Have there been financial crises in Chinese history? If so, what were their characteristics?

Yes, there were, and quite a few. However, ancient financial crises differed from what we refer to as "financial crises" today (like the one in 2008). Ancient times lacked complex financial derivatives like stocks and futures, so crises were typically more direct, primarily revolving around money (currency), grain (goods), and government credit.

Imagine it as an ancient "economic earthquake" – though no skyscrapers collapsed, it was enough to bankrupt ordinary people and even lead to the downfall of a dynasty.

Below, I'll give you a few typical examples to illustrate:

1. Emperor Wu of Han's "White Deer Skin Currency": A Financial Scam Orchestrated by the Emperor

Emperor Wu of Han was a man of great vision and strategy, but he spent money like water, especially on campaigns against the Xiongnu, almost emptying the imperial treasury. What to do? He came up with a "brilliant" idea.

The Audacious Scheme: He had a white deer from the imperial gardens killed, took its hide, and made it into square "skin currency" pieces, each one foot square. He then decreed that when princes and nobles had an audience with the emperor, they had to present their jade bi (a ceremonial disc) on top of this skin currency. The price of one piece of skin currency was set at 400,000 coins!
What Was Its True Nature: Was this piece of hide valuable in itself? No. It was merely a token. Emperor Wu used his imperial power to forcibly assign an extremely high value to a piece of hide, which was essentially a form of targeted extortion, seizing wealth from princes and nobles.
Consequences: This "currency," completely devoid of any credit foundation, severely disrupted the economic order of the time. Everyone understood what was happening, leading to immense distrust in the government's monetary policy. Although it primarily victimized the aristocracy, this act undermined the entire nation's financial credit foundation, a classic example of a currency crisis caused by government abuse of power.

2. The Song Dynasty's "Jiaozi": From Great Innovation to the First Inflation in History

The Song Dynasty was very prosperous with thriving commerce, but trading with piles of copper and iron coins was highly inconvenient. Thus, merchants in Chengdu, Sichuan, invented "Jiaozi" – the world's first paper currency.

Early Stage (Private Version): Initially, Jiaozi were deposit certificates issued by shops, enjoying excellent credit and redeemable at any time for actual silver and gold (the hard currencies of the time were copper and iron coins).
Middle Stage (Official Version): The government saw its potential and nationalized its issuance. Initially, they were relatively restrained, issuing paper money backed by a corresponding amount of reserves (copper coins).
Later Stage (Collapse Version): Later, the Song Dynasty also faced wars, leading to enormous military expenditures. The government began to frantically print Jiaozi, but the underlying reserves were far from sufficient. The result was an increasing amount of paper money in circulation, but less and less could be exchanged for goods.
Consequences: Severe inflation. Today, 100 guan of Jiaozi in your hand might buy a cow, but tomorrow it might not even buy a chicken. The common people's wealth was wiped out, and the economy plunged into chaos. This was the first clearly documented financial crisis in Chinese history, and indeed world history, caused by the over-issuance of paper currency.

3. The "Silver Crisis" of the Late Ming Dynasty: The Straw That Broke the Camel's Back

In the mid-to-late Ming Dynasty, silver became the primary circulating currency, used for both business transactions and tax payments. However, China had few silver mines of its own, relying heavily on imports from the Americas (via Spain and Portugal).

Economic Lifeline in Others' Hands: This laid a huge hidden danger. When international trade routes were disrupted (e.g., due to wars, maritime bans), or when overseas silver production declined, the inflow of silver into China would sharply decrease.
Domestic "Money Shortage": The scarcity of silver in the market led to what is known as deflation. Silver became increasingly valuable. While this might sound good, it was a disaster for ordinary people.
The Plight of Farmers: Farmers sold their grain for copper coins, but had to pay taxes in silver. Under deflation, where one tael of silver might have previously exchanged for 1,000 copper coins, it later required 2,000 or even more copper coins to obtain one tael of silver. This effectively more than doubled the farmers' tax burden!
Consequences: Consequently, large numbers of farmers went bankrupt and became displaced people. Social tensions escalated sharply, ultimately igniting the peasant uprisings of the late Ming Dynasty. It can be said that this financial crisis, triggered by the silver supply, was one of the significant factors accelerating the Ming Dynasty's demise.

Summary of Characteristics of Ancient Financial Crises:

Power-Driven: Often, they were caused by emperors or governments abusing their power to "create money out of thin air" or forcibly alter currency rules to solve financial difficulties.
Currency-Centric: The core of the crisis often revolved around currency itself, such as debased currency, over-issuance of paper money, or imbalances in exchange rates between different currencies (gold, silver, copper).
Closely Tied to the Real Economy (Especially Agriculture): Unlike modern finance, which can "idle," ancient financial crises quickly spread to agriculture and handicrafts. When compounded by natural disasters, they immediately escalated into social and political crises.

Therefore, although the forms differ, the underlying logic of "credit collapse, wealth evaporation, and social unrest" behind financial crises is consistent throughout history. History always repeats the same stories in different ways.
