In capital markets, user experience (UX) isn’t just a design concern, it’s a performance lever. The stakes are high: users work fast, systems are complex and the risk of error is always present. Yet too often, UX becomes an afterthought, squeezed into the end of a sprint or retrofitted after delivery.
