From December 4, 2026, an investor holding a cash-settled swap over an ASX-listed company must file a public substantial holding notice once the position reaches 5% of a class, while the bank that wrote and hedged that swap discloses nothing until its suppressed exposure crosses 20% — and even then it files a statement to the market operator, not a substantial holding notice.

That asymmetry is written into the ASIC Corporations (Listed Entities Enhanced Beneficial Ownership) Instrument 2026/482, made on July 27, 2026 by Amanda Zeller as delegate of the Australian Securities and Investments Commission (ASIC) and registered as F2026L00995 on July 29, 2026. Section 9 counts a deemed economic interest at the full notional amount of the underlying securities. Sections 16 to 18 then remove that interest entirely from licensees dealing for clients, making markets or clearing. This analysis walks the operative sections, tests ASIC’s equivalence declaration against what the US regulator actually did, and sets out what compliance teams must build before the transition closes.

Key facts

• Commencement: the later of the day after registration and the commencement of Schedule 1 to the Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act 2025 (section 2) — which ASIC confirms is December 4, 2026 (Regulatory Guide 222, July 30, 2026).
• Counting method: full notional amount of underlying securities, not delta-adjusted (sections 9 and 12).
• Basket carve-out: the interest is zero only where the exposure is both under 5% of the class on issue and under 30% by value of the basket (sections 10(3) and 13(3)).
• Eight index providers named in the text: S&P Dow Jones Indices LLC, MSCI Inc, FTSE International Limited, NASDAQ, Inc, Morningstar, Inc, Solactive AG, Bloomberg Index Services Limited and STOXX Ltd (sections 10(4), 13(4)).
• Dealer trigger: 20% of holding percentage recalculated as if sections 16 and 17 did not apply, then every move of 1 percentage point or more above it (section 19(2)), filed within 2 business days (section 19(4)).
• Transition: transitional Forms 603, 604 and 605 run from December 4, 2026 to June 3, 2027; from June 4, 2027 only the new Substantial Holding Notice is accepted (RG 222.8, RG 222.179–180).
• Sunset: the instrument is repealed at the start of October 1, 2031 (section 31).

Methodology and sources

This analysis is built from primary documents. The operative text is the 24-page instrument as registered, read alongside the 20-page Explanatory Statement and the registered instrument itself. Section references are to the instrument unless stated. The guidance layer comes from ASIC’s Regulatory Guide 222 and the Summary of feedback to Consultation Paper 387, both published July 30, 2026. The comparison jurisdictions are the three ASIC itself declares equivalent in section 30, tested against the Financial Conduct Authority (FCA) Handbook and the US Securities and Exchange Commission (SEC) adopting release. Consultation ran from March 10 to April 21, 2026 and produced 23 submissions, six of them confidential. Nothing here is modelled; every number is drawn from a named document.

What the rule actually says about counting a swap

A deemed economic interest is the concept Schedule 1 inserted into Chapter 6C of the Corporations Act 2001. It attaches to the long side of a non-physically settleable derivative — in practice a cash-settled total return swap, contract for difference or option — over securities in a “Chapter 6C body”. The instrument’s job was to say how many securities that interest represents. Section 9 answers plainly: the number “is equal to the full notional amount of securities of that class underlying the derivative”. Section 12 applies the same rule to offsetting short positions. There is no delta, no pricing model and no daily revaluation. A deep out-of-the-money call over 6% of a company counts as 6%, and it aggregates with physical holdings and associates’ positions into the 5% substantial holding threshold that has governed Australian markets for decades.

That was not the design Parliament expected. The Explanatory Statement records at paragraph 8 that the Explanatory Memorandum to the enabling Bill “expressed an expectation that any legislative instrument ASIC makes be tailored around a similar approach to that in Article 5 of the Commission Delegated Regulation (European Union (EU)) 205/761 of 17 December 2014” — meaning delta-adjusted calculation using a generally accepted pricing model. ASIC consulted on exactly that in Consultation Paper 387 and, in its own words, “feedback was critical”. Respondents said delta produced no single correct answer because it depended on inputs that varied between participants. ASIC changed course, citing its obligation under section 1(2) of the ASIC Act to strive to reduce business costs, and settled on full notional.

The trade-off shows in the basket rules. Section 10(3) zeroes an index-derived interest only where both limbs are met: under 5% of the class on issue and under 30% by value of the basket. Industry asked for the second limb to be lifted from the draft’s 20%, and ASIC agreed, explaining that “while a 20% threshold accords with the UK, we recognise that Australia’s market is more concentrated by global standards”. Section 10(4) zeroes it outright where the index is compiled by one of eight named providers under a published methodology, or where an exchange traded fund tracks the basket — both switched off for a bidder in a bid period (section 10(5)) and where the holder can influence the basket’s composition (section 10(6)).

How four regimes count the same swap

Jurisdiction / instrument	Effective date	Initial threshold	Cash-settled derivative treatment	Filing deadline
Australia — ASIC Instrument 2026/482	December 4, 2026 (s 2; RG 222)	5%; dealers at 20% (s 19(2))	Full notional amount (ss 9, 12); zero for baskets only on the dual 5%/30% test (s 10(3))	2 business days, or 9.30 am next trading day in a bid period (s 19(4))
UK — FCA Handbook DTR 5	In force; declared equivalent by s 30(b)	3%, then each 1% for UK issuers; 5, 10, 15, 20, 25, 30, 50, 75% for non-UK issuers (DTR 5.1.2R)	Notional shares multiplied by delta where exclusively cash-settled (DTR 5.3.3AR)	Notify the issuer within 2 trading days, 4 for non-UK issuers (DTR 5.8.3R)
US — Exchange Act ss 13(d), 13(g)	Amendments effective February 5, 2024 (Release Nos. 33-11253; 34-98704)	More than 5% of a covered class	Not deemed at all. Proposed Rule 13d-3(e) was not adopted; left to guidance under existing Rule 13d-3	Initial Schedule 13D within 5 business days; amendments within 2
New Zealand — FMCA 2013, Subpart 5 of Part 5	In force; declared equivalent by s 30(a)	Substantial product holder disclosure under Subpart 5 of Part 5	Relief rather than a counting rule: a person subject to the NZ requirements is relieved of Part 6C.1 (s 671F(2))	Conditional — the entity must pass the information to each Australian market operator as soon as practicable (s 671F(3))

The US column is where the equivalence declaration strains. Section 30(c) declares “the requirements of subsections (d) and (g) of section 13 of the Securities Exchange Act 1934 of the United States of America” equivalent to Australia’s Part 6C.1. Yet in the October 10, 2023 adopting release the SEC wrote: “We are not adopting proposed paragraph (e) to Rule 13d-3 to deem certain holders of cash-settled derivative securities as beneficial owners of the reference covered class. Consistent with the views expressed by several commenters, we have determined that Commission guidance on the applicability of existing Rule 13d-3 to cash-settled derivative securities … would provide sufficient clarity.” Proposed Rule 13d-3(e) would have deemed a holder a beneficial owner where the derivative was held with the purpose or effect of changing or influencing control. It died. ASIC has therefore declared equivalent a regime that expressly declined to codify the deeming Australia is now importing at full notional — while assessing Canada, South Africa and Hong Kong and finding them not sufficiently equivalent. The UK sits in between: DTR 5 captures cash-settled instruments, but at delta, the method ASIC abandoned.

“Today’s adoption updates rules that first went into effect more than 50 years ago. Frankly, these deadlines from half a century ago feel antiquated. In our fast-paced markets, it shouldn’t take 10 days for the public to learn about an attempt to change or influence control of a public company.”

— Gary Gensler, then Chair, US Securities and Exchange Commission (SEC press release 2023-219, October 10, 2023)

Where the dealer exclusion actually bites

Sections 16 to 18 are conditional, not automatic. Section 16 removes the deemed economic interest from an Australian financial services licensee or a “foreign equivalent licensee” dealing in the ordinary course of its derivatives business to facilitate or hedge client exposure — but only where the client provides the consideration (s 16(c)), the dealing “does not have, and is not reasonably capable of having” any capacity to influence the issuer’s affairs (s 16(d)), and the licensee “is able to readily identify derivatives to which this section applies” (s 16(e)). Section 17 mirrors this for market makers, section 18 for clearing and settlement facilities, and notional section 671AY(4), inserted by section 21, extends the same treatment to offsetting short positions. Section 15 defines a foreign equivalent licensee as an entity incorporated and principally located offshore, licensed abroad to deal, make markets or operate a clearing facility, and which “does not hold, and is not required to hold” an Australian financial services licence.

What replaces disclosure is narrow. Under section 19(2) a licensee relying on section 16 or 17 must notify each relevant market operator — the exchange, not ASIC — when its holding percentage, recalculated as if those sections did not apply, moves above 20% or down to 20% or below, or shifts by a percentage point or more while above 20%. Note what the notice contains: section 19(3)(f) requires “the increase in each of the following percentages that would result if sections 16 and 17 … did not apply”, and the statutory Note works the example — a licensee at 8% that would be at 10% discloses an increase of 2%. The operator learns the size of the suppression, not the position. Section 18 clearing exposures carry no section 19 trigger at all. And the physical hedge is untouched: shares held against a client swap still create an ordinary relevant interest, which is why RG 222.45 requires an exempt licensee filing a notice for uncovered securities to acknowledge its reliance at item 12 of the Substantial Holding Notice.

Enforcement context: what non-disclosure has cost before

Australia already treats opaque substantial holdings as a market-integrity failure rather than a paperwork lapse. In Tribune Resources Ltd [2018] ATP 18, a Takeovers Panel sitting of Christian Johnston (sitting President), Chelsey Drake and Teresa Dyson made a declaration of unacceptable circumstances on September 14, 2018 over the ownership of roughly 60% of an ASX-listed gold producer. The Panel found the market had not been informed “to a very significant degree, and over a lengthy period” about who held substantial interests; ASIC submitted the parties had failed to correct their disclosures even after receiving tracing notices. The orders went beyond corrective disclosure to vesting Tribune shares held by an associated listed entity in ASIC.

The Panel has policed derivatives directly too. Guidance Note 20: Equity Derivatives, first issued April 11, 2008 and reissued October 4, 2021, expects disclosure where a long position reaches 5% and then changes by at least 1%, and warns that a long position above 20% may itself give rise to unacceptable circumstances. The statutory consequences are now sharper. RG 222.24 confirms that failure to comply is an offence carrying compensation liability under sections 671B(4)–(5) and 671C; RG 222.171 records ASIC’s freezing-order powers under sections 673A and 673B, with divestiture available under section 1325A. RG 222.175 adds a detail dealers should read closely: where a freezing order relates to derivative-based interests, ASIC says it may prefer an order targeting the derivative rather than freezing an arm’s-length counterparty’s hedge. ASIC also refused to soften the landing, telling respondents it would not adopt “a no-action position or a facilitative compliance approach”.

What this means for dealers, funds and compliance teams

Sell-side dealers and market makers. The exclusion is only as good as the tagging. Sections 16(e), 17(c) and 18(c) require the firm to readily identify qualifying derivatives, which means flagging carve-out status at booking rather than reconstructing it at quarter-end. Section 19 then forces a permanent shadow calculation: the firm must know at all times what its holding percentage would be without sections 16 and 17, because that shadow number drives the 20% trigger and every subsequent one-point move.

Buy-side holders of synthetic exposure. Hedge funds, superannuation funds, insurers and activist vehicles now aggregate cash-settled exposure at full notional into a 5% test. Firms that sized synthetic positions on delta will see their reportable percentage jump without a single new trade. Section 28(e) then requires a first notice to itemise every transaction that created or changed a relevant interest, deemed economic interest or offsetting short position in the four months before the obligation arose — reconstructible from trade records, not position snapshots.

Legal and documentation teams. Section 29 lets four standard agreements be named rather than attached, provided differences are identified: the ISDA Master Agreement including its Schedule, the FIA-ISDA Cleared Derivatives Execution Agreement, the FBF Master Agreement and the DRV German Master Agreement. Registers of relevant interests must be electronic and delimited from December 4, 2026 (sections 24 and 26), with copies supplied in the same format (section 25). The perimeter question echoes the one this desk mapped in prop-firm regulation across the CFTC, FINRA and MiFID: eligibility turns on activity, not entity type, and ASIC declined to extend it to investment managers, superannuation trustees or proprietary trading firms.

“Careful calibration is needed to ensure that economic exposure, of itself, is not treated as indicative of control or influence, and that the regime avoids high-volume, low-value disclosure that obscures economically meaningful signals.”

— Australian Financial Markets Association, submission to CP 387, April 21, 2026 (published submission)

What’s next: the June 2027 cliff and the five-year clock

The binding deadline is not December. It is June 4, 2027. ASIC refused to defer commencement — it told respondents it does not have that power — but conceded a six-month window in which substantial holders may use transitional Forms 603, 604 and 605, provided derivative interests appear in an annexure setting out the derivative-based, deemed physically settleable, deemed non-physically settleable and offsetting short position percentages (RG 222.181). From June 4, 2027 those forms stop working, with no fallback.

Two threads stay open. ASIC expressly reserved powers it did not exercise — section 672AD(2) on tracing-notice particulars and section 672DA(4) on register exemptions — so it can respond to observed practice. And the instrument repeals itself at the start of October 1, 2031, a five-year clock that guarantees a remake consultation, and with it a second run at the delta question and the equivalence list. Whether a US regime that declined to deem cash-settled holders beneficial owners stays on that list is the live argument. ASIC’s broader posture leaves little doubt about direction: its record enforcement year, covered in this analysis of what an FX licence buys after ASIC’s A$830m year, and the divergence traced in its A$300m CFD penalty, point the same way. So does the transparency push visible in the UK, where the FCA found three quarters of retail share trades are off-tick and is reshaping derivatives transaction reporting by 2028.

FAQ

When does ASIC Instrument 2026/482 take effect?

Section 2 sets commencement as the later of the day after registration (July 29, 2026) and the commencement of Schedule 1 to the Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act 2025. ASIC confirms in Regulatory Guides 222 and 5, both issued July 30, 2026, that Schedule 1 commences on December 4, 2026. The register and copy-request duties in sections 24 and 25 apply only to disclosures made on or after that date.

Do banks writing client swaps have to disclose anything?

Not in a substantial holding notice, for the carved-out derivatives. Sections 16 to 18 remove the deemed economic interest for licensees dealing for clients, making markets or clearing, and notional section 671AY(4) does the same for offsetting short positions. Section 19 substitutes a statement to the relevant market operator, triggered only when the holding percentage calculated as if sections 16 and 17 did not apply moves above 20% or to 20% or below, or shifts by one percentage point or more above 20%. Physical hedge shares still create an ordinary relevant interest.

Which foreign regimes did ASIC declare equivalent?

Three. Section 30 declares Subpart 5 of Part 5 of New Zealand’s Financial Markets Conduct Act 2013, DTR 5 of the FCA Handbook’s Disclosure Guidance and Transparency Rules sourcebook, and subsections (d) and (g) of section 13 of the US Securities Exchange Act 1934. ASIC assessed Canada, South Africa and Hong Kong and found them not sufficiently equivalent. The relief is conditional: under section 671F(3) the listed entity must give the foreign-filed information to each Australian market operator as soon as practicable.

Which indices escape the deeming rule?

Section 10(4) zeroes a basket- or index-derived deemed economic interest where the index is compiled and calculated by one of eight named providers — S&P Dow Jones Indices LLC, MSCI Inc, FTSE International Limited, NASDAQ, Inc, Morningstar, Inc, Solactive AG, Bloomberg Index Services Limited or STOXX Ltd — under a publicly available methodology with quoted constituents, or where at least one exchange traded fund tracks the basket. Neither route applies to a bidder during a bid period, or where the holder can influence the basket’s composition.

What happens to Forms 603, 604 and 605?

They survive as transitional forms only. RG 222.180 permits substantial holders to use transitional Forms 603, 604 and 605 from December 4, 2026 to June 3, 2027, provided any deemed economic interest or offsetting short position appears in an annexure. RG 222.8 states that from June 4, 2027 substantial holding information may only be disclosed in the new consolidated Substantial Holding Notice, whose particulars are set by section 28 and the forms approved in ASIC Instrument 2026/595.

What are the consequences of getting it wrong?

RG 222.24 confirms that failing to comply is an offence and may create liability to compensate persons for loss under sections 671B(4)–(5) and 671C, with a limited defence in section 671C(3). ASIC may also make freezing orders under sections 673A and 673B and seek divestiture under section 1325A. It declined industry requests for a no-action position, and RG 222.175 signals it may target the derivative interest itself rather than a counterparty’s hedge.
