The European Central Bank establishes transitional rules to integrate Bulgarian financial institutions into the Eurosystem's minimum reserve regime effective 1 January 2026. The decision mandates a specific maintenance period from 1 January to 10 February 2026 during which reserve bases are calculated using balance sheets from late 2025. It further permits euro-area institutions to deduct liabilities owed to Bulgarian entities during this transition to ensure smooth operational integration without disproportionate burden.
