| dc.description.abstract | Kebijakan tarif impor Amerika Serikat tahun 2025 merupakan salah satu peristiwa geopolitik yang berpotensi memengaruhi pasar modal Indonesia. Penelitian ini bertujuan menganalisis reaksi pasar modal Indonesia terhadap empat peristiwa kebijakan tarif impor Amerika Serikat 2025, yaitu pidato Presiden Trump, pengumuman Liberation Day, penetapan tarif 19% untuk Indonesia, dan informasi penetapan tarif impor. Pendekatan yang digunakan adalah event study dengan market adjusted model pada tiga jendela peristiwa: (-1,+1), (-3,+3), dan (-5,+5). Objek penelitian terdiri atas sebelas indeks sektoral berdasarkan klasifikasi IDX-IC yang terdaftar di IDX dengan pengujian one sample t-test. Hasil penelitian terhadap abnormal return (AR) menunjukkan bahwa sektor barang konsumen sekunder memberikan respons paling konsisten di seluruh peristiwa, sedangkan sektor teknologi dan infrastruktur menunjukkan respons signifikan pada peristiwa tertentu. Hasil penelitian juga menunjukkan bahwa cumulative abnormal return (CAR) signifikan hanya ditemukan pada peristiwa pidato Presiden Trump pada jendela (- 1,+1) dan pemberlakuan tarif impor pada seluruh jendela peristiwa. Pola reaksi pasar yang bertahap mengindikasikan bahwa pasar modal Indonesia mencerminkan efisiensi bentuk semi-kuat yang bervariasi antarperistiwa dan antarsektor. | |
| dc.description.abstract | The United States import tariff policy in 2025 became one of the geopolitical events that potentially affected the Indonesian capital market. This study aims to analyze the reaction of the Indonesian capital market to four events related to the United States import tariff policy in 2025, namely President Trump’s speech, the Liberation Day announcement, the imposition of a 19 percent tariff on Indonesia, and information on import tariff determination. The approach used is an event study with the market adjusted model within three event windows: (-1,+1), (- 3,+3), and (-5,+5). The research objects consist of eleven sectoral indices based on the IDX-IC classification listed on the Indonesia Stock Exchange (IDX), using a one sample t-test. The results on abnormal return (AR) show that the consumer cyclical sector provided the most consistent response across all events, while the technology and infrastructure sectors showed significant responses to specific events. The results also show that significant cumulative abnormal return (CAR) was only found during President Trump’s speech within the (-1,+1) window and during the information on import tariff determination across all event windows. The gradual pattern of market reaction indicates that the Indonesian capital market reflects semi-strong form efficiency that varies across events and sectors. | |
