INTEREST RATE
Nominal interest rate = price of money over time = Additional sum of money the borrower agrees to pay, on top of the loaned amount, to the original lender or to the current owner of the loan.
Nominal interest rate = Real interest rate + Expected inflation + Credit risk premium + Liquidity premium + Other risk premiums Real interest rate (ex ante) = Nominal interest rate – Expected inflation
Real interest rate (ex post) = Nominal interest rate – Actual inflation
If current inflation exceeds (falls short) of expected inflation, the ex post real interest rate is higher than the ex ante real interest rate.
