Southeast Europe has seen short-term electricity trading become more sophisticated, while the ability to transfer risk further along the curve remains uneven. Generators, suppliers and industrial consumers are facing more volatile merchant exposure and are seeking greater price certainty. The region’s spot market has also changed significantly.
Integration of spot trading across SEE markets
Romania, Bulgaria, Hungary, Croatia, Slovenia and Greece are increasingly integrated into broader European day-ahead and intraday structures. Quarter-hour pricing has improved market granularity, while market coupling is playing a growing role in cross-border flows. Serbia operates its own organised spot market and remains closely watched by regional trading desks.
When market participants move from short-term pricing to longer-dated risk management, the regional picture becomes less uniform. A generator asking for a lock-in price for next year encounters different liquidity and product availability than those focused on day-ahead or intraday outcomes. This mismatch affects how forward exposures can be managed across countries.
Forward hedging needs location, shape and timing
Long-term risk transfer is described as fragmented compared with improving short-term price discovery. Electricity businesses cannot operate solely on day-to-day trading, including renewable generators seeking to hedge next year’s output. Suppliers with fixed-price arrangements for industrial customers and industrial consumers needing budget certainty also rely on forward coverage.
EEX offers Hungarian, Romanian, Bulgarian, Serbian, Slovenian and Greek power futures across monthly, quarterly and annual maturities. The exchange also lists location-spread structures including Hungary-Serbia, Hungary-Romania, Hungary-Bulgaria, Hungary-Slovenia and Hungary-Greece. These contracts reflect that participants face both location risk and outright price risk.
Derivatives links with Hungarian physical markets
Hungary has taken steps to integrate derivatives with the physical market following the phase-out of HUDEX. In 2026, cooperation between HUPX and EEX enabled physical delivery of Hungarian power futures, strengthening the connection between the futures market and HUPX day-ahead activity. EEX also extended its Future-to-Spot mechanism to Hungary.
The Future-to-Spot extension allows eligible futures positions to feed corresponding bids into the HUPX day-ahead auction. The presence of products does not automatically translate into deep and reliable liquidity in forward markets. Liquidity depth remains a central challenge for Southeast European power trading.
Liquidity constraints and reliance on OTC structures
In Germany, participants can rely on a mature derivatives ecosystem with broad participation, established market makers and substantial clearing infrastructure. Many SEE products continue to operate in thinner markets, which can widen bid-ask spreads and make large transactions harder to execute. This can increase dependence on established OTC relationships.
Across much of Southeast Europe, bilateral EFET-style agreements remain essential infrastructure for forward trading. Counterparties can negotiate credit terms, delivery structures, volumes, profiles and locations that may not be efficiently available through listed products. The trade-off is greater dependence on counterparty relationships and credit capacity.
Proxy hedging leaves basis exposure
A structural issue highlighted in the region is proxy hedging when domestic forward liquidity is insufficient. A Serbian renewable generator unable to obtain sufficient liquidity in Serbian forward products may use HUPX as a proxy hedge. This reduces exposure to outright electricity price movements but leaves the Serbia-Hungary basis open.
If Serbian power settles €5/MWh above Hungary when the hedge is realised, physical revenue and the Hungarian hedge do not fully offset each other. Similar basis effects arise when participants use a more liquid neighbouring market to hedge less liquid domestic exposure. Proxy hedging therefore converts outright price risk into basis risk.
Renewables add capture-price and profile risks
The forward coverage challenge also includes contract shape limitations when hedging variable generation portfolios. A baseload future can hedge average electricity prices while offering limited protection against actual capture prices for solar or wind assets. As renewable penetration increases, generation can become concentrated in periods when wholesale prices are structurally lower.
A producer can therefore complete an annual baseload hedge successfully while still carrying substantial profile and capture-price risk. The forward market of the future is expected to address more than country coverage and maturity by pricing location, shape and timing. Trading houses are positioned to intermediate risks that standardised exchange products cannot always capture efficiently.
This includes renewable generation profiles, balancing exposure, cross-border basis and customised load shapes. The intermediation carries an economic value reflected as margin in trading activity. The region’s development path is described as likely moving toward a hybrid model combining listed markets with OTC handling of customised exposures where exchange liquidity is insufficient.
The key requirement is that forward liquidity becomes deep enough for electricity companies to manage long-term exposure without embedding excessive risk premiums into commercial decisions. Southeast Europe does not lack sophisticated spot markets but still lacks depth along the forward curve in many areas. Until that depth develops, managing long-term electricity risk depends not only on prices but also on relationships, collateral, credit capacity and balance-sheet strength.
