Interbank Rate / Overnight Rate (EUR)

The rate banks charge each other for overnight lending (e.g., SOFR, €STR, SONIA). This rate closely tracks the Central Bank's policy rate and reflects immediate liquidity conditions in the money market. Deviations from the policy rate can signal unexpected stress or excess liquidity, providing real-time insight into the Central Bank's operations.
