Transatlantic security fragmentation deepening — US pressuring Europe over Hormuz support and defense spending while floating expanded nuclear sharing as reassurance. Adds European risk premium and fiscal/defence-spending implications; Macron legacy deteriorating.

Development timeline

• 2026-06-12 Jun 12: UK fiscal-defence fracture — Defence Secretary Healey and Armed Forces Minister resigned after Chancellor Reeves rejected a £28B ($37B) additional military-spending request; Healey was due to chair next week's NATO defence ministers meeting in Brussels, now leaderless. European defence-equity rally (BAE/Rolls-Royce/Rheinmetall/Leonardo) reversed on the UK funding failure; medium-term rearmament bid intact but near-term headwind. Revives this theme from staleness via concrete trigger.
