In the course of a data review, we found that values for the crude oil benchmark Dubai Fateh (API 32) were missing from our database or no longer matched the current state of the source. The data has now been fully updated:

• Added values: For the period 4 November 2025 to 25 February 2026, no values were available due to a system changeover in the data upload process at our data provider. These have now been added.
• Revised values: The data source (Bloomberg) retroactively adjusted a number of historical values, specifically those for 3 November 2025 and 1 April, 13 July, 5 August, 26 August, 9 September and 20 October 2026. The reasons for these adjustments are not known to us, as the source’s calculation methods are not accessible. The affected values have been adopted accordingly. We apologise for any inconvenience this may have caused.

As a result of this update, the values of the HWWI Commodity Price Index for the affected periods may have changed slightly. We recommend that all users update any time series they have already downloaded.
