The Key Factors Affecting Mortgage Rates

The entire long-term cost of financing the purchase of a property is significantly influenced by mortgage interest rates. Mortgage borrowers aim for the lowest mortgage interest rates feasible, on the one hand. The interest rates that mortgage lenders charge, however, are how they must control their risk. Only customers with the best credit histories are eligible for the lowest mortgage interest rates.

While a borrower’s financial situation influences the interest rate that will be charged on a loan, economic conditions and governmental monetary policy have an impact on the entire range of mortgage rates. There are five main elements at work, and each of them in some way reflects the fundamentals of supply and demand.

Even though some of the underlying causes are complicated, knowing these concepts helps you to understand why you are now paying the interest rates you are and how they could change in the future.


For mortgage lenders, the continuous increase in prices brought on by inflation is a key component in the economy as a whole. Over time, inflation reduces the buying power of money. In order to ensure that their interest returns constitute a true net profit, mortgage lenders typically must keep interest rates at a level that is at least sufficient to counteract the loss of buying power due to inflation.

When yearly inflation is 2% but mortgage rates are 5%, for instance, the true return on a loan in terms of the buying power of the money the lender receives back is only 3%. As a result, mortgage lenders closely track the rate of inflation and modify their rates as necessary.


Mortgage rates are influenced by economic growth metrics like GDP and the employment rate. Higher salaries and more spending by consumers, especially those looking for mortgage loans to buy homes, are two effects of economic expansion. That’s advantageous for a nation’s economy, but the increase in demand for mortgages as a whole often results in higher mortgage rates. The cause is because lenders can only lend so much money.

On the contrary, this happens with a declining economy. The loss in employment and salaries results in a reduction in the demand for mortgages, which pressures mortgage lenders to provide lower interest rates.


One of the most significant factors affecting the economy generally and interest rates particularly, including mortgage rates, is the monetary policy that the Federal Reserve Bank pursues.

The particular interest rates in the mortgage market are not determined by the Federal Reserve. But it has a big influence on the interest rates accessible to the borrowing public when it sets the Fed Funds rate and modifies the money supply upward or downward.

In general, as the money supply expands, rates tend to decline whereas as it tightens, rates tend to rise.


Mortgage-backed securities (MBSs) are sold as investment products by banks and investment companies. To attract buyers, the yields on offer from these debt securities must be sufficiently high.

The fact that corporate and government bonds both provide competitive long-term fixed-income investments is a factor in this equation. The returns offered by MBSs are influenced by the money you can make on these rival financial options. The general state of the bigger bond market has an indirect impact on the interest rates charged by mortgage lenders. For MBSs to compete in the overall debt security market, lenders must produce enough returns.

The 10-Year Treasury bond yield is one commonly used government-bond benchmark to which mortgage lenders routinely tie their interest rates. As opposed to government bonds, where repayment is completely assured, MBS sellers typically have to provide higher returns.


Mortgage rates are also impacted by housing market trends and conditions. When there are fewer new construction or resale houses available, the reduction in home purchases causes a decline in the demand for mortgages, which drives interest rates lower.

An increase in consumers choosing to rent rather than buy a house is a recent trend that has lowered rates as well. These shifts in consumer demand and housing supply have an impact on the rates that mortgage lenders set for their loans.

Rates on mortgages are governed by the basic laws of supply and demand. A number of variables are involved, including inflation, economic expansion, the Federal Reserve’s monetary policy, and the health of the bond and housing markets. Naturally, a borrower’s financial situation will also have an impact on the interest rate they receive, so try to maintain the best situation for yourself.
