How would you design a layered (rolling) hedging program for recurring forecast FX exposures, and why layer rather than hedge spot-by-spot?
A core Corporate Treasury interview question — asked in analyst and associate interviews across IB, PE, and the Big 4.
THE SHORT ANSWER
A layered program hedges a declining percentage of exposure further out — e.g., 80% of the next quarter, 60% of the following, tapering to 20% twelve-plus months out — and rolls forward each period. Layering smooths the effective rate over time, so no single bad rate at one execution date dominates results, and it avoids trying to time the market. It also matches hedge certainty to forecast certainty: near-term volumes are reliable, far-term aren't, so you hedge less of what you're less sure about. The rules are set in policy (tenors, ratios, instruments) so execution is disciplined and auditable, and effectiveness is reviewed as forecasts firm up.
WHAT INTERVIEWERS LISTEN FOR
- ✓Declining hedge ratio by tenor, rolled each period
- ✓Smooths the achieved rate, avoids single-point timing

- ✓Policy-driven ratios/tenors for discipline
COMMON MISTAKES
- ✗Hedging 100% of uncertain far-dated forecasts
- ✗Ad hoc, market-timing execution
- ✗No policy framework
