A RIX participant must pay fees to the Riksbank in accordance with the price list applied by the Bank. Fees are set on the principles of cost coverage and non-discrimination and are designed to promote the use of RIX for the gross settlement of large payment commitments. The fees are made up of a fixed and a variable portion. The Riksbank may charge a RIX participant for development costs in connection with accession to RIX or the development of new services or for other costs not included in the basis for fee-setting.
