Bond Ladder Builder

Builds a target-weight bond ladder: a total notional split across maturity rungs, each rung priced as an even-period bullet bond. Reports per-rung price, Macaulay and modified duration, DV01 and convexity, plus the weight-weighted portfolio aggregates, and names every reinvestment assumption in plain sentences: hold coupons and maturing principal as cash at 0%, or roll them into the longest rung's yield. Rung weights must sum to 1 within 1e-9 or the tool refuses, naming the sum.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `build_bond_ladder`. Task: Build a target-weight bond ladder and reports rung-by-rung and portfolio duration, DV01 and convexity, with every reinvestment assumption named in plain sentences.
Call it with arguments: {"policy_parameters":{"notional":100000,"periods_per_year":2,"reinvestment_assumption":"hold_to_maturity","rungs":[{"maturity_years":5,"coupon_rate_pct":4.5,"yield_pct":4.2,"target_weight":1}]}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string, or re-run the in-page WebMCP tool `build_bond_ladder`.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
