How severe can a country's currency crisis be? Just look at Iran.

The rial to USD exchange rate has fallen to 1,470,000:1 — in other words, $879 can buy a "luxurious" life in Iran. It sounds like a joke, but behind it is the collapse of the entire economic system.

Where is the problem? Limited oil dollar revenue, foreign exchange reserves being diverted and consumed by various parties, and ultimately ordinary people are left to clean up the mess — the fiat currency in their hands keeps depreciating, and purchasing power plummets. In just 15 years, Iranians' wealth has shrunk by 99%.

This case is worth pondering: when government credit and fiat currency systems fail, how quickly does wealth evaporate? Rising prices, savings turning into bubbles, and asset allocation ability determine who can preserve their wealth. From Iran to Zimbabwe to Venezuela, history repeatedly reenacts the same script — this is also why more and more people are paying attention to asset diversification and seeking stable value storage.
