I'd appreciate IB's clarification on the following detail concerning customer account protection. Since SIPC's protection is limited to up to $100,000 in cash (out of a $500,000 total), would any cash in an IB Securities Account in excess of this amount be covered by IB's additional insurance policy from Lloyd's of London? For example, an investor thinks a major correction is imminent and liquidates his entire stock portfolio, taking his cash holding to over $100,000, say, $750,000. Would the additional $650,000 cash be covered by the Lloyd's policy? Thanks.
