Bulgarian National Bank (Българска национална банка - BNB)

Overview

The Bulgarian National Bank (BNB) serves as the central bank of Bulgaria and the monetary authority for the Republic of Bulgaria. Founded on 25 January 1879 by Royal Decree, the BNB is one of the oldest continuously operating central banks in the world (13th oldest). The Bank was officially opened on 23 May 1879 and carried out its first banking operation on 6 June 1879.

Current Governor: Dimitar Radev (appointed 14 July 2015, continuing in 2026)

Headquarter Location: Sofia, Bulgaria

Euro Adoption (January 2026)

Bulgaria adopted the euro as its official currency on 1 January 2026, bringing the euro area to 21 EU Member States. This marked the culmination of Bulgaria's path toward eurozone membership, which began with fulfilling the Maastricht convergence criteria.

Official Conversion Rate: 1.95583 Bulgarian lev (BGN) per 1 euro (EUR)

With euro adoption, the Bulgarian National Bank:

• Ceased operations as a standalone central bank for monetary policy purposes
• Became a full shareholder and constituent of the Eurosystem
• Dimitar Radev took a seat on the Governing Council of the European Central Bank (ECB)
• Completed onboarding to all TARGET Services as of 2 January 2026

Historical Monetary System: Currency Board Arrangement (1997–2026)

Prior to euro adoption, Bulgaria operated a currency board arrangement (CBA) established on 1 July 1997. Under this rigid monetary framework:

• The Bulgarian lev (BGN) was pegged irrevocably to the Deutsche Mark at a fixed rate of 1 DM = 1 BGN
• Upon the introduction of the euro, the peg was automatically adjusted to 1 EUR = 1.95583 BGN
• The currency board prohibited the central bank from issuing money beyond the amount of foreign exchange reserves
• This arrangement ensured monetary discipline and price stability during Bulgaria's transition period

What This Entity Oversees

Single Supervisory Mechanism (SSM) and ECB Oversight

Following Bulgaria's euro adoption on 1 January 2026, banking supervision in Bulgaria is now conducted under the Single Supervisory Mechanism (SSM):

Supervisory Structure:

• Significant Institutions: Directly supervised by the European Central Bank (ECB)
• Less Significant Institutions (LSIs): Supervised by the Bulgarian National Bank as the national competent authority, under ECB oversight and within the SSM framework

Key Supervisory Functions:

• Prudential supervision of credit institutions and payment institutions
• Capital and liquidity requirements (CRR/CRD V)
• Stress testing and resolution planning
• Supervision of systemic risk

Pre-SSM Framework (Prior to Euro Adoption)

Before euro adoption, the BNB served as Bulgaria's primary prudential supervisor:

• Financial Penalties: Fines up to EUR 500,000 or higher in egregious cases
• Capital and Liquidity Requirements: Elevated capital buffers for institutions with compliance gaps

Licensing and Authorization Relevance

The licensing process typically involves assessment of capital adequacy, fitness and propriety of management, business plan viability, AML/CFT compliance frameworks, and IT systems readiness.

Payments and Money Movement Relevance

Transition to Eurosystem (2026)

As of 1 January 2026, the BNB no longer conducts independent monetary policy. Monetary policy for Bulgaria is now set by the Governing Council of the European Central Bank, which includes the Governor of the BNB.

BNB's Role in the Eurosystem:

• Participation in ECB monetary policy decisions through the Governing Council
• Implementation of ECB decisions at the national level
• Management of foreign exchange reserves denominated in euros and other reserve assets
• Operation of payment and settlement systems in compliance with Eurosystem standards

Pre-Euro Currency Board Framework (1997–2025)

The currency board arrangement served as Bulgaria's nominal anchor during the transition period:

• Fixed Exchange Rate Peg: BGN 1 = DM 1 (later EUR 1.95583 post-euro introduction)
• Monetary Base Coverage: The monetary base was 100% backed by foreign exchange reserves
• Limited Discretionary Policy: The CBA constrained the BNB's ability to conduct discretionary monetary policy, limiting inflation expectations
• Reserve Requirements: Banks were required to maintain reserve requirements with the BNB, supporting monetary control transmission

TARGET Participation (Post-Euro Adoption, 2026)

Bulgaria completed onboarding to all TARGET Services effective 2 January 2026. The BNB now participates in:

TARGET-BG (Large-Value Real-Time Gross Settlement System)

• Handles real-time gross settlement of large-value payments in euros
• Provides immediate settlement finality
• Integrates with the broader Eurosystem TARGET infrastructure

EuroNCS (Euro National Clearing System)

• Clears SEPA credit transfers (SCT) and SEPA direct debits (SDD)
• Operates as a multilateral netting system for retail payments
• Processes daily batch clearing cycles for lower-value transactions

Payment System Operations

• The BNB operates the national payment infrastructure in compliance with Eurosystem standards
• Real-time settlement services via TARGET-BG
• Manages the transition from the legacy BGN payment systems to EUR-denominated systems

Legacy Payment Systems (2025 and Earlier)

Prior to euro adoption, Bulgaria operated:

• RINGS (Real-time Interbank Gross Settlement System): Handled large-value BGN transactions
• BISERA (Bulgarian Interbank Settlement and Exchange Rate Arrangement): Retail payment clearing system
• BGN Reserve Requirements System: Daily reserve requirement management

These systems were gradually phased out during Bulgaria's euro changeover period in Q4 2025 and early Q1 2026.
