Our MarketFX product allows you to create conversions from one currency to another at the prevailing market rate via one of our panel of global liquidity providers. MarketFX pricing is provided 24 hours a day, every day of the year to ensure you are always able to transact when you need to.

MarketFX is best suited to customers who are highly transactional and need to be booking many transactions in a short period of time at the best possible rate at the point of conversion. Typical MarketFX customers may be managing FX market risk separately, or be less sensitive to FX market risk. MarketFX is also a simpler integration than LockFX, with no additional need to retrieve and manage quotes.

MarketFX Flow

Transaction flow

The MarketFX transaction flow can be broken down into its component parts:

  1. (Optional) Retrieve an indicative price: Not all customers will need to retrieve an indicative price before placing a conversion request or a payout request with underlying conversion. For those that do, you must call Retrieve an indicative MarketFX quote API.
  2. Book a conversion request: After you retrieve the indicative price, you can choose to book a conversion request.

    You can also specify a conversion date on which the conversion will be settled to and from your Wallet. If you do not specify a date, Airwallex determines the default based on your funding mode (see settlement timing).

The variance between the price you get executed at and the indicative rate initially returned will be determined by the following criteria:

  • Market conditions
  • The amount of time you wait between calling for the indicative price and requesting a conversion

MarketFX Transaction Flow


Airwallex has integrated with several global and regional banks that provide pricing in both freely traded pairs and in currencies with additional capital controls. Our proprietary MarketFX pricing engine blends prices from across our panel of banks to generate highly available and stable FX prices accessible by clients 24 hours a day, 7 days a week.

Airwallex’s MarketFX pricing algorithm is designed to deliver the best possible price to clients at the time of execution, taking into account a wide variety of factors which may include, but not limited to, current market volatility, available liquidity in the market, the size of the transaction and the selected date you wish to settle the transaction. Any additional agreed margin will be applied on top of the price produced by our MarketFX pricing engine.
