During COVID-19, the social environment influenced factors, including monetary policy, precipitation, temperature, exports, imports, tariffs, inflation, and household incomes, resulting in the fluctuation of coffee pricing. This paper selects US Coffee C futures as the benchmark of global coffee pricing, with the US as the representative of the exporting country and Brazil as the representative of the importing country. Based on the data collected from Brazil and US from 2015 to 2022, the research found the following: (1) Before the COVID-19 pandemic, the relationship between the US & EU tariffs and coffee pricing showed a positive trend due to the increase of substitutions' price. Monetary policy, delegated by the exchange rate of BRL against USD, indicates a negative direction toward coffee pricing. This is because it changes the value of coffee beans. Also, the import of coffee beans from Brazil to the US is slightly positively related to coffee pricing since the demand for coffee beans in the US exceeds Brazil's supply. (2) Combined with what is mentioned in (1), the following three factors most affect the COVID-19 social environment. The EU tariffs are becoming insignificant due to general and preferential rates converging. Because the monetary policy has lost much of its ability to influence local markets, it becomes unimportant to global coffee pricing. Meanwhile, international import from the US and export from Brazil becomes relevant to coffee pricing because of the transportation and Brazilian production problems.
