South and Southeast Asia are well positioned to capture the economic opportunities arising from the global data center boom, but the long-term credit benefits will depend on how effectively countries turn infrastructure investment into broader, locally anchored economic growth, Moody’s Ratings said on Tuesday.

The region’s combination of high trade openness and rapid digital adoption is supporting strong demand for digital infrastructure, with large-scale data center investment expected to boost economic growth and employment through 2030, the rating agency said in a report.

However, Moody’s said the benefits would be uneven across countries and front-loaded during the construction phase, while high import content, limited employment creation and rising demands for power and water could constrain the economic multiplier.

“Capital spending boom will support gross domestic product (GDP） growth, but gains are constrained,” it noted.

Moody’s expects data center construction to continue beyond 2030, although at a slower pace, meaning the direct contribution from construction to GDP growth will gradually fade.

The more durable credit upside will instead come from the development of local digital ecosystems, including greater cloud adoption, digital services exports and the localization of equipment suppliers and specialist service providers.

Moody’s said the region is particularly well placed to benefit from the expansion of digital trade.

ASEAN’s digital services exports grew faster than non-digital services and goods between 2013 and 2024, while India’s digital services growth has also accelerated in recent years, it added.

“These trends support demand for digital infrastructure, but attracting capital is only the first step,” it said.

The agency identified three main channels through which the data center build-out could affect credit conditions: near- to medium-term macroeconomic growth, the financing and execution required to deliver planned capacity, and environmental resource constraints, particularly power and water.

For sovereigns, the implications include stronger growth, changes in external balances, fiscal incentives and potential contingent liabilities.

Project finance and infrastructure issuers are exposed directly through investments in data centers, electricity generation and transmission and distribution networks, while telecommunications companies, equipment suppliers and financial institutions would also benefit indirectly.

Malaysia, Singapore to capture largest economic gains

The economic impact of data center investment will vary significantly across S&SEA, with Malaysia and Singapore expected to capture the most material economy-wide benefits, said Moody’s

Malaysia stands out as the region’s strongest emerging-market beneficiary, with the country’s data center build-out expected to generate the largest relative gains in GDP and employment.

Moody’s said Malaysia has one of the largest planned data center investment pipelines in the region, with the economic impact concentrated particularly in Johor.

“This makes Malaysia the clearest case in the sample where the build-out can move the macroeconomic needle,” it said.

Singapore, meanwhile, is expected to derive a larger share of the benefits from data center operations and associated services rather than construction, reflecting its status as a mature digital infrastructure hub.

The city-state’s more constrained outlook for additional capacity, due to land and power limitations as well as sustainability requirements, means future gains will increasingly depend on extracting higher-value economic activity from its existing infrastructure.

Meanwhile, India has substantial planned investment and construction employment in absolute terms, but the impact remains relatively small compared with the size of its economy.

Thailand is expected to see a meaningful but limited uplift, while Indonesia’s large economy similarly means that even substantial planned capital spending would have only a modest impact on national GDP.

The Philippines remains an early-stage market, with its relatively small pipeline limiting the aggregate economic impact. However, Moody’s highlighted power availability and energy security as important constraints that could determine how quickly announced projects move into construction.

Vietnam currently has the smallest data center footprint among the markets covered, despite its strong information and communications technology goods export base.

Import dependence limits domestic multiplier

A key constraint on the economic benefits is the region’s dependence on imported equipment, according to the rating agency.

Data centers require large quantities of semiconductors, servers, cooling systems and other specialized equipment, much of which is not yet produced locally.

As a result, a significant portion of investment spending leaks out through imports, reducing the amount of value added retained domestically and potentially weighing on countries’ current account balances before additional digital services exports materialize.

Moody’s said data center-related imports have accelerated since 2023, particularly in India, Thailand and Vietnam.

Singapore and Malaysia are better positioned to retain more of the investment benefits because both already have significant semiconductor and electronics manufacturing bases.

India and Vietnam are also moving towards higher-value assembly, testing and packaging activities, which could gradually strengthen local supply chains.

Still, Moody’s said replacing fully imported advanced graphics processing units would remain difficult in the near term.

Employment gains are another constraint. Data centers are highly capital-intensive rather than labor-intensive, meaning most job creation occurs during construction, while permanent operational positions tend to be fewer and highly specialized.

Although governments are introducing training and certification programs, the employment and household-income effects are likely to remain weaker than those generated by more labor-intensive industries.

Ecosystem development key to lasting benefits

The strongest source of longer-term economic and credit benefits will therefore be the ecosystem that develops around data centers.

Moody’s said backward linkages could support suppliers of construction materials, critical minerals, electricity, fibre and water infrastructure, while investments in these areas could also improve service reliability and capacity for the broader economy.

Forward linkages could emerge once facilities become operational, supporting the clustering of data-intensive businesses, cloud adoption, artificial intelligence and digital services.

Greater digital infrastructure could also improve access to scalable technology for domestic companies, including small and medium-sized enterprises, potentially generating productivity gains.

The build-out could further attract foreign equipment manufacturers and specialist service providers while encouraging the development of domestic counterparts.

Moody’s said evidence of stronger digital services exports, wider cloud adoption and greater supplier localization would indicate that the credit benefits are becoming more durable.

Without these spillovers, the benefits would remain concentrated among data center operators, telecommunications companies and infrastructure providers.

Power, water remain key execution risks

The scale of the pipeline also creates significant execution and funding challenges, said Moody’s.

Grid connections, power generation, water availability, permitting, equipment shortages and skilled labor could constrain the pace of development.

Power infrastructure is particularly important. In India, data centers are expected to account for less than 5 percent of total power demand by 2030, giving the country greater capacity to accommodate incremental demand.

In Malaysia, however, data center demand could account for more than 30 percent of total power demand by 2035, making timely investment in both generation and transmission critical.

The energy mix also creates a tension between data center growth and decarbonization goals. Most regional power grids remain heavily reliant on fossil fuels, while opportunities for data center operators to directly procure renewable power vary significantly.

India is relatively better positioned because of its deeper renewable energy base and established corporate power market.

Moody’s expects water constraints to increasingly influence where and how data centers are built, but does not expect them to derail the region’s overall expansion.

Instead, water shortages are likely to raise costs, affect cooling technology choices and redirect projects towards locations with more reliable supplies.

Johor is cited as a clear example, with authorities tightening scrutiny of water availability, cooling design and alternative water sources.

The agency said cooling technologies such as dry, hybrid, closed-loop, direct-to-chip and immersion cooling could reduce freshwater consumption, although some carry higher capital or electricity costs.

It also highlighted Singapore’s approach, where resource-efficiency requirements are being integrated into its data center expansion strategy.

Policy will determine how much value stays local

Ultimately, Moody’s said policy design will play an important role in determining how much of the data center investment is retained domestically.

Fiscal incentives, resource-efficiency requirements, local skills development and infrastructure planning will influence whether the ecosystem benefits outweigh the costs of supporting the sector.

The agency said it will monitor several indicators, including whether GDP multipliers materialize as expected, the pace of new capacity additions, power delivery relative to planned capacity, tightening water and environmental requirements, and the tension between rising electricity demand and national decarbonization commitments.

For now, Moody’s expects the data center build-out to remain credit positive for S&SEA.

However, it cautioned that infrastructure investment alone will not guarantee durable economic gains.

For Malaysia and Singapore in particular, the ability to deepen digital services, attract higher-value supply chains and manage power and water constraints will determine whether the current construction boom develops into a longer-lasting source of economic diversification and credit strength, it said.
