Your Honor, can I sue the bank regulators?

Your Honor, 

My small riskier less creditworthy business always got less credit and paid higher interest rates than the more creditworthy, and that was ok. 

But the regulators, with their risk weighted bank capital requirements, also decreed it to be less worthy of credit and, since it now has to compensate the banks for these not being able to leverage as much their capital/equity as much as they can with other “safer” assets, they made it get even less credit and pay even higher interests. 

Can I sue them?
