OSTTRA adds Eurex Clearing to triBalance optimisation service
02 September 2025 UK, Germany

Global post-trade solutions provider OSTTRA has added Eurex Clearing to its interest rate initial margin (IM) and capital optimisation service.
The move allows over-the-counter (OTC) derivative portfolios cleared in Eurex to be included in the OSTTRA triBalance optimisation runs, reducing counterparty risk and adding efficiencies across a firms OTC derivatives portfolio.
The addition of Eurex Clearing enhances the triBalance clearing house coverage which includes LCH, CME Clearing, and the Japan 厙惇勛圖 Clearing Corporation (JSCC).
This development allows the service to further optimise IM and capital across the major central clearing counterparties (CCPs), OSTTRA says this is crucial to the US$260 trillion interest rate swap market.
Erik Petri, head of optimisation at OSTTRA, says: This collaboration builds upon the strong relationships OSTTRA is cultivating with clearing houses and other key entities in the derivative market landscape, thereby broadening global access and efficiency for portfolio optimisation.
As we continue to integrate more CCPs into the triBalance service, our clients will see continuous gains in margin and capital optimisation results, and importantly achieve risk reduction in venues previously beyond the scope of optimisation services.
OSTTRA triBalance is compatible with every major risk margin model, including ISDA SIMM and those developed by its CCP network, the firm says.
It also offers optimisation services across a range of OTC asset classes both cleared and uncleared including interest rate products, deliverable and non-deliverable FX forwards, equity derivatives, and credit default swaps.
This coverage allows OSTTRAs clients to free up collateral and capital reserves across their entire derivatives trading business, the firm says.
Danny Chart, global product lead, OTC interest rate derivatives at Eurex Clearing, adds: In an environment of heightened market volatility, ensuring clearing members have access to risk management services like OSTTRAs triBalance is paramount.
Through this collaboration, we are empowering clearing members to shift bilateral interest rate risk into Eurex Clearing, and by doing so significantly reduce counterparty risk and enhance margin efficiency through effective netting.
