Market Participants are advised that ASX has formally lodged the Rules and Procedures with ASIC for the new deliverable Wallumbilla Natural Gas Futures Contract. Please refer to the Operating Rules and Procedures for details regarding the Rule Change. These Rules come into effect on trade date 19 August 2024, subject to final regulatory approval. The first contract month will be the October 2024 contract, with the first Futures delivery process to commence 24 September 2024 for gas to be delivered from 1 October 2024. Details of the delivery process can be found in the attached Wallumbilla Gas delivery guide.
The Wallumbilla Natural Gas Futures contract has been developed in conjunction with the Australian Energy Market Operator (AEMO) and is designed to support Australia’s east coast gas market by providing a transparent forward price curve out to 3 years. The contract will also help to improve liquidity in the Gas Supply Hub (GSH) and provide an additional hedging tool that allows gas market participants to efficiently manage their risk exposure.
