In short

  1. What is happening
    El Nino conditions have suppressed Atlantic activity, putting 2026 on track for one of the slowest hurricane seasons on record
  2. Why it matters
    A record-quiet Atlantic season cuts Florida carriers' catastrophe losses now and their reinsurance bill in 2027, the largest expense line they carry.
  3. What must hold
    Assumptions are statements that must stay true for the thesis to make sense.

The argument

The driver

El Nino puts a lid on Atlantic hurricanes through wind shear and a drier mid-level atmosphere, and 2026 is running as one of the quietest seasons on record. The climatological peak is 10 September. It has now passed without a major hurricane making landfall in Florida. There is still an October tail, and it is real, but the bulk of the distribution is behind us. That single meteorological fact resolves two separate economic questions for the small group of listed insurers whose entire book sits in the state.

What this thesis rests on

Each one is a statement that has to be true. We go back to every live thesis on a schedule and check these against public sources, so each leg carries either what we found or the date we look next.
