Axa said that it was exposed to about 300 million (£238 million) of Lehman debt while the German financial regulator Bafin declared its banks' exposure "managable".
It is far from clear what investors will get from the remains of Lehman. Under Chapter 11 the company is protected from its creditors while it attempts to run down its operations in a fairly orderly way.
Lehman said all of its broker-dealers would continue to operate and said customers could continue to trade or take other actions with respect to their accounts.
The bank is in talks over a sale of its asset management business, Neuberger Berman, and today said it was attempting a sale of its broker-dealer business. Neuberger is not part of the Chapter 11 filing and its portfolio management, research and operating functions remain intact, the bank said.
The US dollar plunged and safe-haven US Treasuries and gold prices jumped as investors fretted yet again about the state of the global financial market.
The Bank of England said it was monitoring conditions in the money markets and would act to stabilise them if necessary. As the morning went on, speculation began to spread that the Fed may decide on an emergency interest rate cut to stabilise the markets.
Lehman said in today's bankruptcy court filing that as at 31 May it had total debts of $613 million and assets of $639 billion.
