The last statistics that I saw indicated the average return time for a local check was 2.2 days. For a nonlocal check, the average return time was 5.5 days. On two occasions, the Fed went to Congress and asked that they increase the case by case hold periods to 3 and 6 days for local and nonlocal checks respectively.
Congress was clearly unimpressed. Regulation CC is a consumer protection law, it was never intended to assure that the banks got an even break. Accordingly, only the exception holds provide any significant amount of protection.
