentially encouraging business investment and broader economic activity.
5.Investments and Financial Markets
Interest-rate changes can influence stocks, bonds, real estate and other investments. Higher rates can put pressure on companies whose profits depend heavily on borrowing or whose valuations are particularly sensitive to the cost of capital.
At the same time, higher yields can make fixed-income investments more attractive relative to equities. Lower rates can support economic activity and may improve the attractiveness of risk assets, although the effect varies according to economic conditions and investor expectations.
6.Inflation and the Cost of Living
The ultimate purpose of changing the policy rate is not simply to make borrowing more expensive or cheaper — it is to help maintain price stability. The Bank of Canada estimates that monetary-policy actions take time to work through the economy.
The full effect on inflation typically occurs over six to eight quarters, which means the Bank must make decisions based on where inflation and the economy are expected to be in the future — not simply on current conditions.
Official target
The Bank of Canada targets inflation at 2% — the midpoint of a 1%–3% control range — over the medium term.
7.The Canadian Dollar
Interest-rate changes can also affect the Canadian dollar. Differences between Canadian and foreign interest rates can influence international capital flows and demand for Canadian-dollar assets.
Changes in the exchange rate can subsequently affect import prices, export competitiveness and businesses that buy or sell goods and services internationally.
What Does This Mean for You?
The impact depends greatly on your individual or business financial position. When evaluating the effect of an interest-rate change, consider:
- The amount and type of debt you carry (fixed vs. variable rate)
- Whether your mortgage has a fixed or variable rate
- When your mortgage is due for renewal
- Your level of savings and emergency liquidity
- Your investment mix (equities vs. fixed income)
- Your household or business cash flow
- Your exposure to the Canadian and U.S. dollars
- Your ability to withstand higher financing costs
The Bigger Picture
An interest-rate change does not affect everyone in the same way. A higher rate can increase the financial burden on borrowers while improving opportunities for savers; a lower rate can reduce borrowing costs while potentially reducing returns on interest-bearing savings.
Understanding this relationship is an important part of financial literacy — and can help Canadians make better-informed decisions about borrowing, saving, investing, retirement planning and business financing.
As of October 30, 2025, the Bank of Canada has held its target for the overnight rate steady at 2.25%. The Canadian prime rate currently stands at 4.45%. Variable-rate mortgages, HELOCs, and personal lines of credit are directly tied to this prime rate.
