This study addresses FinTech implementation challenges in the banking industry in Palestine. This was accomplished by adopting qualitative research methods. Semi-structured interviews were conducted with interviewees from the Palestinian Monetary Authority, banks, and FinTech companies. Thematic analysis was conducted using NVivo 12 software to identify themes in the interview scripts. Research outcomes suggest that FinTech development in Palestine encounters a range of multifaceted challenges, which can be categorised using the TOE (technological, organisational, environmental) framework. On the technological front, issues such as underdeveloped IT and telecommunications infrastructure, restricted mobile frequencies due to Israeli occupation, limited IT expertise, cyber risks, low digital literacy, and minimal FinTech awareness hinder progress. Organizationally, resistance to change, inadequate agility, limited digital skills, and slow Sharia compliance updates in Islamic banking impede innovation. Environmentally, the absence of a dedicated FinTech framework, unclear regulatory guidance, limited market size, and strict AML/CFT regulations create uncertainties for non-bank entities and restrict investment opportunities. Addressing these interconnected barriers requires coordinated efforts across legal, financial, and technological sectors to foster FinTech integration and growth in Palestine.
