The financial world was rocked once again as Lex Greensill, the financier behind the fallen Greensill Capital, made his first courtroom appearance since his company’s dramatic collapse in 2021. In a high-profile case currently being heard in London’s High Court, Greensill disclosed internal tensions at SoftBank, claiming that some senior executives felt “threatened” by his close relationship with the firm’s billionaire founder, Masayoshi Son. This revelation came as part of a $440 million lawsuit filed by a former Credit Suisse fund against SoftBank over a failed investment arrangement involving U.S. construction firm Katerra. The case could have wider implications for some of the world’s most powerful financial institutions.
I. A Clash Inside SoftBank
1. Greensill’s Relationship with Masayoshi Son
Lex Greensill described his frequent trips to Tokyo where he regularly met with Masayoshi Son, the influential founder of SoftBank. These sessions, which Greensill characterized as mentoring meetings, often involved private dinners. He referred to Son respectfully as “Son-san,” reflecting a bond that extended beyond business formality.
However, Greensill revealed that this close relationship did not sit well with everyone at SoftBank. According to his testimony, certain high-ranking members of the organization viewed his proximity to Son as a threat and began undermining his efforts. This discord allegedly complicated internal dealings, ultimately exacerbating issues that contributed to Greensill Capital’s downfall.
2. Power Struggles and Legal Consequences
The trial currently unfolding is centered on allegations that SoftBank worked alongside Greensill in late 2020 to restructure Katerra—a U.S.-based construction company in which both had vested interests. Credit Suisse, now under UBS after a 2023 emergency acquisition, claims that this restructuring was engineered to benefit SoftBank at the expense of Credit Suisse’s clients. These clients had invested in funds tied to Greensill Capital, which were supposed to be secure but turned out to be highly vulnerable.
SoftBank has firmly denied the accusations, labeling the lawsuit as opportunistic. Its legal team described it as “a classic example” of plaintiffs targeting wealthy firms to cover their own financial missteps.
II. The Rise and Fall of Greensill Capital
1. From Humble Beginnings to Global Finance
Lex Greensill’s story is one of dramatic ascent and equally dramatic decline. Originally a melon farmer from Australia, Greensill launched his financial firm in 2011 with a focus on supply chain finance. His model involved providing upfront payments to companies based on their outstanding invoices in exchange for a fee.
His innovative yet complex approach to financing quickly gained traction, allowing him to attract high-profile investors and powerful political allies. Among those drawn into his orbit were former UK Prime Minister David Cameron and ex-Australian Foreign Minister Julie Bishop, both of whom took advisory roles.
2. Political Ties and Controversial Deals
Greensill Capital’s deep entanglement with government figures became a focal point following its collapse. It was revealed that David Cameron had directly lobbied UK government officials, attempting to secure access to taxpayer-backed Covid loan schemes for the company. This triggered a major lobbying scandal that dominated British headlines for months.
Despite its political connections and ambitious plans—including a proposed £22 billion IPO—Greensill Capital began to unravel when key insurance backers declined to renew coverage for billions in loans. These loans were essential to maintaining its financial structure. The collapse was swift and devastating, leading to significant losses for investors, including Credit Suisse clients.
3. Credit Suisse and the Domino Effect
The most immediate financial fallout came for Credit Suisse, which had bundled Greensill’s loans into funds marketed to wealthy individuals and institutions. When Greensill collapsed, Credit Suisse was forced to suspend approximately $10 billion in these funds. Clients were left with massive losses, and confidence in the 167-year-old Swiss bank was severely damaged—a blow from which it never recovered.
Eventually, Credit Suisse itself collapsed in 2023, prompting a rushed government-brokered takeover by UBS. Now, UBS is leading efforts to recoup funds and salvage what remains for affected investors. The ongoing lawsuit is a key part of that strategy.
III. SoftBank’s Investment Gambles
1. The Vision of Masayoshi Son
Masayoshi Son has built a reputation as one of the boldest investors in the tech world. His firm, SoftBank, has backed major companies like Alibaba, ByteDance (the parent company of TikTok), and UK chip designer Arm. With personal wealth estimated at $29 billion, Son has been both admired and criticized for his aggressive investment style.
His creation of the Vision Fund, bolstered by support from Saudi Arabia, was designed to supercharge tech investments across the globe. During the height of the Covid-era tech boom, SoftBank’s holdings soared in value, reinforcing Son’s status as a tech visionary.
2. Setbacks and Recalibration
However, once the pandemic-fueled tech bubble began to deflate, SoftBank was forced into a phase of retrenchment. Several of its investments—Katerra included—failed to live up to expectations. While Son remains committed to backing innovative ventures, recent years have introduced a dose of caution to his typically high-risk strategy.
The fallout from Greensill’s collapse and the allegations surrounding Katerra have added to SoftBank’s growing list of challenges. The ongoing trial, set to run through July 4th, may yet uncover more details that reshape how such financial relationships are viewed moving forward.
Conclusion
Lex Greensill’s courtroom revelations have cast a spotlight on the internal dynamics at SoftBank, reigniting debates about corporate governance, high-stakes finance, and the blurred lines between political influence and private enterprise. While SoftBank continues to deny wrongdoing, the case highlights the complex web of interests and personalities that fueled the meteoric rise—and dramatic fall—of Greensill Capital. As the trial progresses, the world will be watching to see who ultimately bears the responsibility for one of the most high-profile financial collapses in recent memory.
