8 Min Read (This March.4 story corrects paragraph three to make clear that GAM Holdings closure of the fund related to concerns about perceptions of supply chain finance rather than about asset valuations) LONDON (Reuters) - A funding crisis at Greensill Capital could spill over to some of its high-risk borrowers and lead to losses for insurers and banks that have done business with the UK-based supply chain finance firm if its clients default, according to several industry experts and a review of public filings. Greensill, backed by Softbank Group Corp’s Vision Fund, helps companies spread out the time they have to pay their bills. The loans, which typically have maturities of up to 90 days, are securitized and sold to investors, allowing Greensill to make new loans.
