**Introduction** The World Trade Organization (WTO)’s current mechanisms have left it lagging behind modern trade challenges because its core functions were designed for a system focused primarily on tariffs and border measures. Today’s trade frictions increasingly center on industrial subsidies, localization measures, export controls, and digital regulation. As these instruments have expanded in scale and strategic purpose, gaps in transparency, enforceability, and institutional flexibility have become more visible, limiting the WTO’s ability to discipline existing measures and update rules in line with contemporary trade policy practice[1][2][3]. **Institutional constraints limiting the WTO’s response to modern trade policy** **1.** **Subsidy disciplines are not calibrated for large-scale industrial policy** Under the Agreement on Subsidies and Countervailing Measures (SCM Agreement), transparency depends largely on members submitting timely and comprehensive subsidy notifications[3]. These notifications underpin peer review and allow members to assess whether support measures distort trade. However, industrial policy has evolved beyond traditional subsidy categories. Policy frameworks are increasingly incorporating production-linked incentives, tax credits, state-backed finance, and integrated sectoral support strategies designed to reshape supply chains and secure strategic industries[4]. As industrial support expands in scale and complexity, notification-based transparency struggles to keep pace. Where disclosure is incomplete or delayed, the WTO’s ability to evaluate cumulative trade effects weakens[3][4]. The expansion of subsidy competition across major economies has therefore outpaced the multilateral mechanisms designed to monitor and discipline it[4][5]. **2.** **Dispute settlement lacks effective appellate review** The Dispute Settlement Understanding establishes a two-tier process consisting of panel proceedings followed by appellate review. However, the Appellate Body has been unable to hear appeals since December 2019. Without a functioning Appellate Body, panel reports may be appealed without completion of review, preventing their adoption by the Dispute Settlement Body[2]. This reduces the binding effect of panel findings and weakens legal certainty under the WTO agreements[1][2]. In a system increasingly characterized by large-scale industrial measures and security-related trade actions, the absence of effective appellate review limits the capacity of the dispute settlement system to secure compliance and reinforce confidence in rule-based adjudication[5]. **3.** **Consensus-based rule-making slows adaptation to emerging disciplines** Decision-making under the Marrakesh Agreement operates by consensus[6]. While this ensures inclusiveness, it also constrains timely rule updates when regulatory approaches diverge. This is evident in areas such as digital trade and technology governance where negotiations under the Joint Statement Initiative on e-commerce have advanced among participating members, but incorporating outcomes into the WTO’s multilateral framework remains procedurally complex[7]. The growing reliance on plurilateral initiatives reflects structural constraints in consensus-based rule-making at a time when trade policy increasingly intersects with data governance, industrial strategy, and national security considerations[5][7]. **Conclusion** The WTO’s lag in addressing modern trade challenges reflects structural features of its institutional design. Subsidy disciplines rely on notification-based transparency that remains uneven; dispute settlement lacks effective appellate review, reducing the binding force and predictability of adjudication; and consensus-based decision-making slows the updating of rules in areas central to contemporary trade policy. As industrial policy, regulatory measures, and security-related trade actions assume greater prominence, these institutional constraints widen the gap between WTO commitments and members’ applied measures. The result is growing strain on the multilateral framework and increasing recourse to plurilateral initiatives and other alternative negotiating formats.
