Abstract: This article examines the transformative shift in financial services from traditional batch processing to real-time streaming architectures, with particular focus on wealth management and trading operations. The article explores how financial institutions are navigating this transition to enable instantaneous data processing and continuous integration of information flows. Through analysis of recent industry studies, the article identifies key technological enablers, including event streaming platforms, stream processing frameworks, cloud-native services, and time-series databases that form the foundation of modern financial systems. It further investigates the measurable business impacts of real-time processing across wealth management applications and trading operations, revealing significant improvements in client satisfaction, operational efficiency, and competitive differentiation. The research also addresses implementation strategies and organizational considerations essential for successful transformation, highlighting that comprehensive change management often proves more challenging than technical implementation. By synthesizing findings from multiple industry sources, this article provides actionable guidance for financial institutions embarking on the journey from batch processing to streaming-first architectures.
