Malaysia’s data centre market has become one of Southeast Asia’s fastest-growing digital infrastructure stories, projected to nearly double from $6.14 billion in 2025 to $11.4 billion by 2031, a 10.8% compound annual growth rate, according to ResearchAndMarkets’ analysis. But the pace of that expansion has now collided with physical limits Malaysia cannot simply build its way past.
The government has already started rationing growth
In February 2026, Malaysia began restricting new non-AI data centre investments specifically because of their electricity and water requirements, according to AMRO Asia’s analysis of the sector. That is a notable policy reversal for a government that has spent the past two years actively courting hyperscale investment — a sign officials now view grid and water capacity, not investor appetite, as the binding constraint on growth.
The economics were already tightening before that policy shift. Malaysia implemented new power tariffs for data centres in July 2025, first announced in December 2024, that could raise energy costs by 10% to 14%, with facilities above 100 megawatts facing the highest, “ultra-high voltage” tariff category, according to Business Wire’s coverage of the ResearchAndMarkets report.
Where the money is still flowing
Despite the constraints, capital keeps arriving. Microsoft announced plans in November 2025 for a second Malaysian cloud region — Southeast Asia 3, in Johor — expected to include three availability zones once operational, according to the ResearchAndMarkets report. NTT DATA is separately building a six-building data centre campus in Johor, having acquired land from Tropicana Corporation Berhad for roughly $88.5 million. Cyberjaya remains the country’s dominant hub, hosting more than 22 existing data centres with 9 more in the pipeline.
The upgrade in Malaysia’s 2026 growth forecast — to 4.7% from 4.5% — was explicitly tied to this investment wave. Hong Leong Investment Bank cited “continued investments in data centres” alongside strength in the electrical and electronics sector as key supports, with approved investments reaching RM431.1 billion in 2025 driven largely by information and communications technology inflows, according to Business Today Malaysia.
The real constraint: cost per megawatt
Building a data centre in Malaysia currently costs $8 million to $10 million per megawatt — cheaper than Singapore, which has long been the region’s default hub — but those costs are expected to rise 5% to 7% annually due to inflation, higher interest rates, and tightening regulation, per the ResearchAndMarkets analysis. That cost trajectory, combined with the new investment restrictions, suggests Malaysia’s cost advantage over Singapore may erode faster than headline growth figures suggest.
Why this matters regionally
Malaysia’s throttling of non-AI data centres is a preview of a constraint other Southeast Asian markets — and Gulf states pursuing similar AI infrastructure ambitions — will likely hit as global compute demand keeps outpacing grid buildout. The policy also has direct implications for the rare-earth and chip supply chain story unfolding in parallel (see our companion report on China’s export controls), since data centre expansion and semiconductor capacity are increasingly two sides of the same investment cycle.
