Bank losses from monolines seen up to $7 billion: analyst

NEW YORK (Reuters) - Financial institutions are likely to take only around $5 billion to $7 billion in losses from their exposure to bond insurers, far below recent estimates of as much as $70 billion, Morgan Stanley said on Monday.

Morgan Stanley also said a bailout of the bond insurance industry is not in the economic interest of banks, though analysts at CreditSights said late on Sunday they now view a bailout as more likely.

Monoline bond insurers are under review by credit ratings agencies and may lose the "AAA" ratings vital to their business.

Rating agencies do not view the bond insurers' capital as adequate due to expected losses from insuring securities linked to the subprime mortgage market where defaults have risen.

Some analysts have said they believe U.S. financial institutions exposed to the bond insurers are facing as much as $50 billion to $70 billion in losses, but Greg Peters, Morgan Stanley's lead credit analyst, said he views exposures as significantly lower.

"That (number) seems too high to us to begin with, and that is a gross number," he said on Monday on a conference call.

Morgan Stanley evaluated mortgage exposure in collateralized debt obligations (CDOs) insured by the bond insurance arms of Ambac Financial Group Inc (ABK.N), FGIC, Security Capital Assurance SCA.N, and MBIA Inc (MBI.N), and determined that exposures by U.S. banks is likely in the $20 billion to $25 billion range.

Once the capacity of the bond insurers to pay out claims is taken into account, and assuming that a bankruptcy does not force the insurance arms of the companies out of business, likely losses by banks are in the $5 billion to $7 billion range, Peters said.

Bond insurers typically have holding companies, which issue stock and debt, while the insurance arm generates the income.

While the inability of an insurer to generate new business could weigh on the holding company and potentially drive the stock price down to zero, the insurance arms could continue to operate on their existing business and pay claims, Peters said.

In this scenario, the counterparty exposure of banks to the insurers is negligible, he added.

BAILOUT

Peters views a rating downgrade of MBIA or Ambac as likely and argues that supporting ailing insurers is not in the economic interests of banks.

"We just don't think the incentives exist, banks are clearly capital constrained, the exposure to the monolines is far from uniform, so one dealer might not want to help out their competitor when they have a very limited exposure," Peters said.

Hedge fund Long Term Capital Management (LTCM) was bailed out by a consortium of banks in 1998 after it faced margin calls on heavily levered exposures to U.S. government bonds and emerging market debt, creating some systemic risk in the view of U.S. regulators.

A consortium of banks is also looking at ways to boost the capital of bond insurers, raising hopes of a similar bailout, though Ambac is the main focus of the plan.
