When complexity and consequence demand definitive expertise
Capital Market Risk Advisors (CMRA) is a boutique expert witness and risk advisory firm whose principals were pioneers in derivatives and major participants in complex financial markets. Founded by Leslie Rahl — derivatives pioneer, ISDA founding board member, and former Risk Committee Chair at Fannie Mae and CIBC — and led alongside Partner Peter Niculescu, former EVP and CIO of Fannie Mae’s $950+ billion portfolio and Goldman Sachs Managing Director, CMRA brings firsthand practitioner experience to every engagement.
CMRA has been involved in virtually every major derivatives and structured finance crisis since the mid-1980s, including Orange County, Bankers Trust, Sumitomo Copper, LTCM, Lehman, subprime, Madoff, Volmageddon, COVID, Allianz Structured Alpha, Texas Storm Uri and beyond. Our partners have provided expert and consulting services in over 100 disputes and testified in courts across 4 jurisdictions.
Our practice is deliberately balanced between litigation and proactive risk advisory — the same expertise that helps clients avoid problems informs our work when problems require resolution in court. Our litigation insights inform our risk advisory and risk mitigation work.
We specialize in derivatives (OTC and exchange-traded), structured finance, RMBS, CDOs/CLOs, hedge fund strategies, volatility products, commodities, energy and complex valuations. We are equally fluent in the language of quants, the language of the court, and the language of the boardroom.

Best Practices in Risk Management, Measurement, Governance and Oversight
CMRA has been at the forefront of the development of best practices in risk, establishing standards and criteria for the implementation of policies and procedures.
Effective risk management across an enterprise requires precise quantification of risk using state-of-the-art modeling, qualitative assessment of risks that cannot be fully quantified, and an effective governance, oversight and escalation structure.
Risk organizations increasingly report to a CRO who is integrated into business strategy, but the most effective Enterprise Risk Management programs are customized to the individual institution rather than imposed as a single standard model.
CMRA’s approach combines practical experience with analytically robust risk measurement. Experience gained from diagnosing and remediating financial-sector failures informs our proactive risk-management work.
