The Financial Conduct Authority (FCA) has warned consumers that loan notes and mini-bonds issued by unregulated companies are high-risk investments that can result in the loss of their entire investment. Promises of unusually high fixed returns, pressure to invest quickly, unclear risks and unsupported claims that products are asset-backed are key warning signs. The recent failure of litigation funder Woodville Consultants Ltd illustrates the potential losses. Although the FCA banned the marketing of speculative illiquid securities to ordinary retail investors from Jan. 1, 2021, unregulated firms may seek to use legal exemptions to promote them. Practices include encouraging consumers to self-certify as sophisticated or high-net-worth investors, using unregulated introducers that take substantial fees and implying legitimacy through overseas listings or links to FCA-authorized firms. Investors dealing with unauthorized firms are unlikely to have access to the Financial Ombudsman Service or the Financial Services Compensation Scheme. The FCA has issued more than 1,200 warnings so far in 2026 and urged consumers to verify firms through its Firm Checker.
