The ratio of the cash in circulation in relation to the gross domestic product (cash to GDP ratio) is a good indicator of cash usage and payment behavior in an economy. In countries like the United States, increased use of debit and credit cards is increasing the amount of cash in circulation at a slower rate than in countries with a high amount of cash payments. In 2018, it ranged from 1.3% (in Sweden) to more than 21% (in Japan), 10.5% in Switzerland and 10.7% in the eurozone.
