Incompatibility of SWIFTNet Certificate Authority certificates and T2S

16.03.2020

A backward incompatibility between the latest version of the SWIFTNet Certificate Authority certificates and T2S could cause the rejection of the messages sent by T2S customers with reason code “CSA010-Digital signature is not valid for the Business Sending User” for those customers who renewed their SWIFT certificates with the latest SWIFTNet Certificate Authority. Customers impacted by this issue need to contact the SWIFT support. Those institutions that have not migrated to the new certificates should not upgrade until further notice.
