15.2 How households supply financial capital  (Page 89/43)

The ways in which firms would prefer to raise funds are only half the story of financial markets. The other half is what those households and individuals who supply funds desire, and how they perceive the available choices. The focus of our discussion now shifts from firms on the demand side of financial capital markets to households on the supply side of those markets. The mechanisms for saving available to households can be divided into several categories: deposits in bank accounts; bonds; stocks; money market mutual funds; stock and bond mutual funds; and housing and other tangible assets like owning gold. Each of these investments needs to be analyzed in terms of three factors: (1) the expected rate of return it will pay; (2) the risk that the return will be much lower or higher than expected; and (3) the liquidity    of the investment, which refers to how easily money or financial assets can be exchanged for a good or service. We will do this analysis as we discuss each of these investments in the sections below. First, however, we need to understand the difference between expected rate of return, risk, and actual rate of return.

Expected rate of return, risk, and actual rate of return

The expected rate of return    refers to how much a project or an investment is expected to return to the investor, either in future interest payments, capital gains, or increased profitability. It is usually the average return over a period of time, usually in years or even decades. Risk measures the uncertainty of that project’s profitability. There are several types of risk, including default risk and interest rate risk. Default risk, as its name suggests, is the risk that the borrower fails to pay back the bond. Interest rate risk is the danger that you might buy a long term bond at a 6% interest rate right before market rates suddenly raise, so had you waited, you could have gotten a similar bond that paid 9%. A high-risk investment is one for which a wide range of potential payoffs is reasonably probable. A low-risk investment will have actual returns that are fairly close to its expected rate of return year after year. A high-risk investment will have actual returns that are much higher than the expected rate of return in some months or years and much lower in other months or years. The actual rate of return    refers to the total rate of return, including capital gains and interest paid on an investment at the end of a period of time.

Bank accounts

An intermediary is one who stands between two other parties; for example, a person who arranges a blind date between two other people is one kind of intermediary. In financial capital markets, banks are an example of a financial intermediary    —that is, an institution that operates between a saver who deposits funds in a bank and a borrower who receives a loan from that bank. When a bank serves as a financial intermediary, unlike the situation with a couple on a blind date, the saver and the borrower never meet. In fact, it is not even possible to make direct connections between those who deposit funds in banks and those who borrow from banks, because all funds deposited end up in one big pool, which is then loaned out.
