Market participants have substantially reduced their expectations for additional interest rate hikes by the South African Reserve Bank (SARB) following a landmark United States and Iran peace agreement reached over the weekend, which sent global oil prices sharply lower and has raised the prospect of easing inflationary pressures across emerging markets, including South Africa.
Key Takeaways
- The peace deal is doing the heavy lifting: The US-Iran peace agreement has been the primary catalyst for the shift in rate expectations, with oil price declines easing inflation fears and prompting traders to halve their bets on near-term SARB tightening.
- One hike remains on the table, not two: Markets have repriced from 70 basis points of cumulative tightening to just 32 basis points for the full year, implying a single quarter-point increase by November rather than the two hikes previously anticipated.
- The doves now have more ammunition: With five-year breakeven inflation falling 16 basis points following the peace deal, the two MPC members who voted against the May hike are better positioned to resist further tightening at the July meeting.
What Forward-Rate Agreements Are Now Pricing In
Forward-rate agreements, which are financial contracts used by traders to speculate on or hedge against future interest rate movements, are now pricing in approximately 15 basis points of monetary tightening at the SARB’s upcoming policy meeting on 23 July. This represents a notable retreat from the 30 basis points of tightening that had been priced into those same contracts just one week prior.
A basis point is one-hundredth of a percentage point (0.01%). Financial markets use basis points to avoid ambiguity when discussing small interest rate movements.
Looking further ahead across the full year, the contracts are now indicating a cumulative total of 32 basis points of rate hikes for 2026, a significant reduction from the 70 basis points that had been anticipated as recently as a week ago.
The current market positioning implies that traders expect just a single full quarter-point increase to materialise before the SARB’s November rates meeting, which would be a considerably more restrained tightening cycle than had previously been anticipated.
| Metric | One Week Ago | Current |
|---|---|---|
| July meeting pricing | 30 bps | 15 bps |
| Full-year hike expectations | 70 bps | 32 bps |
| Implied full hikes by November | ~2 | ~1 |
Forward-rate agreements (FRAs) are one of the key tools investors use to gauge market consensus on future central bank decisions. They are not guarantees of what will happen, but they reflect the probability-weighted expectations of sophisticated market participants.
A Meaningful, Though Incomplete, Reversal of Expectations
Whilst this repricing does not represent a wholesale abandonment of the case for further monetary tightening, given that at least one additional rate hike is still anticipated by traders, it does mark a meaningful downward revision in both the scale and the timing of expected policy action. The previous consensus had centred on 50 basis points of additional tightening, with a potential move as early as July. The new market view pushes the most likely timing of any hike further back and reduces the anticipated magnitude of the tightening cycle.
The SARB’s Recent Rate Decision
The South African Reserve Bank raised borrowing costs by 25 basis points at its meeting last month, lifting the benchmark interest rate to 7 per cent and delivering the central bank’s first rate increase in three years. The decision was driven by intensifying inflationary pressures that policymakers attributed in large part to the conflict in Iran, which had been pushing energy and food costs higher.
South Africa’s repo rate had been at 8.25% as recently as 2023 before the SARB began a cutting cycle. The May 2026 hike to 7% reversed part of that easing cycle, reflecting the re-emergence of inflationary risks.
At that meeting, policymakers also signalled that further monetary tightening could be warranted should the conflict in the Middle East continue to drag on, creating additional headwinds for the domestic economy.

Inflation Outlook and Market-Based Measures
Inflation in South Africa, which is Africa’s largest economy by output, is expected to have risen to 4.7 per cent in May, up from 4.0 per cent recorded in April, based on the median forecast of 18 economists polled in a Bloomberg survey. Some analysts hold a more cautious view, with certain forecasters expecting the figure to climb as high as 5.1 per cent.
South Africa’s SARB targets inflation within a band of 3% to 6%, with the midpoint at 4.5% considered the sweet spot. When inflation moves towards or above the upper end of that band, the MPC typically faces pressure to tighten monetary policy.
The central bank officially targets inflation at 3 per cent, meaning even the median estimate of 4.7 per cent leaves the expected reading well above the preferred target level.
How the Peace Deal Shifted Market Inflation Expectations
Following the weekend peace agreement between the United States and Iran, however, investor expectations of average inflation over the next five years, as measured by breakeven rates derived from inflation-linked bonds, fell by 16 basis points to 4.23 per cent, signalling increased market confidence that price pressures may ease in the months ahead.
What This Means for the MPC’s Dovish and Hawkish Camps
The easing of market-based inflation expectations is likely to provide meaningful support to the more cautious, growth-oriented members of the SARB’s Monetary Policy Committee (MPC), who had been outvoted when the committee convened in May. At that meeting, four of the six MPC members voted in favour of raising interest rates, whilst the remaining two members called for borrowing costs to be held steady.
Governor Kganyago’s Broader Inflation Concerns
SARB Governor Lesetja Kganyago, speaking after the May decision, noted that the war in Iran was not the sole driver of inflationary risk in the domestic economy, and he specifically highlighted weather-related conditions as an additional and significant concern warranting ongoing vigilance.
Governor Kganyago has served as SARB Governor since 2014 and is widely regarded as one of the most credible central bank governors on the African continent. His hawkish credentials have helped anchor South Africa’s inflation expectations during periods of currency weakness and external shocks.
The SARB’s Three Scenarios for Future Policy
In recognition of the heightened degree of uncertainty surrounding the outlook, the SARB presented three alternative economic scenarios at its May meeting to help contextualise its thinking on the potential future path for interest rates.
- Scenario 1: Prolonged Middle East conflict involving a sustained escalation in hostilities, which would drive higher food and oil prices globally and contribute to a weaker rand, placing additional upward pressure on domestic inflation. With the peace deal now potentially resolving or at least de-escalating the conflict, the risk associated with this scenario may be considerably reduced.
- Scenario 2: El Niño weather pattern, which historically brings drought conditions to southern Africa. The South African Weather Service has already raised warnings about current drought patterns affecting the country, noting that whilst the onset has been gradual, the destructive impact on agriculture and water resources remains a serious concern.
- Scenario 3: Non-linear or shock effects, which the SARB used to model the impact of large, unexpected developments that fall outside the base case or other identified risk scenarios. These could include sudden financial market disruptions, geopolitical surprises, or abrupt shifts in global commodity prices.
Central banks increasingly use scenario analysis, rather than single point-in-time forecasts, to communicate the range of policy responses that may be appropriate under different conditions. This approach improves transparency and helps markets understand the conditionality of policy guidance.
Notably, all three of the scenarios presented by the SARB implied a combination of higher inflation and weaker economic growth relative to the base case, and all three scenarios pointed towards some degree of additional monetary policy tightening as the appropriate policy response under those conditions.
Conclusion
The US-Iran peace agreement has arrived at a pivotal moment for South African monetary policy, offering the SARB’s rate-setting committee a credible basis for adopting a more measured approach to further tightening. Whilst the inflation outlook remains elevated and weather-related risks continue to cloud the domestic picture, the sharp repricing in oil markets and the accompanying decline in long-run inflation expectations have meaningfully shifted the calculus ahead of the July meeting. Markets are no longer bracing for an aggressive tightening cycle, and the dovish minority on the MPC now has tangible evidence to support a pause. Much will depend on how durably the peace holds and whether El Niño-driven drought conditions intensify over the coming months, but for now, South Africa’s rate trajectory appears considerably less steep than it did just one week ago.
