What You Can Do

You can architect and implement pricing models for vanilla and exotic derivatives, including options, swaps, and structured products. Claude helps you design Monte Carlo simulation frameworks, calibrate model parameters to market instruments, validate implementations against benchmarks, and stress-test pricing across extreme market scenarios. The result is production-ready code that passes governance checks and aligns pricing with market reality.

Features

Monte Carlo simulation design

Build efficient simulation frameworks for path-dependent and complex payoff structures

Volatility calibration

Implement calibration workflows to extract implied volatilities from market instruments

Numerical method selection

Choose and implement finite difference, binomial, or lattice methods appropriate to your derivatives

Risk-neutral valuation

Structure models using discounted expected value under risk-neutral measures

Benchmark validation

Compare model prices against market quotes, Bloomberg terminals, or vendor models to identify discrepancies

Stress-testing frameworks

Generate market scenarios and measure pricing sensitivity across interest rates, volatility, spreads, and correlations

Error handling and edge cases

Implement safeguards for pricing failures, convergence issues, and market data gaps

Example Output

Example 1: Monte Carlo Option Pricer You provide a European swaption specification. Claude generates Python code implementing:

  • Path generation for interest rate curves (Hull-White or Black-Karasinski)
  • Swaption payoff evaluation at maturity
  • Convergence diagnostics and confidence intervals
  • Comparison to market quotes from your data

Example 2: Volatility Surface Calibration You supply option market prices across strikes and tenors. Claude produces:

  • Sabr or SVI volatility surface fitting code
  • Calibration optimization (least squares minimization)
  • Interpolation methods for off-grid strikes
  • Diagnostic plots showing fit quality

Example 3: Stress-Testing Report You specify a derivatives portfolio and stress scenarios (parallel yield shift, volatility spike, correlation shock). Claude generates code that:

  • Reprice all positions under each scenario
  • Calculate P&L impacts and Greeks sensitivity
  • Identify concentration risks and tail exposures
  • Output HTML report with charts

What's Included

  • SKILL.md: Complete instructions for model architecture, calibration workflows, and validation checklist
  • Monte Carlo template: Boilerplate code structure for path generation, payoff evaluation, and convergence analysis
  • Calibration framework: Parameter fitting workflows using scipy.optimize and numerical root-finding
  • Stress-testing checklist: Scenario definitions and validation metrics for derivatives portfolios
  • Validation playbook: Step-by-step guide for benchmarking models against market data and vendor systems

Who It's For

  • Quantitative analysts building pricing models for trading desks
  • Risk managers implementing pricing validation and limit monitoring
  • Derivatives traders developing proprietary pricing frameworks
  • Financial engineers architecting pricing systems for investment banks
  • Fintech developers building derivatives pricing APIs

Best For

  • Implementing Monte Carlo simulations for path-dependent derivatives
  • Calibrating volatility surfaces and term structures to market instruments
  • Validating model prices against benchmarks and detecting arbitrage opportunities
  • Stress-testing derivatives portfolios under market scenarios
  • Debugging pricing discrepancies and troubleshooting numerical convergence issues
  • Documenting model assumptions and limitations for governance reviews
