Fair Value Reasoning:

With less than 48 hours to settlement, weather forecasts have highly converged. The price collapse of '15°C' (falling from ~25c to 8c) confirms the departure of cooler air, shifting the forecast center firmly into the warmer zone. The market is currently deadlocked between '16°C' and '17°C' (both at 34.5c), which typically indicates that mainstream meteorological models (like GFS and ECMWF) are forecasting a value right on the margin (e.g., 16.5°C) or have slight disagreements. '18°C' retains 20% hedging value against better-than-expected solar heating. Meanwhile, the speculative bubble on '19°C or higher' has burst, returning to a tail risk probability.

Movers

March 17, 2026 - March 18, 2026, the price of '15°C' plummeted from 20c to 8c, and '19°C or higher' dropped rapidly from 18.5c to 6.5c. This was due to the approaching settlement date clarifying weather data, which ruled out cooler scenarios. Simultaneously, previous speculation on extreme heat subsided, causing the market to refocus on the core 16-17°C range. March 16, 2026 - March 17, 2026, the price of '17°C' surged from 17.5c to over 30c, driven by weather forecast models showing a clear warming trend.
