Financial Transactions in 2019 - Country by Country

Given that the Bank for International Settlements provides a country by country breakdown of where the financial transactions, this allows me to produce the following table with the value of transactions in each country.

As you can see, the US is responsible for just over one quarter of all the transactions. Next comes the UK, then CLS group (which appears to be a truly global player), and then China and Japan. 

But it is interesting to see that even some relatively small countries like Belgium can be major players, with some $633 trillion in transactions. 

The following table provides a detailed breakdown for the US, the UK, and four Eurozone countries (Belgium, France, Germany and Italy).  Note that all the values are given in USD for ease of comparison.
