Many (all?) banks keep financial transaction records for way longer than what is legally required. Thankfully, most banks are technically incompetent and are unable to easily use data that is not relatively recent. In fact, one bank I worked for had to load transactions from a CD-ROM archive which contained all the transactions in a printable text format (the same format as their printed bank statements). Multiple CDs per day, with no indexing or identification beyond the date. Trying to find a specific 10 year old transaction was very hard work indeed.
