Abstract

In this study we attempt to understand how people manage their condition during uncertainty, such as the economic crisis induced by the Covid-19 pandemic. In short,  we analyze the relationship between self-control, good financial behavior, and financial threat perception at the onset of the Covid-19 pandemic. A web-based survey was conducted to collect the sample (n = 589) in Indonesians people. This study found that self-control not only encourages good financial behavior but also reduces financial threat perception in the middle of uncertainty. However, good financial behavior cannot mediate the effect of self-control and financial threat perception. Our study provides evidence that at the onset of a financial crisis, self-control is needed to cope with acute stress that arises from sudden uncertainty. Having good financial behavior cannot fully alleviate financial threat perception. Self-control has a direct mechanism in coping with financial threats during COVID-19.Keywords: personal finance; self-control; Covid-19; pandemic; financial stress

The performance of Islamic bank consist of capital adequacy ratio (CAR), non-performing financing (NPF), profitability as measured by return on assets (ROA), return on equity (ROE), and net operating margin (NOM)., operating expenses to operating income ratio (OEIR) and financing to deposit ratio (FDR). The population in this study were 13 Islamic commercial banks operating in Indonesia. From this population 12 banks were taken as samples and one bank was not taken because the data were incomplete. The data is taken quarterly, namely 4 quarters before the pandemic and 3 quarters during the pandemic. To test the hypothesis, the independent sample t-test was used. The results showed that the profitability as measured by ROE and NOM has a significant effect, as well as the financing to deposit ratio is also significantly different. Meanwhile, CAR, NPF, ROA, and OEIR were not affected by the Covid-19 pandemic
