Financial abuse is a significant form of elder maltreatment and is frequently ranked in the top two most common forms of abuse perpetration. Despite this, it is under-identified, under-reported and under-prosecuted. Financial institutions, such as banks, are important environments for identifying and responding to the financial abuse of older people. Traditionally, banks have not always been part of inter-sectorial responses to financial abuse, yet are important stakeholders. The aim of this study is to explore perceptions and experiences of financial abuse in five national banks. Data were collected from 20 bank managers and five members of the National Safeguarding Committee in the Republic of Ireland. Using thematic analysis, four themes were identified: defining a vulnerable adult; cases of financial abuse of vulnerable adults; case responses to financial abuse of vulnerable adults; and contextual issues. The data demonstrate the multiplicity of manifestations and the complexity of case investigation and management. Findings point to the need to enhance banks’ responses, through additional education and training, and promote integrated inter-sectorial collaboration. In addition, a change in societal beliefs is needed regarding financial entitlement, responding to ageism, public awareness of the consequences of financial decisions and types of financial abuse, as well as ensuring such crimes are addressed within the legal system.
