Personal Guaranty Creates Prohibited Transaction?

[Guest tschotland]

Hello,

I am trying to open futures trading accounts for my IRA and profit sharing plan (single participant plan) so that they may be traded by CTAs. The brokerage says I must sign a personal guaranty on the accounts. I am concerned that this may create a prohibited transaction. The brokerage claims thousands of people have signed them. Is there an issue here? I'd appreciate any insight.

I am cross-posting this to the IRA board. I don't find a board on defined contribution plans.

Thanks,

Tom
