A short squeeze is a funding problem before it is a price problem
Eat the Rich: The GameStop Saga · 2022
The idea
The GameStop episode is usually told as a price story. The series on it is more useful on the plumbing. When the price spiked, the clearing house demanded collateral from brokers for trades that would not settle for two days, and the broker that could not raise it stopped its customers buying. The squeeze hurt the shorts through margin, but it nearly broke a broker through settlement. The question most candidates cannot answer, why a broker would halt buying, has a mechanical answer: the collateral call lands before the trade clears.
Settlement takes days, and the collateral call arrives before the trade clears. That gap is where a squeeze does its damage.
When it works
Any long/short, prime brokerage or market structure conversation that touches GameStop.
When it may fail
The series takes a side on whether the halt was fair. The mechanism is not in dispute; the motives are, and an interviewer will notice if you borrow the series' certainty.
How to use it
Describe the chain in order: buyer, broker, clearing house, collateral, settlement. Place the margin call at the clearing house and the halt at the broker, and you have answered the question that trips up most people.
Where it came from

What the source says. Three episodes on the squeeze, the broker that halted buying and the reason it did, raising the clearing and settlement question most candidates cannot answer.

A risk limit is a decision about who has to be woken up
A limit is an escalation rule: it decides when a problem must move up the firm, not just how big it may be.

One person holding both the trade and its settlement is the whole failure
Whoever can take a position must not be the person who confirms it. Separate the hands, and the rest of the controls become possible.

Traders who agree on nothing else all agree about risk control
The common factor among people who last is not how they pick trades but how they limit what a wrong one costs.

A bubble needs marketability, money and credit, and speculation together
Check all three legs, marketability, cheap money and a population buying for resale, before calling something a bubble.
