Reg CC Holds on Treasury Checks

If the check is deposited to a new account (the customer had not had a transaction account with your bank within 30 days of the first deposit to the account), you can hold the excess over $5,525 in next-day availability checks (including the US Treasury check) for up to 9 business days from the banking day of deposit. The first $5,525 of such checks deposited must be available by the first business day after the banking day of deposit.

If the account is not a new account, and the Treasury check is deposited in an account of a payee of the check, it is a next-day check. If it is deposited in an account of a person who is not a payee of the check, it has no special status. The first $5,525 of next-day checks deposited on a banking day is to be available by the next business day after the banking day of deposit; the rest of the checks deposited must be available by the second day after the banking day of deposit unless the bank places an exception hold.
