Song Dynasty Paper Money Jiaozi
🏮 The Birth of Paper Money: A Story of Innovation and Collapse
Hello, this is Kori.
Let me take you somewhere unexpected.
Imagine you’re a silk merchant in 11th-century Sichuan, China.
You’ve just found a great deal—fine silk at a low price—but there’s one problem.
You can’t pay for it easily.
At the time, copper was scarce in the region, so people used iron coins.
And not just a few—hundreds of kilograms of them.
To buy silk, you’d need carts. Animals. Days of travel.
And if bandits showed up? There was no running away with that weight.
So people came up with a simple, brilliant idea.
Instead of carrying metal, why not carry trust?
A piece of paper representing value.
That small idea would become one of humanity’s greatest financial innovations—
and eventually, one of its most painful economic disasters.
This is the story of Jiaozi, the world’s first paper money.
💡 Innovation Begins: Escaping the Weight of Iron Coins
During the Northern Song Dynasty, Sichuan was a thriving commercial hub.
But trade had a serious problem: money was too heavy.
One unit of iron coins could weigh up to 40 kilograms.
Large transactions required entire transport teams.
So sixteen wealthy merchant families formed a kind of early banking alliance.
Here’s what they did:
- Merchants deposited iron coins
- The alliance issued paper certificates
- Those certificates promised redemption in metal coins
At first, it was just a receipt.
But people quickly realized something important:
Why redeem it at all?
Why not just trade the paper itself?
That’s when Jiaozi transformed from a receipt into money.
A natural, market-driven birth of paper currency.
🏛️ Government Intervention: The First Official Paper Money
As Jiaozi became widely used, problems began.
Some merchants issued more paper than they had coins.
That’s when the government stepped in.
In 1023, the Song Dynasty:
- Banned private issuance
- Established a government office
- Began issuing official Jiaozi
This was the world’s first state-backed paper money.
At first, it worked beautifully.
- Strict issuance limits
- Full backing with metal reserves
- Strong public trust
But history rarely lets success stay simple.
⚔️ A Nation Under Pressure: War and Tribute
The Song Dynasty was rich—but militarily weak.
It faced constant threats from northern states like:
- Liao (Khitan Empire)
- Western Xia
After years of war, the Song signed a peace treaty in 1004.
Known as the Treaty of Chanyuan, it came at a cost:
- 100,000 taels of silver per year
- 200,000 bolts of silk
And later, even more payments to Western Xia.
Peace wasn’t free.
It was extremely expensive.
💸 The Breaking Point: Printing Without Limits
As military costs exploded, the government ran out of money.
And then came the temptation.
Printing more.
At first, Jiaozi issuance was tightly controlled—about 1.25 million units.
But as war expenses grew, that number skyrocketed into the tens of millions.
Without enough metal backing.
Without control.
Just paper.
And once that line is crossed, the consequences are almost always the same.
📉 Inflation Begins: When Trust Collapses
Money is not just paper.
It’s trust.
And when too much money enters the system, that trust breaks.
Here’s what happened:
- Jiaozi flooded the market
- Prices began rising rapidly
- Confidence collapsed
Eventually:
- Paper money lost most of its value
- It traded at 1/10, even 1/100 of face value
- People stopped accepting it altogether
What started as innovation became economic chaos.
🔄 A Failed Reset: Renaming the Currency
In 1107, the government tried to fix things.
They introduced a new currency called “Qianyin” (Qianyin).
But it was just a rebranding.
No real reform.
No restored trust.
And so, it failed just like Jiaozi.
🏁 The Pattern Repeats: Southern Song Collapse
After the Northern Song fell to the Jin Dynasty, the Southern Song continued the pattern.
Facing:
- Jin invasions
- Mongol expansion
They issued another currency: Huizi.
And once again:
- Excess printing
- Weak backing
- Inflation
The cycle repeated.
Until the dynasty itself collapsed.
📊 Evolution of Song Dynasty Paper Money
| Currency | Period | Key Feature | Cause of Inflation |
|---|---|---|---|
| Jiaozi | Northern Song | First paper money, born from trade | War expenses, tribute payments |
| Qianyin | Late Northern Song | Replacement currency | Lack of backing, overprinting |
| Huizi | Southern Song | War-financing currency | Military pressure, declining revenue |
🧠 Kori’s Take
This story always makes me pause a bit.
Because in the end, money isn’t just about numbers.
It’s about belief.
The Song Dynasty didn’t collapse because paper money was a bad idea.
It collapsed because it broke trust.
War made leaders choose the easiest solution—printing more.
But the real cost?
Was paid by ordinary people.
Rising prices.
Lost savings.
Economic instability.
And that’s the part that always hits hardest.
Even today, the lesson still stands:
When money loses its connection to reality,
it doesn’t just lose value—it takes the economy with it.

At some point, a thought naturally comes to mind.
War is not only fought with weapons—it is, in many ways, fought with money.
If we zoom out and look at history more broadly, nations have always developed new ways to finance war.
In ancient Rome, soldiers were paid with salt—known as “salarium,” the origin of the word “salary.”
By the modern era, governments began issuing bonds to their citizens. The United States, for example, has long relied on Treasury bonds to fund large-scale wars.

Seen through this lens, the Song Dynasty’s use of Jiaozi was not an isolated case.
Under the immense pressure of military spending, the state chose the most accessible solution—issuing more currency.
And as we’ve seen, that decision ultimately led to inflation and the erosion of trust.
❓ Song Dynasty Paper Money Jiaozi Q&A
Q1. Was Jiaozi originally issued by the government?
No. It started as private merchant-issued certificates in Sichuan. The government later took control in 1023.
Q2. Why did the Song Dynasty print so much money?
Mainly due to massive military costs and tribute payments to neighboring states like Liao and Western Xia.
Q3. How bad was the inflation?
Severe. The value of Jiaozi fell to as low as 1/100 of its face value, effectively becoming worthless.
