The Bulgarian financial market is currently navigating a period of high stability, largely driven by the strategic goal of Eurozone accession (expected January 1, 2026). The Bulgarian National Bank (BNB) has been the main source of guidance on how these major changes will affect households and existing loans.
1. The Stability of Bulgaria's Base Rate
The BNB’s Base Interest Rate (BIR) has remained stable and low, currently around 1.80% (as of November 2025). This stability is a key reason why variable mortgage rates in the country remain near historic lows ([1]).
2. No Forced Rate Changes on Existing Loans
One of the greatest fears about Eurozone entry is a sudden, compulsory increase in interest rates. The BNB Governor has directly clarified this:
The transition to the Euro will not, by itself, grant banks the right to unilaterally modify the interest rate on existing loan contracts.
Existing contracts will remain in force, with amounts simply converted to Euros (€1 = 1.95583 BGN) ([2]).
3. New Requirements to Cool the Lending Market
Despite low interest rates, the BNB has tightened lending standards in a move to prevent the real estate market from overheating:
Higher Down Payments: The maximum Loan-to-Value (LTV) ratio is now capped at 85%. Income Limits: Debt-Service-to-Income (DSTI) ratio is capped at 50%. Maximum Term: The loan term is now limited to 30 years ([3]).
