Ratio of currency in circulation (CIC) to GDP of the UK 2012-2021
Coins and banknotes not held by banks in the United Kingdom made up slightly more than three percent of GDP in 2021, a percentage that only increased in 2020. This so-called CIC/GDP ratio roughly measures the use of cash money in the country. Due to the anonymity of cash transactions, sources struggle to find exact volumes on this. The ratio mentioned here is quite popular in that regards, as the data it needs is relatively easy to find. Some industry experts mention, however, that this ratio is too general and not necessarily reflects retail payments.
