South Korea’s GDP rose 1.7% quarter-on-quarter in 1Q26, supported by strong chip exports and AI-related investment. ING raised its 2026 GDP forecast from 2.0% year-on-year to 2.8%.
Growth is expected to slow in 2Q26 as energy supply disruptions affect petrochemicals and other manufacturing sectors. The government introduced a temporary export ban on naphtha, and firms increased oil and gas imports from outside the Middle East, but full-capacity output remains constrained.
Semiconductors And Ai Drive Divergence
Prolonged disruptions could reduce chip production and dampen AI investment, given the economy’s reliance on semiconductors. Monthly inflation is expected to stay lower than in other Asian energy-importing countries due to government measures.
The Consumer Price Index is forecast to rise by at least 0.7% month-on-month in April, driven by higher energy prices and “chipflation”. Rising inflation expectations and uneven sector performance may limit policy flexibility.
In 2H26, the Bank of Korea is expected to face increased pressure to raise rates if growth remains above potential and inflation expectations continue to increase. The article states it was produced using an AI tool and reviewed by an editor.
Based on the strong first-quarter GDP figures, we are seeing a clear divergence in the South Korean economy. The powerful performance of chip exports and AI investment is creating bullish momentum in the tech sector. This suggests opportunities in long positions on tech-heavy indices or specific semiconductor stocks in the coming weeks.
Rate Pressure And Targeted Trades
However, this strength is offset by looming headwinds from energy disruptions which will likely slow growth in the second quarter. This K-shaped recovery, with tech outperforming while other manufacturing suffers, points towards increased market volatility. Traders should consider strategies that benefit from this uncertainty, such as buying options on the KOSPI 200 index.
The most significant factor for derivative traders is the growing pressure on the Bank of Korea to raise interest rates. With March inflation holding firm at 3.1% and a projected monthly increase of at least 0.7% for April, rate hike expectations for the second half of the year are solidifying. This makes shorting Korean Treasury Bond futures an increasingly attractive position to hedge against or profit from rising yields.
This policy divergence is also key for currency traders, especially when we recall the global rate environment of 2025 where major central banks were holding steady. With the Bank of Korea now leaning towards hiking while others remain neutral, the Korean Won (KRW) is positioned to strengthen. We see potential in long KRW positions against currencies like the US dollar, anticipating capital inflows seeking higher yields.
Finally, the government’s temporary Naphtha export ban creates a specific, short-term trade opportunity. This directly impacts the petrochemical and plastics industries, which rely on Naphtha as a feedstock. We believe traders should look at bearish positions on exposed companies in these sectors, as they are likely to face compressed margins and production cuts.
