French Prime Minister Sébastien Lecornu has resigned amid an intensifying political crisis, stepping down just one day after President Emmanuel Macron announced the new cabinet line-up and less than a month into his tenure. This marks the third prime minister to lose their post due to an inability to push key reforms through a fractured parliament. The events have sharply rattled French financial markets and sparked a fierce domestic political debate. Notably, Lecornu becomes the shortest-serving French Prime Minister in history, underscoring the severe uncertainty clouding the nation's future.
Reasons for Lecornu's Resignation
Lecornu tendered his resignation less than 24 hours after Macron unveiled a government in which most positions were filled by politicians from the preceding cabinets. This decision drew widespread criticism from an opposition that was expecting genuine change. In his statement, the former Prime Minister cited growing political polarisation and the impossibility of effectively executing his duties.
He highlighted the difficulty in pushing through a budget that includes unpopular spending cuts and tax hikes—measures demanded by Brussels in the face of the Eurozone’s largest deficit.
Political and Social Backlash
Lecornu's resignation triggered an immediate wave of reactions across the French political establishment. Socialist leader Olivier Faure claimed that Macron's bloc was disintegrating and that the government had lost legitimacy.
Key opposition figures, including Marine Le Pen and Jean-Luc Mélenchon, called for the dissolution of the National Assembly and even suggested impeaching the President. Jordan Bardella of the right-wing National Rally openly stated that restoring stability is only possible through early parliamentary elections.
Financial Markets React Sharply
The Prime Minister's departure immediately hit the French capital market. The CAC 40 index fell by as much as 2% today, with banking stocks suffering the most. The euro also depreciated to $1.1650.
French bond yields spiked, with the spread relative to German Bunds widening to 86 basis points (bps)—its highest level since the turn of December and January. Economists are increasingly warning that the political upheaval will further complicate budget negotiations, potentially causing the deficit to grow faster than projected.

Future Outlook
The government faces a deadline of October 13th to present the full draft of the budget bill. This latest prime ministerial resignation deepens the political crisis, making the scenario of early parliamentary elections an increasingly frequent topic in political commentary and market analysis.
For the coming weeks, the lack of a clear political direction and investor confidence will be the most significant factor determining France's economic and political future.
The situation is also spilling over into the wider European context, reflected by the EURUSD pair. The pair tested the $1.1650 vicinity today, its lowest level since September 25th. Should this crucial support level be breached, the pair could head toward its late August lows, further increasing pressure on the European Central Bank (ECB) to consider renewed interest rate cuts. At present, the market prices only a few percentage points chance of an ECB rate cut by the end of the year, and no more than a 30% probability of a cut within the currently forecasted horizon.
