How high net worth is defined: Singapore's Accredited Investor test and industry wealth tiers

There is no single legal definition of a "high-net-worth individual" (HNWI) in Singapore. The benchmark used most often in law, and the one with real consequences, is the Accredited Investor (AI) definition in section 4A of the Securities and Futures Act 2001 (SFA). The "millionaires" and "ultra-high-net-worth" categories quoted in the media and industry reports come from research by firms such as Capgemini and UBS. The difference is that the first determines what financial institutions may offer you and which protections you give up, while the second is simply a way of segmenting populations for statistics and market research.

The legal benchmark: three Accredited Investor tests

Under SFA section 4A(1)(a)(i), an individual meets the financial threshold for Accredited Investor status by satisfying any one of the following (subject to the current text of SFA section 4A, and to an express opt-in with the institution):

Some background is worth knowing. First, in its written parliamentary reply of 5 February 2025, MAS stated that the AI eligibility criteria were last updated in 2018 and that it keeps investor classifications under review. Second, all three thresholds are set in Singapore dollars, so foreign-currency assets must be converted at the rate the institution uses; exchange-rate movements can mean the same family qualifies one year and not the next. Third, "net" means liabilities are deducted: for families who borrow against property or an investment portfolio, gross assets and net assets can differ considerably.

Opting in: what becoming an AI means

Meeting a threshold only makes you eligible; it does not mean you are automatically treated as an AI. Under MAS's opt-in regulations, in force since 8 January 2019, an eligible investor must "expressly opt in" before a financial institution may treat them as an AI. Opt-ins with different institutions are independent of each other, and the way to withdraw follows the MAS FAQs and each institution's documents.

MAS's page on collective investment schemes explains that restricted schemes, offered only to relevant persons or in amounts of not less than S$200,000 per transaction, can be exempt from authorisation, recognition and prospectus requirements (MAS, page updated 5 October 2026). An AI can therefore see more products, but those products come with less disclosure and often lower liquidity. The question to ask before opting in is "Do I need these products, and do I understand their risks?", not whether AI status is a mark of standing.

Thresholds for companies and other entities

Family investment companies, single family office entities and trusts may also open accounts as investors. The MAS FAQs state that the threshold for a corporation to be an AI is net assets exceeding S$10 million (the "$10 million net assets threshold"). Trustees, entities wholly owned by AIs and other cases are covered by separate provisions; these need to be checked against the current text of SFA section 4A and assessed by a lawyer or the institution's compliance team.

In HNW planning, several other public thresholds are often used as reference points for scale. They belong to different regimes and cannot substitute for one another; they are listed together only to show which regulatory gateway corresponds to which level:

The full 13O/13U conditions (designated investment size, number of investment professionals, local business spending, capital deployment and so on) are covered on the sister site vccfund.sg. GIP criteria and procedures follow EDB's latest documents, and approval is a matter for the authorities.

Industry conventions: millionaires, mid-tier and ultra-high-net-worth

Industry reports segment by investable assets rather than net worth. The common conventions are as follows (industry research conventions with no legal effect):

• Capgemini, World Wealth Report: an HNWI is an individual with investable assets of US$1 million or more, excluding the primary residence, collectibles, consumables and consumer durables. The group is split into "Millionaires Next Door" (US$1–5m), "Mid-Tier Millionaires" (US$5–30m) and "Ultra-HNWIs" (above US$30m).
• UBS, Global Wealth Report: people with wealth between US$1 million and US$5 million are described as "everyday millionaires".

The 2026 editions of both reports give the latest figures (all historical, not indicative of future results):

The UBS 2026 press release does not give the number of US-dollar millionaires in Singapore; the figures circulating online mostly come from earlier editions or second-hand reports, and this site does not cite them. More market data is in Singapore wealth management market data.

How the two benchmarks differ

The most common confusion is to treat "meeting the AI threshold" and "being a US-dollar-millionaire HNWI" as the same thing. A professional with one home, modest cash and an income of S$300,000 may meet the AI income test while being far short of US$1 million in investable assets. Conversely, a retiree with ample investable assets may have no income but still qualify on net financial assets.

Tiers and the services they open up

A wealth tier affects which services and regulatory gateways are available, not what you should buy. The following is a general description; actual thresholds are set by each institution and its latest documents prevail:

How the tools divide the work is explained in Singapore's wealth tools landscape. Readers who need a plan designed around their family can refer to the private banking and family office practice areas on the sister site hnwsolution.sg.

Common misconceptions

1. "Becoming an AI gives access to higher-return products." AI status only widens the range of products available. Those products often come with less disclosure and lower liquidity, and no return is promised.
2. "Meeting the threshold makes me an AI automatically." You must expressly opt in with each institution; until you do, the institution continues to treat you as a retail investor.
3. "AIs do not need a suitability assessment." MAS has made clear that institutions must assess whether a product is suitable for a client, whether or not the client is an AI.
4. "High net worth on paper makes me an HNW client." Institutions look at verifiable net personal assets, net financial assets or income, and at source-of-funds and source-of-wealth documents. Families whose wealth is concentrated in private company shares or a single property may run into documentation and valuation issues at account opening.
5. "Industry tiers can be used as a legal basis." The Capgemini and UBS tiers are for research only and have nothing to do with regulatory treatment.
6. "Once I qualify, I qualify for good." Exchange rates, asset prices and changes in liabilities all affect whether you continue to meet the threshold, and institutions review this periodically under their own procedures.
