Trade-at-Index (TAI)
On 15 September, EEX will launch the Trade-at-Index (TAI) functionality for all its European gas markets. TAI brings flexibility and transparency to gas spot trading by allowing participants to execute trades during the day at a price determined later by the robust and well-established EEX indices. TAI simplifies trading by combining physical delivery with index-based pricing in one product. This provides traders with more flexibility in timing and reduces operational effort at the end of the trading day.
Trade-at-Index (TAI) supports the use of several eligible indices as reference prices for transaction execution.
At launch, the following indices will be available:
Specification for gas spot products traded under the Trade-at-Index functionality

Admission
At Go‑Live, all existing members active in EEX Natural Gas Spot trading will be admitted to the TAI instruments by default, provided that their clearing member has already confirmed their readiness to the TAI trading functionality.
Customers who do not wish to use the TAI trading functionality may opt out by contacting the membership@eex.com email address.
Trade Price
The payment information for Natural gas products traded via TAI is part of the existing payment report (EUR_1600 respectively GBP_1600) and will be provided at T+1 for financial settlement on T+2.
Trade Report
Members admitted to natural gas products traded via TAI receive the daily Trade Report for all trades across all asset classes at approximately 19.00 CET. This later delivery time is required to ensure that final prices, which become available at around 18.30 CET, are fully reflected in the report.
All other members (i.e. members not admitted to TAI products) receive their Trade Reports at approximately 17.00 CET as usual.
Advantages of Trading at Index
Transparent pricing
TAI ensures trades are settled against well-established EEX indices, such as End-of-Day (EOD), providing transparency and market confidence. TAI avoids execution risk and extreme prices when liquidity is low.
Enhanced hedging opportunities
Physical players can lock in exposure to index-based prices reducing execution risk and improving cost efficiency. Perfect for hedging floating index exposure and securing both physical delivery and commercial margin.
Operational Efficiency
TAI simplifies trading by combining physical delivery with index-based pricing in one product. This eliminates the complexity of bilateral arrangements and reduces operational stress at the end of the day, avoiding the volatility and pressure that typically occur near market close.
Liquidity and market development
By enabling trades linked to indices, TAI promotes a virtuous cycle: more trading on indices strengthens EEX benchmarks, which in turn drives adoption across retail, origination, and balancing markets.
Regulatory and Risk management alignment
Fully integrated into EEX clearing and reporting processes, ensuring compliance and robust risk controls without operational disruption.
