For the first time in more than two centuries, Switzerland is no longer the world’s largest destination for offshore private wealth. The crown has passed east — by a margin thin enough to be uncomfortable.

According to BCG’s 2026 Global Wealth Report, Hong Kong ended 2025 with $2.95 trillion in cross-border assets under management, edging past Switzerland’s $2.94 trillion. The gap — roughly $10 billion in a $15.7 trillion global market — is barely a rounding error. But in wealth management, symbolism travels. What once seemed a forecast too bold to believe has landed, quietly, as fact.

The proximate causes are well understood: mainland Chinese capital seeking offshore diversification, a revived IPO market that minted a new cohort of ultra-high-net-worth founders, and a deliberate policy campaign by Hong Kong’s government to court family offices with tax concessions and residency pathways. The structural causes run deeper, and they tell a story about where global wealth is being created and where its owners want it held.

The Numbers Behind Hong Kong’s Ascent as an Offshore Wealth Hub

BCG’s annual wealth survey found that cross-border wealth globally grew 8.4% last year, reaching $15.7 trillion. That growth was heavily concentrated. Inflows moved overwhelmingly toward the world’s top ten booking centres, amplifying an already pronounced concentration of private capital in a handful of cities. Hong Kong was the primary beneficiary in Asia.

The city’s rise from $2.1 trillion in 2020 to $2.95 trillion today represents a compound annual growth rate of roughly 7% — strong, but not spectacular by the standards of a city whose boosters long promised an 8.5% trajectory. What made the difference in 2025 wasn’t just volume; it was composition. The IPO cycle turned sharply upward. Hong Kong ranked as the world’s leading IPO venue in 2025, raising over HK$274 billion by mid-December alone. Each listing created a new cohort of liquid, newly wealthy founders — and each founder needed a private banker.

Alongside this, mainland Chinese insurance premiums purchased in Hong Kong hit HKD 62.8 billion in 2024, an eight-year high and a 6.5% year-on-year increase. Insurance-linked wealth structures are a significant entry point for Chinese nationals moving capital offshore — technically compliant, politically legible, and increasingly popular.

Then there are the family offices. By the end of 2025, Hong Kong hosted 3,384 single-family offices, a 25% increase in just two years, according to a Deloitte survey commissioned by the Hong Kong government. Of those, 1,095 managed assets of $100 million or more. That’s not a startup ecosystem; it’s an institutional wealth infrastructure.

The government of Chief Executive John Lee, who first set a target of 200 new family offices in his 2022 Policy Address, has since watched that figure be exceeded by an order of magnitude. The New Capital Investment Entrant Scheme, launched in March 2024, offers residency to investors allocating HKD 27 million to qualifying assets — a number calibrated precisely to attract the mainland’s upper-middle-wealthy rather than only the ultra-rich.

Why Hong Kong Overtook Switzerland — and Why It Matters for Global Wealth Flows

The straightforward answer: China. The more accurate answer: China’s property crisis, China’s capital controls, and China’s growing class of entrepreneurs who cannot conveniently keep their wealth in renminbi.

“Hong Kong is cementing its role as China’s gateway to global markets,” BCG wrote in its 2026 report, “though that same concentration ties its trajectory tightly to economic and regulatory developments on the mainland.” It’s a candid acknowledgement of a structural dependency that rivals would call a vulnerability and Hong Kong’s bankers would call an enduring competitive moat.

Why did Hong Kong overtake Switzerland as the world’s top cross-border wealth hub? Hong Kong’s rise is driven primarily by capital from mainland China seeking offshore diversification, a 2025 IPO boom that created a wave of new high-net-worth clients, and an aggressive government push to attract family offices through tax concessions and residency incentives — all against a backdrop of 9% projected annual growth through 2030.

That growth forecast matters. BCG projects both Hong Kong and Singapore will expand their cross-border wealth bases at roughly 9% annually through 2030. Switzerland is expected to grow at 6%. Over a decade, compounding turns a marginal lead into a structural dominance.

Yet the more consequential observation from the BCG data is what it implies about the architecture of global wealth management. Michael Kahlich, who co-authored the BCG report, put it plainly: “What ultimately matters is client proximity.” Two distinct regional poles are forming — Singapore and Hong Kong for Asia, Switzerland alongside the UK and the US for the Western world. The era of a single, neutral global safe haven, anchored in Alpine discretion, is giving way to a multipolar geography of private capital.

Switzerland spent two centuries accumulating that position. Its displacement — even partial, even narrow — represents a genuine inflection point. Jason Fong, a 27-year banking veteran tasked by the Hong Kong government with attracting family offices, was blunter about it in 2024: “They are crumbling and we are in a very advantageous situation.”

What the Shift Means for Banks, Markets, and the Architecture of Private Capital

The implications extend well beyond the wealth management industry itself.

For banks, the geography of client assets is the geography of revenue. HSBC, which contributed 54% of its group wealth and personal banking international revenue from Hong Kong in the first half of 2024, stands to gain disproportionately from the city’s continued rise. Standard Chartered, DBS, and Bank of China (Hong Kong) are positioned similarly. By contrast, UBS — which absorbed Credit Suisse and simultaneously retreated from parts of its Asian business — may find that its Switzerland-anchored model is progressively less suited to the clientele driving growth. That $10 billion gap between Hong Kong and Switzerland today could be $100 billion by 2028.

For policymakers, the shift raises questions that wealth managers prefer not to discuss in client-facing materials. Bloomberg Intelligence’s Hong Kong Wealth Management 2026 Outlook projects that China’s household assets will grow at 9.3% annually, with overseas investment rising from 8% to 11% of investable assets by 2030. That capital is predominantly routing through Hong Kong. It’s a dynamic that suits Beijing — the city provides offshore diversification for Chinese nationals while remaining within a jurisdiction that the mainland government controls at the constitutional level. For international policymakers worried about capital flight from China, or about financial stability in Hong Kong, the numbers represent both a success story and a risk concentration.

For businesses deciding where to book their treasury or establish their family office, the practical calculus has shifted. Hong Kong’s territorial tax system — no capital gains tax, no inheritance tax, no offshore income tax — remains structurally competitive. The Cross-Boundary Wealth Management Connect scheme, which now counts more than 160,000 investors, has created a bidirectional capital channel between Hong Kong and the Greater Bay Area that no other jurisdiction can replicate.

Still, the composition of Hong Kong’s inflows carries a concentration risk that Switzerland’s book does not. Switzerland’s appeal is precisely its diversification across source jurisdictions — Middle Eastern royalty, Latin American industrialists, European entrepreneurs, all in one account ledger. Hong Kong’s growth engine is, at its core, one large economy’s wealthy class seeking one particular form of offshore access. That’s a formidable engine. It’s also a single point of failure.

The Case for Switzerland — and the Limits of the Hong Kong Thesis

Credit where it is due: Switzerland is not losing clients. It’s gaining them, just more slowly.

“Geopolitical uncertainty reaffirms Switzerland’s role as a core global booking centre,” BCG noted in the same report that documented Hong Kong’s overtaking of it, “attracting flight-to-safety flows from more volatile regions such as the Middle East.” Wealthy individuals from the Gulf states, rattled by regional conflict and wary of the political exposure that comes with Gulf residency, have been moving assets to Switzerland with renewed urgency. That inflow is real, even if it’s smaller than what Hong Kong is absorbing from China.

There’s also the rule-of-law argument, and it’s not trivial. Hong Kong’s 2020 National Security Law fundamentally altered the city’s legal landscape. For wealth held across generations, the durability of legal protections matters as much as the tax rate. The Swiss legal system’s neutrality, its centuries of consistent enforcement, and its structural independence from any major geopolitical bloc represent attributes that cannot be replicated in Hong Kong under its current constitutional arrangement with Beijing.

The Swiss Bankers Association has identified compliance with international sanctions regimes as the leading geopolitical risk facing Swiss wealth managers — a concern prompted largely by Western sanctions on Russia. But the inverse concern applies to Hong Kong: wealth held there is subject to the risk that US or EU sanctions could eventually target mainland-linked entities operating through Hong Kong, given the territory’s eroding autonomy. That risk has not materialised in a way that disrupted the 2025 data. But sophisticated wealth owners holding multi-decade horizons are watching it.

Singapore offers a third path. Positioned between Hong Kong’s China-proximity and Switzerland’s Western neutrality, the city-state continues to grow at 9% annually — roughly matching Hong Kong’s trajectory but with a more diversified client base and a governance track record that generates less geopolitical anxiety. It’s the quiet competitor that neither Zurich nor Hong Kong fully accounts for.

A New Axis of Private Wealth

The $10 billion difference between Hong Kong’s $2.95 trillion and Switzerland’s $2.94 trillion is, in isolation, nearly meaningless. What it marks is a direction of travel that has been underway for years and is now officially confirmed.

Global wealth is growing fastest in Asia — and that wealth wants to be managed close to where it was created, by institutions that understand the tax codes, the family structures, and the political sensitivities of Chinese entrepreneurs. Hong Kong, for all its complications, remains the only city on earth that offers simultaneous access to mainland China’s capital markets and the infrastructure of an international financial centre. That combination is not easily replicated.

Switzerland retains what no Asian city yet possesses: centuries of demonstrated political neutrality, the institutional credibility of a jurisdiction that has outlasted empires, and a client base diversified enough to weather any single country’s economic cycle. The Swiss franc’s role as a safe-haven currency is a structural asset that the Hong Kong dollar — pegged to the US dollar and ultimately backstopped by Beijing — cannot claim.

The picture is more complicated than any single ranking conveys. What BCG’s 2026 data has confirmed is that the world’s private wealth now answers to two distinct centres of gravity. The question of which will be larger in a decade is less interesting than the question of what it means that the answer is no longer obvious.

Two centuries of Swiss dominance ended, quietly, sometime in 2025 — with barely $10 billion separating a former colony from the Alps.
