The euro dropped to $1.12 on Monday, a 17-month low and a 5% decline since January, driven by a convergence of rising US bond yields, surging energy prices, and — most acutely — a sell-off in French government debt. French 10-year bonds touched 5% yields last week, and the spread between French and German debt hit levels unseen since the eurozone debt crisis of the early 2010s. This is not yet 2012, but the structural ingredients are uncomfortably familiar. France's fiscal deterioration is not sudden. Since Emmanuel Macron took office in 2017, public spending climbed while taxes were cut — a politically pleasant combination that added over €1 trillion in national debt. The debt-to-GDP ratio now sits at nearly 118%, and annual deficits regularly exceed 5%, up from 3.4% when Macron began. The budgets get passed, barely, but the trajectory is unmistakable: France is spending beyond its means and borrowing the difference at increasingly punishing rates. The bond market is now doing what bond markets do when they lose confidence: demanding a risk premium. Investors are rotating out of French debt into German bunds, widening the spread that serves as the eurozone's unofficial stress gauge. Italy, whose debt dynamics are even worse on paper, is catching contagion. The pattern — fiscal stress in a major eurozone economy triggering capital flight to Germany — is the exact mechanism that nearly broke the bloc a decade ago. The ECB is trapped in a policy corridor with no clean exits. Raising rates further, as inflation projections demand, would push French borrowing costs higher and accelerate the debt spiral. Signaling dovishness would weaken the euro further, amplifying imported inflation from dollar-denominated oil and gas. Oxford Economics' Ricardo Amaro describes this as threading a needle: the ECB must sound neither too hawkish nor too accommodative, a posture that works only as long as markets grant it time. Political risk is compounding the fiscal math. Marine Le Pen's National Rally is well-positioned for the 2027 presidential election, and investors are pricing in policy uncertainty. Spain's Pedro Sánchez just called snap elections after housing reform collapsed. Germany's AfD is reshaping expectations about the bloc's anchor economy. Cost-of-living anger is the common accelerant across all three — and a weaker euro makes the cost-of-living problem worse by raising import prices. The feedback loop is the story: fiscal weakness depresses the currency, a weak currency raises import costs, higher costs fuel inflation, inflation demands tighter monetary policy, tighter policy raises borrowing costs for indebted governments, higher borrowing costs deepen fiscal weakness. This is the doom loop that nearly destroyed the eurozone in 2012. The tools are better now — the ECB's Transmission Protection Instrument exists specifically for this scenario — but the political will to deploy them for France, the bloc's second-largest economy, would test every assumption about European solidarity. BNY's Geoffrey Yu says comparisons to 2012 are overblown. Maybe. But the difference between a crisis and a near-miss is often just timing and confidence. France's fiscal trajectory is unsustainable at 5% borrowing costs. Either the math changes — through growth, austerity, or restructuring — or the market forces a reckoning. The ECB can buy time, but it cannot fix a structural deficit.
