Deposits are leaving the banking system at a rate of 100 million to 500 million euros ($125 million to $625 million) a day, Kathimerini said, without specifying over how long a period that rate of outflow has continued.
Considering that the Greece banking system has about €170 billion in total deposits, this is roughly 0.3% of the entire deposit base fleeing each day - those who understand the nuances of fractional reserve banking get why this could be an issue.
Putting this in the US context, which has over $8 trillion in various forms of deposits, this would be equivalents to about $25 billion getting withdrawn. Every day.
