Nominal v. Real Interest Rates: Topic Checklist (Macroeconomics 4.2)

Specific “I can…” statements for nominal and real interest rates and expected inflation, each linked to the guide section and practice question that tests it.

Work through the list without notes. If you cannot do a statement, follow its link, then come back. Guide = study guide; Practice = practice questions.

Understanding

  • I can define the nominal interest rate and the real interest rate, and say which one measures purchasing power. (Guide: “What an interest rate measures”; Practice Q1, Q6(a))
  • I can explain why lenders and borrowers build expected inflation into the nominal rate. (Guide: “How lenders and borrowers set a nominal rate”)
  • I can explain the difference between the real rate expected when a loan is agreed and the real rate calculated in hindsight. (Guide: “Calculating a real rate in hindsight”; Worked example 2(d))

Calculation

  • I can calculate a nominal rate from an expected real rate and expected inflation. (Guide: Worked example 1(a); Practice Q2, Q6(b))
  • I can calculate a real rate in hindsight from a nominal rate and actual inflation, including a negative real rate. (Guide: Worked example 1(b); Practice Q3, Q6(c))
  • I can calculate inflation from CPI data and then the real interest rate for each year, including years with deflation. (Guide: Worked example 2; Practice Q5)
  • I can find the new nominal rate when expected inflation changes and the expected real rate stays the same. (Practice Q4, Q7(d))

Reasoning

  • I can explain who gains and who loses when actual inflation is higher or lower than expected. (Guide: Worked example 1; Practice Q6(d))
  • I can explain why a higher nominal rate is not always a better deal for a saver. (Guide: Worked example 2(c); Practice Q7(b))
  • I can explain why deflation makes the real rate higher than the nominal rate. (Guide: Worked example 2, “Check”)
