The real interest rate is the rate of interest an investor expects to receive after allowing for inflation, reflecting the true cost of borrowing and the true yield on savings. It is a critical measure for economic decision-making as it influences consumption, investment, and the allocation of resources in an economy.
Interest rate risk refers to the potential for investment losses due to fluctuations in interest rates, which can affect the value of fixed-income securities like bonds. It is a critical consideration for investors and financial institutions as changes in interest rates can impact borrowing costs, investment returns, and overall economic conditions.
