“…Even though there is an extended background theory on the determinants of bank deposits (Martinez-Peria and Schmukler, 2001;Hondroyiannis, 2004;Finger and Hesse, 2009;Oliveira et al, 2014;Nys et al, 2015;Anastasiou and Katsafados, 2020;Anastasiou and Drakos, 2021a;Anastasiou and Drakos, 2021b) the literature on forecasting deposit flows is still sparse. Especially, as far as we know, the only studies that conduct a forecasting exercise for bank deposits are these of Piscopo (2010), Petropoulos et al, (2018), and Anastasiou and Petralias (2021). In more detail, Piscopo (2010) developed a functional data model with ARIMA terms for forecasting the evolution of Italian bank deposits.…”
