The extent of decline that will be remembered in history.

Experiencing the actual decline that is likely to be remembered in current history will become a significant asset in the future.

It is not an experience that can easily happen to see one's own assets decreasing on a daily basis.

I wonder what it will be called later.

Japan will undoubtedly be referred to as the 'Ueda Shock', but globally it might be called the '24 Global Stock Market Crash', or something similar.
