If you invest your money, you will have to deal with numerous risks. For instance, if you buy a bond, you run the risk of the borrower defaulting or being repaid with debased money. As a stock investor, you face the risk that the company’s business model will not live up to expectations, or that it, at the extreme, will go bankrupt. In an unhampered financial market, prices are formed for these and other risk factors.
For instance, a bond with a high default risk will typically carry a high yield. The same goes for debt denominated in an unsound currency. Stocks of companies that are deemed risky tend to trade at a lower valuation level than those considered low risk. All these risk premiums, if determined in the unhampered market, constitute a portion of an asset’s price, be it a bond or a share. They play a vital role in the way capital is allocated in an economy.
Risk premiums are meant to compensate investors for the risk of losses resulting from adverse developments. If you buy a stock at a depressed price relative to the firm’s earnings power, it tends to reduce your downside (while offering the chance of great gains). At the same time, risk premiums increase investors’ cost of capital. This, in turn, discourages them from engaging in overly risky investments.
Decline in risk premiums:
In other words, risk premiums determined in an unhampered market align the interests of savers and investors. Of course, one cannot be sure that ex ante risk premiums are always correct. Sometimes it turns out that risks were overestimated, sometimes they were underestimated. However, the unhampered market is still the best and most efficient means to determine the price of risk.
