The interest rate on a one-year loan can be decomposed into a one-year risk-free (free from default risk) component and a risk premium that reflects the potential for default on the loan in that year. A change in economic conditions can affect the risk-free rate and the risk premium. The risk-free rate is normally affected by changing economic conditions to a greater degree than the risk premium. Explain how a weaker economy will likely affect the risk-free component, the risk premium, and the overall cost of a one-year loan obtained by (a) the Treasury, and (b) a corporation. Will the change in the cost of borrowing be more pronounced for the Treasury or for the corporation? Why?
