"In a strict sense, there wasn't any risk - if the world had behaved as it did in the past."
- Merton Miller, Economist & Nobel Laureate
PS above quote is from "When Genius Failed" by Roger Lowenstein
In common parlance, it's called an oxymoron.
In scientific academia, it's called a disproof.
In economics, it's called an undisputed fact.
To those whose trade is risk, it's called an opportunity.
Will interactive brokers be affected? This bail-in thing is a risk to all customers. If our broker default because of the cost of bail-in, wouldn't all of us be affected? I am a customer of IBKR.
Well, the problem is this was (as described by experts on this)
one isolated incident. But, keep in mind that "one isolated incident" is an entirely accurate description of the "first occurrence of a systemic failure".
The problem as I see it is that a single trader was able to hang liabilities on clearing members to the tune of about 40% of his assets prior to the trade. Imagine if this had been a big trading desk, not a personal account.
It's possible to see how a clearing member or two going down on defaults could take down even very stable brokers. This is a pretty scary situation because the panic that would ensue on a large-scale default like that would be accompanied by a crippling blow to liquidity as confidence in the backstop to the counter party is undermined. So, as a trader, you know SIPC likely is going to be paying pennies on the dollar if this unravels, but you don't know if your counter party (and all layers between) will make good on their side of the trade.
To an extent, the American market (and western markets generally) works on the idea that moving parts can be kept moving by adding more moving parts. And because the new moving parts added have not failed yet (in their short 10-ish year history), they are presumed to be working well. But as anyone who's ever looked at a system can tell you, more moving parts is more parts to fail, in more ways.
Which circles me back to a point I made on another thread about this. Unprecedented is not the same as impossible. Though economic theory treats it that way.
