The right to exchange currency at a strike
A forward with an escape hatch, bought for a fee. The holder may exchange two currencies at an agreed strike rate but is never forced to, so a hedger keeps protection against an adverse move while retaining the benefit of a favourable one. That asymmetry is paid for upfront in premium, which makes an option a more expensive hedge than a forward at the moment it is put on and a better one only if spot travels far enough in the hedger’s favour.

An FX option gives the holder the right, not the obligation, to buy or sell one currency for another at a set strike rate on or before expiry. The seller has the mirror position: an obligation to deliver if the holder exercises, in exchange for the premium received.
A call gives the right to buy the base currency; a put gives the right to sell it. The buyer pays a premium for this flexibility. Because every FX trade has two sides, an option is always a call on one currency and simultaneously a put on the other — the right to sell euros for dollars at 1.0800 is the same contract as the right to buy dollars with euros at that rate.
This is why FX confirmations name both legs. “A EUR put / USD call, strike 1.0800, €10m” is unambiguous; “a euro put” on its own does not say what the euro is being sold against.
Firms hedge currency exposure while retaining upside if rates move favourably — unlike a forward, which locks in the rate either way. Options also suit exposures that may not happen: a company bidding for a foreign contract would be left with an unwanted forward if the bid failed, whereas an option is simply left to lapse.
Strike, premium, expiry, notional and exercise style (European on one date, American any time before expiry). Implied volatility drives the price, and dealers hedge their delta — the option’s sensitivity to the spot rate.
The FX options market quotes in volatility rather than cash: dealers agree a vol number and the premium falls out of an agreed model, which is why the standard reference points are at-the-money vol, 25-delta risk reversals and butterflies.
The premium is a real cost, making options a more expensive hedge upfront than a forward, and it is lost if the option expires worthless. Sellers face large open-ended losses, and exotic features such as knock-out barriers can cancel a hedge exactly when it is needed most.
Premium on a vanilla FX option is normally paid two business days after the trade date — the same settlement convention as an FX spot trade.
The option floors the exporter at $21,300,000 — an effective 1.0650 — while leaving the upside open. It only beats the forward above 1.1050, the forward rate plus the 150-pip premium; anywhere below that the forward produces more dollars, and the difference is what the upside costs.
Corporates reach for options when the exposure itself is uncertain, such as a bidder for an overseas contract that would be stuck with a live forward if it lost the tender. Asset managers and hedge funds buy them for asymmetric positions around elections and central bank meetings, and dealer desks run large books of them, hedging delta continuously in the spot market and managing what is left over in volatility.
The app adds a twelve-question bank for FX Option, drawn differently every sitting, and a review queue for whatever you miss.
A subscription adds 3 further sections on FX Option — Quoted in deltas, not strikes, Which currency the premium is in, Pricing away from the quoted points — and 12 more questions to its bank.
