SWESTR

Interest rate 

SWESTR (Swedish krona Short Term Rate) is always expressed to three decimal places. Read more on the page Calculation method and transaction dataset for SWESTR.

Value day for the interest rate

SWESTR is calculated on the basis of the previous banking day’s transactions and is therefore presented with a time lag of one day. The value day is the day the rate value refers to.

Publication day

SWESTR is published at 09.00 every banking day. If transaction data is received or validated late, the Riksbank has the possibility of updating the value at 12.00 on the same day, at which point it will become the new official value. However, an update of the interest rate listing will only be made if the deviation between the interest rate published at 09.00 and the new calculated interest rate exceeds two basis points.

Volume

The total transaction volume on which the calculation of SWESTR is based.

Number of transactions

Number of underlying transactions used for the calculation of SWESTR.

Number of reporting agents

Number of reporting agents that have contributed transaction data for the calculation of SWESTR.

Upper trimming boundary

Interest rate at the upper trimming boundary, which corresponds to the volume-weighted percentile 87.5 of the transaction dataset before trimming

Lower trimming boundary

Interest rate at the lower trimming boundary, which corresponds to the volume-weighted percentile 12.5 of the transaction dataset before trimming.

Calculation method

When the transaction dataset does not fulfil one or more robustness requirements, or in the case of technical problems, SWESTR will be calculated in an alternative manner. If this is the case, the reason for the alternative calculation method will be presented.

1. Insufficient number of reporters
2. Insufficient volume
3. Excessive volume share
4. Technical problems

Value day

For average rates and index, the value day is the same as the publication day, and also the end date for the time period over which the average rates are calculated. The calculation of index values and average rates takes into account the SWESTR listing published the same day.

Index

The listing refers to the index value for the value day in question. The index reflects the cumulative return on an investment, which regularly accrues interest at the current SWESTR rate. The index is published in decimal format to eight decimal places. On 1 September 2021 the index value is 100.

Average rates

Average rates reflect the average return on an investment, which regularly accrues interest at the current SWESTR rate levels during different time periods. The average rates refer to time periods of different lengths that conclude on the value day and are published at five decimal places.

Publication day

The average rates and index are published at 09.05 every banking day. If the Riksbank publishes a corrected value for SWESTR at 12.00, the average rates and index are also corrected at 12.05.
