I have not worked for the US market the last five years, but as far as I remember there is a law in the US that a bank cannot take adverse action on a existing customer holding the bank's product based on credit history from another bank - so for example, my bank cannot decrease the limit of a card because the customer defaulted in a personal loan held with another bank. Of course, at the time of origination of the credit card, we can use this information. The whole point being that just because data is available does not mean I can use it even though it may be statistically significant for me to use it. Again, I am not sure of insurance regulations so there may be a possibility around using more data, if available, in insurance models.
