The Rand, oil, interest rates and one unexpected decision

There is an old rule in currency markets that when everyone is looking in one direction, it often pays to glance the other way.

That felt particularly true in July.

Going into the second half of the month, most market participants seemed convinced that the South African Reserve Bank (SARB) would raise interest rates again. Inflation had accelerated, fuel prices were pushing higher, and policymakers had spent much of the year emphasising the importance of keeping inflation expectations anchored.

Then the SARB did something markets do not particularly enjoy.

It surprised them.

The decision to leave rates unchanged may end up being remembered as the defining moment for the Rand in July. But to understand why the currency reacted the way it did, we need to step back and look at the bigger picture.

Because July was never really only about South Africa.

It was about oil.

It was about the US.

It was about the Middle East.

And, increasingly, it was about trade.

And as is so often the case, it was ultimately about confidence.

A month where the Rand largely held its ground

Despite the volatility, the Rand's overall performance during July was actually more resilient than many might have expected.

USD/ZAR spent much of the month trading in the mid-R16s, ending July around the R16.50 to R16.60 region. While the Rand weakened slightly over the course of the month, the move was relatively modest considering the number of risks investors had to navigate.

That resilience tells us something important.

International investors have not abandoned South Africa.

In fact, many continue to view the Rand as one of the more attractive emerging market currencies when global conditions are stable. South Africa still offers relatively high interest rates, deep financial markets and significant exposure to commodities.

The problem is that the Rand seldom trades purely on South African fundamentals.

When investors are willing to take risk, the Rand benefits.

When they become nervous, the Rand is often among the first currencies to feel it.

That dynamic was on full display throughout July.

Oil became one of the most important stories

One of the more interesting features of July was how often currency traders found themselves paying attention to energy markets.

The conflict in the Middle East remained a major focus for global investors. Every development had implications for oil prices, shipping routes and inflation expectations. At various points, fears of supply disruptions helped push energy prices higher, creating concern for central banks around the world.

For South Africa, higher oil prices are never particularly welcome news.

We are a net importer of oil. Higher fuel costs eventually work their way through transport, logistics and consumer prices. That then feeds into inflation, which brings the Reserve Bank into the conversation.

By July, those concerns were already visible in the inflation data.

Headline CPI rose to 5.0%, the highest reading in two years and above market expectations. Much of that pressure came from transport costs, heavily influenced by developments in global energy markets.

This created a chain reaction.

Higher oil prices contributed to higher inflation.

Higher inflation increased expectations of a SARB rate hike.

The market positioned accordingly.

Then the SARB surprised everyone.

The decision that changed the month

Markets are funny things.

Often, it is not the actual decision that matters most.

It is the difference between what happened and what people expected.

Many economists entered July expecting the SARB to increase rates by 25 basis points. The inflation backdrop seemed to justify it, and market pricing had increasingly shifted in that direction.

Instead, policymakers left rates unchanged at 7.00%.

The message was essentially that policy was already restrictive enough and that inflation should gradually move back towards target over time.

The market's response was immediate.

The Rand weakened sharply and briefly lost more than 2% against the US Dollar

Why?

Because currencies trade on future expectations. Investors holding Rand assets partly do so because of the yield advantage South Africa offers. If they expect rates to rise and that increase does not materialise, some of that support disappears.

The irony is that the SARB was not necessarily saying inflation was no longer a concern.

It was simply saying that the current level of interest rates may already be sufficient.

Markets had expected a stronger warning.

Instead, they received patience.

The Rand did not particularly like that.

America remains the Rand's biggest external influence

If July showed us anything, it is that no discussion about the Rand is complete without discussing the Dollar.

The Federal Reserve also held interest rates steady during July. However, unlike previous meetings, there were clear divisions inside the committee, with several policymakers wanting higher rates.

That matters because every conversation about US interest rates is ultimately a conversation about the strength of the Dollar.

When US rates rise, investors can earn attractive yields in Dollar assets with relatively little risk. Emerging markets then need to work harder to compete for investment flows.

The good news for the Rand was that the Dollar spent much of July on the back foot. The softer Dollar backdrop helped offset some of the negative impact from the SARB surprise.

Had the Dollar been strengthening aggressively at the same time the SARB disappointed markets, the Rand's losses could have been considerably larger.

Instead, global conditions provided a buffer.

It was not enough to spark a major rally, but it prevented something worse.

July also brought another complication from Washington.

The Trump administration announced a fresh round of tariffs affecting roughly 60 trading partners around the world, with South Africa included among the countries subject to a new 12.5% tariff on affected exports to the US. The announcement formed part of a broader protectionist trade agenda and immediately raised questions about future trade relationships and export competitiveness.

On their own, tariffs do not necessarily cause a currency to weaken overnight.

Markets are usually more concerned about what tariffs represent than the tariffs themselves.

In this case, they served as a reminder that global trade tensions remain alive and well. Investors generally prefer certainty, particularly when allocating capital to emerging markets. When a major economy begins erecting new trade barriers, it inevitably introduces a degree of uncertainty into future growth expectations.

For the Rand, which tends to perform best when investors are comfortable taking risk, the announcement became another reason for caution. South Africa's economy remains reliant on foreign capital flows, commodity exports and access to international markets. Anything that raises questions about those relationships can weigh on sentiment, even if the direct economic impact takes time to materialise.

The tariffs were not the primary driver of Rand weakness during July. The SARB surprise and shifting global interest rate expectations played a bigger role.

But they certainly did not help.

Combined with concerns around inflation, oil prices and global growth, the tariff announcement became another small headwind in a month where the Rand was already navigating a complex environment.

Sterling stayed strong

The Pound was not the main story of July, but it remained an important one for anyone moving money between South Africa and the UK.

GBP/ZAR held comfortably above the R22.00 level for most of the month and finished near R22.20

Part of the explanation lies with the Bank of England.

Like the Federal Reserve, the Bank of England kept rates unchanged. However, policymakers continued to express concern about inflation risks, particularly those linked to energy prices. Several members even voted in favour of a rate increase.

The message was subtle but important.

The Bank of England remains cautious.

The SARB became slightly more patient.

Those differences matter in foreign exchange markets.

As a result, sterling continued to find support against the Rand despite not experiencing a particularly dramatic month against the Dollar itself.

For South African importers, property buyers and investors with UK exposure, this meant that GBP/ZAR remained stubbornly elevated throughout much of the month.

So where does this leave the Rand?

If there was a theme running through July, it was uncertainty.

Investors spent much of the month trying to answer four difficult questions simultaneously.

Will inflation continue to rise?

Will central banks have to tighten further?

Will geopolitical tensions push oil prices higher?

And will a renewed wave of trade protectionism slow global growth and international trade?

Right now, nobody has a definitive answer.

What we do know is that the Rand remains highly sensitive to all four.

The currency is not weak because South Africa is in crisis.

Nor is it especially strong because all our domestic challenges have disappeared.

Instead, the Rand sits at the intersection of local policy decisions and global market sentiment.

That makes it both fascinating and frustrating.

As we move into August, the path of least resistance still appears to be a broadly range-bound Rand, with global developments likely to matter just as much as domestic ones. A softer Dollar, easing inflation pressures and calmer geopolitical conditions could support further Rand strength. Conversely, another oil shock, escalating trade tensions or more hawkish central banks abroad could quickly reverse that momentum.

For now, the story of July is not that the Rand collapsed.

It did not.

The story is that a currency often accused of being fragile absorbed a surprising amount of bad news. A surprise interest rate decision. Elevated inflation. Middle East tensions. Higher oil prices. New US tariffs.

And yet, it was still standing at the end of the month.

Sometimes, in foreign exchange markets, that is a stronger result than it first appears.
