Forward Outlook
Scenario analysis
- Bullish (25–35%): PPI moderates below 1.5% by Q2 2026 as energy costs stabilize and supply chains normalize.
- Base (50–60%): PPI remains near current levels, fluctuating between 1.7% and 2.0% through mid-2026, with steady input costs and moderate demand.
- Bearish (10–20%): PPI accelerates above 2.2% if commodity prices surge or geopolitical risks disrupt supply chains.
Risks and catalysts
Upside risks include renewed energy price volatility and export-driven demand. Downside risks stem from global growth headwinds and potential currency appreciation dampening import costs. The Bank of Korea will closely monitor these dynamics for policy calibration.
