Today's selection-- from Debt by David Graber. Across historical periods, governments and societies have oscillated between metal coinage and credit-based systems.

“The easiest way to make these cycles visible is to reexamine exactly the phenomenon we've been concerned with over the course of this book: the history of money, debt, and credit. The moment we begin to map the history of money across the last five thousand years of Eurasian history, startling patterns begin to emerge. In the case of money, one event stands out above all others: the invention of coinage. Coinage appears to have arisen independently in three different places, almost simultaneously: on the Great Plain of northern China, in the Ganges river valley of northeast India, and in the lands surrounding the Aegean Sea, in each case, between roughly 600 and 500 BC. This wasn't due to some sudden technological innovation: the technologies used in making the first coins were, in each case, entirely different. It was a social transformation. Why this happened in exactly this way is an historical mystery. But this much we know: for some reason, in Lydia, India, and China, local rulers decided that whatever longstanding credit systems had existed in their kingdoms were no longer adequate, and they began to issue tiny pieces of precious metals—metals that had previously been used largely in international commerce, in ingot form—and to encourage their subjects to use them in day-to-day transactions.

“From there, the innovation spread. For more than a thousand years, states everywhere started issuing their own coinage. But then, right around 600 AD, about the time that slavery was disappearing, the whole trend was suddenly thrown into reverse. Cash dried up. Everywhere, there was a movement back to credit once again.

“If we look at Eurasian history over the course of the last five thousand years, what we see is a broad alternation between periods dominated by credit money and periods in which gold and silver come to dominate—that is, those during which at least a large share of transactions were conducted with pieces of valuable metal being passed from hand to hand.

“Why? The single most important factor would appear to be war. Bullion predominates, above all, in periods of generalized violence. There's a very simple reason for that. Gold and silver coins are distinguished from credit arrangements by one spectacular feature: they can be stolen. A debt is, by definition, a record, as well as a relation of trust. Someone accepting gold or silver in exchange for merchandise, on the other hand, need trust nothing more than the accuracy of the scales, the quality of the metal, and the likelihood that someone else will be willing to accept it. In a world where war and the threat of violence are everywhere—and this appears to have been an equally accurate description of Warring States China, Iron Age Greece, and pre-Mauryan India—there are obvious advantages to making one's transactions simple. This is all the more true when dealing with soldiers. On the one hand, soldiers tend to have access to a great deal of loot, much of which consists of gold and silver, and will always seek a way to trade it for the better things in life. On the other, a heavily armed itinerant soldier is the very definition of a poor credit risk. The economists' barter scenario might be absurd when applied to transactions between neighbors in the same small rural community, but when dealing with a transaction between the resident of such a community and a passing mercenary, it suddenly begins to make a great deal of sense.

“For much of human history, then, an ingot of gold or silver, stamped or not, has served the same role as the contemporary drug dealer's suitcase full of unmarked bills: an object without a history, valuable because one knows it will be accepted in exchange for other goods just about anywhere, no questions asked. As a result, while credit systems tend to dominate in periods of relative social peace, or across networks of trust (whether created by states or, in most periods, transnational institutions like merchant guilds or communities of faith), in periods characterized by widespread war and plunder, they tend to be replaced by precious metal. What's more, while predatory lending goes on in every period of human history, the resulting debt crises appear to have the most damaging effects at times when money is most easily convertible into cash.

“As a starting point to any attempt to discern the great rhythms that define the current historical moment, let me propose the following breakdown of Eurasian history according to the alternation between periods of virtual and metal money. The cycle begins with the Age of the First Agrarian Empires (3500-800 BC), dominated by virtual credit money. This is followed by the Axial Age (800 BC-600 AD), which will be covered in the next chapter, and which saw the rise of coinage and a general shift to metal bullion. The Middle Ages (600-1450 AD), which saw a return to virtual credit money, will be covered in Chapter Ten; Chapter Eleven will cover the next turn of the cycle, the Age of Capitalist Empires, which began around 1450 with a massive planetary switch back to gold and silver bullion, and which could only really be said to have ended in 1971, when Richard Nixon announced that the U.S. dollar would no longer be redeemable in gold. This marked the beginning of yet another phase of virtual money, one which has only just begun, and whose ultimate contours are, necessarily, invisible. Chapter Twelve, the final chapter, will be devoted to applying the insights of history to understanding what it might mean and the opportunities it might throw open.”
