China’s eight centuries of experiment with paper money is coming to a close

From 15MB, February 9:
The Chinese were first with the great transition from commodity money to paper money. They had the necessary technologies (you can’t have paper money without paper and you can’t do it at scale without printing) and, more importantly, they had the bureaucracy. In 1260, the new Emporer Kublai Khan  determined that it was a burden on commerce and drag on taxation to have all sorts of currencies in use, ranging from copper coins to iron bars, to pearls to salt to gold and silver, so he decided to implement a new currency. The Khan decided to replace metal, commodities, precious jewels and specie with a paper currency. A paper currency! Imagine how crazy that must have sounded! Replacing actual stuff with apparently worthless paper! It’ll never work!

Crazy or not, it worked and just as Marco Polo and other medieval travellers returned along the Silk Road breathless with astonishing tales of paper money, so modern commentators (e.g., me) are tumbling off of flights from Shanghai with equally astonishing tales of a land of mobile payments, where paper money is vanishing and consumers pay for everything with smartphones. China is well on the way to becoming a cashless society, with the end of paper money in sight. Something like one-seventh of China’s population relies on mobile payments to get around, carrying no cash, according to a survey conducted by Renmin University of China. The natural step from there is to create digital currency so that settlement is in central bank money and there are no credit risks.

This thinking has been evolving for some time. Back in 2016, the Governor of the People’s Bank of China (PBOC), Zhou Xiaochuan, set out the Bank’s thinking about digital currency, saying that it is an irresistible trend that paper money will be replaced by new products and new technologies. He went on to say that as a legal tender, digital currency should be controlled by the central bank and after noting that he thought it would take a decade or so for digital currency to completely replace cash in China, he went to state clearly that the bank was working out “how to gradually phase out paper money”. Rather than simply let the cashless society happen, which may not led to the optimum implementation for society, they were developing a plan for a cashless society.

As I have written before, I don’t think a “cashless society” means a society in which notes and coins are outlawed, but a society in which they are irrelevant. Under this definition the PBOC could easily achieve this goal for China. But should they do this? Yao Qian, from the PBOC technology department wrote on the subject in 2017, saying that to “offset the shock” to commercial banks that would come from introducing an independent digital currency system (and to protect the investment made by commercial banks on infrastructure), it would be possible to “incorporate digital currency wallet attributes into the existing commercial bank account system” so that electronic currency and digital currency are managed under the same account.

This rationale is clear and, well, rational. The Chinese central bank wants the efficiencies that come from having a digital currency but also understands the implications of removing the exorbitant privilege of money creation from the commercial banks. If the commercial banks cannot create money by creating credit, then they can only provide loans from their deposits. Imagine if Bitcoin were the only currency in the world: I’d still need to borrow a few of them to buy a new car, but since Barclays can’t create Bitcoins they can only lend me Bitcoins that they have taken in deposit from other people. Fair enough. But here, as in so many other things, China is a window into the future, because Alipay, WeChat Wallet and other Chinese third party payment platforms use financial incentives to encourage users to take money out of their bank accounts and store it on their platforms. If commercial banks cannot fund loans from deposits, we are in a new place, economically speaking....MORE

Chinese inflation hits 6.5 percent, highest rate in nearly 11 years
...If I recall correctly, the Ming Dynasty had to repudiate paper money in the 1450's to end a hyperinflation.
Update: I am pleased with myself.
Found this quote from "A History of Money":

1448 Hyperinflation in China
The Ming note nominally worth 1,000 cash has a market value of only three.
