<![CDATA[This study aims to analyze the capital market reaction to events before and after the announcement of the 32% US tariff on Indonesia on manufacturing companies listed on the LQ45 index. Market reaction is measured through Abnormal Return and Trading Volume Activity with a quantitative approach using the Event Study method. The sample was determined using purposive sampling, with a sample size of six manufacturing companies listed on the LQ45 index for the period May-July 2025. The testing was conducted using a paired sample t-test and Wilcoxon signed rank test with an observation period of 7 days before and 7 days after the announcement. The results showed that there was no significant difference in abnormal return or trading volume activity before and after the tariff announcement. Thus, the announcement of a 32% tariff by the United States on Indonesia did not cause a significant reaction in the Indonesian capital market]]>
