Since we have two separate applications, do we need to send bank statements for both of us, or is just one of us enough?
You and your wife applied individually, as required, and will transmit your applications together. The UK supporting documents guidance notes that those applying as a family/group you do not need to provide multiple copies of the same documents.
However, as you note, you and your wife have separate financial records and, thus, they are not the same and both should be submitted, supporting the information provided in each application (and as cross-referenced in the UKVI system).
