#黑色星期一三十九周年
👉 黑色星期一，杠杆先跑一遍
October 19 marks the 39th anniversary of Black Monday in 1987.
The Dow plunged 22.6% in a single day, still the largest one-day drop on record.
The S&P 500 fell 20.5%, and the Nasdaq dropped 11.4%.
Around $500 billion in market value vanished in a day.
Hong Kong stocks were closed for four days that week.
When trading resumed, the Hang Seng Index fell 33% that day.
The Federal Reserve pledged to provide liquidity.
In 1988, U.S. markets introduced circuit breakers.
A 7% S&P 500 drop halts trading for 15 minutes; a 13% drop triggers another 15-minute halt.
A 20% drop closes the market for the day, while futures are capped at 7% overnight.
This year, the reasons for concern have changed.
Brent crude closed at $110 on Friday.
The VIX is at a four-month high, and Treasury yields are rising.
Some industry insiders say U.S. tech stocks have lost $1.9 trillion in value.
Over the weekend, tokenized contracts were the first to fall.
Within seconds, losses reached 5%.
CoinGlass says $51.6 million in positions were liquidated.
Crypto markets have no circuit breakers and trade around the clock.
Before U.S. markets even opened, leverage had already taken a first hit.
In crypto, selling pressure first lands on perpetual futures.
Do you think circuit breakers could stop a drop like the one in 1987? Share your thoughts in the comments.
