The Fdi Tailwind And Its Limits
Foreign direct investment into Asian manufacturing, measured on an announcement basis, has been at historically elevated levels since 2022. The reshoring and friend-shoring narrative generated a wave of manufacturing commitments across Vietnam, India, Indonesia, Thailand and Malaysia that the financial press characterised as a structural shift away from China.
The saturation thesis challenges this narrative. Not as a denial of the structural trend, which is real, but as a recognition that FDI announcements and FDI delivery are different variables with very different lag structures, and that several of the most prominent recipient markets are approaching genuine bottlenecks that could cause the FDI-to-output conversion ratio to fall sharply.
The desk's saturation framework has three inputs: labour market tightness (is the recipient market running out of the specific workforce needed for announced projects?), infrastructure utilisation (are ports, power grids and logistics networks at capacity relative to announced investment?), and regulatory throughput (can the permitting and land acquisition process keep up with investment demand?).
Vietnam
Vietnam's manufacturing FDI success story is well-documented. The country absorbed approximately USD 18 to 20 billion in manufacturing FDI in 2025 and now accounts for a significant share of global electronics, garment and footwear exports. Samsung, Apple's supply chain, Intel and LG all have major manufacturing operations in the country.
The saturation signals are visible in Vietnam's labour market data. Manufacturing wages in the northern industrial provinces (Hanoi, Bac Ninh, Hai Phong) have risen approximately 8 to 10 percent annually for three consecutive years. Labour turnover at major electronics manufacturers has risen to 20 to 25 percent annually, creating training and quality costs that are eroding the cost advantage. The rural-to-urban migration pool that fuelled manufacturing growth in the 2010s is showing signs of depletion in the northern provinces.
Power supply is the second constraint. Vietnam's electricity grid has experienced rolling industrial shortfalls in peak summer months for the past two years. The government's power development plan commits to significant renewable and grid expansion, but the timeline of 3 to 5 years means the constraint is binding for decisions being made today.
Vietnam manufacturing FDI is plateauing in the northern province cluster. New announcements are increasingly directed toward central and southern Vietnam, where labour and power constraints are less severe but infrastructure is less developed.
India
India's manufacturing FDI announcements have been very large: the government's PLI scheme, MISA's investment facilitation programme and the Prime Minister's direct engagement with global CEOs generated headline commitments of over USD 100 billion across 2023 to 2025.
The gap between announcement and production output is the investment community's central frustration with India. The lag between an FDI commitment and the first shipment of export goods is typically 3 to 5 years in India, compared to 18 to 24 months in Vietnam or 12 to 18 months in Mexico. The reasons: land acquisition process, environmental permitting, labour law compliance verification and infrastructure connection timelines.
As a result, India's FDI announcement data looks dramatically better than its FDI delivery data. The desk tracks actual manufacturing export growth as the more honest metric. That number is positive and accelerating, but it is consistent with a 2 to 3 year delivery lag from the 2023 announcement peak.
Indonesia And Thailand
Indonesia and Thailand are the two most significant second-tier manufacturing FDI destinations in Southeast Asia. They serve different niches: Indonesia is large-scale resource processing, base metals, battery materials and downstream chemicals; Thailand is automotive, electronics assembly and medical devices.
Indonesia's battery materials opportunity is its most important new FDI growth driver. The country holds approximately 24 percent of global nickel reserves and has implemented a nickel ore export ban that successfully attracted battery materials processing investment from Chinese, Korean and Japanese companies. The downstream processing complex is growing rapidly, and the next phase is lithium iron phosphate and NCM battery precursor manufacturing.
Thailand's automotive exposure is both its strength and its risk. The country is the dominant Southeast Asian automotive manufacturing hub, with major Japanese OEM capacity. The EV transition creates a specific risk: Japanese OEMs that dominate Thailand's automotive sector are generally behind on EV development relative to Korean and Chinese competitors. If Thai automotive capacity is retooled for EV production, the transition risk to existing Japanese JV structures is real.
Portfolio Implications
The saturation thesis argues for a rotation within Asian manufacturing FDI exposure: away from first-mover destinations approaching constraint (Vietnam northern corridor, India announcement-to-delivery arbitrage) and toward less-saturated second-tier destinations with specific bottleneck solutions.
The desk's preferred vehicle: Indonesian nickel and battery materials processors; Thai EV supply chain retooling beneficiaries; and logistics and port infrastructure operators in Tier 2 destinations. What to avoid: manufacturing FDI beneficiary equities priced for continued linear growth in announced capacity without accounting for the saturation lag.
