Does China’s Foreign Exchange Market Volatility Affect Agricultural Loan Market Volatility?

Background and Aims: China's foreign exchange (Forex) market has become increasingly volatile due to global economic shocks and domestic financial reforms. This volatility poses potential systemic risks to interconnected markets, including the agricultural loan market. Given the centrality of agriculture in China’s export profile and its dependence on specialized credit mechanisms, understanding how foreign exchange fluctuations impact agricultural finance is critical. This study investigates whether volatility in China’s foreign exchange market generates spillover effects on the agricultural loan market. It specifically explores the direction and time-varying nature of these effects and examines the mediating role of agricultural exports in this transmission process. Methodology: A Time-Varying Parameter Stochastic Volatility Vector Autoregression (TVP-SV-VAR) model is employed to analyze quarterly data from Q3 2011 to Q4 2023. The model integrates three variables: Forex volatility (measured via RMB/USD parity rate log returns), agricultural exports (from the Ministry of Commerce), and agricultural loan market volatility (based on adjusted loan balance data). Bayesian inference and MCMC methods are used for robust parameter estimation. Results: The findings indicate that Forex market volatility exerts significant but predominantly negative effects on agricultural loan market volatility in the short- and medium-term, challenging conventional expectations of positive spillovers. Agricultural exports, however, respond negatively to foreign exchange shocks, while their recovery has a positive impact on agricultural loan volatility. These results confirm that exports serve as a critical transmission channel. Policy resilience—via credit guarantees and export subsidies—helps buffer short-term effects, although systemic risks accumulate over time. Conclusion: Foreign exchange volatility influences agricultural loan markets in a dynamic, time-varying manner, with agricultural exports acting as a key conduit. While China's policy interventions have mitigated immediate impacts, long-term resilience demands adaptive strategies. These insights offer valuable guidance for policymakers seeking to enhance financial stability in sectors vulnerable to external financial shocks.
