I can see where you're coming from and I might be inclined to give them the benefit of the doubt except:
-We had this exact same discussion here on ET where they engaged in the exact same obfuscation strategy (
https://www.elitetrader.com/et/threads/ib-yield-enhancement-program-question.301819/) so they clearly know what the issue is and this is their regular response to those types of questions.
-@ET180 and I had multiple posts that were specifically about the difference between FDIC and SIPC protection and which applied, in fact the vast majority of the posts on the thread and
the posts @def was replying to! were discussing this. And yet he "conveniently" decided that
I had made a mistake and swapped FDIC for SIPC. Seriously? And then comes back with "yep silly me for not spending great amount of detail and time in each of my responses." as if it was some minor matter and not the entire point of the entire conversation they jumped in on and I was somehow being unreasonable? Again, seriously? The first principle to assume the customer is an idiot is common to every IB rep I've spoken to, so I guess maybe they train them that way?
-After all that and multiple requests for a yes or no answer, they actually have yet to answer the freaking question on if the cash collateral is FDIC covered! Clearly it isn't, why are they doing the flim flam artist thing to avoid answering such a simple question?
-Then there's the twisting of my detailed explanation of the fact of every corporation's "small but non-zero chance that they'll default." into "I get it for you, you may not think IB is safe". Again purposely attempting to ignore the point that customers should expect compensation for losing SIPC and FDIC protection and instead twisting it into some kind of "IB is so safe why do you dare doubt us" bullshit.
-And then there's the self-righteous huff he worked himself into with his pedantic literalist interpretation of my use of the world "steal" as if I was accusing IB of an actual criminal act when I pointed out anyone can avoid giving half the borrow rate to IB (which is risk free money to them) and losing insurance protection by simply setting up a synthetic long. Are you freaking kidding me? If you told the guy "The price on this car is a steal" would he think you're literally going to go hotwire the car? Give me a break!
A straightforward read of this exchange is that both IB and this rep or at least the rep are being as evasive as possible on this particular subject, in which case snowball's chance in hell they'll take your advice. In fact if you read their posts you'll see that any time anyone questions their insurance coverage or SIPC/FDIC coverage they always default to the "its inconceivable such a well capitalized company as ours would ever default" answer rather than actually answering the question. You'll find that probably a dozen times here. Which begs the question as to why they have the Lloyds insurance or the FDIC splitting into bank accounts thing in the first place. So bottom line, guarantee they'll even entertain discussing that there's ever any chance at all of them defaulting, let alone what would happen to your stock/futures/cash if they did.
It's actually a far more charitable read that the rep is simply too lazy to read the questions they're answering and like some great electrical engineers I know take everything they hear absolutely literally and answer very abruptly. In that case at least IB isn't being dishonest and evasive as a matter of policy. But like I said, that kind of thing might make for a great engineer but it's the worst possible combination for someone ostensibly providing "customer service", of which this is one of the worst possible examples. Warning to everyone, this rep and this runaround is exactly representative of what you'll get any time you contact what they call "customer service" at IB.
BTW, being civil is answering folks questions in a straightforward manner, not assuming they're stupid and don't know the difference between something like FDIC and SIPC in a conversation that's specifically about the difference between FDIC and SIPC, and not purposely twisting their words to say something nearly opposite what they actually said. Calling out an uncivil behavior in that regard is not in any way uncivil, if you don't call people and especially companies on bullshit they'll just keep feeding it to you.
