"Jiao Chao" in the Financial History of the Jin Dynasty: From Institutional Innovation to Monetary Evolution

Brief Introduction

"Jiao Chao" (交钞) was an early form of paper currency issued by the Jin Dynasty. As commercial activities in the north flourished, the issues of copper coin scarcity and circulation inconvenience became increasingly prominent. Building upon the monetary policies of the Liao and Song dynasties, the Jin Dynasty formally implemented the Jiao Chao. It was not only a key instrument for the Jin Dynasty to handle fiscal pressure and promote trade circulation but also a pivotal link in the history of Chinese currency, bridging previous and subsequent developments.

Core Knowledge Points

1. Issuance Background and Evolution
In the early Jin period, paper currency was not issued immediately; instead, the dynasty continued to use old coins from the Song and Liao dynasies along with copper coins. As the wars against the Song and Liao advanced and the occupied territories expanded, copper sources dried up. Combined with the demand for large-scale transactions, the Jin Shizong Emperor formally issued the "Jiao Chao" during the Dadning era (mid-12th century). Initially, the Jiao Chao circulated in parallel with copper coins, with a specified exchange rate, exhibiting characteristics of a certain standard system.

2. Status in the Monetary System
The Jiao Chao held a core position in the Jin Dynasty's monetary system. It was used not only for transactions in the civilian market but also became the primary payment method for the government to issue official salaries and collect taxes. The Jin Dynasty established "Bao Chao Kusu" (Treasuries of Paper Currency) to manage the printing, issuance, and redemption of the Jiao Chao. They attempted to maintain currency stability through a periodic "exchange" system, which involved regularly recalling old notes and issuing new ones to combat inflation.

3. Economic Impact
The promotion of the Jiao Chao greatly facilitated regional cross-border trade within the Jin Dynasty and with the Song and Mongol entities. However, as war expenditures increased, the late Jin Dynasty over-issued Jiao Chao, leading to hyperinflation and a decline in public confidence. Ultimately, after the establishment of the Yuan Dynasty, it was replaced by new systems such as the "Zhongtong Chao" and "Zhiyuan Chao."

Connection to the Context of Xuzi Zhi Tongjian

It is worth noting that Xuzi Zhi Tongjian (Continued Comprehensive Mirror for Aid in Governance) primarily records historical events from the Later Zhou and Northern Song dynasties to the Yuan Dynasty, compiled by Gu Yingtai in the early Qing Dynasty. In relevant volumes (those involving the Jin Shizong or Jin Zhangzong periods, or chapters on Song-Jin interactions), although the "Jiao Chao" is not listed as an independent entry, it is often indirectly reflected through records of Jin dynasty policy relaxations, market reforms, or fiscal income and expenditure conditions, illustrating the actual circulation of paper currency in cross-border trade between the two states.

The book's description of economic interactions during the standoff between the Song and Jin dynasties provides a historical context for understanding the cross-border function of the Jiao Chao. For example, documents mention phenomena where currencies of both sides were mixed and used in border markets, highlighting the importance of the Jiao Chao in breaking the geographical restrictions of copper coins and realizing functions of value storage and payment. By combining these historical materials, we can gain a more multidimensional understanding that the Jiao Chao was not merely a financial tool but also a micro-reflection of geopolitical and economic integration during the Song-Jin era, reflecting the maturation and complex evolution of China's early credit currency system.
