Hong Kong has once again ranked third in the Global Financial Centres Index.

Rankings like these carry influence, yet they are typically reported without much examination of how they are constructed.

At a basic level, a financial centre performs four functions at scale:

  • Intermediating credit
  • Pooling and allocating long-term capital
  • Running markets
  • Providing cross-border connectivity

The GFCI index is produced by Z/Yen, a London-based commercial think-tank, and has been published twice a year since 2007. Since 2016 it has been developed in strategic partnership with the China Development Institute in Shenzhen.

If one were designing a ranking from first principles, the focus would likely fall on three areas: 1) the depth and breadth of products and markets, 2) the strength of financial intermediaries (broker-dealers, insurers, asset managers, exchanges, fintechs), 3) the quality of the enabling ecosystem (professional services, regulation, infrastructure, reputation).

The GFCI touches all three, but in a partial and indirect way. So what, in practice, does it actually measure?

Pillar one: instrumental factors

The first pillar of the GFCI is a wide-ranging collection of 147 "instrumental factors"— third-party quantitative indicators grouped into five areas: Business Environment, Human Capital, Infrastructure, Reputation, and Financial Sector Development. The scope is broad, spanning measures like quality of life, energy intensity of GDP, press freedom, railway density, the TomTom Traffic Index, and average precipitation. Many of these indicators matter to finance—but they would matter as much to any other global industry.

The most finance-specific category—Financial Sector Development—accounts for just 20 out of the 147 factors. Some choices are curious. The inclusion of the Forbes Billionaires list, the World Bank's Liner Shipping Connectivity Index, and DHL's Global Connectedness Index point to a loose conceptual approach. Equity market activity is captured through data from the World Federation of Exchanges, but so too is fixed income activity ("Value Of Bond Trading")—despite most global bond trading occurring over-the-counter. There are no direct measures of FX, commodities, derivatives, or private capital activity.

Pillar two: the participant survey

The second pillar is an open online questionnaire, allowing self‑identified financial services respondents to assess the centres they know. Geographically, 36% of respondents are based in Western Europe, 35% in the Asia Pacific and 16% in the Middle East and Africa, but only 6% in North America—a seeming underrepresentation given that North American centres occupy six of the top twenty positions.

To limit home bias, respondents' assessments of their own cities are excluded, meaning all scores are derived from outsiders' views. Coverage gaps are then filled using machine learning to estimate how respondents would have rated centres they didn't assess. The methodology does not disclose the relative weighting of survey responses versus machine‑generated predictions, nor the contribution of each pillar to the final score.

Whatever the precise method, the top four centres—New York, London, Hong Kong, Singapore—are separated by a single rating point. Further down the table, city rankings can be highly volatile: Chicago dropped eight places to 14th, Toronto fell the same distance to 29th, while Lugano and Osaka climbed five and ten spots respectively to 25th and 26th. Moves of this magnitude across a single six-month edition are striking.

Hong Kong's Comparative Strengths

The GFCI is best read as a structured opinion poll, scaffolded by a wide array of proxy indicators. On harder metrics, Hong Kong's genuine strengths cluster around a specific role: cross-border capital intermediation.

In wealth management, Hong Kong's proximity to private wealth has positioned it alongside Switzerland and Singapore as a premier offshore hub. The city's asset and wealth management industry reported approximately US$4.5 trillion in total AUM for 2024. Beyond that, however, asset management scale differs materially across markets: London, for instance, accounts for the lion's share of the UK fund industry's US$13 trillion AUM. BlackRock—headquartered in New York—manages roughly US$14 trillion (albeit globally).

Hong Kong's banking sector is one of the largest in Asia and a major node in global cross-border intermediation. In foreign exchange, Hong Kong ranks fourth by daily turnover, according to the BIS 2025 Triennial Survey, underscoring its role as a regional liquidity hub. In equity markets, Hong Kong sits sixth globally by market capitalization, but it currently leads the world in IPO fundraising as the favored offshore venue for Chinese listings. Secondary equity trading is substantial—but clearly behind the US and onshore China, and trailing Japan, Korea, at times Taiwan within the region.

Elsewhere the profile is mixed. In rates and credit, the domestic market remains modest relative to regional peers. Internationally, however, Hong Kong has emerged as the leading arranger of cross‑border debt for regional issuers within Asia. Listed derivatives trading via HKEX is meaningful but mid-table by global contract volume. Commodities trading and financing are still nascent; private capital is gaining traction, with Hong Kong an important anchor for Asia-focused PE fundraising. Insurance rounds out the picture: Hong Kong carries the world's highest penetration rate (premiums as a share of GDP), according to Swiss RE, but ranks much lower by total premiums due to its modest population size.

Hong Kong's most durable competitive edge will not come from matching New York or London across every asset class, but from focusing on the roles no other global centre can fill. That includes continuing to anchor renminbi internationalization and reinforcing its appeal as an offshore listing venue for Chinese companies. It also means building the capabilities that the next phase of the story requires: financing China's technology sector via offshore capital markets, scaling environmental and carbon markets, and facilitating the cross-border flows that follow. These are not supplementary opportunities; they are becoming the structural basis of Hong Kong's long-term advantage.

A paradox between competitiveness and institutional scale

Hong Kong's position in global finance has rested more on activity than ownership. Unlike other top financial centres, which evolved as the ultimate 'home' for global parent institutions, in the modern era of international finance, Hong Kong's growth was driven primarily by its role as a regional platform for firms headquartered elsewhere. Consequently, cities ranked well below Hong Kong serve as headquarters to institutions that are larger by balance‑sheet size, market capitalization, and global footprint. Toronto (ranked 29th) anchors Canada's entire financial system and hosts institutions like RBC, Manulife and Sun Life, and some of the world's largest pension funds. Paris (19th) houses globally prominent banking and insurance groups. Chicago (14th) underpins global derivatives markets. Singapore, ranked just below Hong Kong, combines international intermediation, homegrown regional champions, and globally formidable sovereign wealth funds. In these cities—and particularly in New York and London—generations of local talent have risen to divisional and group leadership at globally systemically important financial institutions.

This contrast frames Hong Kong's configuration. Aside from its platform role within global and Chinese financial systems, the city hosts a substantial base of locally headquartered financial firms. The majority, however, operate as local or regional players within their segments. A small number have achieved greater scale, with leadership and strategic functions substantively anchored in the city.

Hong Kong's stature as a global financial centre is clear. Its evolution now hinges not only on attracting activity—where it already excels—but on how fully institutional depth and the local opportunity landscape develop alongside that activity.
