The 12-month average stands at -0.34%, highlighting the sector’s uneven recovery.
Comparative performance
Compared to January 2025, output is down 2.7 percentage points. The volatility is pronounced: April 2025 saw a 2.9% surge, while June 2025 posted a -2.9% fall. These swings underscore the sensitivity of Korea’s industrial base to global demand cycles.
Policy pulse
With the index now below trend, policymakers face renewed pressure to support manufacturing. The Bank of Korea has signaled vigilance but refrained from immediate intervention.
