Question

In recent years, by how much does the RBA usually adjust the cash rate when it makes an adjustment?

BlackTom AI · Accepted Answer

RBA typically moves the cash rate in increments of 25 basis points, i.e. 0.25%.

1) Relevant knowledge points and concepts
- The “cash rate” is the policy interest rate set by the Reserve Bank of Australia (RBA).  
- Central banks commonly adjust rates in basis points; 1 basis point (bp) = 0.01 percentage point.  
- A 25 bp change equals 0.25 percentage points, and this size is the customary, incremental step used by the RBA in ordinary decisions.

2) Step‑by‑step reasoning
- Identify the usual step size: central banks prefer manageable, signal‑clear increments; for the RBA that customary increment is 25 bp.  
- Convert the candidate answers into basis points to compare:  
  a. 0.25% = 0.25 percentage points = 25 bp  
  b. 0.5% = 0.50 percentage points = 50 bp  
  c. 0.01% = 0.01 percentage points = 1 bp  
  d. 1% = 1.00 percentage points = 100 bp

3) Calculations / intermediate steps
- 0.25% × 100 = 25 basis points (since 1% = 100 bp).  
- By the same conversion: 0.5% = 50 bp, 0.01% = 1 bp, 1% = 100 bp.

4) Why the correct answer is correct
- The RBA’s routine adjustments have historically been in 25 bp increments because this size balances responsiveness to economic conditions with the desire to avoid overreacting; hence when the RBA “usually adjusts” the cash rate it does so by 0.25%.

5) Why other options are incorrect (brief)
- b. 0.5% (50 bp) is larger and used less commonly; it is not the usual step.  
- c. 0.01% (1 bp) is far too small for a typical policy move and is not used as the standard adjustment.  
- d. 1% (100 bp) is a very large move reserved for exceptional circumstances and is not the usual adjustment.

6) Conclusion / final confirmation
Therefore the correct choice is a. 0.25%, which matches the provided answer.
