Monument Bank
Monument Bank Limited is a UK challenger bank headquartered at 33 Cavendish Square, London, purpose-built for the "mass affluent" - professionals, entrepreneurs, and savers with substantial assets who have historically been underserved between mainstream retail banking and private banking. It received a full UK banking licence in November 2021, launched its first app-based savings products in early 2022, and in 2024 joined Tech Nation's Future Fifty cohort of leading pre-IPO companies. Monument is authorised by the Prudential Regulation Authority (PRA) and regulated by the Financial Conduct Authority (FCA) and PRA under FRN 849724, with eligible deposits protected by the FSCS. It is privately held (investors include Dubai Investments, which took a ~9% stake) and operates the technology it spun out as Monument Technology. Its current product suite is app-only savings - easy access accounts, cash ISAs, limited access savers, notice accounts, and fixed-term deposits - plus a planned move into buy-to-let and property lending. As a smaller, savings-and-lending-focused ASPSP it is NOT one of the CMA9 mandated banks and does not publish a public developer portal; where it participates in UK Open Banking it does so against the Open Banking Implementation Entity (OBIE) Open Data and Read/Write API Standards under the PSD2 / FCA framework, secured with FAPI-grade OAuth2/OIDC, mutual-TLS, and PSD2 strong customer authentication.
Monument Bank publishes 34 APIs on the APIs.io network, including Account Access Consents API, Accounts API, ATM API, and 31 more. Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.
Monument Bank’s developer surface includes authentication, engineering blog, product news, support, FAQ, and 17 more developer resources.
