Strong execution across lending, cards, service delivery and risk management has helped deepen the bank’s retail franchise in a competitive domestic market
E.SUN Bank’s retail banking story in Taiwan is strongest when viewed as an operating model rather than a single initiative. The bank has been building scale across lending and cards, but the more convincing part of the case lies in how that scale is being supported by faster processing, tighter risk control and more consistent service delivery.
Personal lending sits at the centre of that model. E.SUN has redesigned the business around an end-to-end digital process supported by a unified system covering investigation, underwriting, pricing, disbursement and review.
By October 2025, more than 98% of personal loan applications were submitted digitally. That figure matters because it signals a process that has moved well beyond the pilot stage and into routine retail banking.
The bank’s position in the market also gives the story weight. In the second quarter of 2025, E.SUN ranked among Taiwan’s top three in credit loan outstanding balance and market size. It ranked second in circulating credit cards, with 8.75 million cards, and third in annual card spending at NT$498.6bn ($15.7bn). Those are large retail numbers and they show the bank’s progress is not confined to one pocket of the franchise.
Automated services
Speed and automation add another layer to the case. E.SUN reported that loan income from its AI credit assessment model rose 37% year on year. Fully automated financial verification increased 60%, service application speed improved 50% and customer service waiting times fell 60%. These are the kinds of operational shifts that matter in a mature retail market. Customers notice the difference in how quickly they can complete a task and the bank gains efficiency at the same time.
What strengthens the profile further is that faster service has not been presented as a trade-off against control. E.SUN reported a mortgage non-performing loan ratio of 0.08% in the second quarter of 2025, which was 4 basis points below the average for Taiwan’s top 10 domestic banks. AI-based fraud alerts also increased the early capture rate from 23% to 38%. That helps make the broader retail story more credible. Growth and speed are easier to talk about than discipline, but they carry more weight when control remains visible.
The retail model also extends beyond lending decisions. E.SUN points to targeted marketing, digital consultation tools for mortgage enquiries and front-end architecture designed to handle surges in activity during volatile periods. These details help show the bank has been working on the wider operating environment around the customer journey and not just on headline products.
Holistic focus
The strongest case for E.SUN is that it has been improving several parts of the same retail franchise at once – lending has become more digital and more automated; cards have remained large in scale; service is now faster; and risk and fraud controls have stayed visible. That combination is more persuasive than a story built around one campaign or one specialist product.
The bank’s sustainability work also adds support to the wider retail profile, although it sits slightly outside the core banking spine. Its farm-to-table finance programme links funding to sustainable agriculture, traceability, certification and downstream food businesses. E.SUN reports supporting 171 producers and retailers, facilitating about NT$2.1bn in development funding and backing 272 hectares of eco-friendly farmland.
E.SUN has not relied on one standout product or promotional success. It has strengthened lending, cards, service delivery and control at the same time, which is a stronger sign of retail bank quality in a market where customers expect speed, simplicity and reliability as the standard.
