Credit Suisse, the Peter Greensill Family Trust and Citibank can all make claims on Greensill Capital as creditors gear up to fight over the assets of the collapsed financial group, which also threatens to bring down the global steel empire of billionaire Sanjeev Gupta because of the close links between the two.

The battle comes as Credit Suisse warned on Tuesday that it could take a financial hit as it tries to recover money for investors after liquidating supply chain finance funds holding invoices packaged by Greensill and recover $US90 million ($116 million) still owed on a loan.
