I was curious, and the American Clearing House has a TPV of $93 trillion, which means ACH is 78%?? That seems too high.

Oh - not all bank transfers count in GDP. I often move money from one account to another.

Note that Visa has the same issue: withdrawing money from an ATM shouldn’t count towards GDP! Neither does Vemo-ing a friend to settle up a split restaurant bill (my Venmo is attached to my debit card).
