Despite its benefits, downstream banking has historically carried negative connotations within parts of the financial industry. The concern has largely centered on transparency: when multiple institutions sit between the originating bank and the correspondent account, it can become harder for the correspondent bank to see who is ultimately accessing their services. If not carefully managed, these additional layers of intermediation can reduce visibility into the underlying institutions or customers involved in a transaction. Over the past 10 years, however, this issue has evolved along with industry standards and compliance-related investments.
Regulatory expectations around financial crime prevention – including principles such as beneficial ownership transparency, suspicious activity reporting and sanctions compliance – have become more consistent across major jurisdictions. In parallel, industry initiatives have helped standardise due diligence practices across correspondent banking relationships.
Among these is the Wolfsberg Group’s Correspondent Banking Due Diligence Questionnaire (DDQ).1 Produced by the Basel-based Wolfsberg Group, an association of 12 major banks tasked with developing frameworks and guidance for the management of financial crime risks, the DDQ provides a common framework for banks to disclose and assess their compliance controls. Covering areas such as anti-money laundering governance, sanctions controls, transaction monitoring frameworks and internal compliance structures, the Questionnaire enables institutions to demonstrate that they meet the baseline standards required to participate in correspondent banking networks.
These transparency expectations also extend beyond the onboarding stage. Regulators expect banks to review downstream relationships on an ongoing basis, assess the risk profile of downstream institutions and ensure that respondent banks maintain robust due diligence programmes for their own customers. Correspondent banks support this oversight through advanced transaction monitoring, behavioural analytics and network-level surveillance, allowing unusual activity to be identified through patterns that may not be visible within a single institution.
An additional factor is that payment infrastructures have become increasingly digitalised and standardised, so the amount and quality of information available to institutions processing cross-border payments has increased substantially. For example, the November 20252 full adoption of ISO 20022 – the global messaging standard for cross-border payments – enables banks to capture richer and more consistent payment data, improving the identification of all parties involved in a transaction and strengthening screening and monitoring capabilities.
Taken together, these developments have created a more transparent and interconnected correspondent banking ecosystem, enabling institutions to manage downstream relationships with greater visibility and confidence than before.
