Serbia has begun drawing on mandatory diesel reserves as refinery sanctions risk, weaker commercial imports and Danube logistics constraints tighten domestic fuel supply.
Oil company NIS has asked the U.S. Treasury for a new operating licence beyond Sept. 30, while the government said it will release another 5,000 tonnes of diesel from mandatory stocks.
Commercial importers have reduced purchases because of elevated international prices and transport constraints. Serbia expects diesel demand of about 205,000 tonnes in October, making the release modest relative to consumption but significant as a shift from tax intervention towards physical supply management.
NIS operates Serbia’s only refinery at Pančevo and remains central to the domestic fuel market. Any restriction on its operations would increase dependence on more expensive imports and regional logistics.
The government has already cut fuel excise duties to cushion consumers from higher prices. Strategic-stock releases add a second line of defence.
Regional supply options could improve after Bulgaria reopened petroleum-product exports from the Burgas refinery, while Romanian and Croatian routes could also provide replacement volumes.
But diversification would improve physical availability more than price, with European refined-product costs still elevated.
The immediate market question is whether NIS secures another U.S. licence. If uncertainty persists, Serbia will have to balance higher imports with careful use of mandatory stocks ahead of winter.
