What makes mortgage rates fluctuate

Lenders have to generate sufficient yields for MBSs to make them competitive in the total debt security market. One frequently used government-bond benchmark to which mortgage lenders often peg their interest rates is the Year Treasury bond yield.

Trends and conditions in the housing market also affect mortgage rates. When fewer homes are being built or offered for resale, the decline in home purchasing leads to a decline in the demand for mortgages and pushes interest rates downward. A recent trend that has also applied downward pressure to rates is an increasing number of consumers opting to rent rather than buy a home.

Such changes in the availability of homes and consumer demand affect the levels at which mortgage lenders set loan rates. Mortgage rates are tied to the basic rules of supply and demand. Of course, a borrower's financial health will also affect the interest rate they receive, so do your best to keep your's as healthy as possible.

The rise and fall of interest rates is very difficult to predict. Why interest rates change is reflected through economic growth, monetary policy and fiscal policy.

The most important factor in determining why interest rates change is the supply of funds available from lenders and the demand from borrowers. In a period when many people are borrowing money to buy houses, banks need to have funds available to lend. Institutional investors have more investment opportunities so this source of funds is more expensive and the banks might have to pay higher interest rates.

Mortgage rates will then go up to reflect the higher cost of bank mortgage funding if funding is hard to obtain. The same logic applies to the credit markets as a whole. In a booming economy, many firms need to borrow funds to expand their plants, finance inventories and even acquire other firms. Consumers might be buying cars and houses. That need keeps the demand for capital at a high level and interest rates higher than they otherwise might be.

The way governments spend their money and finance their endeavors is called fiscal policy. Specifically, the Federal Reserve is a key component in controlling interest rates and reining inflation by adjusting the supply of money in the economy. If economic growth generates too much inflation, the risk to the economy is that purchasing power deteriorates.

To prevent a costly drop in the purchasing power of money, the Federal Reserve buys a calculated amount of Treasury bonds on the open market to inject money into the economy.

The effect of additional money helps decrease interest rates to more sustainable levels. Mortgage rates also fluctuate according to certain economic indicators. For example, the federal funds rate is the interest rate banks pay when they borrow from each other, usually overnight, to meet federally mandated reserves that must be stored in banks. The federal funds rate forms the basis on which banks determine their interest rates. Other indicators may include both the Consumer Price Index and the Producer Price Index, which measure changes in prices on products purchased by consumers and producers.

Mortgage interest rates are also influenced by developments in the real estate industry that help indicate the strength on the demand for mortgages.

For instance, mortgage lenders monitor the construction and sale of new homes. If sales and building activity increases, lenders expect the demand for mortgage borrowing to increase, pushing mortgage rates upward. Conversely, declining sales and construction of new homes indicates a weaker demand for new mortgages, driving interest rates lower.
