What is an FX Spot Transaction?
The simplest way to exchange currencies at today’s rate
Expert guides
Posted on:
An FX spot transaction (also called a foreign exchange spot) is the simplest and fastest way to exchange currencies. It means converting one currency into another at the current market rate (spot rate) the moment you execute the transaction.
In practice, this is the type of foreign exchange most companies use for everyday international payments.
If you need to pay a supplier abroad, settle an invoice in another currency, or convert incoming funds, you are most likely using a spot FX transaction.
What defines a spot transaction is its immediacy. It is used when the need to exchange currency is urgent or near-term, without planning for a future date or using more complex structures.
The exchange rate is fixed at execution, not at settlement
When you execute a spot FX transaction, the exchange rate is confirmed at that moment.
Even though settlement typically takes place within two business days, the rate does not change after execution. From that point on, your transaction is no longer exposed to market movements.
When companies use spot FX transactions
Spot transactions are designed for the following situations:
pay an international supplier or partner now or within the next few days
convert incoming funds as they are received
execute a payment without planning or hedging for a future date
For most businesses, spot FX transactions are part of everyday operations. They are quick to execute and do not require any long-term commitment.
Spot FX transaction example (CHF to CNH)
Let’s say your company needs to pay a supplier in China, but your funds are in CHF.
To complete the payment, you execute a CHF → CNH spot FX transaction.
You are shown a live exchange rate
You confirm the trade and the rate is locked
The CNH amount is sent to your supplier, typically within one to two business days
From that point on, your cost is fixed, regardless of how the market moves.
What is the difference between spot and forward FX?
The key difference between a spot transaction and an FX forward is when the transaction takes place.
We use a spot transaction when there is no need to plan ahead and a forward contract is used when the exchange is planned in advance.
Spot → you exchange currency at the current market rate
Forward → you lock an exchange rate today for a future date
For example, if you know you’ll need to pay a supplier in three months, a forward allows you to secure today’s rate and avoid uncertainty from future exchange rate movements.
Spot FX risk comes from movements before execution
Spot FX transactions themselves are simple, but timing is critical.
The main risk comes from exchange rate movements before you execute the trade. If the market moves between the moment you agree on a price with your supplier and when you make the payment, your costs can change.
This is where many companies face budgeting discrepancies, especially when payments are not executed immediately.
Once the spot transaction is executed, however, the rate is fixed and there is no further exposure to market movements.
