Abstract
This study examines the role of behavioral finance tools in shaping financial decision-making in Kazakhstan. While traditional finance theories assume rational behavior, real-world decisions are often influenced by cognitive biases such as overconfidence, loss aversion, and present bias. Using a qualitative approach and secondary data, the research explores how tools like nudges, framing, and default settings can address suboptimal financial behaviors in areas such as investing, retirement saving, and borrowing. The analysis highlights practical cases from Kazakhstan, including low stock market participation, the rise of cryptocurrency investing, and widespread consumer debt. Findings suggest that behavioral interventions can guide individuals toward more stable and informed financial decisions, but their effectiveness depends on cultural context and policy design. The study emphasizes the need for context-specific behavioral tools and offers policy recommendations to enhance financial well-being in Kazakhstan.
