Create saccr Object and Compute Regulatory Values for Forward FX Swap

Open Live Script

This example shows how to create a saccr object for a trade involving a EUR/GBP forward FX swap with trade decomposition 1b (multiple components). The forward FX swap trade, TR002 in Portfolio 2, uses the Standardized Approach for Counterparty Credit Risk (SA-CCR) framework and has no netting sets, no collateral sets, or no collateral positions.

Define Data

Define the foreign exchange (FX) spot currency exchange rate table.

format("default");
Base = ["EUR";"GBP";"GBP"];
Quote = ["USD";"USD";"EUR"];
SpotRate = [1.0543;1.2195;1.1567];
FXSpotTable = table(Base,Quote,SpotRate)
FXSpotTable=3×3 table
    Base     Quote    SpotRate
    _____    _____    ________

    "EUR"    "USD"     1.0543 
    "GBP"    "USD"     1.2195 
    "GBP"    "EUR"     1.1567

Define the SA-CCR CRIF file name.

SACCRCRIF = "SACCR_CRIF_FX.csv";

Create saccr Object

Construct the saccr object from SACCRCRIF.

mySACCR = saccr(SACCRCRIF, DomesticCurrency="USD", FXSpot=FXSpotTable)
