The world of finance is an intricately interconnected web, where various factors influence one another. One such relationship exists between mortgage rates and bond yields. While bond yields might seem distant from the everyday life of a homeowner, they play a crucial role in determining interest rates. In this blog post, we will delve into the fascinating connection between mortgage rates and bond yields, helping you grasp the dynamics that impact your homeownership journey.

1. What are Bond Yields?

Before diving into their relationship, let’s understand what bond yields are. Bond yields represent the interest rate paid by governments or corporations on their debt securities, such as Treasury bonds. These yields fluctuate based on factors like economic conditions, inflation, and interest rate expectations. We often look up bond yields at this site.

2. The Inverse Relationship

The relationship between bond prices and mortgage rates is primarily an inverse one. When bond prices fall, the yield increases. When bond prices rise, the yields fall, this is the inverse relationaship. As bond prices go up the yield decreases, similarly if bond prices fall, their yields would increase. Mortgage rates track what happens to bond yields, rates also have an inverse relationship with bond prices. Tracking the direction of bond yields can help us guess and what we think will happen to mortgage rates in the future.

3. Mortgage Rates and the 5-Year Treasury Bond Yield

The 5-year bond yield is often considered a benchmark for mortgage rates. As it reflects the interest rate on 5-year Canadian government bonds, changes in this yield significantly influence mortgage rates. Especially since many Canadians primarily choose the 5 year term when choosing a fixed rate. The lender can match the duration of the mortgage with the bond yield to limit their interest rate risk. The difference between the bond yield and the mortgage rate is the spread the bank earns.

4. Impact of Economic Conditions

Economic conditions have a profound impact on both the interest rates and the government bond yields. In times of economic growth and stability, bond yields tend to rise as investors seek higher returns. Consequently, mortgage rates increase to attract lenders and account for inflation risks.

5. Influence of Central Banks

Central banks, such as the Bank of Canada, play a pivotal role in influencing bond yields. Through monetary policy, central banks can impact short-term interest rates, indirectly affecting longer-term bond yields.

6. Expectations of Inflation

Anticipations of inflation can significantly impact bond yields. When inflation is expected to rise, bond investors demand higher yields to offset the eroding value of their fixed returns.

7. Global Events and Uncertainty

Global events and geopolitical uncertainty can lead investors to seek safe-haven assets like government bonds. Consequently, increased demand for bonds drives their prices higher, lowering their yields, and eventually causing a dip in mortgage rates.

8. The Impact on Homebuyers

For potential homebuyers, understanding the relationship between bond yields and mortgage rates can be advantageous. It enables them to make informed decisions on the best time to lock in a mortgage rate, taking advantage of low rates when bond yields are favorable.


The intricate dance between bond yields and mortgage rates showcases the complexities of the financial world. As bond yields fluctuate in response to economic conditions, inflation, and central bank actions, mortgage rates follow suit. This knowledge empowers homebuyers to navigate the real estate market with greater awareness, making well-timed decisions that can result in more favorable mortgage terms. Ultimately, staying informed about these financial interconnections can lead to a smoother and more financially prudent homeownership journey.
