Major purchases such as cars and homes can be difficult to make without getting a loan, unless you've saved up cash for years. Whenever you buy something with a loan or credit -- whether it's a large purchase or a small one -- you have to pay interest on the debt until you pay it off. The interest rates that lenders charge can have a significant influence on the level of consumer demand in the economy and on economic growth.
Interest Rates and Demand
Customer or consumer demand refers to the total amount of stuff that people want to buy. Low interest rates make it cheaper to borrow money, which in turn makes it less expensive to buy anything from an education to electronics. As a result, consumer demand tends to increase as interest rates fall. If interest rates are high, borrowing is costly, which is likely to reduce demand and total consumption.
Interest Rates and Investment
If you have extra cash lying around, saving or investing it can bring a return over time. Interest rates are an important consideration when deciding whether to save cash in a bank account that pays interest or to put it into investments that might appreciate but don't pay interest, such as stocks. In general, low interest rates encourage investment because they make saving less rewarding, while high interest rates tend to discourage investment. Low interest rates also make it cheaper for businesses to take out loans and invest in new projects.
Consumer demand and investments are key factors in determining the economy's overall health and growth rate. High levels of demand and consumption tend to increase companies' profits, allowing them to hire more workers and pay them more. Therefore, low interest rates can help spur economic growth and reduce unemployment, while high interest rates can slow growth.
The importance of interest rates on consumer demand and the economy in general is a key concern for government economists. The U.S. Federal Reserve Board influences interest rates by altering the federal funds rate, which is the interest rates banks charge one another for short-term loans. When the economy is not doing well, the government can reduce the federal funds rate in an attempt to spark consumer spending, investment and growth. This tends to reduce interest rates in the economy as a whole.
