The South African Reserve Bank's Monetary Policy Committee is the single most important domestic driver of ZAR direction. Understanding how SARB decisions are made, what they signal, and how markets respond is essential for any trader holding ZAR-denominated positions.
What the SARB MPC Does
The Monetary Policy Committee sets the repo rate — the rate at which the SARB lends money to commercial banks overnight. Banks use this as their floor cost of funding, which flows through to the prime lending rate (currently repo + 3.5%) and ultimately to mortgage rates, personal loans and business credit.
The MPC meets six times per year, announcing decisions on Thursdays at 15:00 SAST. The 2026 schedule remaining dates: 23 July, 23 September, 19 November. Decisions are announced via a statement from the Governor, followed by a press conference.
As of May 28, 2026, the repo rate stands at 7.00% — raised 25 basis points at the May meeting, reversing a 2025 easing cycle that had brought rates down from 7.75% to 6.75% over three consecutive cuts. The hike was driven by external inflation pressures: escalating energy prices, El Niño drought risk and a weaker rand feeding import costs.
How Rate Decisions Affect the Rand
The relationship between interest rates and currency value flows through capital flows. Higher South African rates relative to major economies attract foreign capital seeking yield — investors buy rand-denominated government bonds, which requires purchasing ZAR, strengthening the currency. Lower rates do the opposite.
In practice, the rand's response also depends on the surprise factor:
- As expected: muted reaction; rate decision was priced in
- Hawkish surprise (unexpected hike or stronger-than-expected statement): ZAR strengthens, USD/ZAR falls
- Dovish surprise (unexpected cut or weaker statement): ZAR weakens, USD/ZAR rises
The Governor's statement and tone often move markets as much as the rate decision itself. Signals about the future direction of policy — what the MPC is watching and what would change their view — influence positioning for the next meeting.
The Rand as an Emerging-Market Currency
The ZAR is classified as an emerging-market currency, which means it behaves differently from major currencies (USD, EUR, GBP). Two forces dominate rand movement beyond domestic policy:
Global risk appetite. When global investors move into risk assets, they tend to buy higher-yielding currencies including ZAR (carry trade flows). When risk aversion rises — geopolitical events, global recessions, financial market stress — capital flows out of emerging markets and into safe-haven currencies (USD, JPY, CHF), weakening the rand sharply.
Commodity prices. South Africa is a major exporter of gold, platinum group metals and coal. Rising commodity prices improve the trade balance and attract foreign exchange inflows, supporting the rand. Falling commodity prices do the opposite.
This means USD/ZAR can move significantly even when the SARB makes no policy change — driven by events in Washington, Beijing or commodity markets that have nothing to do with South African fundamentals.
ZAR Pair Characteristics
| Pair | Typical daily range | Key session | Main driver |
|---|---|---|---|
| USD/ZAR | 200–400 pips | London + NY overlap | USD strength, SA risk sentiment |
| EUR/ZAR | 250–450 pips | London session | EUR/USD cross + ZAR |
| GBP/ZAR | 300–500 pips | London session | GBP/USD cross + ZAR |
ZAR pairs are classified as exotic pairs — they carry wider spreads than major pairs, particularly outside London and New York trading hours. During the Asian session (00:00–09:00 SAST), liquidity is thin and spreads on ZAR pairs can be two to five times wider than during peak hours.
How to Prepare for SARB MPC Days
Ahead of the meeting:
- Note the current repo rate and any SARB communications since the last meeting
- Check economist consensus from local banks (Absa, Nedbank, Standard Bank often publish pre-MPC notes)
- Review your open ZAR positions — any that will be significantly affected by a surprise?
On the day:
- Treat a SARB MPC decision day like NFP: reduce position sizes on open ZAR trades before 14:00 SAST
- Widen stop-losses to accommodate an initial sharp move
- Wait for the Governor's statement to be published in full before drawing conclusions from the initial price reaction
Finding the schedule:
