Recent market data indicates that Serbia and Montenegro are experiencing significant pricing disparities compared to their South-East European counterparts. As of February 24, 2026, the base price on Serbia’s SEEPEX was recorded at 56.31 EUR/MWh, while Montenegro’s BELEN cleared at 40.00 EUR/MWh. In contrast, Hungary’s HUPX reported a price of 115.25 EUR/MWh, with Slovenia and Croatia also exceeding 110 EUR/MWh. This persistent discount is not attributed to oversupply but rather reflects inherent structural characteristics within these markets.
A key factor contributing to these discounts is the limited liquidity in both SEEPEX and BELEN, which operate with significantly lower trading volumes than other regional exchanges such as HUPX, OPCOM, or BSP. The reduced participation from international trading firms leads to thinner order books and a heightened execution risk. Consequently, bids in these markets often reflect conservative valuations adjusted for risk rather than the marginal costs of production, which hinders effective price formation under typical market conditions.
The balancing exposure further exacerbates the pricing discrepancies faced by traders in these markets. Both Serbia and Montenegro are characterized by limited reserve margins and restricted access to fast-ramping capacity. This situation becomes particularly problematic during forecast errors, such as wind shortfalls or sudden spikes in demand, where imbalances must be addressed through mechanisms that lack sufficient price transparency. Traders tend to preemptively price this uncertainty into their bids, leading to lower day-ahead prices as a strategy to mitigate potential imbalance settlement risks.
Additionally, interconnection asymmetries play a crucial role in shaping market dynamics. Although both Serbia and Montenegro are linked to higher-priced neighboring markets, congestion often restricts export capabilities during peak demand periods. This situation limits arbitrage opportunities when price differentials would typically encourage cross-border trading. Traders thus encounter asymmetric exposure: local prices may decline while the potential for higher prices remains contingent on uncertain access to neighboring markets.
The analysis suggests that the structural discounts observed in Serbia and Montenegro arise from their classification as higher-risk environments rather than simply being low-cost systems. Notably, during periods of regional stress, these discounts can diminish rapidly—often within a single trading session—highlighting the optionality present within these markets despite their inherent volatility.
