New ETO Classes
ASX participants and users are advised that ASX will list 3 new Exchange Traded Option (ETO) Classes for trading on Monday 10 November 2025.
As is current policy the new ETO Classes will not have special size allocated initially.
The new ETO Classes will be reviewed every 3 months and those ETO Classes which meet ASX’s liquidity requirement will have Special Size crossing levels re-introduced. ETO crossings can still occur on the new ETO Classes but will need to be conducted on screen as opposed to a trade report whilst Special Size is not available.
Please refer to the table below for market making coverage in the new ETO Classes:

New ETO Classes will have maturities listed out 6 months to start and have a contract size of 100 shares. Flex option listings can occur on the new ETO Classes in line with ASX’s current policy and can be requested via tradingoperations@asx.com.au.
New Weekly Option Series
ASX will also make weekly option series available for 2 existing monthly ETO Classes from Monday 10 November 2025. The extension to ASX’s option offering is based on end user feedback and will be supported by 3 market makers; namely Susquehanna, Mako, and UBS.
Listing of the new weekly options will follow the current methodology. In general, they will expire on a Thursday and be listed out 3 weeks, providing there is not already a monthly expiry already listed.
The following Single Stock ETO Classes will have new weekly option series listed:
ASX Code |
Company Name |
GMG |
Goodman Group |
WHC |
Whitehaven Coal Ltd |
Margin parameters (PSR and VSR) of the new weekly options will follow those currently in place for the monthly style options.
Existing Weekly Option Series to be Delisted
ASX will cease automatic listing of new contracts for 2 existing weekly ETO Classes, halting the creation of new weekly expiries from Monday, 10 November 2025. These changes are being implemented due to a lack of trading activity in the weekly series and following consultation with market makers.
The following Weekly ETO Series are affected:
ASX Code |
Company Name |
LLC |
Lendlease Group |
TLS |
Telstra Group Ltd |
Note: Monthly ETOs for these ETO Classes will continue to exist.
Weekly contracts in LLC and TLS will have their final expiry on Thursday, 27 November 2025. Market makers will maintain coverage in series with open interest to ensure an orderly wind-down
What do I need to do by when?
Participants and end users should make the appropriate changes in readiness for the new ETO Classes and changes to existing weekly ETO Classes.
