Euro Overnight Index Average (EONIA)
The Euro Overnight Index Average (EONIA) is the average overnight reference rate for which European banks lend to one another in euros. If you ever wondered how banks manage to keep lending to each other through the night, EONIA is the secret sauce. It’s like a sleepover for banks—everyone promises to pay back by the morning!
Definition
EONIA represents the interest rate applied to overnight loans between European banks. This rate is calculated by the European Central Bank (ECB) and is based on the loans made by 28 different panel banks. However, EONIA has taken a backseat since January 2022, being replaced by the more robust Euro Short-Term Rate (ESTER) due to regulatory reforms.
| EONIA | ESTER |
|---|---|
| Average overnight rate for interbank loans | More comprehensive, capturing all overnight unsecured transactions |
| Calculated by ECB | Also calculated by ECB, but with broader scope |
| Based on 28 panel banks’ transactions | Based on a larger sample of banks |
| Implemented until December 2021 | Effective from January 2022 |
How EONIA Works
To explain how EONIA functions, consider that it collects data on overnight loans between banks and calculates a weighted average based on the size of the loans, ensuring that whispers of borrowing rates don’t overnight become only a dream.
