As of January 2026, the energy markets in South-East Europe (SEE) are undergoing significant transformations, characterized by an accelerated emergence of trading signals and a more complex interplay between gas and electricity pricing. This shift indicates a deeper structural interconnection among various market elements, including gas supplies, electricity generation, storage capabilities, and cross-border trading activities.
Recent data reflects that Romania and Hungary have established themselves as critical marginal pricing hubs, with average electricity prices recorded at €150.51/MWh and €150.41/MWh respectively. These figures are indicative of the region’s exposure to gas marginality and variations in hydroelectric output. The speed at which price signals transmit from these countries to neighboring markets such as Croatia, Serbia, and Bulgaria has been notably rapid, often occurring within a 24 to 72-hour window when market conditions shift.
The implications for energy traders are profound; monitoring the dynamics between Romania and Hungary is essential for anticipating price movements throughout the region. As these two nations exert substantial influence over pricing trends, peripheral markets may lag behind in their responses to upstream changes.
In January, hydroelectric power played a pivotal role in dampening short-term volatility across the region. Serbia experienced a remarkable increase in hydro output by approximately 186%, while Greece saw an increase of around 155%. This surge allowed both countries to mitigate the impacts of rising gas prices even as demand escalated. However, this stabilization is expected to be temporary; once hydroelectric production normalizes, markets may revert to gas-driven pricing mechanisms that could result in sharp upward adjustments.
The TTF (Title Transfer Facility) gas price has also emerged as a critical factor influencing market behavior. A notable threshold was identified at €40/MWh; breaching this level has reactivated gas marginality across SEE power markets. The consequences of surpassing this threshold include heightened control by gas prices in Hungary, Romania, Italy, and Bulgaria, as well as steepening forward curves for power prices that reflect anticipatory rather than reactive pricing strategies.
Storage capacity remains another crucial element affecting market stability. Mid-January saw storage levels drop to approximately 49-51%, significantly below the five-year seasonal average of around 67%. This decline did not immediately trigger scarcity pricing but altered how forward risks are perceived within the market framework. Below the critical level of 55%, market participants began factoring in injection feasibility over winter adequacy when making pricing decisions.
A decline in liquidity on regional exchanges has also contributed to latent volatility within SEE markets. January trading volumes fell sharply—by 12.45% on SEEPEX and by 27.50% on CROPEX—leading to artificially calm price conditions during periods marked by upstream stress. Such thin trading environments can result in abrupt price spikes when congestion occurs or imports tighten.
Moreover, Europe’s increasing dependence on US liquefied natural gas (LNG) imports—projected at 57% for 2025 and potentially rising to between 75% and 80% by 2030—has shifted how price discovery occurs within the market. Reports regarding US LNG export issues have been observed to influence TTF movements even before confirmed data becomes available, underscoring the growing significance of perception over physical flow.
Italy continues to serve as a structural anchor for gas pricing within SEE markets, with a substantial share of its generation derived from natural gas (61.91%). This positioning allows Italy to maintain premium pricing during periods of stress while transmitting volatility laterally into neighboring countries like Croatia and Slovenia.
Conversely, Türkiye’s average electricity price of €57.42/MWh has established it as an outlier within the region due to regulatory protections and its unique fuel mix. While it sets a lower boundary for regional pricing structures, it does not provide any convergence signals among other SEE markets.
In conclusion, stakeholders operating within South-East Europe’s energy landscape must adapt their strategies to account for this evolving risk environment where various commodities are interconnected. The dynamics between gas prices, storage levels, LNG supply perceptions, and liquidity conditions will be instrumental in shaping future market developments across the region.
