Abstract:

Since the COVID-19, the continued loose monetary policies of various countries in the world have strengthened inflation expectations. Since inflation is always one of the important factors for investors to make investment decisions, the upward pressure of inflation will bring about the instability of the stock market, resulting in the dual fluctuations of prices and financial markets. Price stability and financial stability are important objectives of dual-pillar regulation. It is of great importance to clarify the relationship between inflation expectations and stock returns for the accurate realization of the target of dual-pillar regulation policies and investors' better avoidance of inflation risks.In the framework of a single commodity economy, the nonlinear relationships between stock returns and inflation expectations and inflation surprise are discussed in this paper. Furthermore, based on the asymmetric long-term and short-term perspective, the nonlinear autoregressive distributed lag (NARDL) model is applied to conduct empirical research.The empirical results show that the positive and negative changes of inflation expectation and inflation surprise have asymmetric effects on stock returns in the short and long term. The response of stock return to the negative change of inflation expectation or inflation surprise is greater, which indicates that the weakening of inflation expectation or inflation surprise has a more significant impact on stock return. The positive relationships between inflation expectation, inflation surprise and stock returns are mainly shown in the short term, and in the long term, inflation expectation and inflation surprise have a restraining effect on stock returns. It shows that stock investment can resist the inflation risk in the short term, but in the long term, stock investment is no longer an effective tool to resist the inflation risk.

Key words: inflation expectation, inflation surprise, stock returns, nonlinear, NARDL model
