AI Summary
Summary
The thread discusses the safety of 401k accounts exceeding SIPC limits, clarifying that 401ks are governed by ERISA (not SIPC) and held in trust, making them very safe from employer or recordkeeper bankruptcy.
Dominant sentiment is reassuring: users believe large-scale fraud is nearly impossible due to strict regulation, and funds are protected even if the institution fails.
No specific earnings or market-moving events are discussed; the focus is purely on structural protections for retirement accounts.

[+6] u/DaemonTargaryen2024: >What happens to a 401k over the SIPC limit
401ks aren't covered by SIPC (unless it's in a [brokerage-link](https://www.investopedia.com/articles/personal-finance/061314/rise-401k-brokerage-accounts.asp)). 401ks are covered by [ERISA](https://www.dol.gov/general/topic/retirement/erisa).
>and your institution holding your 401k became insolvent (or fraud occurred), do all 401k accounts remain whole?
Yes. 401ks are held [in trust](https://www.irs.gov/retirement-plans/irc-401k-plans-establishing-a-401k-plan#:~:text=plan.-,Arrange%20a%20trust%20fund%20for%20the%20plan’s%20assets,-A). If the employer or 401k recordkeeper goes bankrupt, the 401k itself is unaffected, as it's housed separately.
401ks are so ridiculously [regulated](https://www.irs.gov/retirement-plans/401k-plans) that large scale institutional fraud is impossible.
>Generally, how safe is a person’s money if their 401k is over $500k and the brokerage goes under or if fraud occurs?
Very safe, and again there's no $500k SIPC threshold for 401ks.
Your 401k is not safe from *market* losses, of course. [SIPC does not protect](https://www.sipc.org/for-investors/what-sipc-protects#:~:text=SIPC%20does%20not%20protect%20against%20the%20decline%20in%20value%20of%20your%20securities) brokerage accounts against losses either, to be clear.
>Would they be screwed if a major firm fails/fraud occurs?
Not at all
