Jamie Dimon, CEO of JP Morgan Chase, is making headlines today with his controversial call for the deregulation of U.S. banks. His latest rally cry urges America to pull out of Basel III, the incoming international bank rules for functioning in international markets.

Basel regulations were created in response to deficiencies in financial regulations exposed by the global financial crisis.

"The Basel III capital rules are designed to make the financial system safer by making banks build up risk-absorbent 'core tier one' capital to at least 7 per cent of risk-weighted assets. The biggest, including JPMorgan, have to reach 9.5 per cent." (via Financial Times)

"Regulators say all countries compromised on agreeing to the rules, which put eight banks -- five from outside the U.S. -- in the top level of capital."

An outspoken Dimon is calling the rules "blatantly anti-American," claiming the imposition of an additional charge to be an overreaction, and an overcorrection for American banks. "I think any American president, secretary of Treasury, regulator or other leader would want strong, healthy global financial firms and not think that somehow we should give up that position in the world and that would be good for your country."

Critics are weighing in on both side of the debate. According to John Carney, Senior Editor at CNBC, Dimon's criticisms don't go far enough, particularly with regard to covered bonds, the focal point of Dimon's argument.

"Since Basel III restricts how banks operate and finance themselves, giving an advantage to covered bonds will give an advantage to European banks that already own the bonds."

But the prospect of deregulation also has many on edge. Those against it are quick to point out how easily deregulated bank structures helped to bring about the financial crisis.

"Let's not have short memories. It's not an excess of capital and regulation that provoked the crisis that we are still suffering from," said European Union Internal Markets Commissioner Michel Barnier. (via The Economic Times)

Be that as it may, his declarations raise an interesting set of questions about the relationship between U.S. banks and regulators. Do you think banks have won the war against regulators?
