Euro area banks adjust to declining reserves, preparing for increased ECB operations

Central bank reserves in the Eurosystem have almost halved from a peak of €4.9 trillion in 2022 to €2.6 trillion in early 2026.

While still abundant, these reserves are unevenly spread across banks, implying some institutions may need to source liquidity sooner than others.

Money market rates have concurrently moved closer to the deposit facility rate (DFR), the ECB's main policy rate.

An annual Eurosystem survey reveals that banks representing 26 percent of all euro area banking assets now operate close to their preferred reserve levels, up from 15 percent a year earlier.

This group includes large, globally systemically important banks (G-SIBs), as well as custodians and asset managers, who generally manage their liquidity more actively.

Reserves are projected to decline by about €470 billion per year, with banks accounting for 50 percent of total banking assets expected to reach their preferred level by the end of 2026, necessitating more active liquidity management.

Euro area banks are actively managing liquidity through money markets, ensuring smooth redistribution of central bank reserves without fragmentation.

The repo market, a key channel for borrowing and lending reserves, sees increased participation from banks nearing their preferred reserve levels.

Term money markets are also vital for Basel III regulatory compliance, specifically the liquidity coverage ratio (LCR) and net stable funding ratio (NSFR), with rising premia signaling system-wide liquidity needs.

Short-term market interest rates, including the euro short-term rate (€STR) and secured repo rates, remain close to the ECB's deposit facility rate (DFR).

This indicates stable funding conditions despite declining reserves.
