Studi yang meneliti hubungan antara harga minyak dunia dan harga komoditi pangan di pasar domestik masih jarang ditemukan. Dengan membuat Model Panel Data dari 34 provinsi di Indonesia pada tahun 2010-2017, studi ini bertujuan untuk menginvestigasi pengaruh perubahan harga minyak dunia terhadap beberapa harga komoditi pangan lokal (kedelai,import, kedelai lokal, beras lokal, dan jagung lokal). Penelitian sebelumnya menemukan bahwa harga komoditi pangan lokal di beberapa negara tidak dipengaruhi oleh harga minyak dunia; akan tetapi, penelitian ini, dengan mengendalikan faktor – faktor lainnya yang dapat mempengaruhi harga pangan lokal, menemukan hasil yang berbeda. Hasil dari studi ini mengindikasikan bahwa harga minyak dunia dapat mempengaruhi harga pangan lokal di Indonesia melalui tingginya biaya pengiriman pada aktivitas impor. Selain itu, harga komoditi pangan dunia juga terbukti dapat mempengaruhi harga seluruh komoditi pangan lokal yang diteliti, yang mengimplikasikan bahwa harga komoditi pangan di Indonesia dipengaruhi oleh kondisi pasar internasional. Hasil dari studi ini memberikan masukan bagi pembuat kebijakan di Indonesia untuk mempertimbangkan perubahan harga minyak dunia dan harga komoditi global dalam menstabilkan harga komoditi lokal di Indonesia, terutama komoditi yang diimpor.
Globally, studies examining the nexus between global crude oil price and food commodity prices in domestic markets are scant. Employing panel data model of 34 provinces in Indonesia from 2010 - 2017, this study investigates the impact of global crude oil’s price change on some local food commodity prices (imported soybean, local soybean, local rice, and local maize). Previous studies found that local food commodity prices in some countries were not affected by global crude oil prices; however, this study, by controlling other factors which could affect local commodity prices, finds different results. This study’s findings indicate that global crude oil price could affect local commodity prices in Indonesia due to higher shipping cost in import activity. In addition, global commodity prices are also proved to affect all commodities examined in this study which implies that local food commodity prices in Indonesia are influenced by international market. The results of this study provide input to policymakers in Indonesia to consider the movement of global crude oil price and global commodity prices in stabilizing local food commodity prices in Indonesia, especially the imported commodities.

The lag value of each independent variable may be used to define the significance value of the Indonesian stock market, the rupiah-dollar exchange rate, and the price of crude oil in the VAR test. The shock brought on by COVID-19 tends to be steady in the short run as measured by the impulse response value and variance decomposition, but over the long term, the Indonesian stock market index and crude oil prices stay stable while the rupiah-dollar exchange rate has grown. Granger's causality test demonstrates that verified COVID-19 instances are responsible for alterations in the Indonesian stock exchange index and crude oil prices. However, there was no discernible causal link between verified COVID-19 instances and the rupiah-to-dollar exchange rate."
