No, it has the opposite effect on me, a bank employee, to immediately report everything weird because even if I do nothing wrong, want banks to behave legally, and have never personally traded a stock in my life, the appearance of impropriety is just as bad as actual dishonesty. Never did it make me think I could just as well front run clients with a secret account since forgetting to disclose an old account I never used was bad too. I declared late that old account and apologized instead, for instance. I think these rules are, like all rules, also mostly to draw responsibilities in case of trouble: they do nothing to prevent a criminal to crime, but once the crime is done, he cant claim he did everything by the book if the book was so clear.
