For most people, the biggest purchase they will ever make is their home. In fact though, their mortgage and the mortgage interest rates it connotes are a larger purchase than their home. In single loan term, the amount you pay to cover the mortgage interest rate cost is more often than not more than what you paid for your house. Reducing even a fraction of your mortgage interest rates can save you a great deal of money on your mortgage.

The rise and fall of mortgage interest rates have become erratic during the past 20 years. As a rule of thumb, mortgage interest rates go up when the economy is strong and stock prices rise. On the other hand, if economy weakens, mortgage interest rates go down.

In todays market, the mortgage interest rates are much lower than they were in the mid-1980s to the 90s. But within the next year or two, financial experts have come up with predictions mostly outlining the rise of mortgage interest rates.

A sad fact however, is that with mortgage interest rates, there are no certainties and no guarantees. No one can really tell whether or not mortgage interest rates will rise over a period of time. The current mortgage interest rate that you are charged right now is something that your banker or broker cannot control. Often, loans with unattractive mortgage interest rates are sold to FannieMae or FreddieMac which in turn, sell these loans to the secondary market.

Mortgage investors purchase these secondary market loans with mortgage interest rates that are undesirable to the regular homebuyer. These investors are actually the ones who set the standards in mortgage interest rates.

When news of a growing economy erupts, the Fed will raise the mortgage interest rates in an effort to slow down economic growth and lower stock prices. As a result, the investors would demand higher mortgage interest rates from their lenders. To sell their loans, lenders will increase their mortgage interest rate yields. This drives mortgage interest rates even higher.

When the economy goes down on the other hand, the same thing happens with mortgage interest rates, but in reverse. The Feds will cut down the mortgage interest rates in order to bring the economy back to life. Investors will start buying more bonds while the mortgage interest rates are low. Demand grows and loan sellers offer their products with lower mortgage interest rates. Thus consumers will be able to get loans for decreased mortgage interest rates.

Mortgage interest rates are based on a financial instrument called index. LIBOR (London Interbank Offered Rate) is among the most common indices that mortgage interest rates are based on. Other mortgage interest rate indices are 1-Year Treasury Security, Prime, 6-Month CD, and the 11th District Cost of Funds (COFI). These indices for mortgage interest rates are subject to the financial conditions of the market.

Loans are offered with different mortgage interest rates. Take for example a traditional 30-year mortgage. This type of loan involves a fixed mortgage interest rate. The mortgage interest rate of a 30-year mortgage is higher than that of a 15-year mortgage.

Other alternative programs and payment plans for your loans can some difference on your mortgage interest rate. An adjustable rate mortgage initially has lower mortgage interest rates compared to fixed rates.

So basically, the effect of economics on mortgage interest rates is also counteracted by the type of mortgage you choose to take.

Why do bank rate mortgages vary? What makes the interest rates of these bank rate mortgages rise? What makes those of bank rate mortgages fall? These questions race through our minds whenever we are faced with a financial situation that requires us to understand a little bit more about bank rate mortgages.

The answer is simple enough. Bank rate mortgages are moved by several factors that are different from but are somehow connected with each other. Not surprisingly, one of these factors that affect the movement of bank rate mortgages is you the consumer.

Bank mortgage rate money come from any number of sources. Bank mortgage rate money may come from deposits at banks and brokerages. Most bank mortgage rate money comes from investors who comprise the collective term, capital markets. These capital markets are where the purchase of debt instruments like bonds and bank rate mortgages are done.

To attract investors, sellers of bank rate mortgages and bonds in these capital markets compete with one another. This is done by providing their consumers with a variety of products, such as bonds and bank rate mortgage. These bank rate mortgage products have varying levels of risks and gains over given periods of time. In turn, these offerings compete with other investments which possess certain similarities in terms of performance. These include US Treasuries, corporate bonds, foreign bonds, bank rate mortgages, and others.

The bank rate mortgage investors act like typical consumers. That is, like you, they want two opposing things: low payments on their bank rate mortgages and high returns on investments. The demands of these investors play a significant role in moving the yields of the bank rate mortgage markets. The marketplace for bank rate mortgages is crowded because investors literally have hundreds of places to put their money into.

Sellers of various products like bank rate mortgages compete with others for those investor dollars. Demands for specific products, e.g. bank rate mortgages, rise and fall according to the changes made in the investment strategies. For instance, if demand for bank rate mortgages falls, a change needs to be done to attract investors again. And this is usually done by raising interest rates on bank rate mortgages.

Then again, bank rate mortgages are never that simple. The market makers of bank rate mortgages do not have the investors alone as their client. The other half of the coin is the home buyers. These two clients of bank rate mortgage markets take opposing sides when it comes to investments. The investors want the highest possible return on their investments. On the other hand, the home buyers want the lowest possible interest rates on their bank rate mortgages. The result is a virtual tug-of-war.

As interest rates of bank rate mortgages decline, the interest of investors and home consumers alike are tweaked just a little bit. But this all depends on the direction of the economic growth, inflation, appetite for the given product, and several other factors. A typical outcome of lowering rates for bank rate mortgages though is lesser interest on the part of the investors. No investor would put down in his book a bank rate mortgage with a low interest rate.
