France unrest triggers euro contagion

Social breakdown and protests in a large, highly‑indebted eurozone economy (France) can push its 10‑year bond yields above a political threshold, initiating a fiscal 'doom loop' that spreads to neighbouring indebted countries (Belgium, Italy) via higher borrowing costs and market runs. That financial contagion may then feed back into politics — forcing austerity or fragmentation within the eurozone and producing knock‑on effects for nearby economies such as the UK. — If credible, the idea reframes recent protests as not merely domestic politics but as a plausible trigger of a systemic eurozone debt crisis with cross‑border economic and political consequences.
