## Thesis

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.

## Watching

NATO Ankara summit July; whether nuclear-sharing talks become public; OAT spread on Macron deterioration; European defence fiscal expansion.

## Development timeline (dated, source-cited)

- 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. [Bloomberg]
- 2026-06-03: Two new independent data points Jun 2: Stoltenberg interview ('limits for what we should accept'; Trump calls NATO 'paper tiger' over Hormuz); FT exclusive on confidential US talks to widen nuclear deployments beyond 6 NATO host countries. [Bloomberg, FT]
