SINGAPORE – Southeast Asia's six largest economies -- Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam -- are projected to grow by an average of 4.8 percent annually between 2026 and 2035, according to a report released on Wednesday.

Growth will be supported by sustained foreign investment and capital formation, continued industrialization and infrastructure development, and productivity gains from technology adoption, said a report by Bain & Company, DBS Bank and Vriens & Partners.

Resilient domestic consumption and favorable demographics in several major economies are also expected to provide support.

However, growth paths are diverging, with institutional strength, energy security and technological readiness shaping economies' ability to withstand shocks and capture opportunities.

Vietnam is expected to remain the regional growth leader, while Thailand lags its counterparts. Indonesia, the Philippines and Thailand face greater exposure in a downside scenario, while Malaysia, Singapore and Vietnam have greater upside under more favorable conditions.

Foreign direct investment has also surged, with shifts in the investor mix reflecting global supply chain realignment.

The report showed Singapore remains the region's most resilient economy, supported by its safe-haven status, deep markets, fiscal buffers and trusted hub credibility. Its position as a regional center for capital also facilitates investment and business opportunities across Southeast Asia.
