Climate change is likely to lead to more frequent and more severe supply and demand shocks that will present a challenge to monetary policy formulation. The main objective of the paper is to investigate how climate shocks affect consumer prices in a broad range of countries over a long period using local projection methods. It finds that the impact of climate shocks on inflation depends on the type and intensity of shocks, country income level, and monetary policy regime. Specifically, droughts tend to have the highest overall positive impact on inflation, reflecting rising food prices. Interestingly, floods tend to have a dampening impact on inflation, pointing to the predominance of demand shocks in this case. Over the long run, the dominant monetary policy paradigm of flexible inflation targeting faced with supply-induced climate shocks may become increasingly ineffective, especially in LIDCs. More research is needed to find viable alternative monetary policy frameworks.

Climate change is intensifying food insecurity across sub-Saharan Africa (SSA) with lasting adverse macroeconomic effects, especially on economic growth and poverty. Successive shocks from the war in Ukraine and COVID-19 pandemic have increased food prices and depressed incomes, raising the number of people suffering from high malnutrition and unable to meet basic food consumption needs by at least 30 percent to 123 million in 2022 or 12 percent of SSA’s population. Addressing the lack of resilience to climate change—that critically underlies food insecurity in SSA—will require careful policy prioritization against a backdrop of financing and capacity constraints. This paper presents some key considerations and examples of tradeoffs and complementarities across policies to address food insecurity. Key findings include (1) Fiscal policies focused on social assistance and efficient public infrastructure investment can improve poorer households’ access to affordable food, facilitate expansion of climate-resilient and green agricultural production, and support quicker recovery from adverse climate events; (2) Improving access to finance is key to stepping up private investment in agricultural resilience and productivity as well as improving the earning capacity and food purchasing power of poorer rural and urban households; and (3) Greater regional trade integration, complemented with resilient transport infrastructure, enables sales of one country’s bumper harvests to its neighbors’ facing shortages. The international community can help with financial assistance—especially for the above-mentioned social assistance and key infrastructure areas—capacity development, and facilitating transfers of technology and know-how.
