Published on Friday, 31 July 2026, the analysis warned of possible pressure on the rand during August and noted that August has historically been the currency’s weakest month. Bloomberg data going back to 1997 shows the rand has recorded an average loss of more than 2% against the US dollar during August.
The seasonal weakness is partly linked to reduced market activity during the European summer holidays, when traders traditionally cut risk and take profits on carry-trade positions. The rand is particularly exposed because it is widely used as a higher-yielding emerging-market currency in carry trades, according to Bloomberg’s analysis.
This week, however, investors have a more immediate domestic trigger to consider: South Africa’s July Consumer Price Index (CPI), due on Wednesday.
The inflation reading could prove important for the rand, with investors watching for clues about the direction of South Africa’s interest-rate cycle. A softer-than-expected reading could strengthen expectations for monetary easing and potentially weigh on the currency, while a higher reading could reinforce expectations that interest rates will remain elevated, potentially supporting the rand.
The rand was trading at around R16.17 against the dollar, R18.73 against the euro and R21.90 against the pound on Monday according to Andre Cilliers, currency strategist at TreasuryONE.
“The Rand continues to trade at the lower end of its recent range, holding on to most of last week’s gains against all the majors,” Cilliers said, as traders await Wednesday’s local inflation numbers.
Cilliers said international developments were also supporting the currency. The weaker US dollar and reduced expectations of a Federal Reserve rate hike were helping to underpin the rand. Weaker-than-expected US economic data has reduced expectations of a September rate hike, putting additional pressure on the dollar.
SA monetary policy in focus
Bloomberg’s August warning comes against a backdrop of uncertainty around South Africa’s monetary policy. The South African Reserve Bank surprised some market participants in July by leaving its policy rate unchanged at 7%, despite inflation having risen to 5% in June and remaining above the bank’s 3% target. The decision was split, adding to questions about the future direction of interest rates and the SARB’s response to inflation risks.
The rand subsequently fell by more than 2% against the dollar.
That makes Wednesday’s CPI release particularly significant. If July’s inflation rate comes in below expectations, it could give the Sarb greater scope to ease monetary policy. However, lower rates could also reduce the rand’s appeal to investors seeking higher yields.
Conversely, a stronger-than-expected inflation reading could reinforce expectations that the Sarb will keep rates higher for longer, potentially providing support for the currency.
While Bloomberg’s seasonal analysis had pointed to renewed pressure on the rand during August, a softer dollar and changing expectations around global interest rates are providing support.
For investors, Wednesday’s data could therefore provide an important signal about the balance between currency risk and the potential returns available in South African assets.
