Regulations likely wouldn't have prevented JPMorgan's $2 billion trading loss, be they existing regulations or proposed new ones, says real estate mogul Donald Trump.

The bank made a mistake, just like any company does, and is paying for it today.

It's working through the issues and will hopefully come out a better company.

"In theory we have tremendous regulations, probably more than any country in the world as far as banking is concerned and it didn't stop this $2 billion loss," Trump tells CNBC.

"Sometimes you make deals that don't work out so well."

Meanwhile, JPMorgan CEO Jamie Dimon will likely survive the loss, the result of a hedging strategy gone wrong.

"Jamie is a good guy and he is a great banker and he will recover," Trump says.

Regulations, meanwhile, tend to hamper commerce, as banks and other financial institutions spend more time dealing with compliance outlined under legislation such as the Dodd-Frank financial reform law and less time financing businesses, smaller ones especially.

"All that's going to do is stop people from making loans," Trump says.

"If you're looking to start a business, believe me, those poor guys — they can't get money no matter what they do."

"Today I think a startup is virtually impossible. If you go to a bank and you ask for money, I don't think banks loan to startups, and those are the companies that really ultimately built this country."

One of the issues at hand involves the Volcker Rule, a proposal outlined in the Dodd-Frank reform law that would prevent banks from trading securities with their own money.

The Volcker Rule, named for former Federal Reserve Chairman Paul Volcker, has yet to be implemented, but questions have arisen as to whether the trade in question would have violated the rule were it in effect.

Dimon himself has said the trade didn't violate the Volcker Rule due to the technical and hedging nature of the operation, as the loss didn't stem from a proprietary trade.

"This trading may not violate the Volcker Rule but it violates the Dimon principle," Dimon told NBC News just after the news broke of the massive trading loss.

Dodd-Frank co-author Barney Frank, a Massachusetts Democratic representative, was quick to call for the rule's implementation after news of the loss broke.

"I hope that the final rule will prevent this," Frank tells ABC News. "The Volcker Rule is still being formulated."

When reports of the loss broke, Fitch Ratings cut JPMorgan's credit rating to A-plus from AA-minus, and some analysts worry if other banks may find themselves in the spotlight.

"You have seen risk coming off here," says MacNeil Curry, chief rates and currency technical strategist at Bank of America Merrill Lynch, according to Reuters.

"It raises the question that if JPMorgan is the best of the breed, what are the other guys doing?"
