In the 1700s, Qing China relied on a bimetal money system: copper-alloy cash coins for everyday purchases and silver (measured in taels) for many taxes and large payments. This split worked when the exchange rate between copper cash and silver stayed relatively stable. It also meant that problems in either metal’s supply could quickly disrupt markets and state finance.
Soon after the Qianlong Emperor’s reign began, China faced a shortage of copper needed to mint cash coins. The shortage mattered because cash coins were the main small-change currency for wages and daily trade. The state’s ability to maintain regular mint output became a recurring issue in later monetary strains.
Copper from Yunnan’s mines helped relieve the shortage and allowed the Qing government to expand coin production. More reliable cash-coin supply supported market transactions and wage payments. This improvement, however, depended on continued access to copper sources and effective mint administration.
As the Qing state faced expensive military campaigns, the pressure on public finances increased. Over time, the quality and size of Qianlong-era cash coins deteriorated, reflecting efforts to stretch copper supplies and lower production costs. These changes signaled how fiscal stress could translate into monetary stress.
In 1794 the Qing government ordered provincial mints to close, an unusually strong intervention in the minting system. The closures reflected tightening copper supplies and administrative efforts to control coin output. Although mints later reopened, the episode highlighted the system’s vulnerability to metal supply problems.
During the Daoguang Emperor’s reign (1820–1850), parts of the economy experienced strong deflation when measured in silver, with falling prices and wages. Deflation made it harder for many people to earn enough to meet fixed obligations, including taxes commonly assessed in silver. This period set the stage for sharper currency tensions between copper cash and silver.
By the late 1820s and 1830s, silver began flowing out of China in large quantities, widely associated with the expanding opium trade and international trade dynamics. Silver scarcity pushed up silver’s value relative to copper cash, disrupting exchange rates. Because many taxes were demanded in silver while many wages were paid in copper, this shift increased burdens and instability.
The Qing crackdown on opium in 1839 helped trigger the First Opium War (1839–1842). War costs further strained state finances already stressed by silver shortages and a difficult copper–silver exchange environment. The conflict also opened the way to new treaty obligations that would require large silver payments.
The Treaty of Nanjing (1842) ended the First Opium War and required China to pay Britain an indemnity and accept major trade changes, including opening treaty ports. Indemnity payments mattered monetarily because they increased demand for silver at a time when silver was already under pressure. This reinforced the copper–silver imbalance that affected taxes, wages, and prices.
In 1853 the Qing government issued the Great Qing Treasure Note (Da-Qing Baochao), paper money denominated in copper-cash units (wén). Notes were commonly introduced through salary payments to soldiers and officials, pushing them into circulation. This marked a major shift toward state paper credit during wartime finance.
Alongside cash-denominated notes, the Qing state issued Hubu Guanpiao notes denominated in silver taels starting in 1853. In principle, they aimed to substitute for scarce silver in government payments; in practice, convertibility promises were difficult to enforce and acceptance varied. Limited confidence and uneven tax acceptance contributed to rapid discounting in private markets.
In 1853, Taiping forces captured Nanjing, shocking the Qing government and worsening the fiscal crisis. Military spending rose while normal tax collection and silver remittances to Beijing were disrupted. The state turned increasingly to emergency monetary measures to pay troops and officials.
Cut off from key copper supplies during rebellion and war, the Qing government expanded high-denomination coin issues (including large-value cash coins) and also experimented with metals like iron and zinc. When coins carried high face values but low intrinsic metal value, counterfeiting and public mistrust rose. These policies weakened the credibility of official money and accelerated depreciation.
As the state continued printing and circulating paper notes to meet wartime spending, the market value of both cash and tael notes fell sharply. Discounts reflected weak convertibility, forced circulation practices, and doubts about the government’s ability to redeem notes. The result was a widening gap between official face values and real purchasing power.
By 1859, the Great Qing Treasure Notes had effectively lost credibility and were ended as a policy, and by 1861 the Qing government abandoned the main Xianfeng-era paper-money experiment. The collapse did not solve the underlying fiscal problems, but it pushed monetary practice back toward older silver-and-cash arrangements. This outcome showed that state paper credit, without reliable redemption and stable revenues, could deepen monetary strains instead of easing them.
