When necessary, a corrected reference rate will be published

The Riksbank publishes SWESTR at 11.00 each banking day. If any reporting agency or agencies send in or validate transaction data too late, so that it is not received by the first calculation, the Riksbank can publish a corrected value for SWESTR at 14.00 on the same day. A correction is also a possibility in the case of technical problems. This value then replaces the previously published one as the official value for SWESTR. A corrected interest rate will only be published if a new calculation gives rise to an interest rate that deviates by more than two basis points from the value published at 11.00.

A revised historical data series will be published with a time lag

In addition, the Riksbank will publish a revised historical data series for SWESTR that takes into account all of the revisions to transaction data, regardless of when they are made. This is published with a time lag. The reason why the Riksbank has chosen to publish a revised historical time series is that the Riksbank wishes to be transparent and to allow assessments to be made of SWESTR and its underlying processes. However, the revised time series does not affect the official history for SWESTR. The value published on the original publication day – and, where appropriate, the corrected value published at 14.00 – remains as the official value for SWESTR.
