Citi Investor Services has rolled out Financial Information eXchange (FIX) API connectivity for its Asia Pacific exchange-traded fund (ETF) clients. The tool integrates directly into Advanced Citi ETF System (ACES), which is the bank’s global proprietary platform. The integration starts operational delivery in Australia with plans to launch the electronic messaging service in Hong Kong later this year following an earlier rollout in the United States.
The integration allows Authorized Participants (APs) to link directly into the ACES setup to handle primary market creations, redemptions and standard ETF order placements. The move utilises the FIX protocol, a global messaging standard for real-time transactional data exchange. Regional market participants are adopting this protocol at a higher rate to boost straight-through processing. A dedicated FIX working group is currently establishing structural guidelines to automate the wider ETF lifecycle beyond initial creation and redemption workflows.
Peggy Vena, Head of ETF Services at Citi Investor Services, said, “The ETF sector globally, including in Asia Pacific, continues to see significant growth. To service these increasing flows, digitization is critical for speed, efficiency and standardization. Extending FIX API connectivity to Asia Pacific demonstrates our continued commitment to investing in our platform and ETF Servicing business to benefit clients and the broader ecosystem.”
The technology upgrade automates creation baskets using direct accounting records and index provider data feeds. This setup removes the requirement for Authorized Participants to manage separate operational platforms across different stages of the asset management lifecycle. The investment follows recent financial disclosures from the company’s Investor Day, where executives identified cost-efficient corporate structures as a key area of operational growth.
The expansion comes as ETF industry assets in the Asia Pacific region, excluding Japan, reached a record 1.81 trillion US dollars at the end of February 2026. Financial models indicate the regional sector could reach between 3 trillion and 3.5 trillion US dollars by 2029. Structurally, the bank’s wider custody business reported over 31 trillion US dollars in Assets under Custody and Administration during the first quarter of 2026, supported by new global service mandates across multiple geographic regions over the last year.
