The $164 Trillion
Bank Network,
Mapped in 3D

How to read the map

Each bubble's area represents total assets. Its radius grows with the square root of the balance sheet. ICBC has $6.69 trillion, about nine times National Australia Bank's $749 billion. Its bubble therefore covers nine times the area but is only three times as wide. A linear width scale would make ICBC cover about eighty times the area.

A halo marks a bank that the Financial Stability Board classifies as globally systemically important. The full FSB list contains 29 banks, including 27 of this top 50. The halo shows regulatory status, not asset size.

The layout groups banks by region. Nearby bubbles usually share a market and regulatory environment, but their position does not show loans, deposits or any other financial exposure between them.

China's four largest banks hold $23 trillion

ICBC, Agricultural Bank of China, China Construction Bank and Bank of China together carry roughly $23.0 trillion in assets. The same ranking contains 6 US banks: JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs and Morgan Stanley. Together they hold about $14.4 trillion. The four Chinese banks account for 24% of all assets in the top 50 and share a controlling state owner.

Chinese institutions occupy 13 of the 50 places. Across the full ranking, Asia Pacific has 432 banks, Europe 223, and North America 155. That distribution produces the dense orange cluster on the map.

The scale is easier to grasp through a smaller number. Our inflation calculator shows what $10,000 from 2008 is worth now. ICBC's balance sheet contains that original $10,000 amount 669 million times.

Why bank size and systemic importance differ

BNY, with roughly $416 billion in assets, and State Street, with roughly $353 billion, both sit outside the top 50. Both are G-SIBs. As custodian banks, they hold and settle securities for other institutions, so the volumes passing through them can dwarf their own balance sheets. Total assets and systemic importance are separate measures.

HSBC Hong Kong presents the opposite problem. It reports $1.41 trillion in assets and would rank 29th as a standalone bank, but it belongs to HSBC Holdings, which ranks 7th. The map draws the parent and subsidiary as connected nodes because adding both balance sheets together would count some assets twice.

Who owns the world's largest banks?

The Who owns it colour mode separates state control, concentrated private ownership and widely held public banks. China's largest banks sit mainly in the first group. Central Huijin Investment is wholly owned by China Investment Corporation and was capitalised in December 2003 with $20 billion of central bank reserves. It holds 64.13% of Bank of China, 57.14% of China Construction Bank, 40.14% of Agricultural Bank of China and 34.79% of ICBC. Add direct Ministry of Finance stakes and combined state control of ICBC reaches roughly 69% to 71%.

India also uses direct state ownership. The government held 57.4% of State Bank of India on 31 March 2025, above its statutory floor of 51%. Ownership is more dispersed in the United States and Europe. BlackRock, Vanguard and State Street Global Advisors together are the largest shareholder in almost 90% of S&P 500 companies. Their combined stake rose from 13.5% in 2008 to 22.2% in 2023. Vanguard alone reports about 9.4% of JPMorgan Chase. This pattern follows from the growth of index funds rather than a regulatory plan.

MUFG's stake in Morgan Stanley creates the long line between Asia and North America. MUFG owns 24.12%, or 380,511,118 shares. The position began with a $9 billion rescue investment in October 2008 and remains in place. The banks also operate a securities joint venture split 60/40. It is the world's largest cross-continental stake between banks.

The inflation calculators put the dates around that deal in context. Compare $1,000 from 1929 with ¥10,000 from 1990, from the year Japan's banking bubble began to deflate.

One bank on this map no longer exists

Credit Suisse is drawn as a wireframe. On 19 March 2023 UBS agreed to buy it for CHF 3 billion in an all-stock deal brokered by the Swiss government and FINMA. The merger closed on 12 June 2023. Shareholders received one UBS share for every 22.48 Credit Suisse shares. The Swiss National Bank provided a credit line of up to CHF 100 billion, and the government guaranteed up to CHF 9 billion of losses above the first CHF 5 billion that UBS absorbed.

This was the largest change to the network since 2008. Every relationship in the dataset therefore carries an as of date. Combining a 2026 acquisition, a 2024 ownership stake and a 2022 exposure without dates would show relationships that did not exist at the same time.

Can you see which banks lend to each other?

No public dataset identifies loans, deposits or derivatives positions between two named banks. The Bank for International Settlements publishes international banking statistics by reporting banking system and counterparty country, not by bank pair. Its tables cannot show a JPMorgan to BNP Paribas exposure. Correspondent banking data would identify payment hubs regardless of balance-sheet size, but Swift's KYC Registry is a controlled utility in which each institution decides who may see its information. There is no public list of which banks hold accounts with one another.

This map draws 34 disclosed ownership, control, joint venture and merger relationships. Each has a named source and date. It does not estimate bank-to-bank exposure. A maximum entropy model could produce a plausible exposure matrix, but those lines would be modelled rather than verified.

The public relationships still reveal unusual partnerships. Crédit Agricole and Santander compete in European retail banking but jointly own CACEIS, a custody business, at 69.5% and 30.5%. Qatar's sovereign fund invested £4 billion in Barclays in 2008 and now holds about 2.83%. BlackRock holds about 2.84%, so Qatar is no longer clearly the bank's largest shareholder.

The 50 largest banks in the world by assets

The ranking uses total assets from FY2024 accounts in the TAB Global 1000 2025 edition, with a 31 March 2025 cut-off. The Financial Stability Board published the G-SIB buckets on 26 November 2024.

G-SIB means global systemically important bank. The FSB assigns each G-SIB to a bucket linked to an extra capital buffer. Bucket 1 requires 1.0%, bucket 2 requires 1.5%, bucket 3 requires 2.0%, and bucket 4 requires 2.5% of risk-weighted assets.
