The Largest Banks in Bulgaria: Rankings by Assets and Profit, Sector Overview and What Foreign Investors Need to Know

A practical guide to the Bulgarian banking sector for foreign businesses, property buyers and investors: who the major players are, how the sector is supervised, and how to choose a bank for your needs

Introduction

The Bulgarian banking sector is one of the most stable and well-capitalised in Central and Eastern Europe. Following the banking crisis of 1996–1997 – which led to the introduction of the Currency Board and pegged the lev to the Deutsche Mark, and subsequently the euro – the sector underwent a complete restructuring. Today it operates under the direct supervision of the Bulgarian National Bank (BNB) and, for the largest institutions, under the Single Supervisory Mechanism of the European Central Bank.

For a foreign investor, business owner or property buyer operating in Bulgaria, understanding the banking landscape is practically important: it affects where you can open a business account, from whom you can obtain a mortgage, which banks are most likely to service your specific needs efficiently, and what to expect in terms of documentation requirements and processing times.

This guide provides a ranked overview of the largest Bulgarian banks by assets and profitability, an explanation of the regulatory framework, and practical guidance for foreign clients navigating the Bulgarian banking system.

Section 1. The Bulgarian Banking Sector – Key Facts

Structure and Scale

As of March 2026, 17 banks licensed in Bulgaria plus 6 branches of foreign banks were operating in the country. The sector is highly concentrated: the five largest banks by assets account for over 65% of total sector assets, and the top ten account for approximately 90%. Total banking sector assets exceeded €92 billion in 2025 (approximately BGN 180 billion), representing approximately 155% of GDP – a level consistent with the EU average for a mid-sized economy.

The sector is predominantly foreign-owned: the majority of Bulgaria’s largest banks are subsidiaries of major European banking groups, including OTP (Hungary), KBC (Belgium), UniCredit (Italy) and Eurobank (Greece). This ownership structure brings European capital standards, risk management frameworks and product sophistication, while also meaning that strategic decisions are made at group level.

Profitability in 2025

The Bulgarian banking sector delivered record profitability in 2025, driven by strong lending activity, interest income and asset quality. Bulgaria had not yet joined the eurozone in 2025; euro adoption took effect on 1 January 2026. Net profit for the sector as a whole reached historic highs, with the largest five banks each reporting profit figures significantly above their pre-eurozone levels.

This profitability reflects both the structural advantage of operating in a growing economy with a low NPL ratio and the temporary benefit of the interest rate environment. As rates normalise, sector profitability is expected to moderate – but the underlying fundamentals of the Bulgarian banking sector remain sound.

Section 2. The Largest Bulgarian Banks – Rankings by Assets and Profit

The following rankings are based on data from Forbes Bulgaria (Q3 2025 and full-year 2025 reports) and the Bulgarian National Bank’s banking sector financial reports. These rankings reflect the current banking landscape following the mergers of Raiffeisenbank into UBB (2023) and Societe Generale Expressbank into DSK Bank (2020).

Section 3. The Regulatory Framework – How Bulgarian Banks Are Supervised

The Bulgarian National Bank

The Bulgarian National Bank (BNB) is the sole banking supervisor in Bulgaria and the issuing authority for banking licences. All licensed credit institutions are subject to BNB supervision, which encompasses licensing, ongoing prudential supervision, on-site inspections, enforcement and resolution. Bulgaria operated a currency board with the lev fixed to the euro until euro adoption. Bulgaria adopted the euro on 1 January 2026 at the irrevocable conversion rate of BGN 1.95583 per euro, after which the currency board ceased to operate.

The BNB publishes monthly and quarterly banking sector financial reports, which provide detailed data on assets, liabilities, capital adequacy, liquidity and profitability for each licensed institution. These reports are publicly accessible at bnb.bg and are the primary source for the rankings presented in this article.

ECB Single Supervisory Mechanism

Following Bulgaria’s eurozone accession on 1 January 2026, the largest Bulgarian banks – those classified as ‘significant institutions’ under ECB criteria – came under the direct supervision of the European Central Bank’s Single Supervisory Mechanism (SSM), with the BNB acting as national competent authority. UniCredit Bulbank and DSK Bank are the primary Bulgarian institutions subject to direct ECB supervision. This means their capital requirements, risk assessments and strategic plans are reviewed at European level.

Deposit Protection

Deposits are protected up to €100,000 per depositor per bank. Since Bulgaria adopted the euro on 1 January 2026, the guarantee should be stated in euros rather than as the former BGN 196,000 equivalent. This is the EU standard level of deposit protection. Since eurozone accession, Bulgaria’s deposit protection framework has been fully aligned with the EU Deposit Guarantee Schemes Directive.

Section 4. Opening a Bank Account in Bulgaria as a Foreign National

Individual Accounts

Foreign nationals who are residents of Bulgaria – holding a valid residence permit – can open a Bulgarian bank account on the same terms as Bulgarian citizens. The standard documentation requirements are: valid passport or identity document, Bulgarian personal identification number (ЕГН or ЛНЧ), proof of Bulgarian address (lease agreement, utility bill), and in some cases, a source of funds declaration for amounts above certain thresholds.

Non-resident foreign nationals – those without Bulgarian residency – can also open accounts at most Bulgarian banks, though the process is more onerous and the range of products available may be limited. Non-resident account opening may be available at major Bulgarian banks such as UniCredit Bulbank, UBB, DSK Bank and Eurobank Bulgaria, subject to each bank’s AML/KYC policy. Raiffeisenbank Bulgaria no longer exists as a separate bank.

Business Accounts for Foreign-Owned Companies

A Bulgarian-registered company (EOOD or AD) owned by a foreign national requires a Bulgarian business account to operate. The account is opened in the company’s name and requires: the company’s registration certificate from the Commercial Register, the company’s tax registration number (ЕИК), the director’s valid identity document, a declaration of beneficial ownership, and – for anti-money laundering compliance – documentation of the company’s business activity and expected transaction profile.

The AML compliance requirements for business account opening have tightened significantly in recent years, particularly following Bulgaria’s inclusion on the FATF grey list. Processing times for business account opening vary from 3–5 days at the most efficient banks to 3–4 weeks where additional due diligence is required. Engaging a local legal advisor to prepare the documentation package in the correct format reduces processing time materially.

Section 5. Mortgage Lending – Which Banks Are Most Relevant for Foreign Buyers

Mortgage lending to foreign nationals in Bulgaria is available at all major banks, subject to standard creditworthiness and documentation requirements. Since eurozone accession on 1 January 2026, all new mortgages are denominated in euros – eliminating the currency risk that previously existed for euro-income borrowers taking lev-denominated loans.

The Most Active Mortgage Lenders for Foreign Buyers

• DSK Bank maintains the largest retail mortgage book in Bulgaria and is the most active lender for standard residential mortgage applications, including from foreign nationals with Bulgarian residency. Its nationwide branch network and standardised product range make it the most accessible option for buyers outside Sofia.
• UniCredit Bulbank is the preferred choice for foreign corporate clients, high-value transactions and buyers with income sources in other European countries – its connection to the UniCredit European network facilitates income verification and cross-border documentation. It is also the most active construction finance lender.
• UBB and Postbank are competitive in the mortgage market and are particularly active in Sofia and major cities.
• Fibank offers competitive mortgage products, particularly for Bulgarian nationals and residents with domestic income sources.

Section 6. Construction Finance and Developer Lending

The construction lending market in Bulgaria is dominated by the same top-five banks that lead the sector overall. Construction finance – project loans to property developers – is a significant component of corporate lending portfolios and has expanded substantially alongside the construction boom of 2024–2025.

From the perspective of a foreign buyer purchasing off-plan, the identity of the developer’s construction finance bank matters for two reasons: first, a reputable European bank’s willingness to fund the project is indirect evidence that the project, the developer and the land title have been assessed and found acceptable – banks conduct their own due diligence before committing construction finance. Second, the bank’s mortgage discharge mechanism – how it releases individual apartment titles from the construction mortgage as units are sold – directly affects the buyer’s ability to obtain clean title at completion.
