Greensill Capital presented itself as a supply chain finance provider helping suppliers access early payment. In reality, it was financing speculative borrowers like Sanjeev Gupta's GFG Alliance using 'prospective receivables' — invoices for goods not yet delivered to customers who hadn't ordered them. When insurers refused to renew coverage in February 2021, the entire structure collapsed within weeks, wiping out $10 billion in investor funds and exposing a business model that had never worked as advertised.
Lex Greensill built his company on a simple, compelling story. Large corporations often take 60, 90, or even 120 days to pay their suppliers. Small suppliers need cash flow to operate. Supply chain finance bridges that gap: a financier pays the supplier immediately, taking a small fee, then collects the full invoice amount from the large corporate buyer when the payment comes due. Greensill Capital claimed to have digitized and democratized this centuries-old practice, using technology to reduce costs and expand access to businesses that traditional banks ignored.
By 2019, Greensill reported arranging $143 billion in supply chain finance annually across 350 customers in 175 countries. The pitch resonated with major investors. SoftBank's Vision Fund invested $1.5 billion that year, valuing the company at approximately $7 billion. GAM Holding operated supply chain finance funds with $842 million invested in Greensill-arranged loans. Credit Suisse managed approximately $10 billion in Greensill-linked investment funds marketed to institutional investors and wealthy individuals as low-risk, short-duration investments backed by trade receivables from creditworthy corporations.
The structure appeared conservative. Loans were backed by specific invoices from named corporate buyers with strong credit ratings. Insurance policies from Bond & Credit Company and Tokio Marine protected investors against default. Independent auditors reviewed the loan portfolios. Regulatory filings classified the assets as trade receivables — a low-risk category under banking capital rules. Every layer of the structure communicated safety.
The problem was that the underlying collateral — the invoices securing the loans — often did not represent completed transactions. Greensill was financing borrowers using "prospective receivables," invoices for goods not yet manufactured, delivered to customers who had not placed orders, at prices not yet negotiated. This was not supply chain finance. It was asset-based lending using projected future cash flows as collateral, a fundamentally different risk profile.
At the center of Greensill's business was Sanjeev Gupta's GFG Alliance, a multinational commodities and manufacturing conglomerate that had acquired distressed steel mills, aluminum smelters, and energy operations across Europe, Australia, and the United States. By 2019, GFG owed Greensill approximately $5 billion — nearly half of Greensill's total loan book by some estimates, though the exact proportion remains disputed due to complex entity structures.
Grant Thornton, the administrators appointed when Greensill collapsed, documented in their June 2021 report that £3.5 billion of the £10 billion owed to creditors represented loans to GFG entities. These loans were secured against prospective receivables: invoices for steel GFG intended to produce and sell at some future date, to customers who had not committed to purchase orders, at commodity prices that fluctuated daily.
"The financing provided to GFG Alliance entities was not based on invoices for goods already delivered to creditworthy buyers. It was based on anticipated future production and sales that might not occur, secured against assets of uncertain value."
Grant Thornton Administrators — First Report to Creditors, June 2021The structure violated the fundamental principle of supply chain finance: that the financed invoice represents a completed transaction with a creditworthy buyer obligated to pay. GFG's invoices represented projections. If commodity prices fell, if production targets were not met, if anticipated customers declined to purchase, the receivables underlying billions in loans would not materialize. Greensill was not financing working capital within a stable supply chain. It was financing business expansion by a highly leveraged commodities trader.
The concentration created fragility. When credit insurers began examining Greensill's loan book in early 2021, the GFG exposure dominated their risk assessment. Losing that single relationship would eliminate half of Greensill's revenue. More critically, it would reveal that the company's claimed diversification across 350 customers was an accounting fiction. The business model was predicated on a single, speculative borrower.
Credit insurance was the keystone of the structure. GAM's and Credit Suisse's investment funds required that loans be insured against borrower default. The insurance policies allowed fund managers to classify Greensill-arranged loans as low-risk assets appropriate for conservative investment mandates. Bond & Credit Company and Tokio Marine, the two primary insurers, collected premiums for covering billions in exposure.
In January 2021, Bond & Credit began a detailed review of its Greensill policies, focusing on the GFG Alliance exposure. What the insurers found contradicted Greensill's marketing materials. The collateral was not invoices for completed deliveries. The insurers concluded they were covering speculative loans to a highly leveraged commodity trader, not conventional trade receivables.
On February 22, 2021, Bond & Credit informed Greensill it would not renew coverage when existing policies expired on March 1. Tokio Marine made a similar decision four days later. Without insurance, Credit Suisse and GAM could no longer hold Greensill-arranged loans within their fund mandates. Without access to these funding sources, Greensill could not refinance maturing loans. The business model collapsed instantly.
Lex Greensill attempted emergency negotiations to restore coverage, offering higher premiums and additional collateral. The insurers declined. They had determined the underlying risk was not what had been presented when the policies were issued, and that continuing coverage would expose them to losses they had not agreed to underwrite.
Investors later questioned why the insurers had not detected the prospective receivables structure earlier. Bond & Credit and Tokio Marine argued they had relied on representations from Greensill and on due diligence by the asset managers investing in the loans. The prospective nature of the receivables had been obscured in documentation that referred generically to "invoice finance" and "supply chain financing" without detailing the stage at which transactions were being financed. When insurers conducted detailed collateral reviews in early 2021, the true structure became clear.
On March 1, 2021, Credit Suisse froze redemptions across all four of its supply chain finance funds, trapping approximately $10 billion in investor capital. The bank announced it was conducting an urgent review of the underlying assets. GAM made a similar announcement regarding its $842 million in Greensill-linked funds.
On March 3, 2021, German financial regulator BaFin raided Greensill Bank AG offices in Bremen. Investigators had received information that the bank could not produce documentation proving the existence of billions of euros in receivables that supposedly secured its loans. BaFin filed a criminal complaint and revoked Greensill Bank's license, appointing an administrator to wind down operations.
The raid uncovered systematic documentation failures. German prosecutors alleged that some invoices had been fabricated entirely, listing customers who had no relationship with the supposed suppliers and purchases that had never occurred. Other loans were secured against prospective receivables but recorded in regulatory filings as conventional trade finance, understating the bank's risk exposure and capital requirements.
On March 8, 2021, Greensill Capital UK Ltd filed for insolvency, with Grant Thornton UK appointed as administrators. Greensill entities in Australia, the United States, and other jurisdictions followed with insolvency or administration proceedings in subsequent weeks. The global group, valued at $7 billion 18 months earlier, ceased operations.
For investors, the collapse triggered immediate consequences. Credit Suisse initiated liquidation of the underlying loan collateral, a process that revealed the concentration risk and credit quality problems that had been obscured while Greensill was operating. GAM's investors faced losses exceeding 70% as administrators determined that recovering value from GFG Alliance and other defaulted borrowers would take years and produce minimal returns. German retail depositors with balances exceeding €100,000 — the deposit insurance limit — faced losses estimated at 50-70% as Greensill Bank's liquidation proceeded.
As Greensill's collapse dominated financial news, attention turned to David Cameron, the former UK Prime Minister who had served as a paid advisor to Greensill from 2018 to 2021. Cameron had earned more than £7 million through salary and share options, compensation that evaporated when the company failed. But more damaging than the financial loss was the revelation of Cameron's lobbying activities during the COVID-19 pandemic.
In March and April 2020, as the UK government created emergency lending programs to support businesses through pandemic lockdowns, Cameron sent text messages directly to Chancellor Rishi Sunak requesting that Greensill be included in the COVID Corporate Financing Facility (CCFF). The texts, later disclosed to parliamentary investigators, showed Cameron leveraging his personal relationship with Sunak — who had worked under Cameron when Sunak was a junior Treasury minister — to seek preferential treatment for a company in which Cameron held significant financial interests.
"I have spent most of the last few days on a new initiative to try and help Greensill... Any help in looking at these issues, particularly the first one, would be greatly appreciated."
David Cameron text message to Rishi Sunak — April 2020, disclosed in parliamentary inquiryTreasury officials initially rejected Greensill's application, determining that supply chain finance companies were not eligible under the CCFF criteria. Cameron continued lobbying, arranging meetings between Greensill executives and senior Treasury officials. Greensill was eventually approved for a different Bank of England facility — the Coronavirus Large Business Interruption Loan Scheme (CLBILS) — through which it accessed approximately £400 million in government-backed loans in May 2020. The facility's terms were changed in November 2020 to exclude supply chain finance companies, after which Greensill could not access further funds.
The subsequent Boardman Review, an independent inquiry commissioned by the UK government, found that Cameron had broken no formal lobbying rules but demonstrated "a significant lack of judgment." The inquiry noted that Cameron had not registered as a lobbyist, had used informal personal channels rather than formal government processes, and had not disclosed to Treasury officials the full extent of his financial interest in Greensill's success.
The scandal extended beyond Cameron's individual actions. The Boardman Review documented that Lex Greensill had served from 2012 to 2015 as an unpaid "Crown Representative" advising Cameron's government on supply chain finance — while simultaneously building commercial relationships with government departments that became Greensill Capital clients. Greensill had an office inside 10 Downing Street and business cards identifying him as a government advisor. After leaving government in 2015, he immediately leveraged those relationships to win contracts with NHS supply chain operations and other public sector entities.
The inquiry led to reforms in UK lobbying transparency requirements, including new rules requiring former ministers to wait longer before taking paid advisory roles with companies that had business with government, and requiring disclosure when former officials lobby their successors.
Grant Thornton's investigation, documented in a series of reports to creditors from June 2021 onward, revealed the gap between Greensill's marketing and its actual operations. The company had presented itself as a diversified supply chain finance provider serving hundreds of corporate clients. The administrators found that approximately 70% of the loan book by value was concentrated in fewer than 10 borrowers, with GFG Alliance representing the largest single exposure.
The administrators pursued recovery actions against GFG Alliance and other borrowers, seeking repayment of outstanding loans. These efforts faced immediate obstacles. GFG's operations had been largely dependent on Greensill financing; without access to working capital, multiple GFG entities entered insolvency or administration proceedings. Attempting to liquidate collateral revealed that the steel mills, aluminum smelters, and commodity inventories pledged as security were worth substantially less than Greensill's loan values, particularly in forced-sale scenarios.
As of 2024, Grant Thornton has recovered approximately £2.5 billion of the £10 billion owed to creditors — a recovery rate near 25%. The administrators have stated that full recovery is unlikely and that final distributions may not occur until 2026 or later due to ongoing litigation against GFG and other parties.
German prosecutors filed charges against former Greensill Bank AG executives in 2022, alleging fraud, forgery, and breach of fiduciary duty. The charges focused on claims that executives knowingly recorded prospective receivables as completed trade finance in regulatory filings, understating the bank's risk exposure, and that some invoices securing loans had been fabricated. The criminal proceedings are ongoing as of 2024, with trial dates not yet set.
In May 2021, the UK Serious Fraud Office opened a criminal investigation into suspected fraud and money laundering at GFG Alliance. The investigation focuses on whether GFG executives made fraudulent misrepresentations to Greensill about the nature and value of assets securing loans, and whether borrowed funds were diverted to purposes other than disclosed. The SFO has executed search warrants, seized documents and electronic devices, and interviewed witnesses, but as of 2024 has not filed charges.
Sanjeev Gupta has denied wrongdoing, stating publicly that he was a victim of Greensill's misrepresentations about the availability and terms of financing. Gupta has argued that GFG provided accurate information to Greensill about its operations and that financing structures were designed by Greensill, not GFG. Multiple GFG entities have entered administration or restructuring since 2021, complicating investigators' ability to trace fund flows and establish timelines of knowledge.
Legal experts note that fraud prosecutions in complex corporate lending cases face inherent difficulties. Prosecutors must prove defendants knowingly made false statements, not merely optimistic projections that failed to materialize. Documentation showing executive knowledge that receivables were prospective rather than completed, or that invoices were fabricated, is required for conviction — a high evidentiary bar when transactions involved hundreds of entities across multiple jurisdictions with differing accounting standards.
Investor lawsuits following Greensill's collapse have focused on who knew about the prospective receivables structure and when they knew it. Credit Suisse, GAM, and SoftBank all conducted due diligence before investing billions. Why did none of them detect that the underlying collateral was not conventional supply chain finance?
Credit Suisse has argued in legal filings that Greensill provided misleading representations in fund documentation, describing loans as backed by "invoices" and "receivables" without disclosing their prospective nature. The bank claims it relied on insurance coverage from Bond & Credit and Tokio Marine as additional validation that the assets met industry standards for supply chain finance. When Credit Suisse conducted detailed reviews in March 2021, it discovered the prospective receivables structure and immediately froze the funds.
GAM has made similar arguments, pointing to reliance on credit insurer due diligence and on Greensill's representations. Internal GAM emails disclosed during litigation show fund managers discussed GFG's creditworthiness and concentration risk, but not the prospective nature of the receivables until after the collapse. GAM's board-commissioned review found the funds had exceeded internal limits on single-obligor exposure, suggesting risk management failures independent of whether prospective receivables were disclosed.
SoftBank wrote down its entire $1.5 billion investment to zero in fiscal 2020-21. Masayoshi Son, SoftBank's founder, acknowledged in investor presentations that Vision Fund's due diligence had not adequately assessed Greensill's credit concentration and collateral quality. Internal SoftBank communications reviewed during litigation suggested concerns had been raised about Greensill's risk profile before the collapse, but investment committee members believed the supply chain finance model and insurance coverage reduced risk compared to direct lending.
The prospective receivables structure was not entirely hidden. Greensill Capital's own marketing materials, reviewed after the collapse, contained references to financing "future receivables" and helping clients "unlock the value of anticipated sales." But these references appeared alongside language describing "invoice financing" and "working capital optimization" that suggested conventional supply chain finance. Whether this constituted fraudulent misrepresentation or aggressive marketing of an unconventional structure remains contested in ongoing litigation.
Greensill's collapse occurred during a period of regulatory attention to "shadow banking" — financial intermediation occurring outside traditional banking supervision. Greensill Capital was not a bank in most jurisdictions where it operated. Its German subsidiary, Greensill Bank AG, operated under BaFin supervision, but the global group's primary operations were structured as asset management and advisory services, falling outside bank regulatory frameworks.
This regulatory gap allowed Greensill to arrange billions in loans using structures that banks would not have been permitted to employ. Banks face concentration limits preventing excessive exposure to single borrowers. Banks must hold capital against risky assets based on detailed regulatory classifications. Banks undergo regular examinations by supervisors with authority to access detailed loan files and collateral documentation. Greensill operated without most of these constraints until German regulators intervened in March 2021.
The case demonstrates the risks when financial innovation—in this case, claimed technology-enabled efficiency in supply chain finance—is accompanied by regulatory arbitrage that places activities outside established supervisory frameworks. It is unclear whether existing regulations would have prevented Greensill's structure if the company had operated as a bank, or whether the fundamental business model of financing speculative borrowers with prospective receivables could have been concealed within any regulatory framework.
Greensill also illustrates the challenge of distinguishing between fraud and aggressive business practices that fail. Lex Greensill has maintained in court filings that he believed GFG Alliance would repay its loans, that he believed commodity prices would support the projected revenues underlying prospective receivables, and that he believed credit insurers understood the structures they were covering. Whether these beliefs were reasonable given information available at the time, or whether they constituted reckless disregard for risk that crossed into fraudulent misrepresentation, remains the central question in ongoing legal proceedings.
For investors who lost billions, these distinctions matter legally but provide little practical comfort. The money is gone, recovered only partially through years of administrator-led liquidation proceedings. The lesson is structural: when investment products marketed as low-risk produce steady returns above comparable safe assets, the source of that excess return warrants scrutiny. Greensill's investors received fees suggesting trade receivables financing but backed by speculative lending risk. When that risk materialized, the safety mechanisms—insurance, diversification, credit quality—proved illusory.
