French PM Lecornu wrote a letter to the socialists, stating his willingness to discuss "three key areas" on which compromises can be made

This sits inside the familiar French minority-government playbook: a PM without a stable Assembly majority shopping for abstentions or support from a pivotal bloc, here the socialists, whose votes have repeatedly determined whether governments survive censure motions and pass budgets. The channel that matters for markets is not the substance of the three policy areas named, none of which touches the fiscal anchor directly, but what concession-making of this kind implies for the budget trajectory, since past episodes of minority-government horse-trading in France have tended to widen deficits relative to the original finance bill and have been the proximate driver of OAT-Bund spread widening episodes. The distinction worth drawing is between programmatic concessions, which cost money slowly, and procedural commitments on the budget calendar, which determine whether a government falls on a no-confidence vote; the former is what this letter signals. Socialist leadership in this position has historically extracted spending commitments in exchange for not bringing governments down, so the tell is whether the ask escalates toward pension or fiscal territory, which is where OATs and French bank paper have re-priced on previous occasions. The follow-ons are the socialists' formal response, any read-across to the finance bill amendments, and the spread behaviour in the 10-year sector rather than anything in EUR itself, which has generally treated French domestic politics as a rates story first.
