One of my colleagues sent around a bloomberg article which stated that Westpac (the Aussie bank) had opined that the Basel 3 rules were flawed and risked constraining lenders! Wasn't it unconstraining lending that help get us into the GFC (global financial crisis for non-aussies)?
Why anyone would care what any bank thought of attempts to regulate it remains beyond me. One of the major problems of Basel 2 was that banks were allowed to use their own risk models to value assets. This is akin to asking kids to mark their own homework, one shouldn't be surprised when they report they got 100% correct.
Talk about not learning from mistakes. Hasn't anyone heard of regulatory capture?
