This is a long series of citations that seems on its face to confirm that broker-dealers can't use customer funds to post DTCC collateral.


Where do you get that from?

Everything in the rule is about not using customer funds for proprietary purposes. Not co-mingling customer and brokerage funds. Meaning the brokerage can’t make their own trades with customer money.

There isn’t a single word against using customer funds to purchase customer shares.

It’s a rule against using customer funds for non-customer activities.

If anything the problem that Robinhood ran up against was net capital requirements under 15c3-1.


It seems that clearinghouse collateral is considered "firm overhead"?


Yes. I don't really understand what is being argued here.

There are three stages; execution, clearing and settlement.

Execution is the formation of the legal-binding agreement, e.g. a contract to exchange money for stock. For these cases, this is happening via matching on an exchange between a buyer and a seller. If the time of the trade is T, then happens at T+0.

Clearing is the paperwork activity that takes place after execution that include the due diligence steps of making sure that trades match, as well as other stuff that can reduce the amount of settlement activity. This happens in the period from T+delta through T+2-delta.

Settlement is the actual exchange, and is the point at which legal ownership of the stock changes. This happens at T+2.

It is obviously true that the brokerage uses client money for settlement; otherwise how would the broker ever fund any trades by its clients?

Is also obviously true that prior to the moment of settlement the client money is ... the client money, and subject to segregation. In other words, from the broker perspective, it's always client money until it's off their books.

The time when the NSCC wants to see adequate collateral is exactly during the clearing period, when the actual counterparty risk exists. That collateral absolutely cannot be from client money due to the segregation rules because the whole purpose of the collateral is to reduce the risk of a broker failure causing clients to lose money.

RH's collateral requirements blew up because some substantial proportion of their clientele was attempting to go long GME during a period of vast price volatility, and the NSCC's procedure for determining those requirements takes into account primarily the size of the net long position and the volatility for each member.

Net result: RH has to go raise capital in a hurry; RH stops its clients from going any further long GME.


So I'd say the truth came out in an interview late Sunday evening between Elon Musk and Robinhood CEO Vlad Tenev. [1]

> Tenev explained that while he was sleeping, at 3:30 a.m. PT on Thursday, Robinhood's operations team received a file from the National Securities Clearing Corporation (NSCC) that as a clearing broker, Robinhood Securities needed to put up around $3 billion "an order of magnitude more than what it typically is."

> So, it was unprecedented activity. I don't have the full context about what was going on, what's going on in the NSCC to make these calculations," Tenev added — prompting Musk to joke if someone was “holding you hostage right now.”

> Tenev said that after putting their heads together and calling the higher-ups at the NSCC, they got that figure down to $1.4 billion, from the initial $3 billion. "We were making some progress, right, but still a higher number," he added.

> Next, Tenev said they had to explain how to "manage risk in these symbols" by restricting activity in the volatile stocks. After that, the NSCC said the charges on the deposit were $700 million, which Robinhood "paid promptly."

You don't even have to read between the lines here. Robinhood isn't the problem here. Massive long retail demand is crushing shorts, which is potentially opening the clearing houses to multi-billion dollar losses. The way to stem the losses is to stem buying pressure and get the stock to come down.

So call up Robinhood and demand $3 billion in collateral (an order of magnitude higher than the day before) unless they stop the buying pressure on the shares. When Robinhood agreed to limit buying, the NSCC was willing to drop the collateral requirement to $700 million.

This isn't about a share-for-share clearing / transaction cost for each buy order entered. Those buy orders are cash funded and zero risk for Robinhood and zero risk to NSCC / DTCC. This is about extorting Robinhood to stave off the bankruptcy and subsequent contagion of a 140% short interest on a stock that's gone up 70x in just a few months.

Look, I agree that Robinhood can't use customer funds to pay extortion demands from the clearing houses. My point is that Robinhood clearing fully cash-paid buy orders does not incur additional clearing costs to Robinhood. It's not a per-order transaction fee. It's a slush fund which is used to pad against defaults.

> "Now, why is that so high? Like this seems like, it sounds like an unprecedented increase in demand for capital. What formula did they use to calculate that?" Musk asked.

> To contextualize the number, the app's CEO noted that RobinHood had raised about $2 billion in total venture funding. He added that the formula was “not fully transparent” and “not publicly shared.”

I'm sorry, but you just conceded the whole discussion (turns out: it was definitely clearing collateral calls!) but then moved the goalposts to a conspiracy in which the clearinghouses were protecting the shorts.
