FX Option Collar Hedge Calculator

How the FX option collar hedge scenario is calculated

A collar places a lower and upper rate around an underlying exposure by combining a long protective option with a short financing option. For a base-currency receivable, the calculator adds a long put at the lower floor and a short call at the upper cap. For a base-currency payable, it mirrors the protection: a long call limits the high-rate cost and a short put helps finance that call but gives up benefit below the lower rate.

Every rate uses quote currency per one base-currency unit. A EUR 100,000 receivable at an entered EUR/USD expiry spot of 1.05000 has an unhedged value of USD 105,000. The direct base amount is used without assuming a standard lot or exchange contract. The tool does not round the exposure into contract counts or verify whether an OTC or listed product can match that amount.

For a receivable, put intrinsic increases proceeds when expiry spot falls below the put strike, while the written call offsets proceeds above the call strike. Ignoring premiums and cost, the resulting rate is clamped between the floor and cap. Net proceeds then subtract the put premium paid, add the call premium received and subtract the entered transaction cost.

For a payable, the long call offsets unhedged cost above the call strike, while the written put removes further benefit below the put strike. Gross payable cost is therefore also clamped between the same two strikes. Net cost then adds the call premium paid, subtracts the put premium received and adds the entered transaction cost.

The premium flow is signed. A positive amount is a net debit; a negative amount is a net credit. A so-called zero-cost collar is not assumed. Even if entered option premiums offset exactly, bid-ask, commission, tax, financing, collateral and operational expenses can prevent the structure from being economically zero cost.

The all-in band spreads the entered net premium and total cost across the base exposure. For a receivable those amounts lower the net floor and cap because they reduce proceeds. For a payable they raise the net floor and cap because they increase cost. The displayed all-in scenario rate is simply net collared quote amount divided by entered base amount.

The net effect comparison is direction aware. For a receivable, positive means net collared proceeds exceed unhedged proceeds in this one scenario. For a payable, positive means net collared cost is below unhedged cost. A negative amount can be the expected trade-off from premium, cost or surrendered favorable movement; it is not automatically evidence of a defective hedge.

A real hedge decision also depends on exposure timing, certainty, cash-flow direction, option exercise style, expiry cut, settlement, premium currency, hedge accounting, credit, collateral, liquidity and provider terms. This browser calculator observes none of those facts and cannot certify effectiveness, suitability or compliance.

How to interpret the result

1. Choose receivable when you expect to receive or hold the base currency and care about its quote-currency proceeds; choose payable when you must buy or deliver the base currency.
2. Confirm the put floor is below the call cap and that both option legs match the exposure orientation, amount, expiry and settlement.
3. Read the gross protected rate before premiums and cost. Use the all-in band when comparing the economic floor and cap under the entered expense assumptions.
4. A positive net effect is scenario-specific. The opposite spot move can reveal the favorable movement surrendered to the written option.
5. Treat a net credit with caution: receiving premium does not eliminate assignment, collateral, liquidity, settlement or short-option risk.
6. Use multiple plausible expiry spots and verify actual provider specifications. The calculator neither selects strikes nor determines how much of the exposure should be hedged.

Assumptions and limitations

• No live spot, forward, option chain, bid, ask, volatility surface, account, exposure feed, order, execution, exercise, assignment or settlement system is connected.
• Only one plain-vanilla put, one plain-vanilla call and one equal base-currency exposure at the same expiry are modeled.
• The calculation is expiry-only. Before-expiry time value, volatility, rates, skew, delta and early closeout value are not calculated.
• Contract counts, lot rounding, premium currency conversion, settlement cut, holidays, deliverability and basis risk are excluded.
• Hedge accounting, effectiveness testing, tax, legal documentation, counterparty credit, collateral and regulatory treatment are outside the tool.
• Entered total cost is not a provider quote and may omit spread, slippage, commission, exercise fees, financing and operational expenses.
• No exposure direction, hedge ratio, strike, premium, expiry, zero-cost label, provider, broker, option leg, strategy or trade is recommended.
