US-Indonesia Trade Agreement and RCEP: Why Asian Supply Chains Need an Institutional Anchor

The US-Indonesia Trade Agreement and RCEP: Why Asian Supply Chains Need Institutional Anchors

On February 19, 2026, Indonesia and the United States signed the Agreement on Reciprocal Trade (ART), which Jakarta regarded as a relative “victory”: facing high punitive tariffs, Indonesian exporters at least gained breathing room with exemptions for 1,819 product lines and an additional tariff rate reduced to 19%. However, the next day, the U.S. Supreme Court ruled that key parts of the Trump administration’s tariff system were unconstitutional, and the legal foundation of the agreement immediately loosened. This dramatic reversal, far more than the agreement itself, illustrates the fundamental problem of the current global trade order—bilateral stability arrangements can be overturned at any time by domestic politics and judicial review.

Short-term relief may only be a painkiller

Indonesia’s annual exports to the United States are about $34.7 billion, and labor-intensive products such as clothing, footwear, and furniture are highly dependent on the U.S. market. If the additional 19% tariff were fully implemented, it would directly weaken the competitiveness of Indonesian products; on the other hand, the “tariff reduction buffer” prepared by ART does buy time for export enterprises. However, the logic of this agreement is fundamentally different from classic free trade agreements: Indonesia promises to eliminate tariffs on 99% of U.S. products and adjust some non-tariff measures, while the United States still retains the power to impose tariffs at any time on the grounds of domestic trade laws and national security laws. In other words, the United States has not truly incorporated Indonesia into a stable and predictable market access system; what Indonesia obtains is only a “temporary quota” adjusted according to administrative will.

The hidden erosion of regional supply chains by bilateral deals

The problem lies not only in the agreement itself, but also in its spillover effects. To obtain substantial preferential treatment, bilateral agreements often come with implicit conditions on procurement behavior, the use of rules of origin, and even investment flows. When Indonesian enterprises adjust their supply chain layouts to meet U.S. requirements, they may inadvertently deviate from the highly efficient division-of-labor network within Asia. Although this distortion does not directly violate RCEP rules, it will give rise to various special arrangements in the region and gradually weaken the convenience brought by unified rules of origin.

The competitiveness of Asian supply chains is built on a highly coordinated cross-border production system. If one link changes its procurement path due to political pressure, chain reactions may occur. More worrying, if such “one-to-one” arrangements become the norm, ASEAN countries will be forced to deal with the conditional demands of different major powers separately, and the difficulty of regional integration will rise exponentially. As an important member of ASEAN, Indonesia is both a hub of the regional production network and a potential victim of the fragmentation trend.

RCEP's strategic value: from rules to certainty

It is against this backdrop that the significance of RCEP for Indonesia and Asia as a whole has gone beyond tariff reduction. RCEP brings China, Japan, South Korea, Australia, New Zealand, and ASEAN into the same institutional framework, and its cumulative rules of origin allow enterprises to flexibly use inputs from member countries within the region without worrying about losing preferential eligibility due to insufficient origin ratios. For Indonesia, which is deeply involved in the global manufacturing value chain, this means a reliable regional production organization logic.RCEP is not the most radical trade liberalization experiment, but it provides precisely the scarcest resource in the current environment—certainty. When U.S. policies toward trading partners drift with electoral and judicial winds, and when the WTO Appellate Body remains paralyzed, RCEP's consultation and dispute settlement mechanisms offer regional members an institutionalized outlet for resolving conflicts within the agreement's framework. This certainty is a more important factor in cross-border investment decisions than a tariff reduction of a few percentage points.

Action Strategy: Making the Regional Framework an Irreplaceable Backbone

For Indonesia and other RCEP members, the real strategic priority is not to reject bilateral arrangements, but to ensure that the regional framework always remains at the core. Governments need to invest resources to raise RCEP utilization rates, especially by helping small and medium-sized enterprises overcome the thresholds of information, technology, and logistics, so that they can genuinely enjoy preferences under RCEP rules. At the same time, any newly signed bilateral agreement should undergo a "supply chain compatibility" test to avoid introducing provisions that cause production shifts or fragmentation of rules of origin.

Asia's production networks are under unprecedented external pressure. Bilateral agreements can only provide short-term tactical buffers, while the multilateralized, institutionalized regional economic cooperation represented by RCEP is the cornerstone of long-term resilience in the industrial chain. In a storm, the value of a solid port is not to temporarily shelter a single ship, but to provide predictable routes for the entire fleet.
