There is not single interest rate anyways. There are long term and short term rates. Shorter term rates may tend to follow rates set by the Fed (rates at which the banks can borrow from the Fed) and longer term rates tend to be based on Treasury note rates. Mortgages mostly follow ten year Treasury rates. Interest rates on Treasury notes are based on auctions and are set by supply and demand for the notes.
There are three basic components of an interest rate and expected rate of inflation is probably the biggest factor. If a lender expects a high rate of inflation during the time of the loan, they will demand a high interest rate to compensate them for this- giving them a real rate of return. The second component is their desired real rate of return and the third is a risk premium- the more likely a person is to pay back the loan, the lower the risk premium that gets added to the base rate. So let's try an example. Say the expected rate of inflation during the loan period is three percent. A lender will then start with three percent as the base for their rate. They want a half a percent real return on the loan so that gets added in. Now the rate is up to 3.5%. Say the borrow has a good credit history and is considered very reliable- now we add in one tenth of a percent so the final rate will be 3.6%.
Thus, there is not any single interest rate to set. Rates will vary depending on many factors- the length of the loan, the expected rate of inflation, a risk factor for the borrower, and the desired real rate of return the lender wants.
Correct, but he is talking about the Fed its pretty obvious that he is refering to the rates the Fed sets.
