France's fragmented National Assembly has left successive governments without a stable majority, driving repeated leadership turnover under President Macron. Sébastien Lecornu resigned after roughly a month in office when coalition talks collapsed over the 2027 budget and policy concessions, only to be reappointed days later with a mandate to finalize fiscal measures amid student protests over school conditions, surging fuel prices linked to external conflicts, and agricultural support needs. Traders assess his tenure against near-term parliamentary votes, potential censure motions from opposition groups, and scheduled budget debates, where failure to secure cross-party support could accelerate another change before year-end deadlines or the 2027 presidential cycle.
