JOHANNESBURG, May 19 – South Africa’s improving economic outlook has been clouded by the Middle East conflict, which ​is pushing up energy costs and ‌complicating monetary policy, the Institute of International Finance said on Tuesday.

• The IIF cut its 2026 growth forecast to 1.3% from 1.7% previously.

• Inflation is now ‌expected ​to average 4% this year, ⁠up from around ⁠3% expected before the war.

• South Africa increasingly reliant on Gulf Cooperation Council (GCC) for refined petroleum products, leaving it exposed to supply ​disruptions from the Strait of Hormuz.

• Diesel prices rising faster than petrol due to ⁠greater reliance on imports ⁠and weaker price regulation.

• Market pricing ​has shifted to two interest rate hikes this ​year from two cuts previously.

• The current ‌account deficit is expected to widen to 1.1% of GDP in 2026 from 0.5%.

• Fiscal deficit estimated at 4.5% of GDP for ⁠fiscal year 2025/26 which ended in March; IIF projects it narrows to 4.1% in current fiscal year.

• ⁠Government debt ‌expected to ease gradually to 77.1% ⁠of GDP in the medium-term ​from ‌a peak of 78.9% of GDP ​in fiscal ⁠year 2025/26.

• On the upside, port and rail reforms could benefit from cargo rerouting around the Cape of Good Hope; elevated commodity prices support mining investment.
