This time period was also known as the “Southeast Asian Financial Crisis”. To this day there are still empty 60 story skyscrapers in Bangkok because of how bad it was.
A big lesson from that event are that foreign currency reserves are never enough.
Korea had something like $300 billion in foreign currency reserves and was wiped out in days. $3 trillion is a lot, but adjusted for China’s population, and the fact that they will need to use those reserves to last 1 year maybe 2, and they start to look much smaller.
Also this kind of a crisis would not be like a tech bubble. Tech Bubbles are bad, but they do not invoke the banking system. If the banking system falls, the general rule of thumb is a minimum 10 year recovery.
It’s worth noting that this is the position adopted by George Friedman in his book “The Next 100 Years” where he predicts the fall of China and also North Korea by 2030 at the very latest.
