Real-Time Risk Assessment Engine with Typed Financial Instruments

Design a type-safe financial risk assessment microservice using TypeScript that can dynamically evaluate complex financial instruments with generics. Create a robust type hierarchy for different asset classes (bonds, derivatives, equities) that supports runtime polymorphic risk calculation. Implement a generic RiskProfile<T> type that can calculate Value at Risk (VaR) with compile-time type safety, handling different risk calculation strategies for each instrument type.
