Who Holds the World's Foreign Portfolio Investment? The 2025 Rankings

By the Economic Research Team  ·  Data: International Monetary Fund (IMF) — Portfolio Investment Positions Survey  ·  Last updated: 2025-S1

Introduction: Mapping the Invisible Architecture of Global Finance

Every year, trillions of dollars flow invisibly across borders — not as trade in goods, not as foreign direct investment in factories and subsidiaries, but as portfolio investment: the purchase of stocks, bonds and investment fund shares issued in another country. This cross-border capital is the connective tissue of modern financial markets. It determines who funds government deficits, who absorbs corporate bond issuance, and who bears the risk when markets fall.

The IMF's Coordinated Portfolio Investment Survey (CPIS), published under the Portfolio Investment Positions (PIP) dataset, is the most comprehensive attempt to map this invisible architecture. Eighty-plus economies report their cross-border portfolio holdings twice a year, allowing analysts to trace — with meaningful granularity — who owns what, where, and in what form. The latest data, covering 2025-S1, reveals a world still dominated by a handful of advanced economies, shaped by three structural forces that a raw ranking table alone cannot explain.

The United States: $17.6 Trillion and Counting

The headline figure is stark. With $17,599 billion in total outward portfolio investment, the United States holds more foreign equity and debt than the next four economies combined — Germany ($5,527B), the United Kingdom ($5,059B), Japan ($4,809B), and France ($4,309B). The G7 economies collectively account for roughly $42,908 billion — the overwhelming share of all reportable cross-border portfolio capital in the world.

This concentration reflects the depth of US capital markets. American pension funds, mutual funds, insurance companies, and endowments operate at a scale that dwarfs their peers: the US accounts for roughly half of global equity market capitalisation, and its asset management industry has no international equal. When a California pension fund diversifies internationally, it moves markets in emerging economies. When a US money market fund shifts allocations, it affects sovereign bond yields in Europe.

The Distortion: When Luxembourg and the Cayman Islands "Outrank" China

A raw CPIS ranking throws up a result that stops most readers cold: Luxembourg ($7,117B), the Cayman Islands ($6,896B), and Ireland ($6,345B) all rank above Germany and the United Kingdom in terms of total reported outward portfolio assets. Combined, these three jurisdictions — with a collective GDP smaller than the Netherlands — nominally "hold" more portfolio assets than any economy outside the United States.

This is the fund domicile effect. Under international accounting standards, investment vehicles are attributed to the economy where they are legally registered, not where their underlying investors reside. The $7 trillion attributed to Luxembourg represents UCITS funds registered under EU law but managed from London, Frankfurt and Paris, and owned by savers across the continent. The Cayman Islands figure reflects hedge funds and private credit vehicles legally domiciled offshore. Ireland hosts the European platforms of US asset managers from BlackRock to Vanguard. None of these figures represent domestic Irish, Luxembourgish or Cayman capital — they represent the legal geography of fund registration. The table below excludes all three to show the true investor-country picture.

China at Rank 13: Capital Controls and the Missing $3 Trillion

China's position at 13th place with $1,694 billion is the data point most likely to prompt a double-take. The world's second-largest economy, with a GDP approaching $19 trillion, holds less in foreign portfolio assets than Switzerland or Singapore — economies a fraction of its size.

Two structural factors explain this. First, China maintains strict capital controls on outward portfolio investment. Chinese residents — individuals, corporations, and institutions alike — face legal limits on transferring wealth abroad and purchasing foreign securities. Programmes such as QDII (Qualified Domestic Institutional Investor) and the Northbound Stock Connect provide controlled channels, but aggregate outflows remain capped well below what GDP-adjusted comparisons would suggest.

Second, and critically: China's $3.2 trillion in foreign exchange reserves, managed by SAFE (State Administration of Foreign Exchange) and the People's Bank of China, do not appear in this data at all. Under the Balance of Payments Manual 6th Edition (BPM6) — the international standard that governs CPIS — central bank reserve assets are classified separately from portfolio investment and excluded from the survey. The same exclusion applies to Japan's $1.2 trillion in reserves, the UK's holdings, and every other central bank in this ranking. The CPIS measures portfolio investment, not sovereign reserve management. China's true claim on foreign assets is vastly larger than $1.7 trillion — but the reserves portion is simply not in this dataset.

The Norway Exception: When Government Is the Investor

Norway provides the clearest illustration of what the government sector (S13) column in this dataset reveals. Of Norway's $2,104 billion in total outward portfolio assets, $1,745 billion — 83% of the total — is attributed to the general government sector. This is the Government Pension Fund Global (GPFG), the world's largest sovereign wealth fund, managed by Norges Bank Investment Management on behalf of the Norwegian state.

Norway's ratio is exceptional. For the United States, the government sector reports zero — US public pension assets and Social Security Trust Funds are invested domestically or classified differently. Germany, France and Canada show modest government holdings relative to their totals. Norway alone has built a structure where the state is, unambiguously, the dominant foreign portfolio investor in the economy.

Excludes Luxembourg, Cayman Islands and Ireland (fund domicile effects). All figures in USD billions. Govt Sector (S13) captures sovereign wealth funds and direct government holdings where separately reported.

What This Tells Us — and What It Doesn't

Three takeaways emerge from this dataset for practitioners and policymakers alike.

Advanced economies remain overwhelmingly dominant in cross-border portfolio allocation. The G7 alone accounts for a share of global portfolio assets that no emerging market trajectory is likely to challenge in the near term — even accounting for China's suppressed figures.

The fund domicile effect is a genuine analytical hazard. Any research team working from raw CPIS data without filtering for domicile jurisdictions will misread the source of global capital. Luxembourg is not a capital exporter — it is a legal address. The distinction matters when assessing geopolitical exposure, sanctions risk, or bilateral investment dependencies.

Reserve assets are the invisible elephant. The combined foreign reserves of China, Japan, Switzerland and others — running to roughly $7–8 trillion — are absent from this dataset entirely. CPIS answers the question "where does private and institutional cross-border investment come from?" It does not answer "who holds the most foreign assets overall?" Those are different questions, with different data sources.

Data source: International Monetary Fund (IMF), Portfolio Investment Positions (PIP) dataset, Coordinated Portfolio Investment Survey (CPIS). Data reflects semiannual positions (S = semiannual frequency), total outward portfolio investment (equity + debt securities), all reporting sectors combined (S1). Government sector column reflects S13 (general government) subsector where separately reported. Luxembourg, Cayman Islands and Ireland excluded from ranking due to fund domicile effects — their aggregate figure is noted in the analysis above. Central bank reserve assets are excluded from PIP by definition under BPM6.
