"Under SIPA, cash specifically refers to cash in a securities brokerage firm account from the sale of or for the purchase of securities. Cash from the sale of or for the purchase of investments that are not "securities" is not protected. Based on the information you have provided, it appears that you are not entitled to SIPC protection.
However, once claim forms are available, you should file a claim with the Trustee. The Trustee will evaluate your claim and will notify you whether or not your claim is allowed and in what amount, if any. "

I will not be able to paste here the chain of email correspondence I had with SIPC due to privacy reasons but I did told them specifically that my account had "Cash only, no positions, and all I did in my account was trading crude oil futures". Their reply included that cash and cash generated by trading "non-securities" is not covered.

Cash in a futures account is for the purchase of a non-security, and as such clearly not covered by SIPC. That's a no-brainer.
I read today frozen accounts will, hopefully, be transferred to some other random FCM within the next 48 hrs. Only 60% of account net liq value will be transferred, remaining 40% stays behind to cover potential loses at MF. This is all pending trustee approval of course, but that's the CME proposal.
