5 Year Government of Canada Bond Yield Explained
The 5-year government bond is a low-risk investment available to Canadians, so low-risk that it is also called a security. The Canadian government backs bonds, and the coupon yield is paid regularly at a set percentage of the bond’s face value.
In this article, we cover what a government bond is, the factors that determine bond yields, why the 5-year bond is important and how it affects mortgage rates in Canada.
Key Takeaways
- Bonds are investment instruments issued by the Canadian government to raise funds for operations and to repay its debts.
- A bond’s yield measures the value it returns over its life.
- 5-Year fixed-rate mortgages generally follow 5-year government bonds, with an additional 1-2% spread over the bond yield.

What Is a Government Bond?
A government bond is a security, meaning the buyer lends the government money in exchange for a guarantee that the face value will be repaid when the bond matures. Government bonds are issued to fund government operations and cover year-end budget deficits. Bonds are considered secure investments, particularly in Canada, because the government is unlikely to default on bond repayments.
What Is a Government Bond Yield?
The buyer will receive interest payments on the amount lent to the government for the bond’s term (e.g., 5 years). Yield is the bond’s annual return, calculated as a simple coupon yield (a set percentage of the bond’s face value paid at regular time intervals, e.g. 10% a year) or the more complex yield to maturity (YTM).
Unlike coupon yield, a bond’s YTM is the sum of all interest payments you would receive over the bond’s life, plus any gains or losses from buying the bond at a discount or premium, providing an overall view of the bond’s lifetime yield.
For example, if you bought a bond at a $1,000 face value with a 20% coupon, you would receive $200 per year until maturity, at which point you would also be repaid the face value ($1,000).
However, if you sold the bond, its price may have changed. If the bond is now worth $800, it sells at a discount. Likewise, at $1,200, the bond would sell at a premium. However, the coupon percentage remains the same.
The buyer of the bond, whether they purchased it for $800 or $1,200, would still receive $200 in annual interest based on the bond’s original face value. The bond yield will change based on the coupon amount as a percentage of the new selling price. If you sell the bond for $800, the new yield is 25% ($200/$800). If you sell the bond for $1,200, the new yield is approximately 16.67% ($200/$1,200).
If all this sounds complicated, don’t worry. The key point is that a bond creates value over its life until maturity, and the yield measures how much value it creates.

Why Does the 5-Year Bond Yield Matter?
Bond yields are considered one of the safest investments because they are backed by the Canadian government. While government bonds can have maturities ranging from 2 to 30 years, the 5-year bond is significant for Canadian homeowners with 5-year fixed-rate mortgages, as mortgage interest rates follow 5-year bond yields.
Bond yields directly affect borrowing costs, as yields with comparable maturities determine fixed-rate mortgages with the same term (e.g., 3-year bond yields set 3-year fixed rates). 5-year bond yields are also often used to gauge the state of the Canadian economy.
What Causes the 5-Year Bond Yield To Change?
The government sets a bond’s initial interest rate to incentivize purchases. However, bond yields are ultimately set by the market, which is influenced by domestic and international factors. Inflation expectations, monetary policy decisions, and economic indicators influence the direction of bond yields, which in turn move accordingly.
Inflation is the most significant influencer on bond yields. Bond yields tend to rise when inflation expectations exceed the 2% target and may fall when inflation is expected to be below the target.
Bond yields typically move in line with interest rates when monetary policy is implemented. When the central bank raises interest rates, bond yields usually increase. When the interest rate is lowered, bond yields may also decrease to reflect the lower cost of borrowing. GDP growth, employment data and other economic indicators can also impact bond yields. Since Canada is a close trading partner of the United States, Canadian bond yields are closely linked to changes in the US bond market.
Two forces have mattered more than the others through 2026, and neither is domestic. The first is the price of oil, which drives inflation expectations: the blockade of the Strait of Hormuz and the partial closure of Red Sea shipping routes kept energy costs elevated from late July onward. The second is the supply of government debt itself. Most major economies are running large deficits, which means more bonds to sell, and governments are now competing for investor capital with corporations borrowing heavily to fund data centres and other artificial intelligence infrastructure. When there is more debt on offer and no more appetite to absorb it, sellers have to offer a higher yield to find a buyer. That is why Canadian yields have risen even in months when Canadian data was soft.
Are Variable Mortgages Affected by 5-Year Bonds in Canada?
Variable mortgages are not affected by changes to 5-year bond yields. Instead, they are directly influenced by changes to the Prime Rate. Prime rates are set based on the Bank of Canada’s target for the overnight rate. When the Bank of Canada announces changes to its policy interest rate, the variable rate will increase or decrease alongside each announcement.
5-Year Bond Yield Forecast
The 5-year Government of Canada bond yield has spent 2026 climbing. It started the year near 2.72% in late February, held in a narrow band through the spring, then moved higher from July onward as oil prices and United States Treasury yields rose together. It reached about 3.18% in early July, eased to roughly 3.13% by July 10, and returned to 3.18%-3.23% in the first week of August. On August 21 it touched a 12-month high near 3.36%, closed at 3.26% on August 26, and has since settled around 3.35%, close to a 52-week high. Lenders raised fixed mortgage rates twice within 5 days in August as those moves went through, and have not walked that pricing back.
The shape of the curve has changed as well, and this is the part most coverage misses. The 1-year Government of Canada yield sat near 2.67% in August, leaving the 5-year more than 60 basis points above it. For several years the opposite was true, with shorter-term yields sitting above longer-term ones. That normalization is why a 3-year fixed rate now prices below a 5-year fixed rate at most lenders, and it is a straightforward reason to compare terms rather than default to the 5-year.
Looking ahead, the Bank of Canada’s Market Participants Survey for the second quarter of 2026 puts the median forecast for the 5-year yield at 3.15% by the end of 2026 and 3.10% by the end of 2027. Forecasts from the Big 6 Banks for the fourth quarter of 2026 range from 2.95% to 3.30%. The yield is currently trading above most of those numbers, which means either the forecasts get revised up or the yield comes back down, and the answer depends mostly on inflation and on how much government debt markets are asked to absorb.
For borrowers, the practical implication is that fixed-rate pricing has drifted structurally higher this year rather than temporarily. Waiting for fixed rates to fall is a weaker bet than it has been at any point in this cycle. Lower inflation, easing geopolitical tension, or reduced expectations of central bank increases could still bring yields down, but most of those forces sit outside Canada. A rate hold is the practical protection if you are shopping while yields are moving.
Frequently Asked Questions (FAQ) on Government of Canada (GoC) Bond Yields
How do Government bond yields relate to mortgage rates?
In simple terms, fixed mortgage rates follow bond yields, with a spread of around 1-2% added to cover the lender’s risk. Consequently, if the current 5-year bond yield is 3.35%, we can expect fixed mortgage rates to be around 4.35-5.35%.
How do bond yields affect mortgage rates?
Bonds, specifically Canada Mortgage Bonds (CMBs), are considered mortgage-backed securities (MBS). Bonds are debt securities issued by governments, such as the Government of Canada, to fund growth and projects, including homebuilding and homebuying activity. Institutional investors and pension funds purchase government bonds and receive interest payments until maturity.
If interest rates rise in Canada, bond prices usually fall, even if coupon rates remain unchanged, leading to higher bond yields. On the other hand, if interest rates in Canada decline, bond prices typically rise while coupon rates remain constant, resulting in lower yields on those bonds.
The 5-year fixed mortgage rates in Canada follow 5-year Canadian bond yields plus a spread set by the banks. Bond yields can shift direction based on market sentiment and economic factors, such as inflation and employment. While this won’t change your rate if you’re already locked into a 5-year fixed rate, it can change interest rates for new 5-year fixed mortgages. Mortgage rates follow bond yields, with an additional 1-2% spread to cover lenders’ risk premium and funding costs.
What is an inverted yield curve?
An inverted yield curve slopes downward, indicating that short-term interest rates exceed long-term rates. Such a yield curve typically reflects periods when investors expect economic weakness and lower yields on longer-maturity bonds in the future.
Canada’s curve is no longer inverted. It spent much of the period from 2022 to 2025 inverted, and has since normalised: as of August 2026, the 1-year Government of Canada yield sat near 2.67% while the 5-year sat more than 60 basis points higher, which is the conventional upward-sloping shape you would expect in a stable or growing economy. For borrowers, the practical consequence is that shorter fixed terms now price below longer ones, reversing the pattern of the tightening cycle.
How did the inverted yield curve affect Canada’s mortgage market?
In 2022, Canada’s yield curve inverted, with short-term government bonds yielding more than long-term bonds. This led to higher mortgage interest rates, as mortgage rates follow bond yields, and it made shorter fixed terms more expensive than longer ones. Now that the curve has normalised, that relationship has reversed.
The Bank of Canada sets only short-term interest rates (the target for the overnight rate) in Canada. It does not influence long-term rates, which are driven by bond supply and demand. When bond yields rise due to changes in bond prices, funding mortgages becomes more costly for lenders, prompting them to raise their advertised rates to maintain profitability.
How are Government of Canada Bonds issued?
The Government of Canada issues fixed-income securities, such as bonds, in certificate form through securities auctions. You can typically purchase government bonds from any Canadian Big Bank or investment institution, or through a broker. The Canadian government issues bonds continuously and sets rates based on current economic conditions.
Should I get a fixed-rate mortgage if rates continue to rise?
Whether a fixed-rate mortgage suits you when yields are rising depends on your budget and your tolerance for payment changes rather than on a forecast. Because fixed rates follow the bond yield curve, securing a rate before yields move further protects you if they keep climbing, and a rate hold does that at no cost while you shop. The trade-off is that you give up the benefit if yields fall instead.
The best place to start is by exploring the available fixed-rate mortgages in Canada and determining what you qualify for.
Final Thoughts
Bonds are financial instruments that governments use to help raise capital to operate or fund infrastructure growth. They’re considered low-risk, secure investments because they pay a fixed rate of return for their duration and are backed by the government.
Bonds also offer liquidity, as they can be easily bought and sold in secondary markets. Understanding how bond yields affect mortgage rates is helpful, as the two are closely related.
