China’s widespread quarantine policy thanks to the coronavirus had been expanded from the city of Wuhan to a dozen other cities in Hubei province, to community quarantines for people returning from holiday, and now even inanimate objects must be quarantined. Paper currency, that is.
People’s Bank of China representatives said at a press conference on February 15 that currency deposited at banks must be disinfected with ultraviolet light and then held for a week or longer before being released back into the wilds of the economy. The Chinese central bank will provide new bills worth 600 billion yuan to banks. (Some of the currency will be destroyed.)
Those who work closely with cash are keenly aware of how filthy money is. “When I’m at work, I realize cash is the dirtiest thing in the world,” Wang Zeyaun, a bank teller in Hangzhou, says.
It’s true. A 2002 study of American $1 bills found bacteria on over 90 percent, and a Swiss study found that the flu virus can survive from between a few days and two weeks on francs. (Metal coins are not as dirty as fabric bills.) Richard W. Rahn, a senior fellow at the Cato Institute, hopes that paper currency will disappear.
