The Scenario Up/Down PV.CCY
measures are vectors of shocked prices indexed by risk weight.
For each Sensitivity Currency, the Shock Up/Down prices are
converted to the reference currency using the IFxRates API. After this
currency conversion, the values are aggregated for each Bucket.
If the Counter Currency for a Risk Factor does not equal the
reporting currency, then filtering may be used. See Base Currency and Jurisdiction.
