ZURICH (Reuters) - Credit Suisse said on Monday that four supply chain finance funds linked to Greensill had around $880 million in cash as of last week after it had already distributed $4.8 billion to investors. Switzerland’s second-biggest bank is reeling from its exposure to the collapse first of Greensill Capital and then Archegos Capital Management within a month. Its asset management unit was forced last month to shut $10 billion of supply chain finance funds that invested in bonds issued by Greensill after the British firm lost credit insurance coverage shortly before filing for insolvency.
