The impact of China's economic uncertainty on commodity and financial markets

This paper use the SV-TVP-FAVAR model to analyze dynamic impacts of economic uncertainty on commodity prices, stock prices and their linkages. Results show that the whole and segmented markets of commodities have seen a fluctuating increasing trend in the time dimension with positive spillover effects in different periods. Agricultural products experienced a significant negative impact before the pandemic, but a significant positive impact after. There is an increasing positive spillover effect of China's economic uncertainty on the financial markets, with a long-term nature. Price linkages have a distinct non-linear characteristic, with long-term negative spillover effects dominating before 2017 and long-term positive spillover effects dominating after-wards, especially during the outbreak.
