The novel coronavirus pandemic has hit the Polish economy, including business activity. The paper aims to assess the impact of COVID-19 on the credit financing of microenterprises and farmers in Poland. We analyse investment loans and working capital loans, particularly the changes in the number and value of these loans, the number of loan enquiries, and the share of non-performing loans. The research period covers the two-year period, including the pre-COVID-19 subperiod from March 2019 till February 2020 and the COVID-19 subperiod from March 2020 till February 2021. We obtain monthly data from BIK. The BIK Group is the main source of credit and economic information in Poland. The study reveals a significant decrease in the number and value of investment loans and working capital loans during the COVID-19 period compared to the pre-COVID-19 period both in groups of microenterprises and farmers. Surprisingly, despite the difficult time for entrepreneurs, the COVID-19 pandemic significantly reduced the number of loans enquiries. As we expected, the number and value of non-performing loans increase due to the COVID-19 pandemic. However, the value of non-performing investment loans in the group of microenterprises increased marginally.Our research can be helpful for decision-makers and credit market participants, including national governments, financial market supervisory institutions, banks, and micro-entrepreneurs, and farmers.
