Using Interest Rates to Make Investment Decisions
Interest rates are essentially the price of money. As such they are amazingly important when making investment decisions. If you want to buy stocks, bonds, a house, or even a car you should first look at where interest rates are at.
There are several different rates but only a few that the average person has to follow. Go to any finance web site and you can find a chart of the 90-Day Treasury Bills as well as a chart of either the 10-Year or 30-Year Treasury. This way you can see the trend of long term and short term interest rate. While the rate that you will get at your bank will be a bit different, usually higher, the trend will be the same. If interest rates have been headed lower then you might want to wait a while before going out and getting a loan as it will likely get cheaper to borrow in a few months.
By the same token if rates are going up then you will either want to postpone your purchase for several months and maybe a few years when possible, and if not possible then you will want to buy right now before rates go even higher. Most investors and consumers never look at this but the results can be huge over the course of a lifetime. If you live to the age of 80 and you buy 3 homes over that time you could easily save hundreds of thousands of dollars over your life. If you apply it to even the purchase of a car you can save even more.
If you are an investor then you should already be tracking interest rates. This does not have to be complicated. You can be a global macro trader or just a regular stock investor and the basic principles still apply. An easing or loose central bank is typically good for investments and a tight one is bad.
While the short and long term rates is all you need to follow it is also good to follow rates like the AAA and BAA corporate ratesas well as the Merrill Lynch Interest Rate proxy which shows the average interest rate for consumers. Interest rates are the price of money, all else follows.
