Latest / The Atlantic Slave Trade: Empire Built on Human Suffering — Fexingo History / The Secret Currency of the Slave Trade
Transcript
- Lucas: For anyone coming with us through these conversations about the Atlantic world, we’ve spent a lot of time talking about the violence of the middle passage and the legal frameworks that allowed it. But there’s a quieter, more insidious layer to this story that doesn’t involve chains or whips, but rather ledgers and credit lines. Today, I want to talk about how the slave trade became a financial instrument, traded and leveraged in the counting houses of London long before the ships ever left port. Luna: So you’re saying the money trail is just as important as the human one? Lucas: Exactly. It’s about how abstract the suffering became when it was converted into interest rates and mortgages. To understand this, we have to go back to the mid-seventeenth century, specifically to the reign of Charles II. In 1660, he granted a royal charter to the Royal African Company, giving them a monopoly on English trade along the West African coast. They weren’t just selling gold and ivory anymore; they were exclusively authorized to supply enslaved laborers to the British colonies in the Americas. Lucas: Now, this sounds like a straightforward business deal, but it wasn’t. The Royal African Company was backed by the crown, which meant it had access to state resources, but it also carried enormous political risk. When James II took over in 1685, he tried to expand their power aggressively, using naval force to crush competitors. This created a backlash among independent merchants who felt shut out, and it eventually led to the Glorious Revolution, where James was ousted. Luna: And that political shift changed how the trade was financed? Lucas: It did, but the real shift happened later, in the early eighteenth century, when the monopoly was broken. Independent merchants from Bristol, and later Liverpool, flooded into the trade. They didn’t have the king’s navy backing them, so they needed a different kind of support. That support came from the City of London’s banks, particularly the emerging institutions that would eventually become part of the Bank of England’s ecosystem. These merchants started treating enslaved people as liquid assets. Lucas: Here is where it gets really dark and really specific. Merchants would borrow money against the future value of the enslaved people they intended to buy. They issued what are known as slaver bills—essentially promissory notes that promised repayment once the cargo arrived in the Caribbean and was sold. If the ship sank, the debt remained. If the enslaved people died of disease, the debt remained. The financial risk was detached from the human cost. Luna: That sounds incredibly cynical, treating life like a futures contract. Lucas: It was. And some of the most prominent figures in British history were deeply involved in this machinery. Take Edward Colston, for example. He was a governor of the Royal African Company and a major shareholder. His wealth, which he later donated to various charities in Bristol, was built directly on the sale of roughly twelve thousand enslaved Africans. His name is still controversial today, not just for the brutality of the trade, but for how seamlessly philanthropy was funded by exploitation. Lucas: Colston wasn’t an outlier; he was a symptom. As the trade grew, so did the financial infrastructure. Banks in London began accepting shares in slave voyages as collateral for loans. This meant that even people who never set foot in Africa or the Americas could indirectly profit from the trade by borrowing against it. The entire economy of Britain started to lean on this unstable foundation. Luna: Did the Bank of England itself get involved in this? Lucas: Yes, and this is a crucial point that many people miss. The Bank of England, founded in 1694, was essentially created to finance government war debts, but it quickly became intertwined with commercial ventures, including the slave trade. The governors of the bank were often merchants with direct ties to the West Indies. There are records of the bank discounting bills of exchange that were explicitly tied to slave cargoes. They were providing the liquidity that kept the trade moving. Lucas: Let’s look at the mechanics of a typical voyage. A merchant in Liverpool would approach a banker for a loan of five hundred pounds. The banker would require collateral. The merchant might pledge his house, or he might pledge the anticipated profits from a slave ship. The banker would then issue a note, which the merchant could use to buy supplies or pay for captives in Africa. Once the ship returned, the sale of the enslaved people would repay the loan plus interest. It was a closed loop of capital and human misery. Luna: So the debt was guaranteed by human lives? Lucas: In effect, yes. And because the trade was so profitable, banks were eager to lend. Interest rates for slave voyages were often lower than for other types of trade because the expected returns were so high. This incentivized even more lending, which led to more voyages, which led to more enslavement. It was a self-reinforcing cycle that made abolition economically difficult for those who were invested in the system. Lucas: This financial entanglement is why abolition didn’t happen overnight. Even as moral arguments grew stronger, the economic interests were too deeply woven into the fabric of British society. You had politicians, bankers, and merchants all tied together by these slaver bills. Breaking that chain required not just moral outrage, but a complete restructuring of the global financial system. Luna: It makes me wonder how many people knew about this connection back then. Lucas: Most people probably didn’t know the details, but they certainly saw the results. The prosperity of cities like Liverpool and Bristol was visible everywhere. The grand buildings, the public parks, the museums—they were all paid for with this blood money. Abolitionists like William Wilberforce argued that the trade was morally bankrupt, but they were up against an economic powerhouse that claimed the trade was essential for the nation’s wealth. Lucas: One interesting detail is how the insurance industry got involved. Lloyd’s of London, which we now associate with marine insurance, began offering policies for slave ships. These policies covered the loss of the vessel, but also the loss of the 'cargo,' meaning the enslaved people. So, insurers were profiting from the deaths of hundreds of people. If a ship sank or the captives died of smallpox, the insurance payout helped cover the merchant’s losses, further insulating them from the consequences of their actions. Luna: That level of detachment is hard to comprehend. Lucas: It is. It required a profound moral blind spot. To see a human being and immediately calculate their market value, their insurability, and their utility as collateral, is a dehumanization process that went hand-in-hand with the physical violence of the trade. The financial system didn’t just facilitate slavery; it encouraged it by making it less risky for the perpetrators. Lucas: As the nineteenth century approached, the tide began to turn. The Napoleonic Wars disrupted trade, and the abolitionist movement gained momentum. When the British Parliament finally passed the Slavery Abolition Act in 1833, it included a massive compensation package for slave owners. Surprisingly, the financiers and bankers who had lent money against the slaves also sought compensation for their lost collateral. The financial legacy of the trade lingered long after the chains were removed. Luna: So the banks wanted to be paid for the people they never owned? Lucas: Precisely. They claimed they had lost the value of the assets they had financed. It was a staggering assertion of entitlement. The fact that the British government agreed to pay millions in compensation—funded by national debt—shows just how deeply embedded the trade was in the state’s finances. It wasn’t just a private enterprise; it was a pillar of the nation’s economy. Lucas: Understanding this financial dimension changes how we view the era. It wasn’t just a group of cruel merchants shipping people across the ocean. It was a sophisticated global network of banks, insurers, and investors who treated human beings as commodities in a way that feels disturbingly familiar. The mechanisms of credit and leverage are still with us today. Luna: It makes you question the foundations of modern finance. Lucas: It should. History isn’t just about what happened; it’s about how the structures we live in today were built. The Atlantic slave trade wasn’t an aberration; it was a driver of modern capitalism. By understanding the money, we can better understand the power dynamics that continue to shape our world. Luna: That’s a heavy but necessary perspective.
