Disintermediation

Disintermediation occurs in high or low interest rate environments? Can someone please explain the concept in plain words?

High interest rate. Policyholder surrender their policy for cash to reinvest in a higher rate => Shorten the liab DUR => Increase the sponsor liquidity need

It’s withdrawal of funds from (L.I.) policy actually, so includes full surrender and policy loans. Motivation for investor: - IR arbitrage. Re-investment for a higher rate elsewhere. Implication for institution: - Shotened Liability duration means instant liquidity requirement, which could mean sales of bonds at a realised loss to cover the withdrawal. - An asset/liability duration mismatch would exaccerbate the above.
