South Africa's petrol price jumped 15% in a single month on 1 April 2026, driven by the US-Iran conflict, the closure of the Strait of Hormuz, and a rand that has been working against us throughout. Most South Africans are aware of what happened at the pump. What's less visible is how this plays out inside your online store.

A fuel shock of this scale does not stay at the petrol station. It moves.
Taxis and buses have already warned of fare increases. For commuters spending 40% of their salary on transport, these hikes could push that figure over 50%. That is money that was available for discretionary spending — including online shopping — now gone before it reaches a checkout.
Sharp increases at the pumps typically translate into higher public transport fares and rising food prices, as the cost of moving goods from farms and factories to retailers climbs. Grocery bills go up. Electricity went up on the same day. Everything essential is more expensive simultaneously.
Your customer has not lost their desire to shop online. They have lost the budget margin that made it easy.
On top of softer demand, your cost to fulfil is rising. The Courier Guy announced a temporary fuel surcharge for customers shipping parcels by air — the first time the delivery company has introduced such a measure — after airlines applied ticket price increases directly to cargo operations.
According to Garry Marshall, CEO of the South African Express Parcel Association, for ecommerce specifically, margins are so thin that the ability to absorb fuel price increases is severely limited. That is an industry body saying out loud what most merchants are quietly calculating right now.
The combination is the problem. Consumers buying less, and each sale costing more to fulfil. That double compression is where margin goes to die.
Check your free-shipping threshold. If you set it more than a few months ago, it is probably no longer covering your actual delivery cost.
Review your courier levy structure. Understand exactly what the fuel component is on each shipment type and whether your product pricing reflects it.
Do not wait for May. The government's R3/litre levy relief expires on 5 May and may not be extended. Model your numbers on the assumption it isn't.
The merchants who navigate this well are not the ones who absorb everything in silence or panic-raise prices. They are the ones who understand their numbers clearly enough to make a deliberate call.
