Santander acquired a stake in the capital of CACEIS at the end of 2019 and contributed its asset servicing and institutional custody activities in Spain and Latin America (Brazil, Mexico and Colombia) to CACEIS. This transaction has brought together CACEIS and Santander Securities Services (S3) to create a leading global player serving international institutional clients.
On July 3, 2023, CACEIS completed the acquisition of RBC Investor Services Bank S.A. activities in Europe and Malaysia, which have been rebranded CACEIS Investor Services Bank S.A.
