Our team combines deep, front-line experience across derivatives markets, XVA, collateral, and post-crisis regulatory frameworks — spanning both buy-side and sell-side perspectives. We do not approach this as advisors observing the market; we have built, run, and priced within it.

Collectively, we have:

  • Managed and priced complex, large-scale derivatives portfolios within global financial institutions
  • Built and led XVA, funding, and capital frameworks from the ground up
  • Designed and implemented infrastructure for counterparty risk, collateral, and balance sheet optimisation
  • Worked directly with trading desks, treasury, risk, and regulators on margining, clearing, and capital regimes

We have been directly involved in:

  • The transition to collateralised trading and the design and negotiation of CSA frameworks
  • The integration of CVA, FVA, and KVA into pricing and risk management
  • The implementation of clearing mandates, margin rules (VM/IM), and capital frameworks (Basel III/IV)
  • The practical interaction between legal terms, pricing models, and operational processes

This experience allows us to:

  • Connect pricing, funding, capital, and collateral into a single, coherent framework
  • Translate theoretical value into realised P&L and balance sheet benefit
  • Bridge front-office intent with risk, treasury, legal, and operational constraints
  • Deliver solutions that are not just optimal in theory, but executable in practice

The result is a perspective that is both technically rigorous and commercially grounded — focused on outcomes, not analysis.
