I could be wrong, but I believe bank checks are treated as cash because they are certified by the originating bank. They aren't like a regular check. They are considered to be a cash equivalent because it was issued by a licensed banking entity with a charter. I am pretty sure the funds clear immediately, or could be made available immediately with a request to the depositing bank. UPDATE - It seems this used to be true (or they would clear next day) but this has changed after an increase in fraudulent checks so many banks now wait until the check actually clears the originating institution.
