A November 2026 first-week TTF natural gas weekend futures contract is listed under the identifier G3W1X2026, linking a short-term Dutch gas-market derivative to the European Gas Spot Index. The product is financially settled, so it is designed for exposure to gas prices without physical delivery. The available contract information identifies the maturity and benchmark structure but does not establish an executed trade, price, trading volume or open interest for this specific contract.
The contract sits within a broader EEX range of financially settled gas futures covering the Dutch TTF, German THE, British NBP and Austrian CEGH market areas. Those products include daily, weekend, weekly and longer maturities such as month, quarter, season and calendar year contracts.
EGSI is calculated from qualifying trades in day-ahead and weekend contracts executed between 8 a. The calculation is based on a volume-weighted average of eligible transactions, while the Weekend EGSI is calculated as the arithmetic mean of the Day EGSI values for the Saturday and Sunday delivery days in the relevant calendar weekend. That distinction means the benchmark is a mathematical reference derived from underlying market activity rather than an exchange price for the futures contract itself.
EEX’s published methodology also separates EGSI from other gas references, including the Next Day Index, the End of Day price, the Within-Day Reference Price and the EEX530 order-book index. The exchange says indices are calculated under documented, rule-based methodologies and that indices used as references for financial instruments qualify as benchmarks under the European Union’s Benchmark Regulation. Final settlement prices for derivatives are governed separately by contract specifications and settlement procedures.
The November weekend future is also distinct from a separate EEX product expansion announced for Nov. That initiative covers physically settled Natural Gas Daily Futures for TTF, THE, CEGH VTP and PEG, with daily maturity granularity and a Day-Month spread function. The announcement places those contracts alongside, rather than inside, the existing financially settled EGSI futures framework, leaving G3W1X2026 as a benchmark-linked financial instrument rather than a newly announced physical-delivery contract.
