Impact on banks and clients (Citi and peers)

How these shifts typically show up in transaction banking conversations.

Compete, partner, or adapt

Banks may compete on platform distribution and data services, partner via integrations and referral models, or adapt by improving portal visibility and onboarding experience.

Label: Analyst interpretation

What clients ask for next

More self-serve onboarding, clearer documentation, event-driven status, and reconciliation-ready identifiers and data fields.
