Serbia will reduce fuel excise duties by the maximum permitted 20% for one week, intensifying its fiscal intervention as international supply disruptions threaten to raise transport costs and consumer prices.
The lower rates will apply from 20 to 26 July. Excise duty on unleaded petrol will fall to RSD57.60 per litre, while the duty on diesel will decline to RSD59.23. The rate on leaded petrol will be RSD61.24.
The measure replaces a smaller 10% discount in force from July 13 to July 19. Compared with that arrangement, the additional reduction amounts to RSD7.20 per litre for unleaded petrol and RSD7.41 for diesel.
If the reduction is passed through completely, the retail effect should be slightly larger once value-added tax is included. The theoretical saving is about RSD8.64 per litre for petrol and RSD8.89 for diesel, although the actual movement at filling stations will also reflect wholesale prices, exchange rates, inventories and Serbia’s regulated weekly price formula.
The government described the measure as a way to protect supply stability and insulate the domestic market from disruptions in international trade. It has used excise adjustments repeatedly during 2026, lowering duties when crude-oil prices rose and gradually restoring them when pressure eased.
That flexibility gives the authorities an immediate anti-inflation tool. Diesel prices feed directly into road haulage, agriculture, construction and distribution. A sharp increase can spread quickly through food and consumer-goods prices, while also reducing the margins of companies unable to pass higher transport costs to customers.
The intervention transfers part of the shock from consumers to the budget. Earlier government estimates indicated that maintaining a 20% excise reduction could cost approximately RSD4.1bn a month, or about €35mn, although the actual loss depends on fuel consumption and the period for which the discount remains in force.
For a one-week measure, the direct fiscal impact is manageable. The greater risk is that repeated extensions turn temporary relief into a semi-permanent commitment. Once businesses and households adjust to lower tax-inclusive prices, restoring the full duty can itself become an inflationary and politically difficult decision.
The policy also complicates the assessment of underlying price pressures. Lower excise duties can suppress headline inflation temporarily without reducing the external cost of imported energy. When the measure expires, the tax component returns unless international prices have fallen sufficiently to offset it.
Fuel distributors face a separate timing issue. Companies may have acquired stocks under one duty regime and sold them under another, while regulated retail-price changes do not necessarily coincide with their procurement cycle. Smaller operators with limited storage and working capital may be more exposed than vertically integrated businesses.
Serbia’s decision is therefore less a conventional tax cut than a short-term price-stabilisation mechanism. Its effectiveness will depend on whether the full reduction reaches motorists and transport companies and whether international oil prices ease before the duty discount expires.
The next government decision, rather than the seven-day measure itself, will show whether Belgrade believes the disruption is temporary or is preparing for a longer period of expensive energy and reduced excise revenue.
