British Pound Options (GBP/USD)

What the call and put give you

A call locks in the right to buy GBP at the strike exchange rate. A put locks in the right to sell it there. Paying the premium gives the buyer a choice; it does not oblige the buyer to exercise.

All example rates are USD per GBP. A higher rate means a stronger GBP.

The example trade

Assume the underlying starts at 1.25 USD per GBP. One option has a strike of 1.25, a premium of 0.02 and a multiplier of 100,000. The total premium is USD 2,000. Prices and premiums are hypothetical; the call and put use equal premiums to make the comparison easy.

The following results are at expiration, before fees. If exercise creates another position, the calculations assume that position is immediately closed at the stated value.

Buying GBP calls

You buy the call because you expect the underlying price to rise. At 1.3 USD per GBP, the right at the strike is worth (1.3 − 1.25) × 100,000 = USD 5,000. After the premium, your profit is USD 3,000.

At 1.25 or below, the call expires without intrinsic value and loses its USD 2,000 premium. Its expiration breakeven is 1.27 USD per GBP. At 1.26, the price has risen but the trade still loses USD 1,000.

Buying GBP puts

If you expect a fall instead, the put costs USD 2,000 in this example. At 1.2 USD per GBP, it is worth (1.25 − 1.2) × 100,000 = USD 5,000. Your profit is USD 3,000 after the premium.

At 1.25 or above, the put loses its entire premium. Its expiration breakeven is 1.23 USD per GBP. A smaller fall to 1.24 still leaves a loss of USD 1,000.

Before expiration

You can sell an option to close when a market is available. Its resale value also depends on time remaining and implied volatility, so the expiration breakevens do not determine every earlier trading result.

The purchased option can lose its full premium. Exercise may create a separate position or funding obligation. Selling an uncovered option can produce losses larger than the premium received.
