Korea Exports Hit Record $86.1B as Chips Surge 151%, Naphtha Crisis Splits Manufacturing | April 2, 2026

Investment Implications

The Chip Boom and the Naphtha Crisis Are Tearing Korean Manufacturing in Two

In the same month that Korea's semiconductor exports surged 151.4% year-over-year — helping push the country's total monthly exports past $80 billion for the first time — the government restricted fuel exports and imported Russian naphtha for the first time this year. Within Korean manufacturing, energy dependence is now the line between winners and losers.

Korea's March exports hit a record $86.13 billion. Semiconductors accounted for $32.83 billion of that — the first time a single product category crossed the $30 billion mark — with a 151.4% year-over-year surge. Explosive demand for HBM chips used in AI data centers has been the catalyst: Korea's semiconductor production index jumped 28.2% month-over-month in February, the largest increase since 1988.

On the other side of the manufacturing divide, a very different story played out. After the Strait of Hormuz was effectively blocked, naphtha supply bound for Korea was cut off. The government imposed gasoline and diesel export restrictions on March 13, allocated KRW 469.5B in its supplementary budget for naphtha import subsidies, and brought in the first Russian naphtha cargo of the year at Daesan Port. For Korea's petrochemical industry — already deep in restructuring amid global ethylene overcapacity — feedstock supply disruptions are piling on.

This divergence is not temporary. Semiconductors have a relatively small energy cost as a share of revenue and enjoy an independent growth engine in AI demand. Petrochemicals, by contrast, use naphtha as a raw material input — when oil prices rise, costs rise in lockstep. According to IEEFA, Indonesia's coal-fired power generation costs rose 48% between 2020 and 2024. The pattern is clear: the more fossil-fuel-dependent the industry, the faster its cost structure deteriorates during an energy crisis. Korea's role as a strategic complement in advanced manufacturing continues to grow amid the US-China rivalry. If these trends persist, the gap between semiconductors and petrochemicals is likely to widen further.

Samsung Electronics and SK Hynix have each rallied over 50% year-to-date, and analysts note that KOSPI excluding these two names sits around the 3,900-4,000 level. South Korea's benchmark KOSPI index surged 8.44% on April 1 to close at 5,478.7, but the real beneficiaries of this rally are the sectors immune to the energy crisis. Petrochemicals and refining still face an uncertain path to margin recovery when securing naphtha and crude oil supply itself remains in question. The restructuring timeline for Korea's petrochemical complexes at Yeosu, Ulsan, and Daesan is the first signal worth watching.
