Serbia’s legal-reform environment in 1H 2026 moved on two tracks. On the technical side, the country continued aligning parts of its financial, payments, energy-market and administrative framework with EU systems. On the political and institutional side, the accession process remained constrained by rule-of-law concerns, judicial independence, media freedom, electoral reform and the Kosovo normalisation condition. That makes Serbia very different from Montenegro: the issue is not whether Belgrade can draft more EU-style laws, but whether those laws are adopted transparently, enforced independently and trusted by Brussels, investors and domestic institutions.
Formally, Serbia is still a candidate country with accession negotiations open since January 2014. The official status remains 22 of 35 chapters opened, with only two provisionally closed. The European Commission has confirmed that Cluster 3 — competitiveness and inclusive growth is technically ready to open, but also states that the overall pace of negotiations will continue to depend on rule-of-law reforms and the normalisation of relations with Kosovo. That is the core legal-political constraint on Serbia’s accession file: market chapters may be technically prepared, but the fundamentals continue to decide the speed of the process.
Belgrade tried to show renewed administrative discipline at the start of the year. On 26 January 2026, the Serbian government adopted a decision establishing a new high-level Operational Team for the EU accession process, designed to coordinate accelerated implementation of obligations across institutions. Serbia’s Reform Agenda under the EU Growth Plan contains 98 reform steps, divided into 26 steps for business environment and private-sector development, 39 for green and digital transition, 12 for human capital and 21 for fundamentals and rule of law. The available EU envelope is around €1.58bn until the end of 2027, but disbursement is conditional, including on rule of law and constructive engagement in the Belgrade–Pristina dialogue.
The main rupture in 1H 2026 came from the judiciary. Serbia adopted amendments on 28 January 2026 affecting the Law on the Public Prosecutor’s Office, the High Prosecutorial Council, cybercrime jurisdiction, judges and the territorial structure of courts and prosecution offices. The government presented the changes as efficiency and coherence measures, but the EU and the Venice Commission treated them as a major rule-of-law problem. EU Enlargement Commissioner Marta Kos warned in February that the amendments were “eroding trust” and that the EU could withhold funds from Serbia’s €1.6bn Growth Plan allocation because the funding carries rule-of-law preconditions.
The Venice Commission’s April opinion deepened the problem. It found that changes of such importance required meaningful public debate, stakeholder consultation and impact assessment, but concluded that those elements were missing. It also said the amendments removed safeguards protecting prosecutorial autonomy and issued recommendations covering hierarchical control, provisional appointments, temporary assignments, the status of prosecutors in the organised-crime prosecution office, cybercrime prosecutorial autonomy and the renewal of court presidents’ mandates. For investors, this matters directly. Judicial autonomy is not an abstract accession issue; it affects contract enforcement, corruption investigations, procurement disputes, concession challenges, bankruptcy proceedings, regulatory appeals and the credibility of public-sector counterparty risk.
The political message from Brussels in June was therefore unusually direct. During his Belgrade visit on 4 June 2026, European Council President António Costa said the pace of progress depends on Serbia’s own resolve and named rule of law, electoral reform and media freedom as areas where reforms need to accelerate. That places Serbia’s legal environment in a conditionality corridor: Brussels is still offering deeper integration, but the price is no longer only legislative alignment. It is institutional behaviour.
At the same time, Serbia recorded one important practical integration gain. On 5 May 2026, 18 Serbian banks officially joined the SEPA schemes, making euro payments between Serbia and the EU faster, cheaper and more reliable. The European Commission estimated potential savings of up to €400m for individuals and businesses. This is one of the most commercially relevant accession-linked reforms of the year, particularly for exporters, SMEs, IT firms, logistics companies, industrial suppliers and cross-border service providers. It brings Serbia closer to the EU payments infrastructure even while the formal accession process remains politically slowed.
The energy-market reform track also moved forward. On 5 May 2026, SEEPEX introduced negative prices on day-ahead and intraday markets, with the first delivery date on 6 May 2026, and aligned minimum price limits with EU reference thresholds. The Energy Community described this as progress in implementing the Electricity Integration Package and a step toward market coupling with the EU internal electricity market. For Serbian renewable developers, traders, balancing responsible parties, battery investors and lenders, this is a legal-market turning point: the market is moving from administratively protected price signals toward EU-style volatility, flexibility pricing and curtailment discipline.
Public procurement remains the largest business-environment weakness. The Commission describes Serbia as only moderately prepared in public procurement and notes limited progress, despite some improvement in green and social procurement. More importantly, it continues to criticise the use of intergovernmental agreements and special laws to bypass ordinary procurement rules, including for EXPO Belgrade 2027 and certain strategic energy projects. In 2024, Serbia’s public procurement market represented 10.87% of GDP, while the total value of contracts exempted from the Public Procurement Law fell from €7.1bn to €5.7bn, still a very large number. The share of tenders with only one bid remained around 50.75%, which keeps competition, transparency and corruption risk high on the EU accession agenda.
Environment and climate law is another structural bottleneck. Serbia has made progress through improved EIA and SEA legislation, air-quality law, MRVA rules for stationary installations, a waste-prevention plan and hazard-risk legislation. But the Commission still classifies Serbia as having only some level of preparation in environment and climate change, with implementation capacity and administrative systems still needing major improvement. For heavy industry, mining, steel, cement, chemicals, aluminium, electricity and CBAM-exposed exporters, this means the accession legal environment is moving toward more demanding measurement, permitting and reporting obligations, even before formal EU membership.
The investor reading is therefore mixed. Serbia is becoming more integrated with EU technical systems in payments and electricity trading, and parts of the acquis are advancing through sectoral laws, by-laws and administrative coordination. But the legal environment still carries a heavy governance discount. The rule-of-law dispute in 1H 2026 has made accession funding, chapter movement and investor confidence more conditional on whether Serbia can reverse or repair controversial judicial changes, strengthen prosecutorial independence, improve media and electoral conditions, and reduce the use of exceptional legal regimes in procurement.
For business, the practical conclusion is that Serbia should now be treated as an EU-converging market with non-EU enforcement risk. Payment flows, power trading and selected regulatory fields are becoming more European. Courts, procurement, concessions, public projects, environmental enforcement and politically sensitive sectors remain areas requiring stronger due diligence. The companies best positioned for the next phase will be those that structure contracts, compliance systems, project documentation and financing assumptions against future EU standards, while still pricing today’s Serbian institutional and political risk into every transaction.
