More (#1) from The Ascent of Money:

The Amsterdam Exchange Bank (Wisselbank) was set up in 1609 to resolve the practical problems created for merchants by the circulation of multiple currencies in the United Provinces, where there were no fewer than fourteen different mints and copious quantities of foreign coins. By allowing merchants to set up accounts denominated in a standardized currency, the Exchange Bank pioneered the system of cheques and direct debits or transfers that we take for granted today. This allowed more and more commercial transactions to take place without the need for the sums involved to materialize in actual coins. One merchant could make a payment to another simply by arranging for his account at the bank to be debited and the counterparty’s account to be credited. The limitation on this system was simply that the Exchange Bank maintained something close to a 100 per cent ratio between its deposits and its reserves of precious metal and coin. As late as 1760, when its deposits stood at just under 19 million florins, its metallic reserve was over 16 million. A run on the bank was therefore a virtual impossibility, since it had enough cash on hand to satisfy nearly all of its depositors if, for some reason, they all wanted to liquidate their deposits at once. This made the bank secure, no doubt, but it prevented it performing what would now be seen as the defining characteristic of a bank, credit creation.

And:

If the South had managed to hold on to New Orleans until the cotton harvest had been offloaded to Europe, they might have managed to sell more than £3 million of cotton bonds in London. Maybe even the risk-averse Rothschilds might have come off the financial fence. As it was, they dismissed the Erlanger loan as being ‘of so speculative a nature that it was very likely to attract all wild speculators . . . we do not hear of any respectable people having anything to do with it’. The Confederacy had overplayed its hand. They had turned off the cotton tap, but then lost the ability to turn it back on. By 1863 the mills of Lancashire had found new sources of cotton in China, Egypt and India. And now investors were rapidly losing faith in the South’s cotton-backed bonds. The consequences for the Confederate economy were disastrous.

With its domestic bond market exhausted and only two paltry foreign loans, the Confederate government was forced to print unbacked paper dollars to pay for the war and its other expenses, 1.7 billion dollars’ worth in all. Both sides in the Civil War had to print money, it is true. But by the end of the war the Union’s ‘greenback’ dollars were still worth about 50 cents in gold, whereas the Confederacy’s ‘greybacks’ were worth just one cent, despite a vain attempt at currency reform in 1864. The situation was worsened by the ability of Southern states and municipalities to print paper money of their own; and by rampant forgery, since Confederate notes were crudely made and easy to copy. With ever more paper money chasing ever fewer goods, inflation exploded. Prices in the South rose by around 4,000 per cent during the Civil War. By contrast, prices in the North rose by just 60 per cent. Even before the surrender of the principal Confederate armies in April 1865, the economy of the South was collapsing, with hyperinflation as the sure harbinger of defeat.

The Rothschilds had been right. Those who had invested in Confederate bonds ended up losing everything, since the victorious North pledged not to honour the debts of the South. In the end, there had been no option but to finance the Southern war effort by printing money. It would not be the last time in history that an attempt to buck the bond market would end in ruinous inflation and military humiliation.

The Medici Bank is pretty interesting. A while ago I wrote https://en.wikipedia.org/wiki/Medici_Bank on the topic; LWers might find it interesting how international finance worked back then.
