🧾 Executive Summary

The Bank of Korea (BOK) reported a 0.6% quarter-on-quarter GDP growth in Q2 2025, led largely by a 2.7% surge in manufacturing output. However, a cross-check with official monthly industrial production data from KOSIS reveals a sharp –2.9% contraction in May, raising serious concerns about the internal consistency and structural validity of the reported recovery.

📊 What Did the Bank of Korea Report?

“Manufacturing grew by 2.7% quarter-on-quarter, driven by electronic, semiconductor, and chemical products.”

This figure was echoed by media outlets like Reuters as “the fastest growth in over a year”:

🔍 The Problem: Contradictory Monthly Data

According to KOSIS, the Korean Statistical Information Service, the seasonally adjusted manufacturing production index for May 2025 shows:

• 🔻 –2.9% month-on-month

• 🔹 Index level (2020 base = 100): 110.5

📎 KOSIS – Industrial Production Index, May 2025

This steep monthly drop undermines the idea of a sustained quarterly recovery. Unless April and June recorded exceptionally strong rebounds, a +2.7% quarterly manufacturing expansion is statistically fragile.

📉 With falling equipment investment and contracting monthly output, it is difficult to reconcile the reported manufacturing surge with underlying industrial activity.

🧩 BBIU Hypotheses

1. Artificial quarterly rebound driven by favorable seasonal adjustment

2. Inventory offloading recorded as production in Q2

3. Optimistic framing ahead of strategic trade negotiations with the U.S. and Japan

4. Asymmetry between production-based and expenditure-based GDP measurement

🎯 Final Assessment

The +0.6% GDP figure for Q2 2025, while technically accurate in its own frame, does not reflect a solid or broad-based recovery. The underlying structure shows:

• Weak and inconsistent manufacturing data

• Continued decline in capital formation

• Mild consumption rebound

• Trade-driven growth concentrated in semiconductors and petrochemicals

In short, the recovery appears symbolic rather than structural.
