$PI Economists say:

"Once a war breaks out, bank deposits are probably gone. History shows that once a war happens, the financial system is the first to fail. Mobile payments are immediately brought to a standstill. Even if the digital money is still there, you may not be able to withdraw it. It could even lead to inflation, with money shrinking drastically. In history, even a sack of money couldn’t buy more than a few pounds of rice. So don’t pin all your “assets” on just one form. In a small crisis, cash is king. In a medium crisis, gold is king. In a major crisis, food is king."
​A person with a sound wealth-management mindset would not put all their eggs in one basket. In peacetime, banks are nothing more than the safest basket to store eggs. But if war breaks out, that basket may be the first to become unreliable and the least trustworthy. Whether a war will happen, and when it will happen, is often impossible to predict. Once a war breaks out, ordinary people’s wealth could vanish overnight. At that point, no amount of crying or regret would help.
​In every war or period of social turmoil in history, the first thing to collapse is usually the financial system. Wars or unrest often cause logistics bottlenecks and restrict production, which then drives prices soaring. Sometimes, all the money in a single sack may not even be enough to buy a few pounds of rice. So for a smart person, I would keep all my money in the bank, and in addition, I would allocate some assets other than cash—so that I can hedge risks to the maximum extent when the time comes.
​In a small crisis, cash is king. In a moderate crisis, gold is king. In a severe crisis, food is king. We need to have a large amount of cash on hand—this is the foundation for directly responding to a crisis. We should also buy a certain amount of gold, and allocate a certain proportion to stocks, funds, and real estate. As long as your wealth is diversified, you can best deal with all kinds of crises and inflation. We never know whether tomorrow or an unexpected event will come first. We must learn to prepare for the worst.
