Serbia’s latest exchange with the International Monetary Fund has put three politically sensitive issues back into the centre of economic policy: household electricity prices, motorway tolls and the future ownership of Naftna industrija Srbije. Behind the technical language of the IMF’s third review under the Policy Coordination Instrument lies a clearer message to investors and creditors. The government is trying to preserve the fiscal anchor of 3% of GDP, but that increasingly depends on allowing regulated prices to move, keeping energy subsidies temporary and preventing state-owned companies from becoming a larger burden on the budget.
The most visible commitment is electricity. The Serbian authorities have told the IMF that they remain committed to regular indexation of household electricity prices in line with inflation and intend to propose the next adjustment by the end of 2026. The timing has not been fixed, which leaves political room around the autumn and winter heating season, but the direction is no longer ambiguous. Electricity prices are expected to rise again, not as a one-off crisis measure, but as part of a broader return toward cost-reflective tariffs.
For households, the language sounds technical. For EPS, lenders and the fiscal authorities, it is much more direct. Serbia’s power system still needs heavy investment in generation, mining, grid reliability, environmental compliance and new renewable integration. Keeping household tariffs artificially low would preserve short-term political comfort but weaken the financial position of energy companies precisely when the sector is expected to carry a larger investment cycle. The IMF’s signal is that price discipline is not only an energy issue. It is a sovereign-risk issue.
The government has also committed to reviewing the current block-tariff structure by the end of August 2026. Serbia’s household tariff system already differentiates consumption through the green, blue and red zones, with the cheapest electricity applying to consumption up to 350 kWh, the middle tariff applying from 351 kWh to 1,200 kWh, and the highest tariff applying above 1,200 kWh. The shift made in 2025, when the red-zone threshold was lowered from the previous 1,600 kWh, already pushed high-consumption households into more expensive billing bands. Any further reform of the block system would therefore be more than a technical adjustment. It would decide how much of the burden is carried by average households, high-consumption users and politically protected customer groups.
The same fiscal logic appears in road tolls. The government has informed the IMF that tolls will be indexed again in July 2026, following an increase of 4.3% in July 2025 and a further adjustment in January 2026 on sections involving bridges and tunnels. The measure is designed to strengthen the revenue base of Putevi Srbije, a public company that has become one of the fiscal-risk points watched by the IMF. The issue is not only the price of using motorways. It is whether road infrastructure spending, maintenance obligations and debt-like pressures remain inside a disciplined fiscal framework or gradually migrate into arrears and quasi-fiscal liabilities.
For transport companies, logistics operators and exporters, higher tolls will feed directly into operating costs. Serbia’s industrial and trade model depends heavily on road transport links to the EU, the Adriatic and regional supply chains. Even moderate toll indexation matters when diesel, driver costs, financing and border delays are already pressuring margins. But from the state’s perspective, the alternative is also costly: underfunded road infrastructure ultimately reappears as unpaid bills, delayed maintenance or future budget transfers.
The most strategically important part of the IMF review concerns NIS. The government’s wording suggests that Serbia is preparing for a final fallback option if negotiations between Gazprom Neft and potential buyers, including MOL, fail to remove the sanctions risk. The Pancevo refinery is described as macroeconomically important, which is an understated way of saying that Serbia cannot allow its core oil-processing asset to become commercially paralysed. The refinery sits at the intersection of fuel supply, petrochemicals, budget revenue, foreign policy and sanctions exposure.
The authorities have told the IMF that they are monitoring negotiations between existing shareholders and potential buyers and expect a solution that would allow sanctions to be lifted. But the important part is the contingency language. Should negotiations fail, Serbia says it would take the necessary executive and legislative measures to resolve the situation. The report also states that any acquisition of an ownership stake in NIS by the Republic of Serbia would be treated as a below-the-line acquisition of financial assets and would not affect the official fiscal deficit.
That accounting distinction matters. It means a potential state acquisition of NIS shares could be structured in a way that does not immediately widen the headline deficit. But it would still affect public-sector exposure, financing needs and political risk. A state move into NIS would not be a normal portfolio transaction. It would be an emergency intervention in a systemically important energy company, driven by sanctions, refinery continuity and geopolitical constraints. For bond investors and banks, the key question would not be only whether the transaction is booked above or below the fiscal line, but whether it creates new contingent liabilities for the state.
The IMF review also reveals the tension between fiscal discipline and domestic politics. While President Aleksandar Vučić has publicly discussed support for pensioners, including spa vouchers, cheaper medicines and possible one-off payments, the authorities’ letter to the IMF states that pensions will be adjusted strictly according to the annual indexation formula under the pension and disability insurance law. In plain terms, the government has committed to no ad hoc pension increases and no one-off pensioner bonuses outside the legal mechanism.
That commitment is not minor. Pension spending is one of the largest and most politically sensitive components of Serbia’s budget. Extraordinary payments may be popular, especially before elections, but they weaken predictability and complicate the credibility of fiscal rules. The IMF’s position is familiar: pension increases should follow the formula, not the electoral calendar. The market will watch which commitment proves stronger.
Fuel policy is another test. Serbia reduced fuel excise duties after the oil-price shock linked to the Middle East crisis, first by 20% in March and then temporarily by a further 5% until mid-May, before returning the reduction to 20%. The IMF estimates that the measure cost the budget around 0.06% of GDP per month. The authorities now say that, under the baseline scenario in which oil prices remain broadly around current levels, reduced fuel excises should be phased out by July 2026.
The fiscal logic is clear. Fuel-tax cuts cushion consumers quickly, but they are expensive, broad-based and poorly targeted. They also distort the price signal at exactly the moment when the IMF wants Serbia to preserve fiscal space for investment and targeted social support. The authorities have left room for temporary measures if oil prices rise sharply and persistently, including deeper or extended excise cuts, use of product reserves, support for district-heating companies, assistance for vulnerable businesses and expanded protection for energy-poor households. But the cost of such measures could reach up to 2% of GDP, or roughly €2bn, in the remaining part of this year and the beginning of next year. That number explains why the IMF wants any support to be time-limited, targeted and built into the existing fiscal ceiling rather than layered on top of it.
Serbia’s energy-security buffer is not unlimited. The government says oil and petroleum-product reserves cover around 63 days of imports, with a target of 90 days when conditions allow. Gas reserves of around 600mn cubic metres are described as sufficient to cover consumption until October, helped by lower summer demand, with scope to last longer in case of disruption. These figures are reassuring on paper, but they also show the scale of exposure. Serbia’s fiscal position, fuel market and industrial continuity are all sensitive to external shocks that the government cannot fully control.
The IMF is also pressing for deeper restructuring at EPS and EDS. It wants the authorities to adopt and implement a time-bound plan for workforce rationalisation and external-service costs at EPS, with a similar plan being prepared for the electricity distribution company. The government says optimisation of support-function staffing at EPS should begin by the start of 2027. That phrasing suggests a politically managed process rather than an abrupt downsizing, but the direction is evident. EPS is being pushed to become a more investable, better governed utility, not merely a vehicle for price control and employment protection.
For Serbia’s power sector, this is the critical institutional issue. Higher tariffs alone do not make EPS bankable if governance, procurement, staffing, receivables and investment discipline remain weak. The IMF’s emphasis on cost-recovery tariffs comes together with stronger payment discipline among major debtors, better governance and timely restructuring. That is also where the reform becomes commercially relevant for renewable developers, equipment suppliers, lenders and grid investors. A financially strained EPS and EDS slow the entire electricity transition. A more disciplined sector can support larger capital investment, but only if tariff reform is matched by credible internal restructuring.
The authorities have also pledged not to introduce or tighten price controls, margin caps or interest-rate limits in the private sector without prior consultation with the IMF. That commitment matters after a period in which governments across the region have used administrative measures to contain food, fuel and retail-price pressures. The IMF’s concern is that such measures may look attractive in the short run but weaken market signals, distort private-sector behaviour and create hidden fiscal or financial costs. Serbia is effectively being asked to choose rules-based policy over ad hoc intervention.
The overall macro picture gives the government some room, but not enough to avoid difficult choices. Serbia’s economy grew by 2% in 2025, while the IMF projects growth of about 2.8% in 2026 and 4% in 2027. Inflation remains within the National Bank of Serbia’s tolerance band, but energy prices, household credit growth and geopolitical shocks keep risks tilted to the downside. Public debt remains moderate, reserves are strong and the banking sector is well capitalised. Those buffers are valuable. They are also the reason the IMF wants policy discipline preserved before pressure becomes more expensive.
The political challenge is that nearly every reform item touches a sensitive constituency. Electricity tariffs affect households. Tolls affect drivers, hauliers and exporters. Fuel excise normalisation affects nearly everyone through pump prices and logistics costs. Pension discipline affects the largest electoral bloc. EPS rationalisation affects employment and local political networks. NIS touches energy security, Russia, Hungary, the United States, refinery operations and Serbian industrial supply chains.
For investors, the IMF review reads less like a narrow macroeconomic document and more like a map of Serbia’s next policy tests. The country is not being asked to impose austerity in the classic sense. It is being asked to stop hiding costs in state-owned companies, regulated tariffs, temporary subsidies and politically timed payments. That is a harder task than passing a single budget measure because it requires consistency across electricity bills, motorway tolls, fuel taxation, public enterprises and strategic assets.
The decisive issue over the next six months will be credibility. Serbia can keep the 3% of GDP fiscal ceiling and still face rising market concern if investors conclude that energy, roads, pensions or NIS are being managed through postponement rather than resolution. Equally, the country can absorb moderate tariff and toll increases if they are presented as part of a coherent investment and fiscal-risk strategy rather than as isolated price hikes. The IMF has put the framework on paper. The test now moves to implementation, where Serbia’s economic policy has often been strongest in negotiation and more uneven in delivery.
