May 7, 2026 - May 10, 2026, the 'May 15' option price fluctuated violently between 22.5c and 33.5c. As the term expiration approaches, short-term funds engaged in fierce speculation over the exact timing of his departure (whether he strictly completes all formalities before 11:59 PM on the 15th).
May 4, 2026 - May 5, 2026, the 'May 15' option price rebounded from 17c to 31.5c, as some capital bought the dip hoping for a strictly on-time departure.
April 30, 2026 - May 4, 2026, the 'May 15' option price plunged from 86.5c to 17c. This was due to the market reassessing the exact timing of his term expiration; since his term ends on May 15, he technically could retain the Chair title until 11:59 PM that day, sharply lowering the probability of the option resolving as 'Yes'.
April 28, 2026 - April 30, 2026, the 'May 15' option price surged from 25.5c to 86.5c, and the 'May 16' option surged from 62c to 85.5c, as the market rapidly shifted expectations to believe there is a high likelihood Powell will step down exactly upon his term expiration on May 15, rather than serving a prolonged period as Chair Pro Tempore.
April 24, 2026 - April 27, 2026, the 'May 31' option price surged from 44.5c to 85.5c, and 'June 30' increased to 96.4c. This occurred as the market reassessed the potential duration of Powell's holdover, increasingly confident that his official departure or the transition will be finalized by late May, correcting the previous days' overreaction.
April 21, 2026 - April 22, 2026, the 'May 31' option price plunged from 80.5c to 57.5c. This occurred as the market realized Powell might serve as 'Chair Pro Tempore' after his term expires on May 15 until a successor is confirmed by the Senate, potentially pushing his actual departure past May 31.
April 17, 2026 - April 21, 2026, the 'June 30' option price surged from 79.5c to 91c, and 'May 31' climbed from 67.5c to 80.5c. The market continued to digest the fact of Powell's term expiration in May, actively correcting the previous severe mispricing.
