The global silver trade between the Americas, Europe and China from the sixteenth to nineteenth centuries was a spillover of the Columbian Exchange which had a profound effect on the world economy. In fact, many scholars consider the silver trade to mark the beginning of a genuinely global economy, with one historian noting that silver "went round the world and made the world go round." [1] Although global, much of that silver ended up in the hands of the Chinese, as they accepted it as a form of currency. [2] In addition to the global economic changes the silver trade engendered, it also put into motion a wide array of political transformations in the early modern era. "New World mines," concluded several prominent historians, "supported the Spanish empire," acting as a linchpin of the Spanish economy. [3]

Spaniards at the time of the Age of Exploration discovered vast amounts of silver, much of which was from the Potosí silver mines, to fuel their trade economy. Potosí's deposits were rich and Spanish American silver mines were the world's cheapest sources of it. The Spanish acquired the silver, minting it into the peso de ocho to then use it as a means of purchase; that currency was so widespread that even the United States accepted it as valid until the Coinage Act of 1857. [4] As the Spanish need for silver increased, new innovations for more efficient extraction of silver were developed, such as the amalgamation method of using mercury to extract silver from ore. [5]

In the two centuries that followed the discovery of Potosí, the Spanish silver mines in the Americas produced 40,000 tons of silver. [6] Altogether, more than 150,000 tons of silver were shipped from Potosí by the end of the 18th century. [7] From 1500 to 1800, Mexico and Peru produced about 80% [8] of the world's silver with 30% of it eventually ending up in China (largely because of British merchants who used it to purchase exotic Chinese commodities). In the late 16th and early 17th century, Japan was also exporting heavily into China and the foreign trade at large. [8]

As has been demonstrated, China dominated silver imports. The market value of silver in the Ming territory was double its value elsewhere, which provided great arbitrage profit for the Europeans and Japanese. [8] The abundance of silver in China made it easy for the country to mint it into coinage. That process was so widespread that local Chinese government officials would demand taxes to be paid in silver to the point that silver eventually backed all of China's economy.

First paper money

The world's first paper money ("flying money") was invented by the Chinese [9] and they needed some commodity to back it. Traditional coins were useful, but the amount of coins needed for large purchases could be bulky and dangerous to transport. That problem was solved when the Chinese created small pieces of paper with pictures of the coin printed on them. [10] By the nature of their geography, China had no real amount of precious metals of their own to back the paper money they invented. Because the Spaniards didn't find gold but did find copious amounts of silver, the Spaniards and the rest of Europe used this silver to purchase the commodities of choice from China, solving both of their problems. [11]

Silver in the Americas

A result of the Spanish colonization of the Americas was the discovery, production, and trade of precious metals. The Spanish, along with other European nations, had a great desire for Chinese goods such as silk and porcelain. [12] The Europeans did not have any goods or commodities which China desired, so they traded silver to make up for their trade deficit. [13] The two most important mining colonies of the Spanish Empire were Peru and Mexico, who were estimated to have provided one-hundred thousand tons of silver from the mid 16th Century to the end of the colonial period. [14] The richest and most productive mine in the Americas was that of Potosí in what is modern day Bolivia. [14] The richest camp in Mexico was in the city of Zacatecas. However, the production of this mine was far less than that of Potosi. [14]

Mining processes in the Americas

Relatively simple native mining techniques dominated American mining for the early part of the 16th Century. [5] Mining in the Americas became formally industrialized when the process of mercury amalgamation became popularized. Mercury amalgamation was invented by a Spaniard in central Mexico in the 1550s. [5] Historians dispute what individual was the first to invent the process, however most agree that it was a Spaniard. Mercury was the one of the highest costs of production for the Americas, since much of it had to be shipped. [14] The ratio of Mercury to silver produced was about two to one. [14] Furthermore, German miners introduced the stamp mill and lead smelting in the 1530s. [5] Gunpowder was often used to blast large holes to create the mine shafts, although there were not many deep shafts. [5] Potosí had the most amount of ore, however it was lower quality than that of Mexico.

Mining production in the Americas largely depended on native labor in both Mexico and Peru. [5] In Mexico, many of the natives worked as wage laborers by the middle of the 17th Century. [15] However, the labor system known as the repartimiento still existed in some places. [15] Silver production in Mexico was relatively cheap when compared to that of Peru, and the general trend of Mexican labor systems was that towards waged labor. [14] In Peru mines, the mit'a system was a dominant form of native labor subjection, although waged laborers worked on the mines as well. [14] Natives under the mit'a system were paid much less, and this was necessary for the production of silver to continue in Peru where costs were relatively high. [14]

Global flow of silver

The ultimate destination for the mass amounts of silver produced in the Americas and Japan was China. [16] Silver from the Americas flowed mostly across the Atlantic and made its way to the far east. [13] A popular route was around the Cape of Good Hope into the east, and sometimes it came over land. [13] Major outposts for the silver trade were located in Southeast Asian countries, such as the Philippines. [17] The city of Manila served as a primary outpost of the exchange of goods between the Americas, Japan, Indian, Indonesia and China. [17] However, there is a large amount of silver that crossed across the Pacific Ocean directly from the Americas as well. [16] There are not many records of the amount of silver which crossed the Pacific due to it being discouraged by the Spanish monarchy, so estimates highly vary. [15]

Silver also found its way across other parts of the world as well. India and Europe both received a fair amount of silver. [13] This silver was often locally traded for other commodities, such as gold or crops. In India, silver flowed from the south to the north, and gold flowed the opposite way. [13] Often silver and gold were manufactured into jewelry or hoarded as treasure.

China and the demand for silver

China was the ultimate destination in which silver would flow towards. In exchange, the Chinese traded their popular goods such as silk and porcelain. China had a high demand for silver due to its shift from paper money to coins in the early period of the Ming Dynasty. [18] The Ming paper currency eventually failed due to self-imposed inflation along with an inability to stop the production of counterfeit bills. [19] The Ming attempted to produce copper coins as a new form of currency, but production was inconsistent. [18] Hence silver became of high value because it was a valid currency that could be processed abroad. The bimetallic ratio of silver to gold was about two to one, which meant that European and Japanese merchants made a large amount of profit. [20] In the 1640s, the bimetallic ratios in China converged with the rest of the world, before experiencing another population boom. [16] The new population boom was a product of the introduction of New World crops into China, mainly sweet potatoes, which could be more easily grown. [16] By this time, the silver mines in Japan were largely depleted and the New World became China's primary source for silver. [17]

Initially, Japan served as China's primary source for silver in the 16th Century. [12] In exchange for silver, China would provide Japan with silk and gold. [17] Japan and China did not directly trade with each other, due to political tensions. [17] This meant that European entities and countries, such as the Dutch and Portuguese served as a middle man between the two countries. [17]

China's silver dominance

In the famed The Wealth of Nations, Adam Smith noted the sheer force and great reach of the global silver trade. He was impressed by its market value but more intrigued with the way this single item of commerce brought together new and old worlds i.e. the Americas and China. [21] Although China acted as the cog running the wheel of global trade, Japan's huge contribution of silver exports to China were critical to the world economy and China's liquidity and success with the commodity. Historians posit Europeans would have been left out of world trade, and China may have fallen prey to conquest by settlers of the Americas, if not for Japanese silver mining. Silver was paramount to East Asia's introduction into the global trade market. [22] Under the Ming and Qing empires, China hoarded silver to boost its economy and increase its trading power. [23]

Many historians argue that silver was responsible for the birth of global economics and trade. According to this view, global trade commenced in 1571 when Manila was founded and became the first trading post linking America and Asia due to the expansive and profitable silver trade. [24] In fact, research shows the amount of silver traveling from Manila to China was approximately three million pesos or 94,000 kilograms in the early 1600s. [25]

The rarity of silver production was seen as an opportunity for China to control the currency's value and support its own national currency. Silver was one of the only accepted trade items from Europeans and its value in China was astronomical compared to rest of the world. In fact, its value was twice that of Spain in the 16th and 17th centuries. [22] Between 1600 and 1800 China received 100 tons of silver on average per year. A large populace near the Lower Yangtze averaged a hundreds of taels of silver per household in the late 16th century. [26]

Silver even played a large role when defending Toyotomi Hideyoshi's attempted take over of Ming-ruled Joseon Korea. The Ming Ministry of War sent approximately 140,000 liang of silver to its soldiers and required provinces to provide silver as tax for the war effort as well. [27] In the sixteenth century, the daimyos of Southwest Japan hoped for unhinged global trade but were stopped due to Ming China trade policies. Still, Japan became a player in the global economy via frequent Ming merchant ships arriving to extract Japan's abundance of silver and exchange goods. Japan increased its wealth through successful trilateral trade with Portugal and China as Japan now had Chinese goods to offer the Portuguese who had silver mines of their own. [28] Founder of the Ming China dynasty, Hongwu, actually sought to eliminate silver from the market due to his fear of inflation which he previously experienced in the Yuan dynasty. His attempt involved imposing harsh limits on silver mining to stop its flow into the market and subsequently replaced it with baochao or paper money. However, the currency never popularized and silver proved its mainstay as a global currency. [29]

Opium Wars

Despite some restrictions, silver continued to drive trade through its popularity in Europe. This, combined with a high British demand for Chinese tea, created chronic trade deficits for European governments, which were forced to risk silver deficits to supply merchants in Asia. [30] As supplies of silver decreased in Europe, Europeans had less ability to purchase highly coveted Chinese goods. Merchants were no longer able to sustain the China trade through profits made by selling Chinese goods in the West and were forced to take bullion out of circulation in Europe to buy goods in China. [31]

In the 19th century, American merchants began to introduce opium to Chinese markets. The demand for opium rose rapidly and was so profitable that Chinese opium dealers began to seek out more suppliers of the drug, thus inaugurating the opium trade; one merchant declared that Opium "is like gold. It can sell any time." [30] From 1804 to 1820, a period when the Qing Dynasty needed to finance the suppression of the White Lotus Rebellion, Chinese merchants were soon exporting silver to pay for opium rather than Europeans paying for Chinese goods with the precious metal. [32]

The Qing imperial court debated whether and how to end the opium trade, eventually settling on regulations on consumption. That measure, however, resulted in an increase in drug smuggling by Europeans and Chinese traders. In 1810, the Daoguang Emperor issued an edict concerning the matter, declaring, "Opium has a harm. Opium is a poison, undermining our good customs and morality. Its use is prohibited by law." [33] Following a debate at court in 1836 on whether to legalize the drug or crack down on its use, the emperor decided on the latter. An upright official, Commissioner Lin Zexu led the campaign against opium as a kind of "drug czar." The British, offended by the seizure of their property in opium, sent a large naval expedition to China to end the restrictive conditions under which they had long traded with that country. Thus began the first Opium War, in which Britain's industrialized military might was proven in China's rout. The Treaty of Nanking, which ended the war in 1842 largely on British terms, imposed numerous restrictions on Chinese sovereignty and opened five ports to European traders. [34]

The Price Revolution, sometimes known as the Spanish Price Revolution, was a series of economic events that occurred between the second half of the 15th century and the first half of the 17th century, and most specifically linked to the high rate of inflation that occurred during this period across Western Europe. Prices rose on average roughly sixfold over 150 years. This level of inflation amounts to 1–1.5% per year, a relatively low inflation rate for modern-day standards, but rather high given the monetary policy in place in the 16th century.

The Haijin or sea ban was a series of related isolationist Chinese policies restricting private maritime trading and coastal settlement during most of the Ming dynasty and some of the Qing.

First Opium War 1839–1842 war between Great Britain and China

The First Opium War, also known as the Opium War or the Anglo-Chinese War, was a series of military engagements fought between Great Britain and the Qing dynasty of China. Chinese officials clamped down on the banned opium trade, and threatened the death penalty to future offenders, causing offence toward the British government. The British dominated the trade and were much stronger militarily. They defeated the Chinese, and imposed a penalty that gave Western powers special privileges to trade with China.

Spanish dollar Former coin of the Spanish Empire

The Spanish dollar, also known as the piece of eight, is a silver coin of approximately 38 mm (1.5 in) diameter worth eight Spanish reales. It was minted in the Spanish Empire following a monetary reform in 1497.

Potosí city in Bolivia

Potosí, called during the colony as "Villa Imperial de Potosí", is the capital city and a municipality of the Department of Potosí in Bolivia. It is one of the highest cities in the world at a nominal 4,090 metres (13,420 ft). For centuries, it was the location of the Spanish colonial silver mint.

Age of Discovery Period of European global exploration

The Age of Discovery, or the Age of Exploration, is an informal and loosely defined term for the period in European history in which extensive overseas exploration emerged as a powerful factor in European culture and which was the beginning of globalization. It also marks the rise of the widespread adoption of colonialism and mercantilism as national policies in Europe. Many lands previously unknown to Europeans were discovered by them during this period, though most were already inhabited. From the perspective of many non-Europeans, the Age of Discovery marked the arrival of invaders from previously unknown continents.

Trade dollars are silver coins minted as trade coins by various countries to facilitate trade with China and the Orient. They all approximated in weight and fineness to the Spanish dollar, which had set the standard for a de facto common currency for trade in the Far East.

Patio process

The patio process is a process for extracting silver from ore. The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas. Other amalgamation processes were later developed, importantly the pan amalgamation process, and its variant, the Washoe process. The silver separation process generally differed from gold parting and gold extraction, although amalgamation with mercury was also sometimes used to extract gold.

Cerro Rico mountain in the Andes near the Bolivian city of Potosí

Cerro Rico, Cerro Potosí or Sumaq Urqu is a mountain in the Andes near the Bolivian city of Potosí. Cerro Rico, which is popularly conceived of as being "made of" silver ore, was famous for providing vast quantities of silver for Spain during the period of the New World Spanish Empire. It is estimated that eighty-five percent of the silver produced in the central Andes during this time came from Cerro Rico. As a result of mining operations in the mountain, the city of Potosí became one of the largest cities in the New World.

Silver coins are possibly the oldest mass-produced form of coinage. Silver has been used as a coinage metal since the times of the Greeks; their silver drachmas were popular trade coins. The ancient Persians used silver coins between 612-330 BC. Before 1797, British pennies were made of silver.

Economic history of Mexico

Mexico's economic history has been characterized since the colonial era by resource extraction, agriculture, and a relatively underdeveloped industrial sector. Economic elites in the colonial period were predominantly Spanish born, active as transatlantic merchants and silver mine owners and diversifying their investments with the landed estates. The largest sector of the population was indigenous subsistence farmers, who lived mainly in the center and south.

Iwami Ginzan Silver Mine mine

The Iwami Ginzan (石見銀山) was an underground silver mine in the city of Ōda, in Shimane Prefecture on the main island of Honshu, Japan. It was the largest silver mine in Japanese history. It was active for almost four hundred years, from its discovery in 1526 to its closing in 1923.

The Cohong, sometimes spelled kehang or gonghang, was a guild of Chinese merchants or hongs who operated the import-export monopoly in Canton during the Qing dynasty (1644–1911). During the century prior to the First Opium War of 1839, trade relations between China and Europe were exclusively conducted via the Cohong, which was formalised by imperial edict in 1760 by the Qianlong Emperor. The Chinese merchants who made up the Cohong were referred to as hangshang (行商) and their foreign counterparts as yanghang.

Economy of the Ming dynasty Economy of China in from the 14th through 17th centuries

The economy of the Ming dynasty (1368–1644) of China was the largest in the world during that period. It is regarded as one of China's three golden ages. The period was marked by the increasing political influence of the merchants, the gradual weakening of imperial rule, and technological advances.

Francisco Pizarro and his fellow conquistadors from the rapidly growing Spanish Empire first arrived in the New World in 1524. But even before the arrival of the Europeans, the Inca Empire was floundering. Pizarro enjoyed stunning successes in his military campaign against the Incas, who, despite some resistance, were defeated and in 1538 the Spaniards completely defeated Inca forces near Lake Titicaca, allowing Spanish penetration into central and southern Bolivia.

The Qing conquest theory is a theory proposed by Chinese academics that attempts to explain the Great Divergence, the overtaking of China by the Western world as the major economic and industrial world power. Specifically, the theory seeks to explain how Europe could experience an industrial revolution, but China did not. Theory supporters claim that although the prosperous Song and Ming dynasties moved China toward a modern age, the restrictions placed on commerce and industry and the persecution of non-orthodox thought after the Manchu conquest of China caused the country to stagnate and fall behind the West.

The Single Whip Law or the "Single Whip Reform" was a fiscal law first instituted during the middle Ming dynasty, in the early 16th century, and then promulgated throughout the empire in 1580 by Zhang Juzheng.

The Great Bullion Famine was a shortage of precious metals that struck Europe in the 15th century, with the worst years of the Famine lasting from 1457 to 1464. During the Middle Ages, gold and silver coins saw widespread use as currency in Europe, and facilitated trade with the Middle East and Asia; the shortage of these metals therefore become a problem for European economies. Many causes for the famine have been proposed, such as the Hundred Years' War (1337–1453), depopulation and poor agricultural output due to the aftermath of the Black Death (1346–1353), and an outflow of silver to the east unmatched by mining output. The Late Middle Ages particularly saw a deficit in silver rather than gold.

Latin American economy

Latin America as a region has multiple nation-states, with varying levels of economic complexity. The Latin American economy is an export-based economy consisting of individual countries in the geographical regions of North America, Central America, South America, and the Caribbean. The socioeconomic patterns of what is now called Latin America were set in the colonial era when the region was controlled by the Spanish and Portuguese empires. Up until independence in the early nineteenth century, colonial Latin American regional economies boomed. Many parts of the region had favorable factor endowments of deposits of precious metals, mainly silver, or tropical climatic conditions and locations near coasts that allowed for the development of cane sugar plantations. In the nineteenth century following independence, many economies of Latin America declined. In the late nineteenth century, much of Latin America was integrated into the world economy as an exporter of commodities. Foreign capital investment, construction of infrastructure, such as railroads, growth in the labor sector with immigration from abroad, strengthening of institutions, and expansion of education aided industrial growth and economic expansion. A number of regions have thriving economies, but "poverty and inequality have been deeply rooted in Latin American societies since the early colonial era."
