Overdraft - United States - Transaction Processing Order

Transaction Processing Order

An area of controversy with regards to overdraft fees is the order in which a bank posts transactions to a customer's account. This is controversial because largest to smallest processing tends to maximize overdraft occurrences on a customer's account. This situation can arise when the account holder makes a number of small debits for which there are sufficient funds in the account at the time of purchase. Later, the account holder makes a large debit that overdraws the account (either accidentally or intentionally). If all of the items present for payment to the account on the same day, and the bank processes the largest transaction first, multiple overdrafts can result.

The "biggest check first" policy is common among large U.S. banks. Banks argue that this is done to prevent a customer's most important transactions (such as a rent or mortgage check, or utility payment) from being returned unpaid, despite some such transactions being guaranteed. Consumers have attempted to litigate to prevent this practice, arguing that banks use "biggest check first" to manipulate the order of transactions to artificially trigger more overdraft fees to collect. Banks in the United States are mostly regulated by the Office of the Comptroller of Currency, a Federal agency, which has formally approved of the practice; the practice has recently been challenged, however, under numerous individual state deceptive practice laws.

Bank deposit agreements usually provide that the bank may clear transactions in any order, at the bank's discretion.
