What interest rates usually effect in your life are primarily the things that you buy on credit like a house, car, and stocks and bonds. For example, if you go to buy a house the interest rate is going to determine 'how much house' you can buy.
When interest rates are high you buy less house because the payments would be prohibitive to buying a bigger house. When the interest rates are low, you get more house for your money, due to the lower payments.
Interest Rate Effects- An Overview
The definition of an interest rate is the cost of borrowing money from a lender, applied on an outstanding balance, paid at regular intervals and expressed as a percentage of fixed or variable rate of the total amount of credit owed.
There are two types of interest rates: real and nominal. The expected increase in real income, relative to the amount owed, is the real interest rate. In order to take inflation into account the actual rate charged, which is the nominal interest rate, is adjusted through a formula.
The point of fluctuating interest rates is to affect peoples' and firms' demand for goods and services. Interest rates react to fundamental factors of supply and demand as well.
For example, the price of interest rate futures are affected by the supply and demand for credit. The credit offered is in turn, affected by the economic forces of the Federal Reserve Board monetary policy, legislative and executive fiscal policies, and business activity. Interest rates are directly or indirectly responsible for much of what drives the financial market, probably more than any other factor, and as such, it is important to anyone involved in finance to stay aware of the interest that affects them.
