I have a few questions I'm hoping to get some help on....
Longevity swaps:
How do longevity swaps impact the BEL and the SCR (e.g. for annuity business)? My thinking is that the BEL is still modelled using best estimate mortality assumptions (the cashflows from the longevity swap aren't modelled). On the asset side, assets are reduced by the PV of the fixed payment leg and increased by the PV of the floating leg (similarly to how reinsurance premiums and recoveries would be accounted for). Any collateral payments would also be modelled as part of the assets. The longevity SCR would be impacted as follows: the lighter mortality (claims for longer durations) resulting from the stress mean stressed assets would be higher (assuming the gap between the floating and fix payment legs widens at the tails). The counterparty default SCR would also increase. Is that right?
Would this differ if the longevity swap was structured as a derivative rather than a reinsurance arrangement?
Mortality vs longevity SCR:
How does the SCR for the mortality risk SCR differ to that of the longevity risk SCR? Is the latter only calculated for business with longevity risk (e.g. annuities)? The stresses would also be different right (e.g. x% reduction in mortality rates rather than an increase)?
Is it the interest rate sub-module that would be impacted by higher/lower cash holdings?

Yes: the market risk stresses for equities tend to be higher than for property (and will be lower still for bonds and cash).
