If you're "confused" about my being a former NASD Principal, PM me and I'll give you the info so you can look it up. It's a matter of public record.
1. Where did you get the notion that SIPC does not cover theft and fraud from customers? What do you think it covers?
Let me first thank you for not turning this into a pissing match. I appreciate the respect, and I hope you feel the same. Try this link:

Click on the flash banner and that is a very nice overview of SIPC; I hope you will agree that my take on it is correct, and yours is incorrect.
2. If customer assets are segrated from Broker assets, as they are required to be... and the broker goes out of business, customers SHOULD get 100% of their money and securities back. If they don't, then there had to be some form of criminal act... and SIPC insures customers against such things up to the limit of SIPC coverage.
Well, we still disagree about there having to be fraud; otherwise, yes, and herein lies the interesting part wrt IB. IB sweeps your excess funds into a SIPC insured account for the night. So, if you are flat, all your money heads for safekeeping. This is not possible in a regular FCM, but as you mentioned, IB has a "dual role" if you will. This has the effect of insulating a futures customer funds from any onslaught of insolvency driven by other futures losses at the firm, since the funds swept are on the "stock" side, not the futures side, and hence are able to be SIPC insured.
3. What has margin got to do with any of this? What question are you asking that I haven't answered? Please organize your question and ask it again.
