Key takeaways
- CHESS is ASX infrastructure used for settlement and an electronic subregister that records broker-sponsored holdings.
- A CHESS-sponsored holder is identified by a Holder Identification Number (HIN), and ASX says securities on the CHESS subregister are held in the investor's own name.
- Issuer-sponsored holdings use a Securityholder Reference Number (SRN); custodial or omnibus arrangements can record ownership differently.
- CHESS sponsorship is a holding structure, not a recommendation or guarantee that a broker, share or investment is suitable or safe.
- ASX's CHESS replacement is underway: Release 1 clearing went live on 20 April 2026, while Release 2 covers settlement and subregister services.
If you buy Australian shares through a broker, you may see terms such as CHESS sponsored, HIN, issuer sponsored or custody. They describe how holdings are recorded and administered — not whether a particular investment is right for you.
CHESS stands for Clearing House Electronic Sub-register System. ASX uses CHESS to support settlement and an electronic subregister for broker-sponsored holdings. Understanding that distinction makes broker and platform information much easier to read.
CHESS in plain English
ASX describes CHESS as unusual because it combines settlement services with an electronic subregister. For eligible cash-market products, settlement transfers securities and payment between market participants. Separately, the CHESS subregister records broker-sponsored holdings.
The key idea
CHESS is not a broker, investment product or recommendation. It is infrastructure. A broker or other sponsoring participant manages the sponsored holder relationship, while the investor remains registered on the CHESS subregister for those holdings.
How CHESS fits into a share trade
When an ASX cash-market trade settles, CHESS is part of the process that exchanges payment for securities. ASX states that equity trades generally settle two business days after the trade date (T+2), using delivery versus payment so funds and securities move together through the settlement process.
Settlement and registration are related but different concepts. A useful way to think about CHESS is that it helps the market complete trades while also maintaining the CHESS subregister used by sponsored holders.
What does a HIN do?
Each sponsored holder on the CHESS subregister is identified by a Holder Identification Number (HIN). ASX says the HIN links the holding details maintained in CHESS with registration details such as the holder's name and address.
A HIN can cover multiple CHESS-sponsored holdings associated with that sponsored holder. It is not the same thing as a share, a bank account or an investment account balance. You can learn more in our plain-English HIN guide.
CHESS, issuer-sponsored and custody
These terms are easy to mix up. The important distinction is who is recorded as the legal holder and where that record is maintained.
| Structure | Typical identifier | What it means |
|---|---|---|
| CHESS sponsored | HIN | The investor is registered on the CHESS subregister for the holding. |
| Issuer sponsored | SRN | Legal title is registered on the issuer-sponsored subregister, generally administered for the issuer by its share registry. |
| Custodial / omnibus | Arrangement varies | A custodian or nominee may hold legal title while the client has a beneficial interest. The provider's terms explain the exact arrangement. |
ASX notes that investors can choose between CHESS and issuer-sponsored registration for eligible holdings. Moneysmart also warns that some lower-cost services use omnibus structures, so investors should read the terms to understand how holdings, voting and other corporate actions are handled.

Why the holding structure matters
Holding structure can affect administration, statements, transfers and how your ownership appears on the relevant register. ASX says CHESS-sponsored investors retain legal title to securities registered in their name and can consolidate sponsored holdings under a HIN. Issuer-sponsored holders instead receive an SRN for each issuer-sponsored holding.
That does not make “CHESS sponsored” a complete test of platform quality. Brokerage, FX costs, market access, service, account features, transfer fees and the provider's legal terms can also matter. Use our trading-platform comparison to research multiple factors rather than one label.
CHESS is being replaced
The infrastructure is changing. ASX's CHESS Project uses a staged approach: Release 1 for clearing went live on 20 April 2026. ASX says Release 2 covers settlement and subregister services and is progressing separately. Because that program continues to evolve, this page carries a visible review date and links to the current ASX project information below.
Questions to ask a trading platform
- For Australian shares, am I CHESS sponsored, issuer sponsored or using a custodial/omnibus structure?
- If CHESS sponsored, will I receive my own HIN?
- Who is the legal holder under the account structure?
- How are dividends, voting and other corporate actions handled?
- Can holdings be transferred, and are transfer or exit fees charged?
Verify the current answer in the provider's official terms rather than relying only on marketing language.
Frequently asked questions
What does CHESS stand for?
CHESS stands for Clearing House Electronic Sub-register System. ASX uses CHESS for settlement and for an electronic subregister that records broker-sponsored holdings.
What is a HIN?
A Holder Identification Number (HIN) identifies a sponsored holder on the CHESS subregister and links the holder's registration details with their CHESS holdings.
Is CHESS the same as a broker?
No. CHESS is market infrastructure. A sponsoring participant, commonly a broker or settlement participant, facilitates the CHESS-sponsored holder relationship.
What is the difference between a HIN and an SRN?
A HIN identifies a CHESS-sponsored holder. An SRN identifies an issuer-sponsored holding, and a separate SRN is generally used for each issuer-sponsored holding.
Is CHESS sponsorship always better than custody?
Not as a universal rule. The structures differ in legal title, administration and provider arrangements. Investors should understand the exact structure, fees, transfer process and terms rather than treating one label as a complete quality test.
