Chapter 11 Bankruptcy Basics Chapter 11 Bankruptcy Basics Background Chapter 11 - Bankruptcy Basics https://www.uscourts.gov/services-forms/bankruptcy/bankruptcy-basics/chapter-11-bankruptcy-basics I searched about US Chapter 11. US Chapter 11’s good points There are some good points of US Chapter 11. (1)Speed up Reorganization If almost bankruptcy company provides essential things or services, the company will raise their prices. Because the company makes up for losses. It causes the social cost higher. (2)Prevent excessive repayments US Chapter 11 can prevent excessive repayments. In Japan, if someone borrow money from a bank, he/she will need a personal guarantee. It causes to discourage entrepreneurs. (3)Visible processes and goals I heard that 99% of new companies will bankrupt. We tend to focus on rest 1%, but 99% is bigger than 1%.

Simple calculation Simple calculation Background Bank Of Japan(BOJ) has 7% of Tokyo Prime stock market shares. The shares book value is 34 trillion yen. Tokyo stock market falls today Sum of Tokyo Prime stock was 962 trillion yen at July 31, 2024. Index of Tokyo Prime stock was between 1400-1450 at July 31, 2024. Today’s index was 1150. In fact, 962:1425=x:1150. X is 776. At Aug 5, 2024, sum of Tokyo Prime stock was 776 trillion yen. In fact, BOJ has 54 trillion yen of Tokyo Prime stock. What do I want to say? If index of Tokyo Prime stock falls down under 723, then BOJ bankrupts or becomes insolvent. 1150 * 54 / 34 = 723. If index of Tokyo Prime stock falls more 40% than today, Japan economy ends. Caution This simple calculation may include mistakes which I don’t know.
