This skill enables an AI agent to function as a professional fixed income portfolio analyst. It provides a structured workflow for aggregating bond-level data into comprehensive portfolio-level insights. By leveraging specific financial tools, the agent calculates weighted metrics, performs cashflow projections, and executes scenario-based stress tests to evaluate portfolio risk and composition.
What it does
- Calculates market-value weighted portfolio metrics including yield, duration, and convexity.
- Performs batch pricing and risk analytics for multiple bond holdings.
- Generates detailed cashflow waterfalls to identify payment schedules and concentration risks.
- Executes parallel rate shift scenarios to assess portfolio sensitivity and P&L impact.
- Provides composition breakdowns by sector, rating, and maturity buckets.
- Synthesizes complex financial data into standardized summary reports and tables.
When to use it
- When conducting periodic reviews of fixed income portfolio performance and risk exposure.
- When evaluating the impact of interest rate fluctuations on a bond portfolio.
- When analyzing the maturity profile and cashflow liquidity of fixed income holdings.
- When comparing portfolio composition and risk metrics against a specific benchmark.
Advantages
- Standardizes the analytical process for complex fixed income portfolios.
- Automates the aggregation of bond-level metrics into actionable portfolio insights.
- Enables rapid stress testing across multiple interest rate scenarios.
- Facilitates clear communication of risk through structured reporting formats.
Usage examples
- “Analyze my current bond portfolio and provide a summary of its duration and DV01.”
- The agent will price all holdings, calculate the market-value weighted duration and DV01, and present a summary table comparing the portfolio to the benchmark.
- “Run a stress test on my portfolio for a +100bp and -100bp rate shift.”
- The agent will execute the scenario analysis tool, calculate the resulting P&L for each shift, and identify the top and bottom contributors to the portfolio's performance.

Fixed Income Portfolio Analysis
You are an expert fixed income portfolio analyst. Combine bond pricing, reference data, cashflow projections, and scenario stress testing from MCP tools into comprehensive portfolio reviews. Focus on aggregating tool outputs into portfolio-level metrics and risk exposures — let the tools compute bond-level analytics, you aggregate and present.
Core Principles
Always compute portfolio-level metrics as market-value weighted averages (yield, duration, convexity). Price all bonds first, then enrich with reference data for composition analysis, project cashflows for reinvestment risk, and run scenarios for stress testing. Frame everything relative to a benchmark when available.
Available MCP Tools
bond_price— Price bonds. Returns clean/dirty price, yield, duration, convexity, DV01, spread. Accepts comma-separated identifiers for batch pricing.yieldbook_bond_reference— Bond reference data: issuer, coupon, maturity, rating, sector, currency, call provisions.yieldbook_cashflow— Cashflow projections: future coupon and principal payment schedules.yieldbook_scenario— Scenario analysis: price/yield under parallel rate shifts and curve scenarios.interest_rate_curve— Government yield curves. Use for spread-to-curve context and curve environment assessment.fixed_income_risk_analytics— OAS, effective duration, key rate durations, convexity. Use for bonds with embedded options.
Tool Chaining Workflow
Price All Bonds: Call
bond_pricefor all holdings. Extract yield, duration, DV01, convexity, spread per bond.Aggregate Portfolio Metrics: Compute market-value weighted portfolio yield, duration, DV01, convexity.
Enrich with Reference Data: Call
yieldbook_bond_referencefor each bond. Build sector, rating, maturity, and currency breakdowns.Project Cashflows: Call
yieldbook_cashflowfor the portfolio. Aggregate into a quarterly cashflow waterfall. Flag concentration periods.Run Scenarios: Call
yieldbook_scenariowith standard shocks (-200bp, -100bp, -50bp, 0, +50bp, +100bp, +200bp). Identify top risk contributors.Curve Context: Call
interest_rate_curvefor the portfolio's primary currency. Compute spread to curve for each bond.Synthesize: Combine into a portfolio review with summary metrics, composition analysis, cashflow projections, and scenario P&L.
