Banks face "systemic margin call," $325 billion hit: JPM

By Walden Siew

NEW YORK (Reuters) - Wall Street banks are facing a "systemic margin call" that may deplete banks of $325 billion of capital due to deteriorating subprime U.S. mortgages, JPMorgan Chase & Co (JPM.N: Quote, Profile, Research), said in a report late on Friday.

JPMorgan, which sent a default notice to Thornburg Mortgage Inc. (TMA.N: Quote, Profile, Research) after the lender missed a $28 million margin call, said more default notices and margin calls were likely. The Carlyle Group's mortgage fund also failed to meet $37 million in margin calls this week.
