Provable Markets, provider of securities finance platform Aurora, has announced the release of its updated FIX specification and FIX Engine.
The move follows the FIX Trading Community鈥檚 revised best practices for securities lending orders and execution workflows.
The updates are in support of Aurora鈥檚 Marketplace Product, building upon the firm鈥檚 FIX specification first released in 2022.
Provable Markets 鈥� a member of the FIX Trading Committee and its Securities Lending Working Group 鈥� will look to onboard third-party vendors and clients to the updated interface in the first quarter of 2026.
The FIX Trading Community鈥檚 initiative aims to unify trade execution practices and introduce open-source FIX Protocol benefits to a previously underserved area of capital markets.
The current market environment 鈥� characterised by proprietary solutions and inconsistent processes 鈥� forces firms to undertake costly custom development and budget separately for each vendor, partner, or counterparty integration, says Provable Markets.
Commenting on the proposed guidelines, Rachel Andreassian, head of product and market structure at Provable Markets, says: 鈥淎s a service provider to some of the top securities finance institutions, I鈥檓 excited to be part of the team that is introducing FIX to a market that can greatly benefit from a common language.
鈥淏y lowering the complexity and costs that typically come with integrating and automating, participants can feel more confident in adding new solutions and providers, allowing them to grow their businesses.鈥�
Alec Rhodes, vice president of client solutions at Provable Markets, adds: 鈥淭his fantastic enhancement helps the team at Provable continue to deliver on our pledge to offer universal and agnostic connectivity solutions to maximise our client鈥檚 ability to interact with the broader securities finance ecosystem鈥�.
