What the company or idea is
Greensill Capital was a UK- and Australia-based financial services firm founded in 2011 that specialised in supply chain financing.
How it actually makes money
Greensill Capital made money by issuing notes backed by supply chain financing — primarily ‘future accounts receivables finance’ — which Credit Suisse–managed funds purchased to fund Greensill’s lending.
What works
Supply chain financing works when it is secured against verified, existing invoices. Greensill’s core product was not that. Its only working mechanism was investor appetite for yield — not credit quality.
What does not
Future accounts receivables finance does not work as stable collateral. It relies on uncertain future sales. When GFG Alliance defaulted on $5 billion of exposure, Greensill had no real assets to fall back on.
What to take from it
A business built on insurable risk cannot survive the lapse of insurance — especially when its entire funding model depends on third-party funds buying unsecured, forward-looking debt.
Is it worth your time
Yes. It reveals how opaque, unsecured credit structures can scale across banks, funds and corporates without market discipline — until they fail catastrophically.
