Recent data from 25 February 2026 highlights the complexities of price spreads and forward markets in South-East Europe (SEE), revealing how these mechanisms reflect the region’s evolving electricity landscape. While spot prices indicate immediate market pressures, forward curves provide insights into anticipated fuel costs, carbon pricing, and regulatory conditions. The analysis shows that SEE’s forward markets remain fragmented, characterized by persistent basis risk between trading hubs and limited liquidity outside of Central European exchanges.
Spot market prices exhibit significant variation, with HUPX reporting at 107.7 EUR/MWh, BSP at 100.4 EUR/MWh, and CROPEX at 94.1 EUR/MWh. A second tier includes OPCOM at 59.0 EUR/MWh, HENEX at 54.5 EUR/MWh, SEEPEX at 53.6 EUR/MWh, BELEN at 54.5 EUR/MWh, and ALPEX at 45.5 EUR/MWh. These discrepancies are not resolved by forward markets; rather, they formalize existing gaps through basis spreads that necessitate active management by traders and utilities.
The relationship between Hungary and Germany serves as a critical indicator of market dynamics. On the same date, the HU–DE spot spread was recorded at 13.7 EUR/MWh, highlighting a continued decoupling from the German reference hub due to constrained cross-border capacity and varying generation mixes. This spread reflects ongoing HU–DE basis risk in the forward market rather than any convergence.
Forward contracts for Week 10 illustrate heightened stress in the Hungarian market, where prices fell sharply by -8.17%, contrasting with declines of -1.16% in Germany and -0.48% in Italy. This volatility underscores the sensitivity of SEE-adjacent markets to marginal changes in system balance and fuel availability. Forward curves in Hungary incorporate expected fuel costs alongside congestion risks and regulatory uncertainties.
Hungarian forward prices were noted at 95.50 EUR/MWh for WK10 and 99.00 EUR/MWh for WK11, with March-26 trading around 91.50 EUR/MWh and Cal-26 near 95.00 EUR/MWh. These figures suggest a normalization trend relative to peak spot prices but do not indicate a return to lower pricing levels typical of Balkan markets, instead reflecting sustained premiums linked to gas pricing and cross-border dependencies.
Gas forwards further substantiate this trend, with the Austrian CEGH gas contract for March-26 trading at 33.26 EUR/MWh and Q2-26 at 33.00 EUR/MWh, indicating that gas-fired generation remains a primary source during peak hours in Hungary and neighboring regions. The forward power curve thus continues to account for gas volatility rather than a shift toward renewable energy dominance.
Carbon pricing is another influential factor shaping forward spreads; EUA Dec-26 contracts increased by 2.17%, adding upward pressure on thermal generation costs across coal-heavy systems in the region. On February 25, coal forward indicators (API-2) were around 107–108 EUR/MWh equivalent, signaling that coal is no longer a cost-effective anchor for SEE markets.
The interplay between gas, coal, and carbon pricing creates an environment where thermal marginality is both costly and unstable. Consequently, forward curves in Hungary, Slovenia, and Croatia reflect higher premiums compared to Balkan markets, even during periods of reduced spot prices due to hydro or solar output fluctuations.
The depth of forward markets varies significantly across the region; HUPX and BSP provide adequate liquidity for week-ahead, month-ahead, and calendar products, enabling utilities to hedge their exposure effectively. Conversely, platforms like SEEPEX, BELEN, and ALPEX lack substantial liquidity, compelling participants to utilize proxy hedges through Hungarian or Slovenian contracts—leading to embedded basis risk that cannot be entirely mitigated.
A Serbian utility hedging through HUPX faces a disconnect between the current spot price of 53.6 EUR/MWh on SEEPEX and forward levels ranging from 95–100 EUR/MWh in Hungary. Although cross-border flows offer some arbitrage opportunities, congestion and regulatory barriers inhibit full price alignment.
This basis risk is asymmetric; Hungarian traders hedging against Balkan markets face less uncertainty since downstream markets typically clear at discounts. In contrast, Balkan traders encounter both price level risks and volume uncertainties during peak demand or low hydrology periods—reinforcing the structural hierarchy within SEE trading.
Renewable energy sources add complexity to these dynamics; on February 25th, wind and solar generation reached a total of 5,704 MW—lowering midday prices but elevating evening peaks. Forward curves increasingly reflect this daily variability with peak products commanding higher premiums compared to baseload offerings.
Storage solutions are beginning to impact forward expectations but have yet to significantly alter market dynamics on a regional scale. Bulgaria’s battery system capacity of 124 MW / 496.2 MWh illustrates potential for stabilizing cash flows; however, current storage volumes are inadequate for arbitraging multi-day or seasonal price spreads.
The evolving structure of SEE forward markets indicates a shift towards spread-based hedging strategies rather than outright price bets; traders are focusing more on differentials such as HU–DE, HU–BSP, and HU–CROPEX instead of absolute price movements—reflecting enduring system characteristics over transient fluctuations.
From an investment perspective, sustained forward premiums above 90 EUR/MWh in Hungary and Slovenia signal opportunities for flexible asset development like gas peakers or storage systems while lower price ranges (50–60 EUR/MWh) in Balkan markets hinder new thermal capacity investments.
This divergence has significant long-term implications; as carbon pricing intensifies and gas market volatility persists, SEE forward curves are likely to steepen rather than flatten over time—prompting earlier risk pricing in markets closely tied to EU hubs while peripheral areas may experience delayed adjustments followed by abrupt repricing when constraints arise.
The data from late February emphasizes that SEE’s forward markets serve as instruments for risk allocation rather than convergence mechanisms—they codify structural differences among various markets while conveying expectations regarding fuel costs and carbon pricing trends that shape hedging behaviors accordingly.
As participants navigate these complexities within SEE power markets, understanding forward dynamics becomes crucial; while spot prices may fluctuate daily, it is the underlying spreads that reveal deeper architectural dependencies within the system—highlighting how unresolved basis risks will continue to reflect entrenched structural asymmetries across South-East Europe’s energy landscape.
