ECB Signals Future Debate on Raising Bank Reserve Requirements to Reduce Central Bank Losses
Key Takeaways
- •The ECB's current minimum reserve ratio stands at 1%, and the Eurosystem pays approximately €50 billion annually in interest on more than €2 trillion of excess liquidity held by commercial banks.
- •Raising the minimum reserve requirements could save the institution nearly €4 billion per year by shifting a larger share of bank balances into reserves that earn little or no remuneration.
- •National central banks including the Bundesbank and De Nederlandsche Bank have reported multibillion-euro losses as the cost of remunerating reserves has risen sharply while income from legacy asset-purchase programs has not kept pace.
- •The deposit facility rate was raised from -0.5% in mid-2022 to a peak of 4% by September 2023 during the bloc's most aggressive tightening cycle, before the ECB began cutting rates in June 2024.
- •A decision on whether to proceed with changes to the reserve requirement framework is expected later this year as part of a broader Eurosystem review of its operational framework.
ECB Signals Future Debate on Raising Bank Reserve Requirements to Reduce Central Bank Losses
The European Central Bank (ECB) has indicated it may open a future debate on raising minimum reserve requirements for commercial banks, a move designed to reduce the interest payments the Eurosystem makes to lenders and help address mounting losses at national central banks across the currency bloc.
Under the Eurosystem's current framework, commercial banks in the euro area are required to hold a percentage of certain liabilities—such as customer deposits—as reserves at their national central banks. The minimum reserve ratio currently stands at 1%. Reserves held above the minimum threshold are considered excess liquidity, and the ECB remunerates these balances at its deposit facility rate, which was raised from -0.5% in mid-2022 to a peak of 4% by September 2023 as part of the bloc's most aggressive tightening cycle in its history. Although the ECB began cutting rates in June 2024, the cost of remunerating reserves remains dramatically higher than during the prolonged negative-rate era that preceded tightening.
According to the report, the Eurosystem is estimated to be paying close to €50 billion per year in interest on more than €2 trillion of excess liquidity currently held by banks. Raising the minimum reserve ratio would shift a larger share of those balances into reserves that earn little or no remuneration, potentially saving the institution nearly €4 billion annually.
The proposal also takes aim at a broader problem: sustained financial losses at several national central banks within the Eurosystem. National central banks including the Bundesbank and De Nederlandsche Bank have reported multibillion-euro losses as the cost of remunerating bank reserves has risen sharply, while income from legacy asset-purchase programmes and bond holdings has not kept pace. While central banks can operate with negative equity without facing insolvency in the conventional sense—given their ability to create currency—sustained losses can eliminate or reduce annual profit distributions to national governments and may require accounting provisions against future earnings, tightening fiscal constraints on member states already navigating elevated debt levels.
The discussion also comes amid a broader Eurosystem review of its operational framework, which governs how liquidity is provided to banks and how short-term interest rates are steered. Decisions in this area have direct implications for bank profitability, lending conditions, and the transmission of monetary policy across the bloc's economies.
A decision on whether to proceed with changes to the reserve requirement framework is expected later this year, according to the report.
