This paper presents priority areas where improvements are needed in the dependability of financial information systems by analyzing the current state of dependability for such systems. Focusing on accidents in financial information systems, which play an important role in the infrastructure of our information society, we first selected widely accident articles from four national major newspapers in Japan. Those accidents were examined from the viewpoint of financial information system dependability, and then categorized based on cause (referred to as "faults" in this paper). We then formulated a determination about the present state of the dependability of these systems, after which we proposed areas and issues related to financial information systems where dependability improvement is necessary.
