Abstract: This study examines the impact of climate change on food security in Bangladesh, focusing on rice production and its sensitivity to climatic variability. By linking precipitation and temperature to rice yields and incorporating these relationships into a trade regime‐switching partial equilibrium model, the research simulates future market conditions under alternative Shared Socioeconomic Pathways (SSPs). The analysis is divided into two parts: first, estimating yield variations for Bangladesh's two main rice harvests using historical weather data and stochastic simulations of future conditions; second, modelling the economic impacts of yield fluctuations under autarky and import parity regimes. The latter reduces the effects of domestic shocks but increases exposure to international market shocks. Climate variability interacts with trade regimes to determine food security outcomes: the effects on food availability and access, and the stability of food supplies, can be either nil or strong depending on the trade regime. The effectiveness of market interventions further depends on the trade regime in place, strengthening the case for more directly targeted support to food insecure households.
