Using a sample of 141 banks in Indonesia during the 2004–2018 period, we investigate the impact of financial technology (FinTech) firms on bank stability. We find that more FinTech firms tend to enhance bank stability regardless of types of FinTech firms and the measurement of bank stability. Meanwhile, we also find that small banks and non-listed banks tend to benefit more from the presence of FinTech firms. Specifically, small banks and non-listed banks exhibit lower riskiness and higher capital ratios following an increase in the number of FinTech firms. This paper, therefore, emphasizes that FinTech development might be beneficial for financial stability, particularly when FinTech companies with small banks or non-listed banks.
