Create saccr Object and Compute Regulatory Values for Multiple Asset Classes
This example shows how to create a saccr object for trades representing multiple asset classes. The trades are:
Tr001— Asset class (IR), 10 Year Interest Rate Swap in EURTr002— Asset class (FX), EUR/GBP Forward FX Swap (Trade Decomposition "1b")Tr003— Asset class (CR_SN), Single name CDS on Spain (Short Protection)Tr004— Asset class (CR_IX), CDS iTraxx Europe Crossover Index Receiver OptionTr005— Asset class (EQ_SN), Long Call Option on AAPLTr006— Asset class (EQ_IX), Long Put Option on S&P500 IndexTr007_SOpt— Asset class (CO), Long Put Option on CORN (sold option with premium paid)
These trades are in Portfolio 4. They use the Standardized Approach for Counterparty Credit Risk (SA-CCR) framework and have 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)
