We've been tracking the developments in account-to-account transfers closely, in preparation for an upcoming Online Banking Report on the subject. It's tough to get a handle on the actual dollar volumes, so we were pleased to see American Banker's Daniel Wolfe quantify the market size.

In Friday's article (subscription required), MasterCard's TowerGroup payments analyst, Beth Robertson is quoted as saying that in 2004, $730 billion was transferred via account-to-account transfer (i.e., a funds transfer from an individual's account at one financial institution to the same customer's account at another). That amounts to more than $7000 for each of approximately 100 million U.S. households. All but a billion or so was initiated off-line.

But the online portion is growing. CashEdge the leading supplier of online account-to-account transfers, expects to process $6 billion in 2005, that's about $200 annually for each of the 30 million or so U.S. online banking households. However, fewer than 50% of those households have access to online account-to-account transfers.
