The Driving Forces Behind Variable and Fixed Mortgage Rates

Understanding the factors behind both variable and fixed mortgage rates is essential for aligning with financial goals and preferences.

Variable Mortgage Rates

The primary driver of variable mortgage rates is the prime rate, which banks adjust based on the Bank of Canada’s overnight rate. This overnight rate is the interest rate at which major financial institutions lend and borrow funds from each other for one day. It’s a key tool used by the Bank of Canada to manage economic conditions. When the Bank of Canada raises or lowers the overnight rate to manage inflation, economic growth, or recession, the prime rate follows suit, which in turn impacts variable mortgage rates.

A few key economic indicators that influence these decisions include:

1. Inflation: Rising inflation typically prompts the Bank of Canada to increase the overnight

rate to help cool the economy.

2. Unemployment: High unemployment can encourage the Bank to lower rates in order to

stimulate economic activity and job growth.

3. GDP Growth: Strong GDP growth may push the Bank to raise rates to prevent the

economy from overheating.

Fixed Mortgage Rates:

Fixed mortgage rates, on the other hand are influenced by longer-term factors,

primarily government bond yields, particularly the 5-year bond yield. These yields reflect

the cost of long-term borrowing in the capital markets, serving as a benchmark for lenders. When bond yields rise, borrowing costs increase, which typically results in higher fixed mortgage rates. Conversely, when bond yields decrease, fixed mortgage rates tend to follow.

The economic outlook and expectations about inflation play a major role in shaping bond yields. If investors foresee higher inflation in the future, they may demand higher yields on bonds, leading to higher fixed mortgage rates. Additionally, global economic conditions, central bank policies, and market sentiment can all impact bond yields. Lenders also take into account their cost of funds, which includes the interest they pay on deposits and the cost of raising money in the capital markets. If these costs rise, lenders may raise fixed rates to maintain their profit margins.

Variable vs. Fixed Rates: Key Differences

While both variable and fixed rates are influenced by broader economic trends, they react in different ways:

Variable Rates: Tied to short-term interest rate movements, variable rates can offer savings if rates decrease, but they also come with the risk of higher payments if rates rise.

Fixed Rates: Driven by long-term economic outlooks and bond market conditions, fixed

rates provide stability and predictability, protecting borrowers from potential interest rate

increases over the life of their mortgage.

Choosing the Right Mortgage

Understanding these factors will help in choosing the mortgage option that best fits your financial situation, risk tolerance, and market outlook. Individuals who seek stability and predictability may be inclined to opt for fixed rates, while those willing to accept some risk for the potential of lower initial rates may prefer variable rates.
