Bidirectional causality relationship between Arabica offshore futures and spot market indicates market demand on Arabica coffee. In general, it’s identified unidirectional granger causality relationship between local and offshore futures market with information flows from the local futures market reflects the offshore market high expectation toward crop information during harvesting period both Arabica and Robusta. This is due to the importance of Indonesia’s coffee crop report to world aggregate coffee production.
