Family offices face a global regulatory tightening

The family office boom expanded under a relatively light-touch regulatory approach as governments competed for private capital, but that approach is now tightening as FATF evaluations, beneficial ownership reforms, adviser regulation, corporate-transparency rules and tax-reporting regimes converge on a sector whose growth has exceeded the supervisory frameworks originally designed to contain it.

The scale of the sector helps explain the policy shift. Deloitte estimates around 8,030 single family offices (SFOs) globally in 2024, up from 6,130 in 2019, managing approximately $3.1 trillion in assets on behalf of families with $5.5 trillion in combined wealth, although these remain modelled estimates rather than directly reported figures.

Family offices often sat outside full financial services licensing because they served a single family rather than external clients. While banks, trustees and advisers remained regulated, the office itself frequently operated in a lighter supervisory perimeter, leaving gaps in visibility over ownership, control and cross-border risk.

The perimeter is now closing, not through a single global reform but through parallel national and regional adjustments converging on similar outcomes: greater transparency, tighter reporting and more formal governance expectations.

Convergence under FATF pressure

The driver is not family offices alone. It is the wider pressure created by FATF's mutual evaluation process. FATF assesses financial centres against global anti-money laundering and counter-terrorism financing (AML/CTF) standards and publishes the results. Weaknesses in beneficial ownership transparency or supervisory effectiveness do not trigger sanctions, but they increase friction with counterparties and elevate perceived jurisdictional risk. Governments are therefore converging on transparency as a defensive measure rather than as part of a coordinated global programme.

This has produced alignment rather than uniformity. Jurisdictions are adopting different legal instruments but moving toward similar outcomes: clearer ownership identification, stronger reporting obligations and more visible control structures across legal entities and arrangements.

Global tightening across Europe, the US and offshore centres

Europe is moving through institutional AML/CTF reform. Regulation (EU) 2024/1620 established the Authority for Anti-Money Laundering and Countering the Financing of Terrorism (AMLA), which became operational on 1 July 2025 and introduced EU-level coordination with direct supervisory powers over selected high-risk entities.

Regulation (EU) 2024/1624, the AML Single Rulebook, will apply from 10 July 2027 and harmonise AML/CTF obligations across member states, including beneficial ownership rules. A key change is the shift from "more than 25%" to "25% or more" for ownership thresholds, bringing some structures previously just outside the scope into the reporting perimeter.

Directive (EU) 2024/1640 complements this framework by strengthening supervision, enforcement and transparency, with most provisions to be transposed by 10 July 2027. For family offices operating across Luxembourg, Ireland, the Netherlands, France, Germany and other EU centres, the direction is toward greater harmonisation and more consistent scrutiny of ownership structures.

The United Kingdom is moving through corporate registry reform. The Economic Crime and Corporate Transparency Act 2023 gives Companies House stronger powers to query, reject and remove information, introduces identity verification for directors and persons with significant control, and reforms corporate filing. Limited partnership reforms are being phased in, with implementation continuing through 2026 and beyond. For family office structures using UK companies, limited partnerships or overseas entities holding UK property, registries are becoming more active and interventionist. The shift is not family-office-specific, but it materially affects how such structures are documented and reviewed.

Australia's reform extends AML/CTF obligations to lawyers, accountants, real estate professionals and other designated service providers from 1 July 2026 under the Anti-Money Laundering and Counter-Terrorism Financing Amendment Act 2024. These advisers structure companies, trusts, property transactions and cross-border arrangements for private wealth. Australia is among the last major common law financial centres to bring these professional services within its AML/CTF perimeter, tightening oversight of intermediaries that sit between family offices and the financial system.

The United States follows a different trajectory. The Financial Crimes Enforcement Network (FinCEN) finalised a 2024 rule extending AML/CTF programme and suspicious activity reporting requirements to registered investment advisers and exempt reporting advisers, but implementation has been delayed, with current timelines pointing to 2028. Many SFOs remain outside Securities and Exchange Commission (SEC) investment adviser registration under the family office exemption, provided its conditions are met. The Corporate Transparency Act created a federal beneficial ownership reporting regime for many US companies, but the adviser perimeter remains a key gap. If implemented, the FinCEN rule would close one of the most significant remaining gaps in the global AML/CTF framework. Until then, the US position reflects delay rather than convergence.

From Geneva to George Town, the offshore perimeter narrows

The transparency push extends beyond major onshore financial centres. Switzerland's Act on the Transparency of Legal Persons and the Identification of Beneficial Owners, alongside revisions to the Anti-Money Laundering Act, will enter into force on 1 October 2026, introducing a federal beneficial ownership register and due diligence obligations for certain high-risk advisory activities. The Swiss Federal Council linked the reforms directly to FATF scrutiny, stating that "this timing will enable the Financial Action Task Force to assess the effectiveness of the new measures during its next evaluation of Switzerland, scheduled for 2027-2028." For Swiss holding companies, private investment structures and advisory relationships linked to family wealth, the reforms address ownership transparency rather than licensing.

Abu Dhabi Global Market (ADGM) refined its family office framework through enhancements enacted in September 2024, following a June 2024 consultation on its SFO and restricted-scope company regime, strengthening substance and governance while maintaining its positioning as a wealth hub.

The Cayman Islands are moving through tax transparency and crypto-asset reporting rather than classic SFO licensing. From 1 January 2026, Cayman implemented the Crypto-Asset Reporting Framework (CARF) and amended Common Reporting Standard (CRS) rules, expanding reporting obligations for financial institutions and in-scope crypto-asset entities, including some family-office fund vehicles. The offshore world was not transparency-free before these changes: the Foreign Account Tax Compliance Act (FATCA), CRS and beneficial ownership regimes were already in place. But the remaining space for low-transparency structuring continues to narrow.

From discretion to disclosure in Asia

Singapore is the clearest example of direct SFO reform. Its family-office sector grew from roughly 400 offices in 2020 to more than 2,000 by end-2024, supported by tax incentives and its position as Asia's leading wealth hub. That growth created a supervisory gap: in its 2026 mutual evaluation, FATF rated Singapore partially compliant on Recommendation 24 (beneficial ownership of legal persons) and Recommendation 25 (beneficial ownership of legal arrangements).

The revised Monetary Authority of Singapore (MAS) framework, effective 15 June 2026, is Singapore's answer. It introduces a class exemption from licensing under the Securities and Futures Act 2001 for qualifying SFOs, replacing the previous reliance on case-by-case regulatory relief. The simplification is real; so are the obligations. Qualifying SFOs must notify MAS within 14 days of commencing operations, maintain an account with a MAS-licensed bank and file annual returns covering assets under management (AUM) and banking relationships. Existing offices have a one-year transition period. The framework gives MAS systematic visibility over a rapidly scaled sector, with the annual return requirement creating a recurring reporting channel on size, banking links and risk profile for the first time. Singapore is not retreating from its family office strategy but formalising it: accepting higher reporting obligations in exchange for credibility, banking access and regulatory stability.

Hong Kong is taking a different approach. By end-2025, Hong Kong hosted more than 3,380 SFOs, an increase of about 680 offices over two years, equivalent to growth of more than 25%, according to a market study conducted by Deloitte and commissioned by InvestHK. Those offices employ more than 10,000 full-time professionals and contribute an estimated HKD 12.6 billion ($1.6 billion) annually to the local economy through operating expenditure.

Hong Kong operates a broader asset and wealth management ecosystem measured in the trillions, with approximately $4.5 trillion in assets under management as of end-2024, although this figure is not directly comparable to global SFO estimates and instead reflects the scale of the wider financial infrastructure supporting private wealth.

Rather than tighten the SFO perimeter in the same way as Singapore, Hong Kong is broadening its appeal. In February 2026, Christopher Hui, secretary for Financial Services and the Treasury, said the government planned "to introduce legislative proposals in the first half of this year to expand the scope of qualifying investment for the preferential tax regimes offered to funds and SFOs, covering, for example, precious metals, loans and private credit investments and digital assets." Alpha Lau, director-general of Investment Promotion at InvestHK, said that "single-family offices are not required to obtain a licence in Hong Kong in general, which helps maintain a high level of privacy. These are key considerations that overseas family offices particularly value."

AML/CTF and beneficial ownership rules still apply in Hong Kong through banks, trustees and regulated intermediaries. But at the SFO level, Hong Kong is not making the same trade-off as Singapore. Singapore is accepting more direct visibility in exchange for regulatory credibility; Hong Kong is defending privacy as a competitive differentiator. The question is which position ages better as FATF scrutiny deepens and as banks become more conservative about onboarding opaque structures.

Compliance becomes a competitive test

This regulatory wave is landing on a sector already in transition. The UBS Global Family Office Report 2026, drawing on a survey of 307 family offices across more than 30 markets, finds that 60% plan changes to strategic asset allocation over the next 12 months, driven by geopolitics, dollar exposure, interest-rate uncertainty, succession and liquidity needs. As capital moves across borders under pressure, family offices require clear ownership records, stable banking relationships and documented decision-making; the new frameworks make these structural necessities rather than optional governance choices.

The scale sharpens the stakes. Deloitte projects total SFO assets under management will rise 73%, from $3.1 trillion to $5.4 trillion, by 2030, with Asia Pacific among the fastest-growing regions. The sector is too large and too interconnected to remain lightly supervised.

For advisers and institutions, the shift is structural: Singapore adds recurring reporting touchpoints; the EU and UK tighten beneficial ownership and registry frameworks; Australia extends AML/CTF obligations to professional gatekeepers; Switzerland introduces federal beneficial ownership reporting; Cayman expands tax and crypto reporting obligations. The advantage will go to institutions that can map structures end-to-end. A family office spanning Singapore management, EU holding companies, UK property, Cayman vehicles, Swiss advisers and Australian professionals will face rules that interact rather than operate in isolation.

The sector grew faster than the transparency framework around it, and that gap is closing. Some families will still prioritise privacy, but access to banking, investment and advisory infrastructure will increasingly depend on structures that withstand regulatory scrutiny.
