In this compelling episode of Ahead of the Curve, Roland Stamm is joined by Maeve Gear from FMS-SG to explore the intricate world of winding down complex financial portfolios in the wake of the global financial crisis. Together, they reflect on their shared history at Depfa Bank, the impact of the Lehman collapse, and the regulatory shifts that followed—including the rise of central clearing and the introduction of the Uncleared Margin Rules (UMR).  The conversation dives deep into the challenges of managing long-dated, illiquid, and structured trades, and how FMS-SG leverages the Open Source Risk Engine (ORE) to meet valuation, risk, and collateral management demands. Maeve shares insights into the technical and modelling hurdles her team faces, and how ORE’s transparency, flexibility, and cost-efficiency have empowered them to streamline operations and maintain high standards.  Whether you're a risk professional, quant, or simply curious about how open-source tools are transforming financial infrastructure, this episode offers a rare behind-the-scenes look at innovation in action.
