Four thousand acres of land in Tarlac Province, an hour’s drive north of Manila and known for its sugar and rice plantations, have lately become the object of a peculiar kind of national daydream.
Officials speak of “Golden Nodes” and “AI-native acceleration hubs,” advanced technology centers designed to speed up technology development. Investment bankers cite figures in the tens of billions of dollars. President Ferdinand Marcos Jr., in his fifth State of the Nation address on July 27, cast the project as the tonic an ailing economy has been waiting for.
The scheme in question, called Pax Silica, is quite possibly another overhyped industrial park. Unless, of course, it isn’t. And at this early stage, it all depends on whom you choose to believe.
“Pax” is Latin for “peace”, and “silica” refers to the mineral used in making computer chips.
Brainchild of U.S.
Pax Silica is a brainchild of the United States Department of State, which has a website devoted to this subject. Pax Silica was conceived in December 2025 to build a “secure, resilient, and innovation-driven technology ecosystem among allies and trusted partners”. Today it is a coalition of two or three dozen countries seeking to reduce their collective dependence on Chinese-controlled processing of the rare earths and minerals that feed modern chipmaking. It also proposes to manufacture and distribute computer chips.
One certainty is that Pax Silica is going to cost a lot of money — $40 billion to $70 billion, it is said. Some observers characterize it as a Philippine outpost of an American-led attempt to rewire the world’s semiconductor and critical-minerals supply chains — and it is arriving in a Philippine province whose water table, power grid and mining record are not designed to bear the consequences of such ambition.
Background
China refines roughly nine-tenths of the world’s rare earths, a chokehold it demonstrated with export controls in 2025 in response to American tariffs.
Rare earths are not really “rare”, just uneconomical to refine. They include scandium, yttrium, lanthanum, cerium, neodymium, praseodymium, samarium, europium, terbium, and dysprosium.
Pax Silica’s founding members — the United States, Japan, Australia, Singapore, South Korea, Israel and a handful of others — have since been joined by more than 30 countries in total, including several European ones eager for a hedge of their own.
After months of thought, the Philippines acceded in April, calculating that its deposits of copper, nickel, cobalt and gold, most of them barely explored, gave it something the coalition badly wanted.
That calculation has a domestic logic. Officials at the Department of Trade and Industry note that the country currently ships around four-fifths of its ore to China for refining, forfeiting the value that processing would add if done at home. The plan is to reverse that: to build refineries and packaging plants inside the Philippines rather than merely dig up the raw material and watch it sail away in Chinese barges.
Economic Security Zone
Pax Silica’s centrepiece will be a 1,620-hectare “Economic Security Zone” inside New Clark City. It will house semiconductor fabrication and advanced packaging alongside artificial-intelligence computing, mineral processing, logistics and housing — an entire industrial ecosystem summoned into being on land currently administered by the Bases Conversion and Development Authority.
The figures the BCDA has put on the table are, by any standard, extraordinary: $40 billion to $70 billion in eventual investment, up to 190,000 direct jobs, $200 billion in exports and tens of billions of pesos a year in tax revenue, all from an initial investment target of a mere $10 billion. Contract negotiations will run through this year, and planning will continue through 2027, with construction beginning in 2028.
Taiwan-based Foxconn, the world’s largest electronics contract manufacturer, reportedly has been lined up as an anchor tenant. Officials insist the arrangement remains a commercial one, governed by Philippine law, with two-fifths of the site set aside for parks and green space and no defence manufacturing or mining permitted within the zone’s own fences.
It is precisely that last caveat — no mining on site — that exposes the scheme’s central tension. The minerals destined for New Clark City’s refineries have to be dug up and processed somewhere, and the likeliest candidates are provinces such as Zambales, Palawan and Nueva Vizcaya, which have spent decades absorbing the deforestation and contaminated rivers that come with extraction.
Farmers’ groups, including the Kilusang Magbubukid ng Pilipinas, have accused the government of engineering a project whose environmental costs will be borne far from the boardrooms celebrating its economic ones. The mismatch between where value is captured and where damage accrues is not new in resource economics, but Pax Silica threatens to sharpen it considerably, given the scale of processing envisioned.
Local Resources
Then there is the matter of what resources the hub itself will consume. Estimates of its potential electricity appetite range from roughly 3 gigawatts to as much as 5 gigawatts once occupants are fully operational — on the higher end, close to a third of Luzon’s projected peak demand this year, and on a grid still heavily reliant on coal and exposed to shipping disruptions from conflict in the Middle East. Water forecasts run to some 130 million litres a day, comparable to the needs of more than half a million households, in a region already prone to shortages during El Niño years.
Local irrigation in Angeles, Capas and Tarlac would be competing, in effect, with some of the most capital-intensive industries on earth.
Sovereignty
Sovereignty is another live wire. Lawmakers from the left-leaning Makabayan bloc have highlighted reports that Washington sought special legal arrangements covering American personnel stationed at the site — but the Philippine government nixed that proposal.
Supporters counter that the coalition’s growing membership, now well beyond its original dozen, shows the arrangement functions less as an American protectorate than as a genuine multilateral hedge against a single supplier’s dominance — one that countries as varied as India and several European economies have judged worth joining on their own terms.
Even so, not every Philippine investment institution has rushed to embrace this one. The Maharlika Investment Corporation, manager of the country’s sovereign wealth fund, has said plainly that it sees no need to put its own money in, preferring to describe its role as facilitating rather than financing and betting that foreign direct investment will do the heavy lifting instead.
It is a modest but telling data point: The one Philippine vehicle explicitly designed to make strategic, patient bets on national priorities has, for now, opted to watch from the sidelines rather than co-invest.
Supply-chain “de-risking”
None of this guarantees Pax Silica will disappoint. Supply-chain “de-risking” has proven a durable theme in the West, and some countries — Vietnam and India among them — have shown that hitching a wagon to Western reshoring can genuinely accelerate industrialisation rather than merely flatter it. The project’s own timetable, with construction not due to begin until 2028, leaves time to resolve questions of grid capacity, water allocation and mining oversight before the first concrete is poured.
But grand strategy, once it lands on a specific patch of ground, tends to run up against arrangements that were never built with geopolitics in mind: irrigation schedules, coal-fired power plants, decades-old mining permits in distant provinces. Whether Pax Silica becomes the generational upgrade its champions promise, or merely the latest instance of ambition outrunning infrastructure, will hinge less on how many countries eventually sign the coalition’s charter than on whether Tarlac’s grid, water table and other resources can absorb the weight of everyone’s expectations at once.
