The Indonesia Economic Summit (IES) is the Indonesian Business Council (IBC) annual flagship event. IES is a high-level forum designed to bring together international business leaders, policymakers, thinkers, and industry champions. The forum explored Indonesia's current and future economic development, and how it becomes the new growth hub in the global landscape.

In 2025, IES addressed a wide range of important topics, including industrialization, fiscal and monetary policy, investment, food security, energy transition, state-owned enterprise reform, international market diversification, green protectionism, and human talent development. While also providing a platform for business leaders and strategic partners to explore future investment and collaboration opportunities through a dedicated executive roundtable.
