With the South African Reserve Bank (SARB) meeting on 31 July 2025 to decide whether to cut the repo rate from its current 7.25%, and fresh inflation data due on 23 July (the last print came in at 2.8% year-on-year), we took a moment to pause… pivot… and rethink what a shift in SARB’s inflation stance could mean for local rates and the rand.
What if South Africa’s Inflation target were revised to 3.00%?
If SARB were to move from its current 3–6% inflation target band to a flat 3% target, it would mark a significant shift in monetary policy, one with far-reaching implications.
Such a move would signal a more hawkish approach to inflation, potentially reshaping investor expectations, capital flows, and the cost of borrowing across the economy.
Hence, we decided to open the economics textbook, cut through the complexity, and analyze what could happen to SA markets if the inflation target was now 3%... well, let’s break it down slowly and systematically:
1. Interest Rates Could Likely Rise (Medium term outlook)
Short-Term View: No Immediate Hike/Cut after change to 3%
- Headline CPI Inflation is currently at 2.8%, with the last three prints at 2.8%, 2.7%, and 3.2%.
- With inflation already at or below the proposed 3% target, no immediate rate hike/cut would be necessary after changing the target to 3%.
Medium-Term Pressures: Rates May Stay Higher for Longer
- Yes, higher for longer!
- Initial thoughts would be that rates go down, but let’s think about it. SA Inflation forecasts suggest a return to the 4–5% range as shown below:
- Thus, if inflation expectations remain above 4%, SARB would need to maintain or even raise rates to anchor inflation closer to 3%.
- This would mirror post-COVID dynamics, where central banks had to act decisively to rein in inflation. Remember that rampant Covid Inflation.
2. Impact on the Rand (ZAR): Good strategy as ZAR is likely to Strengthen — All Else Equal
- A shift to a stricter 3% inflation target would likely enhance the SARB’s policy credibility and help anchor long-term inflation expectations.
- If markets are convinced of the central bank’s commitment, the rand could benefit in several ways:
- Increased investor confidence in South Africa’s macroeconomic framework.
- Attraction of foreign capital, drawn by higher real interest rates. Important as the US and EU are projected to have a deeper rate-cutting cycle than SA. Hence, raise money cheaply in the US/EU at lower rates and invest in SA for Yield from higher SA rates=increased demand of ZAR=currency strength (Ah... We see your thinking, governor).
- Thus, there is potential for rand appreciation or greater stability in the ZAR over the medium term.
- However, short-term volatility could rise. Particularly if markets question SARB’s ability to meet the new target or perceive a lack of political backing. The credibility of the shift and the consistency of its implementation will be key to the rand’s trajectory.
3. Implications for the Economy
- A shift to a lower inflation target would likely require tighter monetary policy, which could have both short-term costs and long-term benefits:
Potential Short-Term Effects for SA Economy
- Slower GDP growth, as higher interest rates dampen consumption and investment.
- The SARB has stressed that U.S. President Donald Trump's trade war and elevated uncertainty were likely to weaken the world economy.
- The SARB lowered its 2025 economic growth forecast to 1.2% from 1.7%.
Rising unemployment, particularly if inflation is driven by cost-push factors like fuel or food.
Pressure on household budgets, especially in lower-income segments.
Potential Long-Term Gains for SA Economy
- Improved price stability, reducing uncertainty for businesses and consumers.
- Stronger investment and savings culture, supported by predictable inflation.
- Enhanced purchasing power, especially for the poor, as inflation erodes real incomes less over time.
4. Case Study using our Emerging Market (EM) Competitor Mexico: Tight Policy, Strong Peso
- Inflation Target: Still a band of 2% to 4%, but the Mexican Central Bank (Banxico) is more focused on hitting the 3% midpoint (i.e. lower target vs upper band of 4%), signaling a hawkish stance.
- Interest Rates: Held high at 11.25% (mid-2025), with only gradual rate cuts expected to preserve credibility.
- Currency (MXN): Mexican Pesso is one of the strongest EM currencies, supported by:
- High real interest rates
- A disciplined central bank
- Bottom line: Mexico’s firm policy mix and structural tailwinds have made it a standout among emerging markets.
Thus, we see what the SARB is trying to achieve in the short-to-medium term: (1) protecting the currency by trying to keep the rand strong, (2) attract foreign investment as our real rates would be higher vs. the developed markets with deeper rate cuts done /planned.
I leave you with this food for thought…
