Some fintech companies have stated that banks are not following through on the data sharing guidance set forth by the CFPB; banks on the other hand have said they are following through and sharing data with fintechs; the biggest complaint thus far is that banks are being selective and not granting access widely; banks have more complicated systems and multiple levels of compliance which could end a relationship before it begins; some ideas for better cooperation are for banks to design a set of standards as banks in the UK have done.
