7.1 FX Scope
The Scope of FpML 5.3 Last Call Working Draft includes redesigned FX product model developed by the Modeling Task Force (MTF) and FX Working Group to make it more consistent with other FpML product representations and to facilitate its further development. As a result of this work many of an original 4.x model’s issues were addressed:
- A number of sets of reusable components that facilitates product development were defined, so that the existing and future FX products will leverage these building blocks to ensure the FX model is coherent and easy to maintain, as per FpML best practices
- Extended the existing coverage to include Dual Currency Deposits.
- Rationalized the models' constraints:
- Made use of grammar to bring related data together.
- Made better use of XML schema to simplify the validation rules.
In FpML 5.3 Last Call Working Draft the following FX products are covered:
- Basic FX Products
- In Transparency view, FX Spot and FX Forward (in deliverable currencies only)
- FX Swap
- Simple FX Option Products (including, features, cash and physical settlement)
- FX options
- European and American
- FX options
Foreign exchange single-legged instruments include spot and forwards. fxSingleLeg contains a reusable entity (FxCoreDetails.Model) that describes common components to FX spot, forward and swap legs: two instances of the exchangedCurrency component (the first currency and the second currency), an optional dealtCurrency that indicates which currency was dealt, either a single value date component for the trade or an optional value date per exchanged currency, an optional tenorPeriod that (appears in the Reporting View only) denotes the tenor on which both currencies traded will settle, a single instance of the exchangeRate component, and an optional nonDeliverableSettlement component. Note: An optional confirmationSenderPartyReference (to the party that is sending the current document as a confirmation of the trade is accommodated) has been moved out from the product economics. It will be placed at the trade level.

The simple FX transaction contains two currencies which are exchanged between parties. The characteristics of each currency exchange: the currency, the amount, and optionally settlement instructions are described in the exchangedCurrency structure. An optional payment date is allowed per currency if there is a requirement to provide for date adjustments for each currency based upon business day conventions to accommodate unscheduled holidays.

The rate of exchange is required for a foreign exchange trade. The rate of exchange includes a reusable entity (QuotedCurrencyPair) that describes the underlying composition of the rate: the currencies and the method in which the rate is quoted. The actual trade rate is required, but other rate information such as spot rate, forward points and point value are also accommodated. For non-base currency trades, cross rates (or rates to base) to accommodate the currency exchange rates to cross between the traded currencies are provided for. Note: the refactored rate of exchange model has stricter grammar than FpML 4.x, which eliminates a few rules (e.g. fx-1, fx-2, fx-3, fx-28, fx-29 ).

A foreign exchange swap is a single product that combines two trades, either spot/forward or forward/forward. (The FpML 4.x model allowed any number of exchanges but the new restricts it to just two. In the old model FX Swap was a container for other products – like a strategy. In the new model it's a single product). A standard FX swap contains only two legs, nearLeg and farLeg to indicate the value date order. There are a variety of different types of FX swaps in the marketplace: standard (round-amount) swaps, overnight swaps, unequal-sided swaps, forward-forward swaps. All of the features that are available within FxCoreDetails.Model, common components to standard FX spot and forward trades (described previously) can be utilized in describing an FX swap as well.

Near and far legs are based on a new FxSwapLeg type and derived from a super type Leg from which all swap legs are extended (and is not derived from Product as in 4.x).
Foreign exchange options model is completely redesigned compared to 4.x model that was very loose with too many independent optional elements. It did not enforce relationships between elements. The basic data types used for values like rates had no constraints (e.g. could be negative). The model is designed to bring related data together and many elements were renamed in line with FpML naming convention and MTF recommendations.
Foreign exchange options are now more consistent with other option products. FxOption type extends new Option base type - a type that defining the common features of options - buyer and seller model and derived from a Product type (the Option type could be used to re-factor other option types). It also includes separate exercise structures for standard European and American options.
A vanilla fxOption identifies an exercise style, the put currency and amount, and call currency and amount, strike price and premium information. The premium is structured similar to an exchanged currency for a conventional FX trade, where optional settlement information for the premium can be attached. In addition, there are optional procedures associated with the exercise, a soldAs reference to allow buyer/seller perspective to be easier to derive – did I buy a put or sell a call, spotRate that this represents the current market rate for a particular currency pair. Note: quotedAs component has been removed as it was a legacy element carried through the versions and the group felt it was confusing.

7.4.2.1 American Exercise
Fx American Exercise structure includes additional support for multipleExercise with optional limits on the notional size.

One or more financial instruments, of any sort that are supported by the FpML specification, can be combined to form what is called a strategy. This can include various packages of the same or different asset classes in a single trade. Typical examples of this would include option packages (e.g., straddles, strangles) or a delta hedge (FX OTC option with spot risk hedged by FX spot deal). Additionally, other asset classes can be combined in a strategy (e.g., interest rate swap with FX, etc.).
