The South Korean PPI’s 0.20% rise in November marks a moderation from the prior month’s 0.40% increase and remains above the mid-year lows of -0.40% recorded in June. Over the past 12 months, the average monthly PPI change has hovered near 0.15%, indicating a generally stable but slightly upward trend in producer prices. This moderation reflects easing cost pressures amid global supply chain normalization and subdued commodity prices.

Drivers this month

• Energy prices contributed 0.08 percentage points (pp), down from 0.15 pp in October.
• Intermediate goods prices rose by 0.07 pp, reflecting steady industrial demand.
• Durable goods prices added 0.05 pp, supported by domestic manufacturing output.

Policy pulse

The 0.20% MoM increase remains below the Bank of Korea’s inflation target corridor, signaling limited immediate inflationary pressure from producer prices. This supports the central bank’s cautious stance on further rate hikes, given the recent moderation in upstream price pressures.

Market lens

Immediate reaction: The KRW/USD currency pair strengthened by 0.30% in the first hour post-release, reflecting relief over the softer-than-expected PPI print. South Korean 2-year government bond yields fell by 5 basis points, while breakeven inflation rates edged down slightly, signaling tempered inflation expectations.

Producer prices are a leading indicator of consumer inflation and input cost trends. South Korea’s PPI growth has been volatile this year, swinging from a high of 0.60% in February to contraction phases in May (-0.10%) and June (-0.40%). The November reading of 0.20% suggests a return to moderate price increases but at a slower pace than mid-year peaks.

Historical comparisons

• November’s 0.20% rise is half the pace of October’s 0.40% increase, indicating cooling momentum.
• The 12-month average PPI MoM change is approximately 0.15%, showing that current growth is slightly above average but decelerating.
• Compared to the 2024 annual average of 0.35%, the current pace is subdued, reflecting easing inflationary pressures.

Monetary policy & financial conditions

The Bank of Korea has maintained a cautious tightening bias amid inflation concerns. The softer PPI print reduces near-term pressure on headline inflation, potentially delaying further rate hikes. Financial conditions remain moderately tight, with credit growth slowing and bond yields stabilizing.

Fiscal policy & government budget

Government spending continues to support economic growth, with fiscal stimulus targeted at innovation and export sectors. The moderation in producer prices may ease input cost inflation, helping to contain budgetary pressures on subsidies and social spending.

Market lens

Immediate reaction: South Korean bond yields declined post-release, reflecting market relief. The KRW strengthened modestly, while inflation-linked securities saw reduced volatility, indicating tempered inflation expectations.

Looking ahead, South Korea’s PPI trajectory will depend on several factors, including global commodity prices, supply chain normalization, and domestic demand conditions. The Bank of Korea’s policy decisions will hinge on whether producer prices accelerate or continue to moderate.

Bullish scenario (20% probability)

• Global commodity prices rebound sharply, pushing PPI above 0.50% MoM.
• Strong export demand fuels industrial price gains.
• Monetary tightening accelerates to contain inflation.

Base scenario (60% probability)

• PPI growth remains moderate around 0.15-0.25% MoM.
• Supply chains stabilize, limiting cost shocks.
• Monetary policy remains steady with gradual adjustments.

Bearish scenario (20% probability)

• Global demand weakens, causing PPI contraction.
• Commodity prices fall, easing inflation pressures.
• Monetary easing considered if deflation risks rise.

Structural & long-run trends

Long-term, South Korea faces structural inflation risks from aging demographics and wage pressures. However, technological advances and productivity gains may offset cost increases. Monitoring PPI trends will remain critical for anticipating shifts in inflation and growth dynamics.

The November 2025 PPI MoM reading of 0.20% signals a moderation in producer price inflation, consistent with a cautious economic outlook. While inflation pressures persist, the data suggests a balanced environment for monetary policy, with limited urgency for aggressive tightening. External risks, including commodity price volatility and geopolitical tensions, remain key uncertainties. Investors and policymakers should watch upcoming PPI releases closely as a barometer of inflation momentum and economic resilience.
