the OCC Fund has only paid out once and it was only 8mm.
Enron only went bankrupt once.
Whether or not some very specific things have already happened before is not the best way to look at risk.
From what I could find OCC has $232 billion in "margin held" at the end of 2023 and the backstop of a $16.9 billion clearing fund. I could not easily find either a net or a gross exposure. Only a number of contracts which you can't easily put a value to. Without telling us how many chips are out on the casino floor we can't tell if that's a decent amount.
Imagine if Deutsch bank or similar ceased operations tomorrow and all the options contracts they sold had to go on OCCs books.
OCC requires margin deposits, but the vast majority of funds in deposit are securities which can obviously fluctuate in value.
I can imagine a feedback scenario where a drop in stock prices cause a margin call to the member firms. Those firms then have to cut margin lending, this causes margin call to individual customers who sell.
Look at my math. If the tax arb doesn’t compensate you for this risk, then this product isn’t for you.
Agreed. I sometimes enjoy going through the details of "who guarantees x" and "how does y actually clear".
I certainly don't think they're likely to fail, but it is interesting to ask "what would it take?"
