Sainsbury’s has surrendered its UK banking licence and rebranded its financial services business as Sainsbury’s Money. Rather than operating as an independent retail bank, the supermarket has transitioned to a partner-led model under which Sainsbury’s core banking assets have been acquired by NatWest. The move reflects a broader shift in the UK banking industry, where affinity brands are focusing on partnerships with incumbents rather than operating as a bank.
Sainsbury’s originally received its full banking licence in 1997, becoming the first major British supermarket chain to operate its own bank. It initially launched as a joint venture with Bank of Scotland, before completing the buyout of the operations from Lloyds Banking Group (which had acquired Bank of Scotland) for £248m ($334.9m) in 2014.
Yet over time, stricter regulation, rising capital requirements, and increasing competitive pressure led Sainsbury’s to conclude that it could no longer compete effectively with the UK’s largest banks. The company therefore announced its gradual withdrawal from banking in January 2024, selling its credit card, loan, and savings portfolios to NatWest. The legal ownership of existing customer accounts transferred to NatWest in May 2025.

Sainsbury’s officially completed its new structural transformation on 1 July, 2026. Under the Sainsbury’s Money brand, new Nectar credit cards, savings accounts, and personal loans are now distributed under the Sainsbury’s brand, with NatWest providing the underlying banking infrastructure and product management. This enables Sainsbury’s to retain its brand presence and customer relationships without assuming the operational and regulatory responsibilities of running a bank.
Tesco & Barclays; M&S & HSBC
Similar partnerships between retailers and major banks have emerged in recent years, notably between M&S and HSBC as well as Tesco and Barclays. This highlights a broader market trend: rather than supermarkets disrupting incumbents, established banks are increasingly acquiring supermarket banking customers through strategic partnerships. These arrangements allow banks to scale their credit card and personal loan portfolios more efficiently while lowering customer acquisition costs.
At the same time, supermarkets increasingly recognise that their competitive advantage lies in their loyalty programs, customer relationships, and data rather than in managing complex banking infrastructure. As a result, non-financial brands are moving away from building banks from scratch and are instead forming partnerships in which retailers control the front-end customer experience and loyalty propositions, while established banks manage the back-end banking infrastructure—including regulatory compliance, capital requirements, and financial risk.
However, this trend may have winder implications for competition. As partnerships between established banks and major retailers become more common, challenger banks may find it more difficult to achieve scale and compete for customers. This could further strengthen the market position of incumbent banks, increasing their pricing power and potentially reducing competitive pressure to innovate in areas such as customer experience, rewards, and loyalty propositions.
