Between April 26, 2026, 05:13 and 06:18, multiple options experienced drastic price changes: the 37°C option plummeted from 31c to 3c, the 36°C option crashed from 35.5c to 11.5c, the 35°C option dropped from 37.5c to 22.5c, and the 32°C option fell from 17.5c to 2c. The reason is that as the date approaches, updated weather forecast models have confirmed a higher probability of rain in Manila on April 28. This significantly reduces the likelihood of extreme high temperatures (above 36°C) or unseasonable lows (below 32°C), causing market expectations to rapidly converge toward the 33°C-34°C range.
