1. Historical Context
During the Song Dynasty of China (960-1279 AD), trade flourished exponentially, demanding a gigantic amount of iron and copper coins to carry out everyday commercial transactions.
2. The Breakdown Event
Iron coins were extremely heavy and of little individual value, forcing merchants to transport cartloads of metal to carry out high-volume transactions. In Sichuan province, merchants began depositing their heavy coins in trusted depository houses in exchange for signed paper receipts. These receipts, known as 'Jiaozi', began to circulate from hand to hand as an alternative means of payment. Seeing the convenience of the system, the government of the Song dynasty assumed the monopoly of issuance in the year 1024, issuing the first official forced tender paper money with limited metallic backing.
3. Global Economic Impact
The Jiaozi facilitated internal trade in China on a large scale, but the government's temptation to print excess paper money to finance wars against neighboring kingdoms caused severe episodes of inflation that forced the temporary abandonment of the system in later dynasties.
Key Financial Lesson (Psychology of Money)
The transactional convenience of paper money always trumps the physical discomfort of metals. However, money backed solely by the trust of the issuer requires strict government fiscal discipline to avoid chronic devaluation.
4. Practical Case or Real Life Example
The Venetian traveler Marco Polo was amazed by the use of paper money in China in the 13th century, describing in his diaries with amazement how the Emperor created wealth from nothing from the bark of mulberry trees.
