€STR

The Euro Short-Term Rate (€STR) is a

EONIA) as the Euro risk-free rate for all products and contracts.^[1]

History

20 September 2017: ECB's Governing Council decided to develop a euro short-term rate based on data collected by the Eurosystem for money market statistical purposes.[2]

13 September 2018: the working group on euro risk-free rates recommended to replace the

EONIA with the euro short-term rate.^[3]

12 March 2019: the ECB decided to use the acronym “€STR“.[4]

2 October 2019: the ECB started to publishing the rate.^[5]

Characteristics

Characteristics of the €STR:^[2]

The €STR is published by the ECB.
It is based on the unsecured market segment. The ECB developed an unsecured rate to replace EONIA. Furthermore, a secured rate would be affected by the type of the collaterals.
The money market statistical reporting covers the 50 largest banks in the euro area in terms of balance sheet size.
While EONIA reflected the interbank market, €STR extends the scope to money market funds, insurance companies and other financial corporations because banks developed significant money market activity with those entities.

The

ISIN is EU000A2X2A25.^[6]

Methodology

Overnight rate

The €STR is calculated using overnight unsecured fixed rate deposit transactions above €1 million.[2]

For each TARGET2 business day the €STR is calculated as a volume-weighted trimmed mean.

Steps of the calculation:^[2]

Ordering the transactions from the lowest rate to the highest rate.
Aggregating the transactions at each rate level.
Removing the top and bottom 25% in volume terms (trimming).
Calculating the mean of the remaining 50% and rounding to the third decimal.

The €STR is published on every TARGET2 business day at 8:00 CET (reflecting the trading activity of the previous business day). If errors are detected, the €STR is revised and republished on the same day at 9:00 CET.^[7]

Forward-looking term structure

An OIS quotes-based methodology as the €STR-based forward-looking term structure methodology is recommended as a fallback to Euribor-linked contracts. The working group will analyse further approaches.^[8]
