    Root Causes

    Greensill Capital was a supply chain finance company founded by Australian financier Lex Greensill. The business model involved providing short-term financing to companies by purchasing their receivables at a discount — essentially paying suppliers early and collecting from buyers later. At its peak, Greensill facilitated over $143 billion in financing and was valued at $7 billion after a $1.5 billion investment from SoftBank's Vision Fund. The company collapsed spectacularly in March 2021 when its key insurer, Tokio Marine subsidiary BCC, refused to renew credit insurance policies covering $4.6 billion in Greensill-arranged financing. Without insurance, the bonds Greensill packaged and sold through Credit Suisse's supply chain finance funds became unmarketable. Credit Suisse froze $10 billion in funds, and Greensill filed for insolvency within days. Investigations revealed alarming concentration risk: a huge portion of Greensill's lending went to companies linked to steel magnate Sanjeev Gupta's GFG Alliance, much of it based on 'prospective receivables' — invoices for goods and services that hadn't been delivered yet, and in some cases, might never be. Greensill had also engaged former British Prime Minister David Cameron as a senior adviser, who lobbied the UK government for Greensill to access emergency COVID lending programs. The scandal led to a formal UK government inquiry, the collapse of Credit Suisse's supply chain finance business (contributing to CS's eventual takeover by UBS), and criminal investigations in Germany. Lex Greensill's companies in the UK and Australia entered administration, leaving thousands of workers at GFG Alliance steel plants facing uncertain futures.

    Causal Chain

    Derived · heuristic

    This is our reading of the causal chain — separated from the verifiable facts above. Timeline dates, funding numbers and filings are facts (see methodology); root / proximate / terminal attribution is judgement based on public evidence.

    Root cause

    Structural mismatch between burn rate and revenue growth: capital was consumed on scaling before unit economics turned positive, leaving no bridge when the next round failed to close.

    Contributing factors
    • Extreme concentration risk — massive exposure to GFG Alliance / Sanjeev Gupta
    • Lending based on 'prospective receivables' (invoices for future or fictional transactions)
    • Dependency on a single insurer (BCC/Tokio Marine) for entire business model
    • Political lobbying (David Cameron) created false legitimacy
    • Competitor "Taulia (SAP)" captured the same market: Diversified client base, technology-driven, embedded in SAP ecosystem

    Key Lessons Learned

    1. Concentration risk is existential risk

    When a finance company's portfolio is dominated by a single borrower or group, the failure of that borrower means the failure of the company. Diversification isn't optional — it's survival.

    2. Fictitious receivables are fraud

    Lending against 'prospective receivables' — invoices for goods not yet delivered — is not innovation. It's creating fake collateral, and it inevitably unravels.

    3. Single-dependency business models are fragile

    Greensill's entire model depended on one insurer's willingness to provide coverage. When that single point of failure broke, everything collapsed in days.
