What really happened

Greensill Capital was a pioneer of “Supply Chain Financing” (SCF) — a method in which large corporations pay their suppliers faster against an interest premium that Greensill securitized as short-term receivables. SoftBank invested $1.5 billion in 2018 at a $7B valuation. David Cameron, former UK Prime Minister, was hired in 2018 as a lobbyist with stock options. Growth numbers looked excellent: in 2020 Greensill managed roughly $143 billion in SCF volume.

The risk concentration was dramatic. Greensill’s largest client was GFG Alliance, the steel empire of Indian-British Sanjeev Gupta. GFG owed Greensill $5 billion in receivables, which Greensill securitized as “asset-backed securities” — and which ultimately ended up in a Credit Suisse fund sold to Swiss private investors. The problem: GFG was structurally weak, and many of the “receivables” were based on projected future contracts — not on real, existing deliveries.

The end came suddenly. On March 1, 2021 insurer Tokio Marine canceled Greensill’s $4.6B insurance. Greensill’s entire business model rested on the receivables being insured — investors believed the risk was low because an A-rated insurance backed it. Without insurance the ABS model was dead. On March 4 Credit Suisse halted its $10B Greensill fund. On March 8 Greensill Capital UK filed for insolvency. BaFin closed the German Greensill Bank in Bremen — private depositors were protected up to €75,000 per account via deposit insurance. Larger holdings were lost.

The warning signs everyone ignored

The concentration on a single client (GFG, ~50% of the book) was a clear risk Greensill never disclosed publicly. SCF in general is an opaque business model — the valuation of receivables depends on whether the underlying contracts are real. The FT published multiple investigations from 2020 showing that many “receivables” were based on future, hypothetical supply-chain relationships — a form of “prospective receivables” that is legally borderline.

Political entanglements were suspicious. David Cameron actively lobbied the UK Treasury to include Greensill in COVID relief programs. Several text messages — later public — showed direct pressure on ministers. This type of political lobbying isn’t a direct balance-sheet indicator, but it points to a firm that prioritizes regulatory relief over market quality.

What investors can learn today

First: insured risks are only as good as the insurance. When the insurance is canceled, that’s not a reduction — it’s total loss of risk mitigation. Second: concentration risk in obscure asset classes is deadly. Greensill’s 50% concentration on GFG meant: GFG problems = Greensill insolvency. Third: “innovative financial products” are often just old risks in new wrappers. SCF is receivables securitization, which has existed since the 1980s. Greensill sold it as tech innovation — the risk content was unchanged.
