**Recent cooling in South Korea’s headline CPI to 2.8% year-over-year in July 2026, following a 3.2% June reading, has kept the annual 2026 inflation outcome closely contested on Polymarket.** The Bank of Korea’s retained 2.7% forecast for the full year anchors trader focus around the 2.7–2.9% bin (32.6%), while the 2.4–2.6% (27.0%) and 3.0%+ (26.4%) ranges reflect uncertainty over whether moderating energy and food prices will offset demand-side pressures. The BOK’s back-to-back 25-basis-point hikes to 3% in July and August underscore persistent above-target inflation and core readings near 2.6%, reinforced by robust semiconductor-led growth now projected at 3.3% for 2026. Elevated global oil prices and pass-through of prior cost shocks continue to support higher outcomes, while August CPI forecasts near 3.1–3.3% could influence the remaining trajectory. Traders are weighing the central bank’s preemptive tightening and revised growth outlook against potential base effects and seasonal moderation. The tight clustering of the top three bins highlights how incoming monthly data and any further policy signals will determine whether the annual average aligns with, undershoots, or exceeds the BOK’s 2.7% projection.
