South Korea’s retail sales MoM fell by 0.70% in December 2025, according to the latest release from the Sigmanomics database.

Drivers this month
- Reduced spending on discretionary goods amid inflation concerns
- Lower sales in electronics and automotive sectors
- Stable but cautious household consumption on essentials
Policy pulse
The Bank of Korea’s recent rate hikes to combat inflation have tightened financial conditions, dampening consumer credit growth. Retail sales remain below the central bank’s inflation-adjusted target growth rate of 0.50% MoM, signaling restrained demand.
Market lens
Following the release, the Korean won (KRWEUR) depreciated slightly by 0.30%, while 2-year government bond yields edged up 5 basis points, reflecting market concerns over slowing domestic consumption and potential monetary tightening continuation.
Retail sales are a core macroeconomic indicator reflecting consumer spending, which accounts for roughly 55% of South Korea’s GDP. The 0.70% contraction in December contrasts with the 1.60% growth in November and the 12-month average of 0.20%, underscoring volatility in consumer demand.
Monetary Policy & Financial Conditions
The Bank of Korea has raised its policy rate by 125 basis points since mid-2025, aiming to curb inflation that peaked at 4.10% YoY in Q3. Tighter credit conditions and higher borrowing costs have weighed on retail sales, especially in durable goods.
Fiscal Policy & Government Budget
Fiscal stimulus measures have been modest, with the government focusing on targeted support for low-income households and SMEs. The 2025 budget deficit is projected at 2.80% of GDP, limiting expansive fiscal interventions to boost consumption.
External Shocks & Geopolitical Risks
Trade tensions with China and ongoing geopolitical uncertainties in the region have disrupted supply chains and consumer confidence. Export-driven sectors face headwinds, indirectly affecting domestic retail through income and employment channels.
Sector-wise, electronics and automotive sales declined by 1.20% and 0.90% MoM respectively, while food and beverage retail remained flat. This pattern suggests consumers are prioritizing essentials amid economic uncertainty.
This chart highlights a trend of weakening retail sales after a short-lived recovery. The data suggests consumer caution is rising, influenced by tighter credit, inflation pressures, and external risks. A sustained decline could signal broader economic slowdown risks.

Immediate reaction: The KRWEUR currency pair depreciated 0.30% within the first hour post-release, while 2-year government bond yields rose by 5 basis points, reflecting market concerns over slowing consumption and potential further monetary tightening.
Looking ahead, retail sales in South Korea face a mixed outlook shaped by domestic and external factors. The following scenarios outline potential trajectories:
Bullish scenario (25% probability)
- Inflation eases faster than expected, boosting real incomes
- Monetary policy pauses or eases in H2 2026
- Geopolitical tensions ease, improving trade and consumer confidence
- Retail sales rebound to 0.50% MoM by mid-2026
Base scenario (50% probability)
- Inflation remains sticky but manageable
- Monetary policy remains on hold with cautious tightening bias
- Geopolitical risks persist but do not escalate
- Retail sales hover near zero growth, averaging 0.10% MoM
Bearish scenario (25% probability)
- Inflation spikes due to supply shocks
- Further monetary tightening depresses credit and spending
- Geopolitical conflicts worsen, disrupting trade
- Retail sales contract further, declining by 1.00% MoM or more
Policy pulse
The Bank of Korea’s next moves will be critical. A hawkish stance risks deeper consumption weakness, while premature easing could reignite inflation. Fiscal policy remains constrained but could pivot if consumer demand falters sharply.
South Korea’s December 2025 retail sales data reveals a cautious consumer landscape amid tightening financial conditions and external uncertainties. The 0.70% MoM decline, while less severe than expected, signals a pause in the recovery momentum seen in November. Policymakers face a delicate balancing act between controlling inflation and supporting growth.
Structural trends such as digital commerce expansion and demographic shifts continue to reshape retail dynamics. Long-run growth will depend on innovation, labor market resilience, and geopolitical stability.
Investors and policymakers should monitor retail sales closely as a barometer of domestic demand and economic health. The interplay of monetary policy, fiscal support, and external shocks will define South Korea’s near-term trajectory.
