The Fuel Shock: What Happened on 1 April

At midnight on 1 April 2026, South Africans woke up to the most dramatic fuel price adjustment in the country's history. The numbers are severe. Diesel rose by R7.37 to R7.51 per litre in a single month, the largest one-time diesel increase ever recorded. Petrol rose by R3.06 per litre, but only because the Treasury intervened with a R3 per litre emergency fuel levy cut. Without that relief, the petrol increase would have been R5 to R6 per litre.

The Treasury's R3 per litre levy relief is costing the government approximately R6 billion per month and will be re-evaluated monthly. It is a fiscal band-aid, not a structural fix. If oil prices remain elevated through May, the next adjustment on 6 May could bring further pain. Early Central Energy Fund data from the first day of the May review period showed an under-recovery of R7.88 per litre for petrol 95 and a staggering R17.57 for diesel, though these figures shifted significantly within 24 hours.

Before the official price increase even took effect, panic buying hit forecourts across the country. Agricultural supplier Oos-Vrystaat Kaap (OVK) temporarily closed its diesel ordering book. NWK Limited in the North West restricted purchases to 80 litres per day. The Fuel Industry Association of SA confirmed an increase in the number of stations running out of diesel, though the Department of Mineral and Petroleum Resources insisted there was no national shortage.

May outlook: it could get much worse

Early Central Energy Fund data for the May review period (27 March to 30 April) is alarming. On the first day of the new review period, under-recoveries stood at R7.88 per litre for petrol 95 and R17.57 per litre for diesel. While those figures pulled back by over R1 (petrol) and nearly R3 (diesel) within 24 hours, the trajectory remains deeply concerning. If current market conditions hold, projections point to a petrol increase of R5.18-5.55 per litre and a diesel increase of R14.09-14.15 per litre on 6 May.

The MPC left the repo rate unchanged at its March meeting but materially revised its inflation outlook. PSG's chief economist Johann Els sees at least one 25 basis point rate hike as the "milder scenario." Investec's Annabel Bishop noted that the investor climate improvements of the past 18 months have meant the rand and bond market have been less severely impacted than they would have been under the investor climate of early 2024 or prior, but the pressure is real and building.

Why: The Iran War and SA's Refinery Problem

Two forces have converged. The first is international: the 2026 Iran conflict and the closure of the Strait of Hormuz in March 2026 triggered what the IEA called the largest supply disruption in the history of the global oil market. Brent crude, which long-term forecasts had pegged at around $60/barrel for 2026 due to oversupply, shot above $115 at peak before settling around $107. Saudi Arabia, which supplies most of South Africa's fuel, ships through routes affected by the conflict.

The second force is domestic, and it is the more troubling one. South Africa now refines less than 35% of its own fuel, down from approximately 80% previously. The closure of the Sapref refinery in Durban in 2022 was the most significant blow. Only three domestic producers remain: Natref in Sasolburg, Astron Energy in Cape Town, and Sasol's Secunda coal-to-liquids plant. This means that South Africa is a price-taker in the global refined fuel market, exposed to both crude oil prices and the rand/dollar exchange rate simultaneously.

At the Southern Africa Oil and Gas Conference in Cape Town in March 2026, minister Gwede Mantashe acknowledged that the long-term solution lies in domestic fuel production, but added that environmental objections continue to delay exploration and development. This is a structural vulnerability that predates the current crisis and will outlast it.

The interest rate trap

The macroeconomic fallout is already visible. The South African Reserve Bank had been signalling a cautious interest rate cutting cycle before the fuel spike. That expectation is now reversed. According to Momentum Investments' chief economist Sanisha Packirisamy, forward-rate agreements have moved from pricing in two rate cuts by early 2027 to three rate hikes in the same period. Investec's Annabel Bishop warned that if fuel prices are not quickly reversed in May, the impact on GDP growth will be material.

No Loadshedding: Eskom's Quiet Turnaround

Against the backdrop of the fuel crisis, a remarkable and largely under-reported story continues to unfold. South Africa reached 300 consecutive days without loadshedding on 12 March 2026. In the entire 2025 calendar year, the country experienced only 26 hours of loadshedding, all of it in April and May 2025 across four evenings. Compare that to 2023, which was the worst year in South African history for power cuts.

The numbers behind the turnaround are structural, not cosmetic. The Energy Availability Factor (EAF), which measures what share of Eskom's generation fleet is actually available to produce electricity, has risen to 65.85% for the financial year to date (April 2025 to March 2026). Two years ago, baseload unit availability was around 9%. It is now above 98%. Unplanned outages have fallen by 53%, from an average of 15,382MW to 7,224MW during the same week in March.

This is significant in the context of the fuel crisis: Eskom's reduced diesel dependence means the oil price shock is hitting the utility far less than it would have two years ago. The irony is striking. In 2023, Eskom was burning diesel at catastrophic rates to keep the lights on. In 2026, the utility is barely using it, even as the global price of diesel has reached record levels.

But don't call it fixed

The Generation Recovery Plan is delivering results, but Eskom's fleet is old and the underlying infrastructure risks have not disappeared. The 70% EAF target has been exceeded on 83 occasions, but it has not been sustained consistently. Illegal connections and meter tampering continue to strain the network. Installation teams face intimidation and violence; approximately 122,000 planned smart meter installations have been delayed as a result. And the 8.76% tariff hike that took effect on 1 April 2026 is a reminder that keeping the lights on is not free. Municipal tariff adjustments of approximately 9% will follow from 1 July 2026.

The Solar Boom and Cape Town's SSEG Rules

If the fuel crisis is the bad news and Eskom's turnaround is the good, then rooftop solar is the future, albeit one tangled in red tape. South Africa's cumulative installed solar capacity now exceeds 10 GW, with 1.6 GW deployed in 2025 alone. In Cape Town, the City is processing more than 1,500 small-scale embedded generation (SSEG) applications per month, a number that has grown sharply since the loadshedding crisis of 2023 convinced thousands of homeowners and businesses to invest in panels and batteries.

But the rules governing these installations are a source of growing frustration. The City of Cape Town requires SSEG registration for all grid-tied systems, even those that do not export power back to the grid. Since October 2023, even "standby" or battery-only systems must be treated as grid-tied for safety and regulatory purposes. The rationale is sound: incorrect wiring has caused fires and power quality issues. But the compliance burden is significant.

What Cape Town requires

The reward: Cash for Power

For those who navigate the process, the incentives are meaningful. Cape Town's "Cash for Power" programme allows registered grid-tied systems to sell surplus electricity back to the City at a feed-in tariff of approximately R0.87 per kWh for residential users. The credit appears on your municipal bill. You will need a bi-directional AMI meter (Advanced Metering Infrastructure), which comes with a small monthly administration fee, but the ongoing savings on electricity bills, combined with the feed-in income, typically deliver a payback period of 4 to 7 years depending on system size and consumption patterns.

Eskom's fee waiver: extended to September 2026

On 2 April 2026, Eskom confirmed that its registration fee waiver for SSEG systems up to 50 kW has been extended to 30 September 2026. The waiver, originally set to expire in March 2026, covers application, tariff conversion, and connection fees. This applies to Eskom-supplied customers, not municipal customers (Cape Town residents are municipal customers and subject to the City's own fee structure). But the South African Photovoltaic Industry Association (SAPVIA) is pushing for municipalities to follow Eskom's lead and simplify their processes.

What It All Means for Cape Town

These three forces are not separate stories. They are deeply interconnected, and for Cape Town residents and businesses, they point in a clear direction.

The fuel price SVG: how bad is it?

The chart shows that while April 2026's petrol price is not the all-time record (that was set in July 2022 at R26.64/l during the Ukraine conflict), the trajectory is alarming because it comes after a period of relief. The March 2026 price of R19.47 had given consumers breathing room. The R3.06 jump in a single month, even after the R3 levy relief, is a shock to household budgets. And May could be worse.
