I want to perform stress test / var calculation for portfolio of FX derivatives (one currency pair). How do I come up with reasonably meaningful scenario for spot rate / vol surface structure trajectories?Should I also simulate rates and take into account carry trade? What about interventions? Correlation with stock markets?Obvious way would be to run somerthing like Heston to come up with vol / spot interdependency, but Hestons calibration is not very stable and I am curious if any more direct usage of historical data is possible.Will be very grateful for any hints / references.
