The Producer Price Index (PPI) in South Korea remained steady at 1.9% year-on-year for December. This stability shows consistent producer prices despite varying economic indicators, reflecting the health of the country’s economy. The unchanged PPI indicates that production costs aren’t facing strong inflation right now. Analysts will closely monitor global economic trends that might affect producer prices in the future.

Stability in PPI

The steady PPI could impact South Korea’s economic performance and future policy decisions. As the country navigates internal and external challenges, the PPI will be an important factor for policymakers to track. This information is vital for understanding the country’s economic path and may guide changes in monetary policy based on broader economic conditions. As of January 20th, 2026, we see that last month’s data shows South Korea’s producer prices stayed at a 1.9% annual increase for December 2025. This stability in wholesale inflation means the Bank of Korea is likely not feeling pressure to change its monetary stance. This supports our belief that the central bank will focus on promoting economic growth. The consistent producer price aligns with recent consumer inflation data, which also showed a decline to 2.1% last month. This is a significant drop from the higher levels around 3.0% seen in late 2024. The easing of price pressures at both producer and consumer levels strengthens the case for the Bank of Korea to consider lowering interest rates this year.

Potential Impact on Currency and Stocks

For traders dealing in derivatives, this outlook suggests the Korean Won might weaken against the US Dollar. We recommend considering USD/KRW call options that expire in one to two months, anticipating a rise toward the 1,380 level from its current position near 1,355. This strategy offers a defined-risk way to profit if monetary policy expectations lead to a weakening of the won. On the other hand, lower borrowing costs and steady input prices could benefit the South Korean stock market. We see potential in purchasing call options on the KOSPI 200 index to take advantage of any market rally that might occur due to expectations of a more accommodating central bank. Historically, periods of decreasing inflation after a rate hike cycle, like we saw end in 2024, have been good for equities. Currently, the KOSPI’s VIX-equivalent is trading near multi-year lows at around 14.5, meaning options premiums are relatively low. This makes it a cost-effective time to establish bullish positions through derivatives. Create your live VT Markets account and start trading now.
