Not at all- it's similar to the Real Estate Agent problem that is described in detail in Freakonomics. The bank has some slightly higher interest in raising the price and getting more money- but a much higher interest in offloading as much security as possible. This has led to problems like banks selling to specific IPO turnaround firms that can grab huge share volume early on, sending the IPO up in value before selling out right near close of trading, sometimes trashing hot IPOs on day 1.
