The world’s largest and most reliable banks are concentrated in a relatively small number of countries. In 2025, institutions from Switzerland, Canada, Singapore, the UAE, the US, China, and France continue to lead international rankings thanks to their financial stability, massive asset bases, high credit ratings, and global influence. Among them are Zuercher Kantonalbank, Royal Bank of Canada, DBS Bank, First Abu Dhabi Bank, JPMorgan Chase, ICBC, and BNP Paribas. In this article, we look at why these banks are considered among the strongest in the world and which criteria are commonly used to assess banking reliability.
How We Evaluated the Banks
This article is based on several authoritative international sources, including rankings published by Forbes and the annual safest banks rankings by Global Finance magazine. In the Global Finance World’s Safest Banks 2025 methodology, banks are evaluated according to long-term foreign currency ratings assigned by Fitch, S&P, and Moody’s. The ranking includes major banks by asset size that hold at least two ratings from these agencies.
We also include the S&P credit rating for each bank. Unlike magazine rankings, rating agencies do not assign first or second places. Instead, they assess a bank’s or banking group’s ability to meet its financial obligations. At the same time, it is important to understand that a credit rating does not guarantee the safety of client funds. It reflects the agency’s opinion regarding the creditworthiness of a bank or issuer at a specific point in time and may later be revised.
AAA is the highest possible creditworthiness rating on the S&P scale and indicates an extremely strong ability to meet financial commitments. Ratings in the AA and A categories are also considered high quality, although they imply greater sensitivity to adverse economic conditions. The probability of default becomes more significant once ratings fall into the BBB category and increases substantially in the CCC range.
Zuercher Kantonalbank
Country: Switzerland
Assets: $262.4 billion S&P Rating: AAA
Specialisation: retail and corporate banking, investment services.
One of Switzerland’s largest banks, Zuercher Kantonalbank operates branches in multiple countries. Although it is less well known among clients from Russia and Belarus and primarily serves Swiss and EU residents, its key strength is reliability. Despite having relatively smaller assets compared to some global banking giants, the bank maintains the highest credit ratings from leading agencies and is considered one of the world’s most stable financial institutions.
In the Global Finance ranking, first place was awarded to the German quasi-governmental bank KfW, which focuses mainly on infrastructure financing and does not significantly operate in retail banking.
Zuercher Kantonalbank was founded in 1870 and has close ties to the Canton of Zurich. During the 19th century, Zurich became one of Switzerland’s key centers of industrial and financial development. However, access to financing remained limited, and small and medium-sized businesses struggled to obtain affordable credit due to banking monopolies.
This contributed to growing political pressure and demands for broader civil rights. One of the key demands from opposition groups was the establishment of an independent cantonal bank capable of supporting local businesses and economic growth. This ultimately led to the creation of Zuercher Kantonalbank.
Royal Bank of Canada
Country: Canada
Assets: $1.69 trillion
S&P Rating: AA-
Specialisation: a broad range of financial services for individuals and corporations.
Royal Bank of Canada is one of the largest and most recognized banks in North America. RBC provides retail banking, investment services, asset management, insurance, and corporate banking solutions. In 2025, Global Finance once again named RBC the safest bank in North America.
The bank was founded on July 1, 1864, in Halifax. It played an active role in financing Canada’s railway construction and gradually expanded into every Canadian province. RBC entered international markets as early as 1882 with the opening of an office in Bermuda and has continued expanding globally ever since.
Throughout its history, RBC has also been known for adopting new technologies. In 1961, the bank became one of the first to install a computer in one of its offices — at the time, the machine was considered highly unusual and was roughly the size of a large wardrobe.
DBS Bank
Country: Singapore
Assets: $700.7 billion
S&P Rating: AA-
Specialisation: retail banking, investment banking, asset management, insurance, and related financial services.
In 2025, DBS was named Asia’s safest bank by Global Finance for the 17th consecutive year and ranked second among the world’s 50 safest commercial banks.
DBS Bank is one of Asia’s largest and most recognized retail banks. Established in 1968, it was originally created to support Singapore’s economic development and industrialisation efforts. Over time, DBS evolved beyond its original role as a development institution and became one of the region’s leading financial groups. Today, DBS describes itself as a leading Asian financial services group with operations across 19 markets.
The bank is also widely recognized as a technological leader in the banking industry. DBS actively develops digital banking products, data analytics solutions, automated customer service systems, and corporate banking technologies.
First Abu Dhabi Bank
Country: United Arab Emirates (UAE)
Assets: $381 billion
S&P Rating: AA-
Specialisation: retail and investment banking services.
First Abu Dhabi Bank is a leading financial institution in the Middle East. It is the largest bank in the UAE and one of the largest banking groups across the Middle East and North Africa region. In the Global Finance World’s Safest Banks 2025 ranking for the Middle East, FAB ranked second.
First Abu Dhabi Bank is also the youngest financial institution featured in this article. It was established in 2017 following the merger of two major UAE banks — First Gulf Bank and National Bank of Abu Dhabi. The merger became one of the largest financial transactions in the region’s history. Today, the bank continues to expand internationally.
JPMorgan Chase
Country: United States
Assets: $4.4 trillion
S&P Rating: A+ (An A+ rating indicates a very high ability to meet financial obligations, although it is one level below AA- and significantly below the highest AAA rating.)
Specialisation: full range of financial services, though it is particularly associated with wealth management and investment banking.
JPMorgan Chase is one of the world’s largest and most influential banks and has played a major role in the development of the international banking system. In 2022, the bank was recognized by Global Finance as the world’s best corporate bank and best private bank. In the Forbes Global 2000 ranking for 2025, JPMorgan Chase ranked first globally for the third consecutive year.
The institution traces its origins back to 1799 in New York, where it began as Burr, David and Company. Through numerous mergers and acquisitions, it eventually evolved into the modern financial giant JPMorgan Chase & Co.
Over the course of its history, the company played a key role in financing and consolidating major industrial corporations, including United States Steel and General Electric, as well as infrastructure projects such as railway networks, the Statue of Liberty, and the Brooklyn Bridge. The bank was also among the first to begin serving female clients.
Industrial and Commercial Bank of China (ICBC)
Country: China
Assets: $7.86 trillion
S&P Rating: A
Specialisation: a broad range of financial services for individuals and corporations.
ICBC is the largest bank in the world by assets and controls roughly one-fifth of China’s banking system. In the Forbes rankings, it consistently occupies leading positions by asset size.
ICBC was founded in 1984 and received permission to open an office in New York in 1991. In 2008, the bank signed the Equator Principles — an international framework that helps financial institutions manage environmental and social risks in project financing.
ICBC also plays an important role in China’s global “Belt and Road” investment initiative. In addition, it is one of China’s largest employers, with approximately 450,000 employees worldwide.
BNP Paribas
Country: France
Assets: $3.25 trillion
S&P Rating: A
Specialisation: corporate banking, investment services, international trade finance, and services for private and institutional clients.
BNP Paribas is one of Europe’s largest banking groups and a major player in international finance. The bank serves private clients, corporations, institutional investors, and international businesses. The group operates in 64 countries.
In 2025, Global Finance named BNP Paribas the world’s best provider of trade finance services. Trade finance includes cross-border corporate operations such as supply chain financing, letters of credit, guarantees, working capital management, and international trade support.
BNP Paribas has developed this segment as a global service for companies operating with international suppliers, buyers, and logistics chains. According to Global Finance, the bank’s trade finance network covers 44 countries, more than 100 trade centers, and operations in over 60 countries.
The history of BNP Paribas is linked to several major French financial institutions. Banque Nationale de Paris (BNP) was established in 1966 through the merger of BNCI and CNEP. The modern BNP Paribas group was formed on May 23, 2000, following the merger of BNP and Paribas.
Conclusion
There is no single “best” international bank for every client. Some institutions stand out for maximum financial stability and government backing, while others dominate through global reach, investment services, technological innovation, or corporate banking expertise. At the same time, the world’s largest and most reliable banks tend to share several common characteristics: strong capital reserves, high credit ratings, diversified operations, and long-term resilience during periods of economic uncertainty. For internationally minded investors, entrepreneurs, and globally mobile families, understanding these factors is often more important than simply choosing the biggest bank by assets.
