That is not really a big amount compared to it's competitors, like SWIFT. ---> SWIFT handles about $5 trillion per day, or given about 250

business days per year, about $1.25 quadrillion dollars a year. Similarly, CHIPS handles about $400 trillion per year, and Fedwire handles around

$900 trillion per year. SWIFT payment message volumes are usually around 11.5 million per day, giving an average payment size of around

$45,000.
