FDI Flow
Japanese FDI to Thailand Trajectory
Japanese FDI to Thailand reached approximately USD 4-5B in 2023, still the largest single-country FDI source. However, Vietnam and India are capturing incremental Japanese electronics and automotive investment, creating moderate headwinds for Thai-corridor corporate-banking volumes.
Krungsri
MUFG Krungsri Integration
MUFG-Krungsri integration deepens with digital-banking investment and cross-border product sharing. Krungsri Finnovate (venture arm) and MUFG Innovation Partners create a fintech investment channel linking Thai and Japanese startup ecosystems through shared deal flow.
Digital
Corporate Digital Banking
Japanese corporate clients demanding treasury-management automation and FX-hedge digital portals. Mizuho and SMBC are investing in API-based corporate banking platforms to compete with KBank Business One and SCB Business Centre corporate-digital offerings.
