May 6, 2026 - May 7, 2026, the price of the 64-65°F option surged from 13.5c to 38.5c and then pulled back to 24.5c. This was caused by minor adjustments in short-term weather forecast models, causing market expectations to swing between 62°F and 65°F. May 6, 2026 - May 7, 2026, the price of the 60-61°F option dropped from 21.5c to 7.5c before recovering to 16.5c, reflecting similar expectation adjustments due to forecasting noise as the expiry approaches.

US CPI data is a crucial driver for Federal Reserve monetary policy. A higher-than-expected inflation print typically pushes up US 10-year Treasury yields and the US Dollar (DXY) as markets price in tighter monetary policy, while simultaneously pressuring broad equities (S&P 500) and triggering volatility in Gold. This constitutes a highly tradable macro event.
