What Is the Canada 5-Year Bond Yield and Why Does It Affect Mortgage Rates?
If you have been following mortgage rates in Canada, you have likely heard experts talk about how fixed mortgage rates are affected by bond yields, particularly the Canada 5-year bond yield. News headlines often say things like:
“Bond yields are rising, which could push mortgage rates higher.”
“The 5-year Government of Canada bond yield has fallen, creating room for lower fixed mortgage rates.”
But what exactly is a bond yield? Why does it matter to homeowners? And why do mortgage lenders care so much about the Canada 5-year bond?
The answer is simple: a 5-year mortgage is the most common term for a residential mortgage in Canada, and the Canada 5-year bond yield is the single most important benchmark used to price most 5-year fixed mortgage rates in Canada.
Understanding how bond yields work can help you better understand mortgage rate changes, predict future rate movements, and make more informed borrowing decisions.
Quick Answer: What Is a Bond Yield?
A bond yield is the return investors earn from owning a bond.
When investors buy Government of Canada bonds, they are lending money to the federal government in exchange for interest payments and repayment of their principal at maturity.
The value of a bond can rise and fall based on investor demand, economic conditions, inflation expectations, and interest rate forecasts. What an investor earns on a bond depends on what they pay for the bond. The interest coupon is fixed and does not change, so if the bond price goes up the yield earned from that fixed interest coupon payment will be lower.
Because lenders use bond yields as a benchmark when setting fixed mortgage rates, changes in bond yields often lead to changes in Canadian mortgage rates.
What Is the Canada 5-Year Bond Yield?
The Canada 5-year bond yield represents the return investors demand for lending money to the Government of Canada for five years.
It serves as a key benchmark for:
- 5-year fixed mortgage rates
- Government borrowing costs
- Financial market expectations
- Future interest rate forecasts
Since the majority of Canadian borrowers choose 5-year mortgage terms, the 5-year bond is the most relevant benchmark for pricing fixed-rate mortgages. Note that a 3-year mortgage is priced off the 3-year Government of Canada bond, but 5-year mortgages are more common.
Why Does the Canada 5-Year Bond Yield Affect Mortgage Rates?
The simplest answer is that mortgage lenders need enough revenue to cover their costs and leave a profit margin. One of the key costs for a mortgage lender is their cost to fund mortgages.
The Canada 5-year bond yield acts as a baseline funding benchmark. When investors demand a higher yield to purchase a bond, the bond yields increase, resulting in lenders’ funding costs also increasing. When bond yields decrease, lenders’ funding costs decrease.
As a result:
- Higher bond yields usually lead to higher fixed mortgage rates.
- Lower bond yields usually lead to lower fixed mortgage rates.
This is why mortgage professionals watch the bond market every day.
How Are Bond Yields Determined?
Bond yields are set by supply and demand in the bond market. They are determined by investors who buy and sell the bonds in the bond market. Note that Government of Canada bond yields are not set directly by the government.
If investors are eager to buy bonds, thereby increasing demand, bond prices will rise and bond yields will fall.
If investor demand for bonds goes down and/or they sell bonds, thereby lowering demand, bond prices will fall and bond yields will rise.
This is the inverse relationship between price and yield that is one of the most important concepts in fixed-income investing.
Bond Prices and Yields Move Opposite Each Other

Who Buys Government of Canada Bonds?
Several types of institutional investors that are active in the fixed-income markets purchase Government of Canada bonds. These include pension funds, banks, insurance companies, investment funds, central banks, and others. These investors may be based in Canada or in markets around the world. Government bonds tend to form a core component of their investment strategies and represent a stable, relatively safe, liquid, and regular investment return.
What Causes Bond Yields to Rise?
Several factors can push bond yields higher, including:
- Inflation expectations
- Strong economic growth
- Government borrowing
1. Inflation Expectations
Inflation is often the biggest driver of bond yields. Investors want compensation for inflation that may reduce the future purchasing power of their money.
If inflation is expected to remain high, bond yields tend to rise and fixed mortgage rates often rise.
2. Strong Economic Growth
A strong economy often leads investors to expect higher inflation and future interest rate increases. These expectations can push bond yields higher.
3. Government Borrowing
When governments borrow more, go deeper into debt, and issue more bonds, increased supply can lead investors to demand higher yields. The old economic relationship between supply and demand has a significant impact on prices.
What Causes Bond Yields to Fall?
Several factors can push bond yields lower, including:
- Economic slowdowns
- Expected Bank of Canada rate cuts
- Flight to safety
1. Economic Slowdowns
Bond yields often fall when investors become concerned about economic growth. One of the most common reasons for this concern is economic slowdowns. Weak economic growth often reduces inflation pressure. Lower inflation expectations can push bond yields lower.
2. Expected Bank of Canada Rate Cuts
When investors believe the Bank of Canada will lower interest rates in the future, bond yields often fall ahead of the actual rate cuts. The bond market is forward looking, anticipating future events. Bond yields will usually move up or down well in advance of a rate move by a central bank.
3. Flight to Safety
During periods of uncertainty, investors frequently buy government bonds because they are considered lower risk investments. The resulting increase in demand for bonds pushes their prices higher and bond yields lower.
How Are Fixed Mortgage Rates Priced?
Mortgage lenders have pricing formulas for mortgages. These formulas start with their own cost of financing, which is usually the five-year bond plus a spread. The spread represents the margin investors demand to invest directly in the financial institution. A large, highly rated bank can fund itself at a lower spread than a smaller independent mortgage lender.
Some lenders are also able to fund some of their mortgages in the capital markets (rather than on their own balance sheets), most commonly via mortgage-backed securities (MBS). The largest capital markets funding programs for mortgages in Canada are sponsored by CMHC — the NHA MBS program and the Canada Mortgage Bond (CMB) program. In the case of capital markets funded mortgages, the funding cost for the lender would be the bond yield plus the spread that investors require to invest in the MBS.
Mortgage Pricing Formula
A simplified mortgage pricing formula looks like this:
Mortgage Rate = 5-Year Bond Yield + Lender Spread
The lender spread covers:
- Funding costs
- Administration and regulatory costs
- Credit risks
- Hedging costs to manage interest rate risk
- Profit margin
For example:
| Component | Rate |
|---|---|
| Canada 5-Year Bond Yield | 3.30% |
| Funding Costs | 0.50% |
| Admin/regulatory | 0.15% |
| Credit Risk | 0.10% |
| Hedging/Interest Rate Risk | 0.15% |
| Profit Margin | 0.25% |
| Total | 4.45% |
What Is the Mortgage Spread?
The mortgage spread is the difference between the bond yield and the mortgage rate. In the example above the mortgage spread is 1.15% (often called 115 basis points — note that 100 basis points is equal to 1.0%), which is the difference between the mortgage rate of 4.45% and the bond yield of 3.30%.
The spread changes constantly. The treasury departments at mortgage lenders and banks monitor this daily. They adjust the spread to respond to market pricing and dynamics but also to competitive pressures. During periods of intense competition, lenders may shrink spreads and lower mortgage rates. During uncertain economic conditions, lenders may widen spreads to protect themselves from risk. This explains why mortgage rates sometimes move differently than bond yields.
Why Can Mortgage Rates Change When the Bank of Canada Does Nothing?
This is one of the most common questions borrowers ask.
Fixed Mortgage Rates vs. Variable Mortgage Rates
Many Canadians assume all mortgage rates follow the Bank of Canada. This is not correct.
Variable mortgage rates are directly impacted by the rates set by the Bank of Canada, but fixed mortgage rates are based on bond yields.
Fixed mortgage rates are primarily influenced by:
- Canada 5-year bond yields
- Inflation expectations
- Economic forecasts
- Mortgage lender competition
Variable mortgage rates are primarily influenced by:
- Bank of Canada overnight rate
- Prime rate
- Mortgage lender competition
Because bond markets are forward-looking, fixed mortgage rates may rise or fall months before the Bank of Canada changes interest rates.
