Principal Protected Notes
objective
Execute principal-protected note workflows with transparent payoff decomposition, hedge diagnostics, and robust control gates.
workflow
- •define payoff terms, participation, barriers, maturity, and protection constraints.
- •decompose note value into bond floor, option sleeve, fees, and funding spread components.
- •calibrate option assumptions and hedge exposures across delta, gamma, vega, and carry.
- •stress issuer spread, volatility shocks, and liquidity slippage on projected outcomes.
- •release only when payout logic, pricing error, and hedge risk pass control limits.
required diagnostics
- •bond-floor and option-cost decomposition consistency.
- •participation-rate sensitivity to volatility and funding assumptions.
- •greek exposure concentration and hedge slippage behavior.
- •issuer-spread widening impact on note value and protection quality.
- •payout replication error across stressed paths.
risk controls
- •enforce pricing-error and hedge-slippage hard thresholds.
- •enforce issuer concentration and spread-sensitivity limits.
- •enforce fallback assumptions for illiquid strikes and tenors.
outputs
- •run
python scripts/principal_protected_notes_diagnostics.py input.csv --output diagnostics.jsonand keep the json artifact. - •write an implementation memo using
references/principal-protected-notes-playbook.mdwith assumptions, tests, limits, and rollout plan.
resources
- •use
scripts/principal_protected_notes_diagnostics.pyfor deterministic diagnostics. - •use
references/principal-protected-notes-playbook.mdfor the domain checklist and delivery structure.
