What are FX options?
FX options (or Forex options) are a type of derivative instrument that gives the holder the right, but not the obligation, to exchange money denominated in one currency into another currency at a pre-agreed exchange rate on a specified date.
There are two types of options: call options and put options. A call option gives the holder the right to buy a currency pair at a specific rate on a certain date, while a put option gives the holder the right to sell a currency pair at a specific rate on a certain date.
What are the risks when trading FX options?
When trading FX options, it’s important to be aware of the potential risks. These include:
- Market risk: FX option prices are subject to fluctuations, and traders may experience losses due to adverse movements in exchange rates. FX markets can be volatile, leading to sudden and significant price swings.
- Liquidity risk: During periods of high volatility – or when trading less frequently traded FX options – there could be difficulty in executing trades or obtaining favourable prices due to limited market depth.
- Counterparty risk: When dealing with other market participants, such as brokers or financial institutions, there is a risk that the counterparty may default on its obligations, leading to losses.
Other risks when trading FX vanilla options include regulatory risks related to changes in regulations that can impact trading conditions; operational risks, involving potential issues with trading platforms, execution, or trade settlement; and systemic risks, which can affect the entire financial system, such as global economic crises.
How much can you lose trading FX options?
When buying an FX option, losses are limited to the premium paid. However, when selling (writing) an FX option, if the market moves significantly against your position, losses can be unlimited. Since options allow you to control a larger position with a smaller investment, the potential losses are magnified compared to trading the underlying asset directly.
Trading FX options with leverage
FX options are traded with leverage at Saxo, which allows you to obtain a larger exposure with a smaller investment. For example, instead of buying 100,000 Euro versus US dollar you can buy a call option that that provides the same exposure for a fraction of the cash/collateral. It’s important to be aware that while leverage can magnify profits, it can also amplify losses.
Various factors can drive price movements in FX options, including the price and volatility of the underlying currency pair, the time remaining until the option expires, and the interest rate differential between the two currencies.
For example, let’s say that you purchase a EURUSD call option. The option gives you the right to buy EURUSD at a strike price of 1.20 on the expiry date. If the actual exchange rate on the expiry date is 1.25, you can exercise the option to buy EURUSD at 1.20 – as that price is lower than the current market price, you would make a profit on the trade.
When trading with leverage, it's crucial to consistently meet margin requirements to avoid a stop-out/margin call. Read more: What is initial and maintenance margin?
Settlement types
The settlement type describes how an options contract is settled between the parties when it is exercised. With SaxoTrader, you can choose the settlement style to apply to your FX options if they end up in-the-money.
Current settlement choices:
- Spot
- Cash
New settlement choices from 21-09-2026:
- Spot
- Close at market
Physical spot
Upon expiration, converting an option into an FX spot position means you effectively establish a spot trade based on the option's parameters. This leads to holding the currency pair specified by the option, such as EURUSD, either long or short.
Close at market
Under the Close at market settlement type, any position arising from an option exercise is automatically closed via a market order.
- The option exercise creates an FX spot position at the strike price.
- This spot position is immediately closed at the prevailing market (bid/ask) price.
- The resulting FX spot positions are related and netted at end of day (EOD).
- The cash credited to or debited from your account reflects the difference between the strike price and the applicable market rate at the time of execution.
Example
You hold a call option on EURUSD, strike 1.2. On the expiry date at cut-off, EURUSD is fixed at 1.449. Therefore, the option is auto exercised, and the exercise creates a spot position at the strike price. If you have chosen “close at market”, the system closes this position using a market order at the current market price (bid/ask). The difference between the two prices is reflected as a cash amount credited to or debited from your account. The two positions are related and netted at end of day (EOD).
Cash settlement (prior to 21-09-2026)
Upon expiration, if your option is in-the-money, the settlement involves receiving a cash payment equivalent to the profit from the difference between the market exchange rate and the strike price of your option.
The cash settled exercise method is available on both long and short positions and will always be executed at the mid-price of the best bid/offer spread. This applies even in volatile market conditions.
Prior to 21-09-2026:
Settlement methods available at trade entry include “spot” (physical settlement) or “cash”. From 21-09-2026, the cash settlement method will be replaced by “close at market”.
If you place a trade while “cash” is still shown as a settlement method in the platform and you select “cash”, the method applied at expiry will depend on the FX option’s expiry date:
- If your FX option expires before 21-09-2026, it will be settled using the “cash” method.
- If your FX option expires on or after 21-09-2026, it will be automatically closed at market instead.

What are the option greeks?
Option greeks are used to measure the sensitivity of an option's price and can help understand the risk and potential reward of an option. Before placing a trade, you can view the option greeks on the trade ticket and in the FX option chain. For existing positions, you can view them in the positions module.
