Escalating tension in the Middle East is increasing the risk premium on global oil and shipping routes, which is the quickest channel through which South African consumers could feel the shock via higher fuel and imported-goods costs, according to PwC Africa chief economist Lullu Krugel’s assessment of the situation. Even before any formal disruption, markets typically price in uncertainty through more expensive crude, higher marine insurance and volatile exchange rates, all of which can filter into local prices.
For a South African household, the most immediate “direct cost” is transport: if international oil prices remain elevated or spike, the monthly petrol price adjustment can rise, pushing up the cost of commuting, school runs and essential travel. For households that rely on minibus taxis or buses, higher fuel costs tend to translate into fare increases over time, while delivery fees and courier charges also become more expensive as transport operators try to recover input costs.
The second-round effect is on everyday groceries and household essentials. South Africa imports a meaningful share of refined fuel, chemicals and certain food inputs, so a weaker rand—often seen during global risk-off periods—can raise the shelf price of items priced off global markets or paid for in dollars. This matters most to lower- and middle-income households because transport and food take up a larger portion of monthly budgets, and price increases are harder to absorb without cutting back elsewhere.
Krugel’s warning also has implications for inflation expectations: if fuel and imported input costs stay higher for long enough, overall inflation can become stickier, keeping pressure on the cost of living and increasing the risk that interest rates stay higher for longer. In practical terms, households can limit exposure by tightening fuel usage where possible (trip consolidation, lift clubs, choosing more fuel-efficient commuting options) and by reviewing monthly budgets early, because the earliest signs of a geopolitical shock usually show up first in fuel-related spending and then in food and services.
