Forward Outlook
Scenario Analysis
- Bullish (30–40%): Sustained export demand and easing supply constraints keep YoY growth above 5% through Q2.
- Base (45–55%): Output moderates to the 2–3% range as one-off factors fade and global demand stabilizes.
- Bearish (15–25%): Renewed external headwinds or domestic disruptions push growth back toward zero or negative territory.
Risks and Catalysts
Upside risks include stronger-than-expected tech exports and fiscal support. Downside risks stem from global demand shocks, supply chain disruptions, or policy tightening. The Bank of Korea’s next moves will be closely watched, but the current data reduces the urgency for stimulus.

January’s 7.1% YoY print marks a dramatic reversal from December’s -0.3% and stands well above the 12-month average of 2.0%. The last time industrial production posted a comparable surge was in October 2025, when output jumped 11.6% YoY. Over the past six months, readings have swung from -8.1% in November to +7.1% in January, highlighting persistent volatility.
Such pronounced month-to-month shifts reflect both external demand fluctuations and domestic supply chain adjustments. The January rebound is particularly notable given the subdued readings through much of late 2025.
