With fractional reserve banking it is even better, as credit effectively creates money out of thin air. This increases the overall supply of money in an economy, so banks can make money from other sources when that money is spent (e.g. credit card processing fees). The loans are considered assets of the bank, so still increases it's value. And if the loan ends up in an account on their books (there's not that many banks in Denmark), they can then loan out that money again minus the fraction they need to hold.
