This study investigates how public agricultural expenditure can mitigate the effect of climate variability on banks’ agricultural credit supply in sub-Saharan Africa. Data was collected from 23 countries over the period 2006 to 2021 and analysed with the two-step generalised method of moments. The study found that banks exhibit dynamic agricultural credit supply behaviour, with temperature variability negatively effecting it and precipitation positively. In the presence of public agricultural expenditure, the influence of temperature variability on agricultural credit supply is not significantly mitigated, although the effect of precipitation is mitigated.
