Australia’s overhaul of its beneficial ownership disclosure regime for listed entities is entering its final implementation phase – and the scale of the change is more consequential than the compliance paperwork suggests. On July 30, 2026, the Australian Securities and Investments Commission (ASIC) confirmed the final technical settings for a new regime that, from December 4, 2026, will require institutional investors to disclose equity derivative positions they were not previously required to report. For insurers, superannuation funds, and asset managers holding derivative exposure in ASX-listed companies, the compliance deadline is four months away.
The substantive shift is the introduction of a “deemed economic interest” concept. Australia’s substantial holding rules have not historically captured certain derivative-based economic exposures in listed entities, raising concerns that market participants could accumulate substantial economic interests or acquire stakes that confer significant influence without sufficient disclosure to other investors and the market.
Under the existing framework, cash-settled swaps, options, and other equity derivatives have not been included in the “5% plus” disclosure requirements. The Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act 2025, which received Royal Assent on December 4, 2025, expands substantial holding disclosure requirements to include derivative-based interests. The changes introduce the concept of a person’s “deemed economic interest” in an in-scope company, which takes account of what equity derivatives that person has acquired, even where those equity derivatives only provide an economic interest.
Not all industry participants accepted the change without qualification. In a January 2025 supplementary submission to Treasury, the Australian Financial Markets Association (AFMA) described the reforms as “complex in their implications and considered to be most significant,” warning they were likely to have “a significant negative impact on Australia’s equity derivatives market and the financial services industry and investors more generally.” AFMA argued that requiring the tracking and separate reporting of three subcategories of derivative-based holdings – including intra-derivative movements of 1% or more – would “introduce significant complexity without an informational (or other) benefit,” and risked generating “more noise into substantial shareholder reporting that is likely to make it more difficult to understand who actually beneficially owns or controls the voting shares of a listed company.”
ASIC proceeded with the regime following the consultation period, describing the final instrument as consistent with its regulatory simplification objective. The regulator’s July 30 announcement states that ASIC's responses to CP 387 feedback have been published on the consultation page, though that document had not been separately indexed at the time of publication.
This strengthening of Australia’s disclosure regime aligns with a wider global trend towards increased transparency in relation to derivatives. The EU’s Transparency Directive establishes transparency requirements with regard to the notification of the acquisition or disposal of major holdings, requiring shareholders to notify issuers when their holdings exceed or fall below certain thresholds, with issuers then disclosing those notifications to keep the public informed. The European Securities and Markets Authority (ESMA) has developed regulatory technical standards extending those requirements to financial instruments providing economic exposure to shares, including derivatives.
AFMA cautioned in its submission, however, that the proposed amendments “extend beyond FATF recommendations relating to beneficial ownership and beyond listed company disclosure requirements in other jurisdictions,” and called for a detailed comparative analysis before international consistency could be used as a policy justification. The association noted that comparable markets such as Hong Kong had granted statutory exemptions that Australia had not adopted, and that “the extra-territorial reach will impose an unreasonable burden” on internationally active market participants holding Australian-listed securities within global baskets or index products.
ASIC's July 30 announcement confirmed the operational details. The regulator consolidated Forms 603, 604, and 605 into a single Substantial Holding Notice (SHN), simplified the calculation method for deemed economic interests and offsetting short positions, and introduced an index-based format for registers of relevant interests (RORI). ASIC is also exploring with market operators a web-based submission portal for substantial holding information.
Updated regulatory guides have been published across Regulatory Guide 5, Regulatory Guide 9, and Regulatory Guide 222, with consequential amendments to five additional guides. Two new legislative instruments have been registered on the Federal Register of Legislation: ASIC Corporations (Listed Entities Enhanced Beneficial Ownership) Instrument 2026/482 and ASIC Corporations (Amendment and Repeal) Instrument 2026/483.
From December 2026, firms must monitor physical holdings, derivatives, and short positions together. The regime introduces three separate disclosure categories for derivative exposure, each requiring individual reporting, with updates triggered whenever any single category shifts by 1% or more – even if the aggregate position is unchanged. Anyone holding at least 5% under the expanded definitions when the law commences is deemed to hold that interest on commencement day, triggering an immediate disclosure obligation.
Compliance teams will need to familiarise themselves with the new form well before December 2026. A holder that does not acquire economic interests via derivatives may face difficulties navigating through this form on the first few occasions. The new regime does not change the existing rules around associates and aggregation – but it adds complexity. For corporate groups with entities entering into derivatives across different desks or jurisdictions, careful coordination will be required. The reforms also include increased penalties for existing offences under Chapter 6C of the Corporations Act 2001.
The listed entity reforms sit within a wider government push. The government allocated $207 million over 2025-26 to 2026-27 in the 2025-26 Budget to stabilise ASIC’s companies register, a prerequisite for integrating beneficial ownership data into national registration infrastructure. Policy development on a broader beneficial ownership register will continue through 2026, with stakeholder engagement and public consultation expected from early 2027. The reforms applying to unlisted entities will cover approximately 3 million regulated entities, including proprietary companies, unlisted public companies, managed investment schemes, and corporate collective investment vehicles – categories in which many insurance groups and financial services conglomerates operate.
