The point about the CRA still stands, as only one bank applied for CRA credit for their subprime mortgage loans. If the CRA was driving these loans more banks would have applied for CRA credit as a result of making subprime loans.
Also secondary markets can easily drive primary markets. It's fair to say the investment banks were the main players in the subprime crisis because they were the ones buying up bad loans at incredible rates.
The reasons the initial lenders didn't care about making bad loans is they knew they could sell the toxic capital at a profit. As long as they aren't left holding toxic assets and made money at some point along the process they would continue to make these loans.
In summary, initial lenders made bad loans because there was a market for them, not because they had to under some policy. These loans were sold at a profit to investment banks, who believed these instruments to be profitable (which they were until the housing prices underwent cascade failure).
The problem was the investment banks were allowed to leverage exorbitantly. Previous caps of 5 to 1 leveraging under regulation were replaced by exemptions allowing 50 to 1 leveraging. This meant a hugely profitable company that forms a critical part of the banking sector could be instantly bankrupt due to a small price drop in the housing market (If one is leveraged 50 to 1 on an asset that drops 5% one is bankrupt twice over).
This leveraging process allowed the investment banks to continue to "free up capital" to buy excessive amounts of subprime loans, and with the market for loans available, banks continued to make them. Bundled instruments ended up preventing a lot of examining of the quality of individual loans by investors, and as such the initial lenders got away with having frighteningly bad standards for loans. Again, this was a sound business practice because they were able to sell these loans at a profit easily, not dealing with the consequences of them being bad loans.
