Buffett's "time bomb" goes off on Wall Street

By James B. Kelleher - Analysis

CHICAGO (Reuters) - On Main Street, insurance protects people from the effects of catastrophes.

But on Wall Street, specialized insurance known as a credit default swaps are turning a bad situation into a catastrophe.

When historians write about the current crisis, much of the blame will go to the slump in the housing and mortgage markets, which triggered the losses, layoffs and liquidations sweeping the financial industry.

But credit default swaps -- complex derivatives originally designed to protect banks from deadbeat borrowers -- are adding to the turmoil.

"This was supposedly a way to hedge risk," says Ellen Brown, the author of the book "Web of Debt."

"I'm sure their predictive models were right as far as the risk of the things they were insuring against. But what they didn't factor in was the risk that the sellers of this protection wouldn't pay ... That's what we're seeing now."

Brown is hardly alone in her criticism of the derivatives. Five years ago, billionaire investor Warren Buffett called them a "time bomb" and "financial weapons of mass destruction" and directed the insurance arm of his Berkshire Hathaway Inc (BRKa.N) to exit the business.

LINKED TO MORTGAGES

Recent events suggest Buffett was right. The collapse of Bear Stearns. The fire sale of Merrill Lynch & Co Inc MER.N. The meltdown at American International Group Inc (AIG.N). In each case, credit default swaps played a role in the fall of these financial giants.

The latest victim is insurer AIG, which received an emergency $85 billion loan from the U.S. Federal Reserve late on Tuesday to stave off a bankruptcy.

Over the last three quarters, AIG suffered $18 billion of losses tied to guarantees it wrote on mortgage-linked derivatives.

Its struggles intensified in recent weeks as losses in its own investments led to cuts in its credit ratings. Those cuts triggered clauses in the policies AIG had written that forced it to put up billions of dollars in extra collateral -- billions it did not have and could not raise.

EASY MONEY

When the credit default market began back in the mid-1990s, the transactions were simpler, more transparent affairs. Not all the sellers were insurance companies like AIG -- most were not. But the protection buyer usually knew the protection seller.

As it grew -- according to the industry's trade group, the credit default market grew to $46 trillion by the first half of 2007 from $631 billion in 2000 -- all that changed.
