The Short Answer
The US banking system was [developed in the 70s](_URL_0_), and has not been updated since. They save up days worth of transactions and then actually perform them all at once, which saves them a lot of effort. If Bank A has 10,000 transactions totaling 1 million dollars to go to bank B, and Bank B has 10,000 transactions totaling $800,000 to go to bank A, it's much easier to add up the transactions and then just send the difference. A single $200,000 transaction is much simpler than 20,000 transactions. They assumed that data transfers would take place by air-mailing data tapes, so a few days delay wouldn't matter much anyway. Data transfers take place by internet now, but they've got no competition to encourage them to modernize—every bank in the country has signed on to this system (they have to, if they want to do business with other banks).
