The SARB’s New Inflation Regime and US Tariffs: What It Means for Long-Term Investment in South Africa

South Africa’s headline CPI rose to 3.5% year-on-year for the month of July, the highest level in ten months, though still within the longstanding 3–6% target range. This occurred as the South African Reserve Bank (SARB) continued signalling a shift toward a 3% inflation target, aiming to lower borrowing costs long-term. Simultaneously, the U.S. introduced a 30% tariff on South African exports, effective August 2025. This dual dynamic – tightening inflation policy and external trade pressure – creates a challenging environment for long-term investment. This blog explores how these developments intertwine and their implications for the investment climate.

A lower inflation target

In July 2025, the South African Reserve Bank (SARB) signalled that it would begin aiming for 3% inflation, effectively targeting the lower end of the official 3–6% band. At the time, this announcement raised questions about formal authority – under Section 224(1) and (2) of the Constitution, the primary object of the SARB is “to protect the value of the currency in the interest of balanced and sustainable economic growth,” and the law requires that SARB perform its functions independently but in regular consultation with the Minister responsible for national financial matters. National Treasury, acting for the Minister of Finance and Cabinet, is officially responsible for setting or approving the inflation target, in consultation with the SARB, while the SARB is tasked with monetary implementing policy to meet that target. The July communication therefore prompted debate about whether the Bank had moved ahead of government policy.

However, on 1 September the National Treasury and the SARB issued a joint media statement acknowledging the prospect of a formal change to the target band. Such coordination is critical for credibility: when the target is jointly owned, inflation expectations are more likely to remain anchored, reducing the risk premium that investors demand. This strengthened institutional alignment not only reinforces the SARB’s argument that a tighter 3% target could lock in recent gains in price stability, but also bolsters competitiveness by assuring markets that fiscal and monetary policy are working in tandem.

Alongside the institutional alignment on inflation targeting, the SARB cut the repo rate by 25 bps to 7.00%. Some expect further rate cuts under the new regime, projecting the repo rate could fall to roughly 5.75% by end-2025. In theory, a permanently lower inflation target translates into a lower nominal interest-rate path, because the “appropriate” real rate moves with inflation. At an inflation rate of 4.5%, McGregor (2025) indicates that stability requires a real rate of roughly 2.5%, implying a nominal repo rate of about 7% – close to today’s level. If inflation stabilises at 3%, the required real rate falls to around 2%, which points to a nominal repo rate closer to 5%. This 2-percentage-point gap highlights the potential for meaningfully cheaper borrowing, which could stimulate investment in housing, infrastructure, and other capital-intensive sectors.

Recent developments suggest these expectations are being reinforced, though with added caution. The SARB itself, in its July Monetary Policy Statement, indicated a forecast path implying several more cuts over the medium term, taking interest rates slightly below 6% eventually. Another key signal comes from a third quarter survey, conducted by the Bureau for Economic Research, showing that longer-term inflation expectations (over the next 5 years) have dropped to about 4.2%, down from earlier readings — this helps expand the space for lower rates, as inflation expectations are a major anchor for what lenders / investors demand in yields. Indeed, the bond market has responded positively to the announcement of a lower inflation target: yields on 10-year South African government bonds fell notably following the July decision, from 9.81% to 9.37%. This decline may reflect investor confidence that anchoring inflation at the lower bound will strengthen expectations and reduce risk premia.

That said, there are quite a few upside risks to inflation that could push it back toward– or above – the midpoint of the target band and thereby temper how aggressively the SARB can cut rates. Recent inflation data shows food, fuel, and utilities inflation ticking up, with the rise in headline inflation to 3.5% in July being driven largely by food and fuel price pressures. Utility and electricity costs also remain a concern – both administered prices and regulated tariffs are under pressure. The SARB’s own modelling suggests annualised inflation could creep up toward ~3.9% in the last quarter of 2025, reflecting these supply-side risks, as well as volatility in the exchange rate which can feed into imported inflation. Markets are therefore split: some economists expect the repo rate to be cut further in the near term, while others believe the SARB will hold off in September to assess whether these inflationary pressures solidify.

US tariffs on South African goods

On 8 August 2025, the U.S. reciprocal tariff of 30% on imports from South Africa came into effect. This duty was established under the framework of Executive Order 14257 (April 2025), which authorises reciprocal tariffs in response to large and persistent U.S. trade deficits. The U.S. modified those tariffs via a subsequent Executive Order on 31 July 2025, titled “Further Modifying the Reciprocal Tariff Rates,” which formally set the 30% rate for South Africa under the revised schedule. South Africa had been negotiating a bilateral trade agreement, making offers – including infrastructure investment in the U.S. – but ultimately failed to meet the deadline imposed by Washington. As a result, imports from South Africa into the U.S. are now subject to one of the highest reciprocal tariffs among sub-Saharan African exporters.

Although the tariff increase is broad, it most severely impacts South African goods that compete with U.S. products. Reports cite vulnerable sectors such as agriculture (e.g. fruit, wine), steel and aluminium, and automotive parts. For instance, a leading door-manufacturing firm warned its exports to the U.S. may become “no longer commercially viable” under a 30% tariff. Industry bodies like SACCI warn that tens of thousands of jobs could be lost in agro-processing and carmaking as a result [12] . South Africa’s exports to the U.S. accounted for roughly 7% of total exports in mid 2025, but certain sectors are much more exposed and will be hit hard.

Financial analysts are divided on how severe the macro impact will be. Some (including the SARB itself) judge the effect on overall growth and inflation will be modest. SARB Governor Kganyago noted that, because the U.S. is a relatively small market for SA, the 30% tariff is “a setback, but not catastrophic,” shaving only ~0.1 percentage-point off GDP growth. Likewise, JP Morgan reports that markets have largely priced in this shock and does not expect big swings in the rand or bond yields. When news broke on 12th August that South Africa was seeking to renegotiate the U.S. tariffs, the rand strengthened by over 1%, and local stocks rose – investors appeared hopeful that a deal might soften the blow. In contrast, trade bodies such as the South African Chamber of Commerce and Industry (SACCI) have warned that while the immediate market move is encouraging, the longer-term risks to investor confidence and bilateral trade relations remain substantial. Though the initial impact is muted, these developments underscore that the true economic cost may unfold over time, especially if trade sentiment sours or global external pressures intensify.

Interlinking effects on investment dynamics

A lower inflation target and US tariffs pull in different directions for investors. A firm 3% inflation anchor would reduce the inflation risk premium, supporting higher valuations of South African bonds and equities. Provided inflation remains subdued, lower interest rates can encourage capital-intensive investments and thus spur economic growth. On the other hand, large tariff movements inject uncertainty into trade-dependent industries. Exporters may delay expansion or seek new markets, and foreign investors could demand a higher risk premium. It is rather difficult to predict the extent to which stable inflation might partly offset trade worries by keeping finance conditions benign.

A credible low-inflation regime and balanced current account (as is the case in South Africa) tend to support a more stable rand, which is attractive to foreign investors concerned about currency risk. That said, trade tensions can cause capital flight from affected sectors, and heighten overall risk aversion. In the near term, the rand is likely to remain volatile: reactions to external shocks, policy announcements, and risk sentiment will still drive swings. However, if inflation remains low, growth expectations stay intact, and the government successfully negotiates lower tariff rates (or mitigates their effects via support measures), then the rand could gradually stabilise.

This combination of policies may also shift the mix of investments. Sectors less exposed to U.S. trade (or domestic-oriented sectors) could become relatively more attractive. For example, infrastructure projects or local services would benefit from lower funding costs (through reduced interest rates) and not necessarily be hindered by tariffs. Conversely, industries like steel, auto parts, or citrus (those heavily impact by tariffs) face headwinds, possibly delaying new projects.

With global interest rates now moderating, investors will look for growth and stability. The new 3% target signals that South Africa is committed to long-run price stability, which is positive. However, trade frictions and wider economic uncertainty raise questions about export-led growth. Long-term investment dynamics will depend on how the current “trade dispute” is resolved, how other countries and the global economy responds, and how South Africa adapts (e.g. diversifying trade, improving competitiveness etc.). If inflation remains subdued, and the cost of capital stays low, the actions of the SARB could potentially serve to partially offset slower export growth.

Conclusion

If the National Treasury and SARB succeed in anchoring inflation at 3%, it will likely lower financing costs and boost confidence in South African markets. However, US tariffs and related economic policies introduce a significant external risk, especially for exporters, that could dampen investment in certain sectors. The interplay is complex: low inflation targets help soften the blow of higher trade costs, but unresolved global tensions could still slow growth and deter some foreign investment. In times like this, the domestic policy response may prove critical in shaping long-term outcomes.
