Singapore’s Capacity Limits Redirect Data Center Growth to Malaysia, Fitch Says

Singapore’s tight data center capacity is expected to push significant growth toward neighboring Malaysia, according to a new note from Fitch Ratings released Wednesday. The rating agency said the city-state’s provisional allocation of 200 megawatts (MW) of new data center capacity falls well short of the demand reflected in competing proposals under the country’s Data Centre – Call for Application initiative.

Fitch expects much of the unmet demand to shift to the Malaysian state of Johor, reinforcing its view that infrastructure availability, rather than demand, will increasingly shape growth in the Singapore-Johor corridor. The corridor illustrates a broader regional trend, the agency noted, with infrastructure constraints setting the pace of expansion as computing needs surge across Asia Pacific (APAC).

Much of the announced capacity in APAC remains at the planning stage, with project delivery hinging on utility connections, land availability, permitting, financing, and equipment supply. From a credit perspective, high entry barriers, low vacancy rates, and strong spillover demand continue to support existing assets, particularly those with robust connectivity and expansion optionality. However, new supply faces elevated completion risk as power availability, grid upgrades, equipment lead times, and sustainability requirements become more binding constraints.

“We expect this to favor operators, landlords and infrastructure providers with secured utility access, established customer relationships and proven delivery capabilities, while speculative developments are vulnerable to delays, cost inflation and regulatory change,” said Fitch.

Singapore ranks among APAC’s most attractive digital infrastructure markets, but developers are becoming more selective, the agency said. Power availability and stricter sustainability standards are influencing where and how capacity is built, while land scarcity is concentrating development in designated locations. These factors raise entry barriers and slow supply responsiveness. CBRE estimates occupancy above 95 percent in the first half of 2026.

“We forecast tight market conditions for the remainder of 2026, despite additional capacity approvals, given rapid absorption and long lead times,” Fitch said. “These conditions should continue to favor existing operators, given limited available capacity and long lead times for new supply.”

Singapore’s supply constraints are also driving demand to nearby markets, with Johor emerging as the clearest beneficiary. The state offers proximity, lower development costs, and closer integration through the Johor-Singapore Special Economic Zone. Operational information technology (IT) capacity in Johor reached 1,110MW in the first half of 2026, according to Cushman & Wakefield, with a further 602MW under construction and 2,486MW planned. While colocation vacancy fell to 0.7 percent, indicating strong absorption of existing capacity, Johor retains a substantial development pipeline to accommodate further growth.

However, Fitch noted that Johor’s ability to sustain this momentum will depend on resource management and infrastructure delivery. Malaysian authorities have tightened requirements around power efficiency, water use, and renewable-energy adoption as the market scales. These measures may moderate the pace of capacity additions and lift development costs, but they should also buoy the market’s long-term resilience and sustainability by imposing greater discipline on project development.

“Demand fundamentals across the corridor remain favorable. Cloud adoption, enterprise digitalization and artificial intelligence (AI)-related workloads continue to support capacity expansion, although the timing and location of new development will increasingly depend on infrastructure availability and project execution,” said Fitch.
