The ASEAN+3 region is expected to post economic growth of 4.0 percent in both 2026 and 2027, according to the annual regional economic outlook report released Monday by the ASEAN+3 Macroeconomic Research Office (AMRO).
The 2025 growth rate for ASEAN+3, comprising the Association of Southeast Asian Nations (ASEAN) member states and China, Japan, and the Republic of Korea, came in at 4.3 percent, higher than previously anticipated. The better-than-expected performance was driven largely by AI-driven semiconductor demand, which serves as a key engine of export growth, said the report titled ASEAN+3 Regional Economic Outlook 2026.
The report highlights profound structural changes underway in the ASEAN+3 economy. The region has now become one of the largest markets in the world, accounting for 28 percent of global final demand. At the same time, its reliance on the U.S. market has declined markedly, with the regional economy transitioning from a "manufacturing location serving external demand" to a regional market driven by domestic demand, according to the report.
The AMRO report also warned that escalating conflict in the Middle East and disruptions to global energy supplies significantly increase downside risks to the regional economic outlook.
The impact of the Middle East conflict on the region will depend largely on its duration. A prolonged conflict could trigger wider and more persistent shocks -- not only in energy markets but also across industrial inputs, logistics, food prices, tourism, and cross-border remittances, according to the report.
AMRO chief economist He Dong said that while Middle East tensions are already putting pressure on the region's energy supplies, the ASEAN+3 is better equipped to handle energy shocks than in the past. On the one hand, the regional economy has seen improved energy efficiency, with a reduction in oil dependence. On the other hand, inflation in the region is currently relatively low, and most economies still have ample policy space to respond to shocks, said the expert.
AMRO advises regional economies to maintain policy flexibility to guard against risks such as stagflation. Central banks should preserve financial market stability and take timely action if inflation continues to rise. Meanwhile, fiscal policy should focus on supporting vulnerable groups while avoiding the inflationary pressures and fiscal risks that large-scale stimulus measures could bring.
