Turkey’s largest banks in 2026 include a mix of state-owned institutions, private banks, foreign-controlled banks, and participation banks. The sector remains profitable despite high interest rates, inflation, currency risk, and regulatory scrutiny.
Turkey’s leading banks include:
- Ziraat Bankası.
- Türkiye İş Bankası.
- VakıfBank.
- Halkbank.
- Garanti BBVA.
- Akbank.
- Yapı Kredi.
- QNB Türkiye.
- DenizBank.
- Kuveyt Türk.
Together, these institutions dominate the Turkish banking market by assets, branch networks, customer base, and influence. Some are state-owned, some belong to major international banking groups, and Kuveyt Türk represents the Islamic finance sector.
Turkey’s Banking Sector In 2026
Turkey’s banking sector remains one of the largest and most developed in the region, but it operates in a difficult macroeconomic environment.
Key figures and conditions include:
- The Turkish banking sector generated TRY 288.4 billion in net profit in the first quarter of 2026.
- The Central Bank of Turkey’s benchmark interest rate stands at 37%.
- Annual inflation reached 32.37% in April 2026.
- Banks face high funding costs, currency-related risks, and increased regulatory scrutiny.
- Fitch reaffirmed Turkey’s sovereign credit rating at BB- with a Stable Outlook in April 2026.
- Fitch also revised the outlooks of several Turkish banks to stable.
The increase in banking sector profit should be viewed in the context of high inflation. It does not necessarily represent a dramatic rise in real terms, but it shows that the sector has remained profitable under difficult conditions.
International ratings of Turkish banks are shaped not only by each bank’s individual performance, but also by Turkey’s wider sovereign risk profile.
Ziraat Bankası
Ziraat Bankası is Turkey’s largest state-owned bank and one of its oldest financial institutions.
Founded in 1863 to support agriculture, Ziraat has grown into a universal financial group serving individuals, businesses, corporate clients, agriculture, international trade, investment services, and digital banking customers.
By the end of 2025, Ziraat remained Turkey’s largest bank, with assets of approximately TRY 8.47 trillion.
Its network includes:
- 1,769 branches, including international locations.
- Nearly 7,900 ATMs.
- A broad domestic presence across major cities, smaller towns, and regional markets.
This branch network can be useful for clients buying real estate, obtaining residence permits, receiving salaries, paying utility bills, or running businesses in Turkey.
Ziraat also operates as the core of a larger financial group, with subsidiaries in:
- Islamic banking.
- Brokerage services.
- Asset management.
- Real estate.
- Information technology.
- Electronic money.
- Digital banking.
- Leasing.
The group also has subsidiaries, branches, and representative offices in 20 countries, including Germany, the United Kingdom, Kazakhstan, Azerbaijan, Uzbekistan, Georgia, Bosnia and Herzegovina, Kosovo, and other markets.
Foreign nationals often consider Ziraat as one of their first banking options in Turkey. However, account-opening requirements are not standardized across branches. One branch may accept an application without a residence permit, while another may request more documents or reject the application after compliance review.
Applicants may be asked for:
- Valid passport.
- Turkish tax identification number.
- Local Turkish phone number.
- Proof of address.
- Residence permit, if applicable.
- Documents confirming source of funds and purpose of opening the account.
Türkiye İş Bankası
Türkiye İş Bankası was founded in 1924 at the initiative of Mustafa Kemal Atatürk, Turkey’s first president. It was created to help finance the national economy during the country’s post-World War I recovery.
It was also the first Turkish bank whose shares were listed on the stock exchange.
After World War II, İş Bankası became an important participant in international trade, acting as a financial intermediary for Turkish businesses.
The bank operates more than 1,100 branches, giving it the largest branch network among private banks in Turkey.
İş Bankası has a long record of technological innovation. In 1982, it introduced Turkey’s first ATMs under the Bankamatik brand.
More recently, it became the first bank in Turkey to conduct an international transaction through the Visa B2B Connect network, which allows commercial clients to transfer funds to bank accounts worldwide, regardless of whether the recipient bank is part of the Visa network.
VakıfBank
VakıfBank was established in 1954 to manage assets belonging to vakıfs, Islamic religious and charitable foundations that historically played an important role in Turkey’s social and economic life.
The bank operates nearly 950 branches and has one of Turkey’s largest branch networks. It also maintains an international presence through branches and representative offices in Europe and other regions.
VakıfBank has invested in digital products. In 2022, it launched Vibox, a mobile app for children under 18. The app allows parents to transfer pocket money, while young users learn financial management and savings through interactive tools.
After 2022, VakıfBank periodically opened accounts for foreign nationals, but requirements varied by branch. Depending on the circumstances, the bank could request a residence permit and proof of address. The source article appears cut off at this point, so any further requirements are unclear.
Türkiye Halk Bankası
Türkiye Halk Bankası, known as Halkbank, is a state-owned bank founded in 1933 to support craftsmen, artisans, and small businesses.
The bank now operates more than 1,000 branches.
Over time, Halkbank expanded its operations, absorbed several state-owned banks, and acquired the major Turkish lender Pamukbank.
Today, Halkbank offers a broad range of financial services, with a particular focus on small and medium-sized enterprises. It has also supported entrepreneurs and businesses in regions affected by earthquakes, while continuing to provide retail banking services to individual customers.
Garanti BBVA
Garanti BBVA was founded in Ankara in 1946.
Its principal shareholder is Banco Bilbao Vizcaya Argentaria, one of Spain’s largest banking groups, with a major presence across Latin America. BBVA owns 85.97% of Garanti BBVA’s shares.
Garanti BBVA operates more than 800 branches.
As of March 2026, the bank described itself as Turkey’s second-largest private bank, with consolidated assets of TRY 4.8 trillion.
It is considered one of Turkey’s most technologically advanced banks and is among the leading private banks in the country.
Akbank
Akbank was founded in 1948 to finance local cotton producers and later became one of Turkey’s major banks.
It operates more than 700 branches.
Akbank offers a wide range of services, including:
- Corporate banking.
- Investment banking.
- Trade finance.
- International business operations.
- Retail banking.
- Private banking.
The bank also has several international branches, mainly in Europe.
Akbank is widely regarded as one of Turkey’s most technologically advanced financial institutions and regularly scores highly in customer service rankings.
In 2023, Akbank’s investment division acquired the Turkish cryptocurrency company Stablex, showing the bank’s interest in the digital asset sector.
Account-opening rules vary across branches and depend on the client profile, residence status, source of funds, and compliance review.
Yapı Kredi Bankası
Yapı Kredi Bankası was established in 1944 and became one of Turkey’s first major private banks.
The bank operates more than 800 branches.
Today, Yapı Kredi is part of Koç Group, which owns 61.17% of its shares. Italy’s UniCredit was previously a shareholder, but fully exited its stake in 2022.
The bank is described as having strong stability and efficiency indicators, which are used to assess investment performance relative to risk and the bank’s ability to manage risk against generated profits.
Yapı Kredi invests heavily in technology. Its mobile banking application is available in several languages, including French and Spanish.
Like Akbank, Yapı Kredi regularly ranks highly in customer service evaluations and is considered convenient for international money transfers.
QNB Türkiye
QNB Türkiye, formerly QNB Finansbank, was founded in 1987 by Turkish banker Hüsnü Özyeğin.
The bank became part of Qatar National Bank Group in 2016 and rebranded from QNB Finansbank to QNB Türkiye in 2024.
It operates more than 400 branches.
QNB Türkiye is part of one of the largest banking groups in the Middle East and has extensive international backing.
The bank has also been involved in social initiatives. In 2020, it received an award from Euromoney for customer support during the pandemic. The European Bank for Reconstruction and Development also provided QNB Finansbank with credit lines to support female entrepreneurship in Turkey and lending to businesses participating in the EBRD’s Women in Business program.
According to local media reports, QNB Türkiye is one of Turkey’s most active lenders. Foreign client accounts are opened subject to compliance checks.
DenizBank
DenizBank is fully owned by Emirates NBD Bank PJSC.
The bank was founded in 1938 as a regional private bank and has changed ownership several times.
In 2012, Sberbank acquired DenizBank from the Franco-Belgian financial group Dexia. Sberbank later sold the bank at a loss after sanctions were imposed on Russian financial institutions.
DenizBank operates nearly 700 branches.
It is one of the most recognized Turkish banks among international clients and has a reputation as a client-friendly and accessible financial institution.
After 2022, DenizBank tightened policies toward non-residents several times. In practice, it may request:
- Residence permit.
- Proof of address.
- Turkish tax number.
- Deposit.
- Documents confirming source of funds.
Kuveyt Türk Katılım Bankası
Kuveyt Türk Katılım Bankası is Turkey’s largest participation bank and the only Islamic finance institution among Turkey’s ten largest banks by assets as of 2025.
It operates under an interest-free banking model and offers retail, corporate, and investment products that comply with Islamic finance principles.
According to its 2025 Corporate Governance Report, Kuveyt Türk served clients through 448 branches in Turkey. It also has an international presence through its Bahrain branch and KT Bank AG in Germany.
Kuveyt Türk may be relevant for investors and entrepreneurs seeking participation finance products, including:
- Participation accounts.
- Trade finance solutions.
- Real estate financing.
- Sharia-compliant financial products.
Banking Access For Foreign Clients
Requirements for foreign clients differ by bank and often by branch.
Banks may assess:
- Residency status.
- Source of funds.
- Purpose of the account.
- Compliance review outcome.
- Local address documentation.
- Turkish tax number.
- Whether the applicant has a residence permit.
Turkey remains a popular destination for international banking, business relocation, real estate investment, and citizenship by investment, but foreign clients should expect account-opening rules to vary significantly across institutions and branches.
Practical Comparison
Turkey’s banking sector differs from the American or British banking markets. It is more diversified and does not have a single dominant banking institution.
The largest banks include:
- State-owned banks such as Ziraat, VakıfBank, and Halkbank.
- Private banks such as İş Bankası, Akbank, and Yapı Kredi.
- Foreign-controlled banks such as Garanti BBVA, QNB Türkiye, and DenizBank.
- Participation finance institutions such as Kuveyt Türk.
For foreign clients, the practical choice depends not only on bank size, but also on branch accessibility, account-opening flexibility, digital banking quality, international transfer needs, language support, compliance requirements, and whether the client needs conventional or Islamic finance products.
