If I make a purchase with my debit card on Friday, it takes two business days to show up on my online statement (i.e. it shows up on Tuesday). On any other day, it takes one business day.
I’m not even really sure why it shouldn’t take zero business days for most transactions. But what about that two-business-day thing over weekends? Is that common to all banks? Or do I just have a slow bank?
I should note when I say “show up” I mean it appears under what it calls the “processed transactions” part of the online statement. It will also have sat in the “unprocessed transactions” part from the time of purchase until it gets processed. But transactions in “unprocessed” don’t get downloaded when I download the statement, and it’s a good thing because they are occasionally (but often enough to matter) inaccurate until they get processed.
