I was wondering the same. From what I understand the discount rate used for liabilities for pensions should already account for the inflation. The CFA 2015 paper Q1 B only included the discount rate as the minimum return, not adjusting for inflation. They didn’t explain why inflation was not included, but I assume it’s because the discount rate should already account for it. I believe insurers work in a similar way, as they also have defined liabilities and a discount rate for them.
For endownments or foundations, whenever it says “maintain real value of assets”, or something similar, we should add inflation as far as I know.
That’s my understanding.
