Will South Korea GDP growth in Q2 2026 be between 3.5% and 3.9%?

Note: only 6/8 ensemble models completed on this run.

Analysis

The 60-point gap between ensemble (26.8%) and market (87.1%) is driven by two low-side agents anchored to stale annual forecasts and a mismatched q/q base-rate brief. My verification killed their case: Korea's finance ministry just raised its 2026 forecast to 3.0%, ING forecasts Q2 'well above 3%' YoY, CEIC nowcasts 3.885%, and carryover arithmetic makes 3.5-3.9% the clear modal band. So I side much closer to the market than the ensemble — the ensemble number should NOT stand. However, the market's 87% implies near-certainty that q/q lands in a ~0.4pp window (roughly 0.75-1.15%), while recent forecast errors on Korean quarterly GDP have been 0.5-0.8pp (Q1: actual 1.7% vs 0.9% consensus) and the chip boom creates real upside tail into the 4.0-4.4% bucket (priced only 3%, which looks too low). My independent fair value is ~55-70% (I set 0.62). That implies the market is somewhat rich, but the edge is not verifiable enough to trade against — traders may have fresher BOK-consistent nowcasts, and I could not find a July Reuters poll for Q2 2026 to pin the consensus. With ambiguity about the exact carryover (agents 3 and 6 disagree on it), two-sided miss risk, and no decisive verified fact favoring NO, the correct action is SKIP.
