This stacked bar chart shows Net Portfolio Investment flows (equities, bonds, etc.) in ASEAN-5 countries: Thailand, Philippines, Malaysia, Indonesia, and Vietnam.
Key Observations:
2016–2019 mostly positive: Indonesia and the Philippines received substantial portfolio inflows during this period.
Post-2020 shift to outflows: A sharp reversal began in 2020, with Malaysia, Indonesia, and Thailand showing major outflows through 2022–2023.
2024 still weak: Malaysia is projected to see significant outflows again, suggesting continued global risk aversion.
Implication:
Portfolio investment in ASEAN-5 is highly sensitive to external shocks and global financial conditions. Unlike FDI, these short-term capital flows are volatile and reflect structural weaknesses in capital market depth and investor confidence.
