Stable Value Fund or Money Market Account

Hello I just had a quick question in reference to 457 Plans or 401(a) plans. Is the plan's fund lineup required to provide a Stable Value Fund or Money Market Account as one of the options?

This is an investment question and most of us on here are ERISA people, not Registered Rep's.   In my career, I have sold investment portfolios for retirement plans, however, and do not know of any plan which would be "required" to provide a Stable Value or Money Market fund."  Do you have a DOL or IRS cite which would support this idea?

I think the "requirement" OP is referencing is how many investment folks explain 404c diversification requirement.  That one alternative should be for capital preservation, like a MM or SVF.

The plan may, in various instances (terminating participant, participant undergoing divorce or other personal change, plan termination, global pandemic that gets even worse) need a short-term, highly liquid investment, so probably imprudent not to include as an option, but prudence is based on facts and circumstances.
