Greensill's UK Guarantee Lawsuit: A Structural Test for Government Risk Assumption

The lawsuit now before the UK courts is a direct test of the government's role in guaranteeing private sector lending during a crisis. Germany's defunct Greensill Bank AG is seeking about £330 million from the UK, accusing it of wrongly canceling Covid-era loan guarantees it had agreed to for loans made by Greensill Capital UK. The dispute centers on a specific program: the Coronavirus Large Business Interruption Loan Scheme (CLBILS, or CLBILS), which was introduced in April 2020 to protect firms from crashing into insolvency. Instead of the government lending directly, it accredited specific lenders like Greensill Capital UK to deliver finance, backing each loan with an 80% government guarantee.

The UK government terminated these guarantees in 2022, citing Greensill Capital UK's failure to comply with the program's rules. The core allegation is that Greensill Capital UK lent millions more than it should have to firms linked to steel tycoon Sanjeev Gupta, exceeding the scheme's £50 million cap on lending to a single company. The government's legal argument hinges on the principle of good faith. Its counsel stated that Greensill Capital UK did not "act in good faith" and did not exercise the level of care, control and diligence required by the guarantee agreement. This case is a structural test: it will set a precedent for whether governments can enforce compliance with the terms of these crisis lending programs, even when the guarantees have been a critical lifeline for accredited lenders.

The stakes are high, not just for the parties involved but for the future of state-backed lending. The UK's business loan support program was designed to be a temporary bridge, but its collapse has triggered a cascade of legal and regulatory scrutiny. The government's decision to terminate the guarantees followed an investigation that found GCUK providing over £50m to a single corporate group in direct breach of the CLBILS rules. Yet the termination was not based on a single violation. The British Business Bank, which administers the scheme, noted there were "a number of breaches" prompting the decision. This ambiguity-what specific breaches were deemed material-leaves a cloud over the program's integrity and raises questions for other accredited lenders about the standards they must meet.

Financial Mechanics and the Public Cost of Guarantee Abuse

The lawsuit now hinges on a precise financial calculation: what was the public exposure from lending that allegedly flouted the rules? The CLBILS scheme was structured as a classic government guarantee program, where the state took on the bulk of the credit risk. For each loan, the government provided an 80% guarantee on the value of the loan, meaning the taxpayer could be liable for up to that portion if a borrower defaulted. This mechanism was designed to de-risk lending and get capital flowing during the pandemic.

The core of the dispute is the scale of the non-compliant lending. The British Business Bank (BBB) investigation found that Greensill Capital UK advanced a total of £400m to borrowers under the CLBILS, with £350m going to seven companies within the GFG Alliance controlled by Sanjeev Gupta. This figure is critical because it represents the pool of loans that may have been improperly guaranteed. The scheme's rules explicitly capped lending to any single corporate group at £50 million. By lending £350 million to Gupta-linked firms, GCUK clearly breached this cap, a violation the BBB cited as a key reason for its recommendation.

The potential public cost, therefore, is quantified by the guarantee percentage applied to this non-compliant lending. The UK's liability is capped at 80% of the total £400 million in loans, which would be £320 million. However, the termination decision was not based solely on the £50 million cap breach. The BBB noted there were "a number of breaches" that prompted its recommendation. This broader finding suggests the public risk may extend beyond the simple calculation of 80% of £350 million. It implies deeper failures in GCUK's due diligence and compliance processes that could have exposed the government to even greater losses had the guarantees remained in place.

The timeline of the government's response is also telling. Guarantees were suspended in March 2021 following the investigation into GCUK's lending practices. The BBB then published its recommendation to terminate the guarantees in July 2022. The business secretary, Kwasi Kwarteng, accepted this recommendation in April 2023, formally ending the government's liability. This sequence-suspension, investigation, recommendation, and final termination-shows a deliberate, multi-stage process to contain risk. The termination decision, however, now becomes the focal point of legal challenge, with the government arguing it acted to protect public funds from a lender that failed to meet its obligations.

Broader Implications for Crisis Lending and Financial Stability

This lawsuit is not an isolated legal wrangle; it is a pivotal moment for the credibility of government guarantee programs and the accountability of the lenders they empower. The Greensill collapse, which saw the firm's network peak at a $7 billion valuation, has triggered a wave of investigations and litigation. The outcome of the UK guarantee case will directly shape how accredited lenders view the risk and enforceability of state backing in future economic downturns. If the government's termination is upheld, it will reinforce the principle that guarantees are conditional on strict compliance, not a blanket safety net. A ruling against the government, however, would undermine that principle and create a precedent where lenders could argue that guarantees are effectively irrevocable, potentially encouraging riskier behavior in future crisis programs.

The case also highlights deep-seated governance failures within the Greensill ecosystem. Separate German charges against Greensill Bank board members allege regulatory breaches during a 2019 refinancing, pointing to a pattern of opaque transactions and poor oversight. This context is crucial. The UK's termination decision was not based on a single violation but on a broader pattern of non-compliance, including the £350 million advanced to Gupta-linked companies in apparent contravention of the scheme's rules. The German administrator's pursuit of the UK, therefore, is part of a wider effort to recoup funds from any entity perceived to have facilitated or benefited from the collapse. This multi-jurisdictional scrutiny underscores the complexity of liability chains in interconnected financial networks.

The recent $440 million London lawsuit, where a judge ruled SoftBank acted in good faith, further illustrates this complexity. In that case, Judge Robert Miles dismissed the lawsuit, stating SoftBank "believed in good faith" that funds would be used to repay noteholders. This decision, while favorable to SoftBank, does not absolve the broader network of responsibility. It demonstrates how legal outcomes can vary based on specific facts and the burden of proof, creating a patchwork of accountability. For policymakers, the lesson is clear: future crisis lending programs must include not just clear rules, but also robust, independent monitoring and a mechanism for swift, transparent enforcement to prevent the kind of regulatory arbitrage and governance breakdown that characterized Greensill's rise and fall.

The bottom line is that this case is a structural test. It will determine whether state guarantees remain a credible tool for stabilizing markets during a crisis, or if they become a source of legal uncertainty that lenders may exploit. The UK's decision to terminate, based on a multi-faceted investigation, sets a high bar for compliance. For the credibility of the entire system to be preserved, that bar must be upheld.

Catalysts, Risks, and What to Watch

The immediate catalyst is the court hearing scheduled for Thursday. This is where the UK government's legal argument will be formally presented. The core of its case is that Greensill Capital UK did not "act in good faith" and failed to meet the required standards of care and diligence. The government will likely emphasize the BBB's finding of "a number of breaches" beyond the simple lending cap violation, framing the termination as a necessary enforcement action to protect public funds.

A key risk for the UK is that a ruling in favor of the German administrator could set a damaging precedent. The administrator's argument hinges on a technicality: that the Gupta-linked firms, known as the "Liberty Borrowers," were not legally part of the same corporate group under EU rules, thus not triggering the £50 million cap. A win for this position would severely weaken the enforceability of guarantee terms, suggesting that lenders could structure transactions to circumvent rules without facing termination. This would undermine the credibility of future crisis lending programs, which rely on clear, unambiguous rules.

Investors should monitor the case's progress as a leading indicator of the durability of government-backed lending. The outcome will signal whether states can reliably withdraw guarantees for non-compliance, or if such commitments become effectively irrevocable. The broader context of Greensill's collapse adds systemic weight. Ongoing investigations, including German prosecutors charging two board members over a 2019 refinancing, highlight a pattern of governance failure that the UK's termination decision sought to address. The case is a test of whether accountability can be enforced across borders in a financial network that once spanned billions in assets.

The bottom line is that this hearing is a structural stress test. The UK's position rests on a multi-stage investigation and a finding of multiple breaches. If upheld, it reinforces a principle of conditional state support. If overturned, it risks creating a legal gray area that could deter future government intervention in a crisis.
