QUESTION 68 (5 marks)
The nominal cash rate falls from 5% to 4.5%, while expected inflation falls from 4% to 2%. Using the exact real-rate ratio, calculate the real cash-rate proxy in both periods. Assess the statement that the nominal cut alone proves monetary conditions became easier.
Practice marking scheme
Answer
Real-rate proxy rises from approximately 0.96% to 2.45%; the nominal cut is insufficient evidence.
Working
First: 1.05/1.04 − 1 = 0.9615%. Second: 1.045/1.02 − 1 = 2.4510%. Lower expected inflation more than offsets the nominal cut in this measure. Overall stance also depends on the neutral rate, lending spreads and financial conditions. Without those observations, the nominal change alone cannot establish the degree of stimulus.
Marking criteria
- Calculates both real-rate proxies. [2 marks]
