Korea and India Are Betting $720 Billion on AI. The Oil Runs Through Hormuz.

LG Chem shut down a cracker in late March. The reason was a petrochemical feedstock called naphtha — half of it imported through the Strait of Hormuz, and the strait had been effectively closed for weeks. South Korea designated the substance a "strategic commodity for economic security" and banned its export for five months ^[1]. This was the moment the energy crisis stopped being a macroeconomic headline and became a factory with its doors locked. The factory sits at the base of two of the largest industrial bets in modern Asian history. In Seoul, President Lee Jae Myung has committed $518 billion through Samsung and SK Hynix to build a chip-making hub targeting 80 percent of the global HBM market by 2028 — what he calls the "triple axis for a great leap forward" spanning semiconductors, physical AI, and AI data centers ^[2]. He has described the moment as a "golden window" for global AI dominance and issued a directive whose brevity captured the urgency.

Only speed matters. — Lee Jae Myung

The same directive mandates the "preemptive securing of critical power and water infrastructure to prevent construction delays" ^[3] — an acknowledgment, embedded in the order itself, that energy is the bottleneck on the ambition speed demands. In New Delhi, the government has laid out a sovereign AI roadmap committing roughly $200 billion through 2030, including more than $100 billion for data centers, alongside a 20-year semiconductor mission that recently expanded to cover specialty gases, chemicals, and materials — the very petrochemical inputs a Hormuz closure disrupts ^[4][5]. Energy Minister Vaishnaw lists "energy" as one of five critical layers of the plan ^[4]. AMCHAM India and Applied Materials have identified the electricity grid as "the single largest constraint on India's AI ambitions" ^[6]. India's data center capacity is projected to jump from 1.5 gigawatts to 13.5 gigawatts by 2031-32, and Cushman & Wakefield warns that "access to power, infrastructure readiness and delivery capability are becoming as important as demand itself" ^[7][8]. The four-month Hormuz blockade, which began February 28, did not kill either bet. But it spent the buffers both depend on, in three distinct ways. First, fiscal. South Korea deployed a $17.7 billion emergency budget to stabilize oil supply, dispatching envoys to Algeria, Libya, and Congo to scout alternative routes ^[9]. That is $17.7 billion absorbed by crisis management — capital unavailable for the kind of industrial investment the AI strategy requires. India, meanwhile, saw the World Bank cut its FY27 growth forecast from 7.2 percent to 6.6 percent and project the fiscal deficit widening to 7.6 percent of GDP, with Finance Minister Nirmala Sitharaman describing the Iran conflict as having "evolved from a regional security concern into a systemic tremor, threatening the vital arteries of global energy" ^[10]. Second, monetary. South Korean consumer prices hit a 21-month high in April, driven by a 21.9 percent jump in petroleum products and a 30.8 percent surge in diesel ^[11]. The Bank of Korea began deliberating rate hikes. Morgan Stanley documented the transmission across Asia: central banks including the Reserve Bank of Australia raised rates to combat imported inflation, polymer prices jumped 15 to 25 percent in two weeks, and 25 million tonnes of petrochemical capacity was curtailed ^[12]. Moody's made the mechanism explicit.

We now expect Brent crude in the $90-110 per barrel range for much of this year, with significant volatility, including occasional fluctuations outside this range in response to new developments. — Moody's Ratings

Higher borrowing costs for energy-intensive megaprojects are not a hypothetical downstream effect. They are the direct consequence of the rate-hike deliberations the inflation data has already triggered. Third, supply-chain. The naphtha export ban was the most visible break, but not the only one. South Korea's oil refining output plunged 19.4 percent in April — the steepest decline since 1988 — directly caused by Hormuz crude supply disruptions ^[13]. India's Semiconductor Mission 2.0, which targets 2-nanometer chip fabrication, has expanded its scope to include specialty gases, chemicals, and materials ^[5]. As one official put it, "The wafer is not made in India yet" ^[5] — meaning the inputs India needs to import are precisely the ones a Hormuz closure interrupts. The timeline makes the contradiction hard to dismiss. Samsung warns the HBM supply-demand gap will widen through 2027 ^[14]. The IEA warns that full shipping normalization through Hormuz may not arrive until 2027 ^[15]. The year the chip shortage is supposed to end is the same year the energy overhang may finally lift — meaning the ramp and the risk overlap exactly. The June ceasefire has collapsed oil from its $126 peak to roughly $71, and Morgan Stanley now forecasts a global surplus of 4.8 million barrels per day by 2027. But the relief rests on a 60-day memorandum, not a permanent settlement. Hormuz traffic has recovered to only 75 percent of pre-war levels. Iran attacked the Singapore-flagged container ship Ever Lovely on June 25, during the ceasefire, and the Persian Gulf Strait Authority warned that vessel security outside designated channels "is not guaranteed." Iran's parliament speaker, Mohammad Bagher Ghalibaf, has stated that Hormuz "will never return to the pre-war status quo." Neither country has structurally reduced its Gulf dependency. Forty to seventy percent of their crude passes through the strait. India's total oil cover is 50 to 60 days, against the IEA's 90-day benchmark, and its refineries are locked into medium-heavy crude that cannot be quickly switched ^[16]. South Korea raised its crude oil alert to the second-highest level on April 1, with domestic inventory down more than 20 percent; 70 percent of its oil originates from the Middle East ^[17]. The contradiction is not that the bets are reckless. It is that they are being made at maximum speed into a vulnerability that four months of blockade proved is structural, not temporary — and the fiscal, monetary, and supply-chain reserves those four months consumed are the same reserves a 20-year industrial transformation needs before it has broken ground. Lee Jae Myung's own directive contains the tension in a single sentence: maximum speed, and the acknowledgment that energy infrastructure is what will slow it down. The golden window and the energy crisis opened at the same moment. Only one of them has a ceasefire.
