The U.S. is experiencing the highest inflation in 40 years, and prices have been rising. The Fed adjusts this rate to achieve one goal - to maintain maximum employment and price stability in the United States. But the Fed's sharp rate hikes also raise the risk of a sharp slowdown, especially as new challenges emerge, such as Russia's war with Ukraine and China's capacity problems due to Covid lockdowns. This article assesses the impact of Fed rate hikes on the supermarket stock market. This paper builds a VAR model and an ARMA-GARCH model to analyze changes in stock prices from the perspective of value and volatility. This paper finds that Fed rate hikes unsurprisingly negatively impacted stock returns and increased their volatility, leaving stock prices in an unpredictable situation. The research paper can give the Fed a reference data. When the Fed decides to raise interest rates, it needs to consider the current world economic situation. For example, flu and war will affect the world economy, and will also have some impact when the Fed raises interest rates.
