This is part two of a two-part series on capital flows across the Singapore-US and US-ASEAN corridors. As investment, trade and corporate expansion accelerate in both directions, the US-ASEAN corridor is emerging as one of the world’s most important growth corridors, reshaping how businesses invest, operate and scale across borders.

The US–ASEAN corridor enters a new phase

Home to approximately 684 million people and a combined GDP of around USD3.9 trillion, the Association of Southeast Asian Nations (“ASEAN”) is one of the world’s largest and most dynamic economic regions. ASEAN aims to promote economic and security cooperation within the region and currently consists of 11 member countries: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor-Leste and Vietnam.

The economic relationship between the US and ASEAN is key to both parties, with the scale of the relationship reflected in both trade and investment flows. The US is one of ASEAN’s largest sources of FDI, with over USD40 billion flowing into the ASEAN region from the US in 2024.  While FDI from ASEAN into the US is smaller, ASEAN is still an important trade partner. Over the past decade, bilateral trade between US and ASEAN has doubled and now exceeds USD550 billion annually.

This is further supported by policy alignment. Through frameworks such as the ASEAN–US Trade and Investment Framework Arrangement (TIFA), cooperation continues to deepen across areas such as digital economy, supply chains, infrastructure, energy transition and advanced manufacturing.

The result is a corridor that is becoming increasingly strategic for businesses seeking growth and access to opportunity across multiple markets.

US investment into ASEAN: Building the next growth platform

ASEAN’s appeal today extends beyond cost competitiveness. Supply-chain diversification, rising consumption and more sophisticated industrial ecosystems are strengthening the region’s position as an investment destination.

The trend is visible across several markets. Vietnam has become a major centre for electronics manufacturing, Malaysia continues to strengthen its role within the semiconductor ecosystem, and Thailand remains a key hub for advanced manufacturing and industrial production.

Increasingly, Singapore plays a pivotal role within this ecosystem. It serves as the region’s leading hub for treasury, capital, trade and regional headquarters functions, helping connect investment flows and business activity across Southeast Asia.

Large US corporates are noticing this change and adapting accordingly. Apple continues to expand production into Vietnam, adding 8 new supply partners in 2024 to bring the total number of vendors in the country to 35. HP has shifted portions of laptop production into Thailand, increased manufacturing capacity in Vietnam and recently invested in an AI audio company in Singapore. Similarly, Dell has broadened its regional production footprint and Intel continues to invest in Malaysia’s semiconductor packaging ecosystem.

For US corporates, ASEAN is now viewed not only as a manufacturing base, but also as a broader platform for growth and investment. As private consumption in the six largest ASEAN economies is projected to reach USD5 trillion by 2035, driven by rising affluence, urbanization and digital adoption, US corporates can capitalize on a growing customer base and market. The region’s combination of industrial capability, market opportunity and connectivity is making it an important part of long-term corporate investment strategies.

Of course, as operations extend across more markets, new risks may emerge. Companies need to ensure proper mitigation by coordinating capital, liquidity and decision-making across a wider network of suppliers, production centres and customers.

ASEAN investment into the US: Accessing demand, capital and innovation

The corridor story is not defined solely by investment flowing into Southeast Asia. Capital and corporate ambition are increasingly moving in the opposite direction as well. While ASEAN’s role in global manufacturing continues to strengthen, the US remains a critical destination for companies seeking scale.

As the world’s largest consumer market and one of the leading destinations for FDI, the US continues to attract businesses seeking access to customers, capital, innovation and deep capital markets.

This is reflected in the ambitions of ASEAN corporates. Across the region, companies are pursuing growth strategies that extend beyond domestic and regional markets.

Investment flows are expanding into sectors including artificial intelligence, digital infrastructure, advanced manufacturing, energy transition and logistics. Singapore-based investors, including Temasek, continue to identify the US as a priority destination, while regional champions are expanding through acquisitions, strategic partnerships and industrial investments.

Thailand-based Indorama Ventures, for example, has continued to build its US presence through large-scale industrial investments, demonstrating how ASEAN companies are using the US market to deepen capabilities and participate more directly in global growth sectors.

These developments reflect a broader shift. ASEAN companies are seeking not only to participate in global value chains, but also to capture a greater share of global markets. The experience of one ASEAN-based energy group illustrates how these ambitions are translating into real-world expansion across the corridor.

Implications for corporates

Across the US–ASEAN corridor, client conversations are evolving beyond market entry towards how CFOs and Treasurers can support growth, expansion and investment across multiple markets.

As supply chains become more distributed and growth opportunities become more international, efficient control of funding, liquidity and risk management is becoming a key enabler of corporate strategy. Otherwise, resilience can translate into trapped capital, longer cash conversion cycles and pressure on margins.

The companies best positioned to succeed will be those that can align production, capital and customers across markets while maintaining visibility, control and funding flexibility. CFOs and Treasurers play a core role in setting and executing expansion strategies across multiple jurisdictions and will continue to rely upon banking partners that can help them connect markets, and navigate regulatory and operational challenges.

Leveraging a longstanding presence across ASEAN and deep connectivity to major international markets, Standard Chartered is in a uniquely strong position to help clients operate across jurisdictions and support growth across the corridor.
