Greensill Capital collapsed in March 2021 after trade credit insurers declined to renew coverage on its loan portfolio, which was heavily concentrated in loans to Sanjeev Gupta’s GFG Alliance. Without insurance, Credit Suisse froze $10 billion in funds. The underlying cause was Greensill financing “future receivables” — revenue that didn’t yet exist — and packaging those loans as low-risk investment products.
The Greensill Capital collapse is one of the most dramatic financial failures of the past decade. In March 2021, Greensill Capital filed for insolvency, triggering the freeze of $10 billion in Credit Suisse funds and sending shockwaves through steel plants, pension portfolios, and boardrooms across three continents.
The core problem was straightforward: a lender built on trust and creative accounting, a client empire hungry for cash, and a bank that stopped asking hard questions.
The story did not end in 2021. As of 2025, Gupta’s GFG Alliance still owes roughly $900 million to creditors tied to those frozen funds. Investors who got locked out of their money have recovered approximately 90 cents on the dollar through UBS-managed settlements — but many are still fighting. And the steelworkers whose jobs depended on Gupta’s expansion are still living with the consequences.
If you want to understand how this happened, who caused it, and what it still means today, this is where to start.

The Three Players You Need to Know
Sanjeev Gupta ran GFG Alliance, a global collection of steel and commodities businesses. He built a reputation as an industrial rescuer — buying failing steel plants across the UK, Europe, and Australia and promising to revive them. He needed a constant flow of cheap financing to keep growing.
Lex Greensill built Greensill Capital around supply-chain finance. His firm acted as a middleman between companies and investors, essentially fronting cash to suppliers waiting to get paid. The problem: Greensill was increasingly financing invoices tied to revenues that did not yet exist — and in some cases, may never have existed. Lex Greensill lost his billionaire status after the collapse and has not returned to prominence in finance.
Credit Suisse was the 160-year-old Swiss bank that packaged Greensill’s loans into investment funds and sold them to wealthy clients as low-risk, cash-like products. In a near-zero interest rate environment, the funds looked attractive. Credit Suisse was collecting fees, Greensill was expanding, and Gupta was borrowing. For a few years, everyone appeared to win.
What Supply-Chain Finance Actually Is — And How Greensill Bent the Rules
Most articles skip this part. They assume you already know what “invoice financing” or “receivables” mean. You probably don’t, and that’s fine.
Say you run a factory that supplies steel to a car manufacturer. The car company owes you $1 million, but won’t pay for 90 days. Your factory has bills due next week. A firm like Greensill Capital steps in, pays you most of that $1 million now, and then waits to collect the full amount from the car company later. They make their money on the difference.
Legitimate supply-chain finance works well when:
- The invoices are real and already issued
- The buyers are creditworthy
- The lender stays disciplined about what it funds
Greensill bent all three of those rules. They began financing “future receivables” — money that companies might earn from clients they hadn’t yet sold anything to. In some cases, they were financing relationships with clients that barely existed. This is sometimes called “prospective” or “anticipated” receivables financing, and it sits in a legal grey area that auditors and regulators were slow to examine closely.
The critical problem: the Credit Suisse funds were marketed to clients as holding short-term, self-liquidating trade receivables — predictable, low-risk paper. What they actually held was increasingly speculative. The label said one thing. The contents said another.
The Political Connection That Added Credibility
David Cameron, the former UK Prime Minister, became an adviser to Greensill Capital after leaving office in 2016. His presence gave the firm a layer of credibility it had not earned through its fundamentals.
A UK parliamentary inquiry later confirmed that Cameron sent text messages directly to the Chancellor of the Exchequer, asking for Greensill to be included in the COVID-19 Coronavirus Large Business Interruption Loan Scheme. That effort failed after civil servants pushed back. Cameron subsequently apologised — not for the lobbying itself, but for how he conducted it.
The broader issue this exposed: in the UK, there was no formal code of conduct restricting what former ministers could do on behalf of private clients, or how they could approach current ministers. That gap has since been debated but not comprehensively closed.
For Greensill and Gupta, reputation was a product. As long as prominent names were attached and the returns looked steady, fewer people asked how the money was actually moving.
The First Cracks: Why the Insurance Collapse Mattered
In financial blow-ups, warning signs typically show up in the insurance first — and Greensill was no exception.
Greensill’s model depended on trade credit insurance — coverage that protected investors if Gupta’s companies failed to repay. In late 2020, Tokio Marine, one of its major insurers, declined to renew that coverage. When professional risk assessors walk away from a book of business, it usually means what they see privately doesn’t match the story being told publicly.
Rather than slow down, Greensill reportedly leaned on a captive insurer — an internal entity they effectively controlled — to fill the gap. Writing your own insurance is not really insurance. It’s a way to make a spreadsheet look safer than it is, without transferring any actual risk to an independent party.
Without real external insurance, the entire value proposition of the Credit Suisse funds was compromised. Investors thought they held insured, short-term debt. They held uninsured, concentrated exposure to one client group.
The Greensill Capital Collapse: What Broke and Why
By March 2021, Greensill Capital had run out of options. The firm filed for insolvency in Australia and the UK. Credit Suisse froze the Supply Chain Finance Funds almost immediately.
The assets inside those funds were not the diversified, stable products Credit Suisse had described to clients. They were heavily concentrated in loans to Gupta’s companies — a problem known in finance as single-name concentration. When the Gupta connection fell apart, there was nothing else to hold the funds up.
Credit Suisse’s own internal risk controls had failed to flag this concentration adequately. A subsequent review commissioned by Credit Suisse’s board found that fund management and risk oversight had significant shortcomings. The Swiss regulator FINMA later formally criticised Credit Suisse’s handling of the funds and opened enforcement proceedings.
Investors — many of them retirees, family offices, and smaller institutions who believed they were holding something close to cash — found their money locked away. Some waited years to see partial recovery.
Regulatory Fallout: What Authorities Actually Did
This part often gets skipped. It shouldn’t.
In the UK:
- The Serious Fraud Office opened a criminal investigation into GFG Alliance’s financing arrangements in May 2021. That investigation remains open as of 2025.
- The Financial Conduct Authority reviewed how Credit Suisse’s UK operations marketed the funds to retail and semi-professional investors.
- Wyelands Bank — a UK lender connected to Gupta’s network — was shut down by the Prudential Regulation Authority in June 2021 after regulators found it had lent excessively to GFG Alliance entities, in breach of concentration limits.
In Switzerland:
- FINMA found that Credit Suisse had violated supervisory law in its management of the supply chain finance funds. The regulator required remedial action and published its findings publicly — an unusually direct move for a Swiss authority.
In Australia:
- ASIC, the Australian securities regulator, examined Greensill Capital Australia’s operations. Australian insolvency proceedings ran in parallel with the UK process.
Industry-wide:
- The collapse triggered renewed discussion among regulators in Europe and the UK about disclosure standards for supply-chain finance products — specifically,y whether “future receivables” financing should be treated differently from traditional invoice discounting. Formal rule changes have been slow.
The Real-World Impact Beyond the Boardroom
The Greensill Capital collapse was not just a story about billionaires and bankers. Real people absorbed the damage.
Steelworkers at GFG Alliance plants across the UK and Australia spent months not knowing whether their plants would close. Several facilities were put up for sale or entered into restructuring. Communities that had already been through one round of industrial decline faced another. In Liberty Steel UK — GFG’s British arm — thousands of jobs were at risk for an extended period.
Investors who had trusted Credit Suisse’s marketing of these funds as safe, liquid products discovered that “safe” had been a sales pitch, not a guarantee. The recovery process, managed first by Credit Suisse and later by UBS after its 2023 takeover, dragged on for years. By 2024, UBS had reached settlements with most investors, with reported recoveries of approximately 90 cents on the dollar — though actual rates varied by fund tranche and investor class.
As of 2025, approximately $900 million in claims against GFG Alliance entities remain unresolved. That gap — 10 cents on every dollar across a $10 billion fund — represents real losses for real people, not rounding errors on an annual report.
Three Things This Collapse Actually Teaches You
These lessons are specific to what happened here — not recycled advice from every financial scandal.
Complexity is not the same as safety. The Credit Suisse funds were sold as boring, cash-like products. The underlying assets were anything but. The specific mechanism — “future receivables” financing — was obscure enough that most investors and even some fund managers didn’t scrutinise it. When you can’t explain in one sentence how an investment actually makes money and who takes the risk if it doesn’t, that gap in understanding typically benefits the seller.
Check who gets paid when you borrow more. Greensill earned fees tied to the volume of Gupta’s borrowing. Credit Suisse earned fees from selling the funds. Nobody in that chain had a financial reason to slow down or ask whether the loans were sound. The structure rewarded growth, not quality. Before you trust a financial product, ask: Does my adviser make more money if I borrow more, or only if I do well?
Regulatory approval is not endorsement. These funds were registered, reviewed, and sold through a major regulated bank. Regulators approved the structure. None of that prevented the losses. Regulatory compliance sets a floor — it doesn’t guarantee that what you’re buying is what you think it is. That distinction is yours to investigate.
Frequently Asked Questions
What exactly was the connection between Sanjeev Gupta, Greensill Capital, and Credit Suisse?
Gupta’s GFG Alliance was Greensill’s largest client, using supply-chain finance to fund an aggressive global expansion. Greensill packaged those loans into investment funds. Credit Suisse sold those funds to wealthy clients as low-risk products. When Gupta’s companies couldn’t sustain their debt load, the entire chain broke.
Why did Greensill Capital suddenly collapse in 2021?
The collapse accelerated when trade credit insurers declined to renew coverage in late 2020, removing the safety net that made the funds appear secure. Without insurance, investors and regulators lost confidence. Greensill filed for insolvency in March 2021, triggering the fund freeze.
How much money did Credit Suisse clients actually lose?
Credit Suisse froze approximately $10 billion in funds. Through UBS-managed settlements completed in 2024, most investors recovered around 90 cents on the dollar — though recovery rates varied by fund tranche. Roughly $900 million in claims against GFG Alliance entities remained outstanding as of 2025.
What happened to Lex Greensill after the collapse?
Lex Greensill lost his billionaire status and has not returned to a prominent role in finance. He has not faced criminal charges as of 2025, though investigations in multiple jurisdictions have examined Greensill Capital’s practices.
What is the current status of the SFO investigation into GFG Alliance?
The UK Serious Fraud Office opened its investigation into GFG Alliance’s financing arrangements in May 2021. As of 2025, the investigation is ongoing. No charges have been publicly confirmed.
What happened to David Cameron as a result of his involvement?
Cameron was not charged with any offence. He apologised to a parliamentary committee for the manner in which he lobbied ministers on Greensill’s behalf. His involvement accelerated a broader debate about the revolving door between government and private finance, though comprehensive reforms have not followed.
