Sure, someone could use @Risk to create a small model with a few attritional and large loss sources of risk, attach a quota share or simple XoL and produce some output, but they would be a decade behind other technologies. I've seen plenty of Excel-type capital models and they are not adequate.
how about the copula structure and parameters for reserve risk, current year pricing risk? From my experience the most complicated was the ESG and valuing the assets mostly bonds as noted above.

Its a cost center as you noted, not adequate, too simple, yet, if it got more complicated, no one would use it since that would devolve into everyone trying to determine the "drivers" of results on one really understanding it. JMO

From my experience, excel was useful for separately modelling (simple one) the parameters used in the ECM, but that's pretty much it.

Excel is great for being a supplemental tool for the big ECM software. Ofc, there are better alternatives.

Excel was only ever meant for mild-moderate financial modelling.

Please stop abusing it.


I can see doing a basic trace of how the model works for testing purposes but anything beyond that is too much.
