Oil price shock raises prospect of a SARB interest rate hike this month

Oil prices have soared to around $97 per barrel, the highest in recent times, following conflicts in the Middle East that have raised concerns about a potential disruption to global supply. South African consumers are already feeling the strain, with petrol prices increasing by R1.34 and diesel prices by up to R3.15 per litre. Analysts warn that oil prices could surpass the $100 mark again, leading to more substantial fuel price hikes in October, potentially exceeding R1.50 per litre for both petrol and diesel.

The International Energy Agency (IEA) has reduced its estimates for oil supply for the remainder of 2026 due to the lack of progress in reopening the Strait of Hormuz and ensuring unobstructed passage through the Bab el-Mandeb Strait. Consequently, global oil supply is projected to drop by an additional 4% in 2026.

The South African Reserve Bank (SARB) has adopted a cautious stance regarding the oil price shock and its effects on fuel prices and inflation. While the bank raised interest rates by 25 basis points in May, it maintained the rates at its April and July Monetary Policy Committee (MPC) meetings. Given the renewed flare-up in the Middle East war, the SARB might raise interest rates by another 25 basis points during its upcoming MPC meeting on the 23rd of the month. This decision will hinge on the developments in oil prices and the rand's performance.

Currently, South Africa's SARB policy rate, previously known as the repo rate, stands at 7%, while the prime lending rate is 10.5%. At the most recent MPC meeting, the vote was divided 4-2, with two members advocating for a 25-basis-point increase in the policy rate.
