The euro fell as low as $1.1161 on Monday, a 17-month low and its weakest level since May 2025, Reuters reported. The trigger was France: fiscal worries after a steep rout in French bonds, plus political gridlock ahead of next year’s election. The slide was strong enough that the dollar shrugged off soft US jobs data that would normally have weighed on it.

The bond numbers are sharper than the currency headline. The premium France pays over Germany to borrow for 10 years ended last week at 140 basis points, after a 34-point jump that was the biggest weekly widening in 17 years, according to LSEG data cited by Reuters. On Monday, German Bund futures rose while French bond futures hugged record lows. DW reported that French 10-year yields touched 5% last week before easing slightly, and that the France–Germany gap reached its widest since the eurozone debt crisis.

Budget math meets election math

Prime Minister Sébastien Lecornu presented a belt-tightening 2027 budget on Oct. 1. It aims to cut the deficit to 5% of output next year from a 5.4% target this year, France 24 reported, with €43 billion in “recovery measures” that would bring the “total effort” to €54 billion if passed, according to a plan seen by AFP. Reuters reported the squeeze includes freezing public-sector wages and all but the lowest pensions. France’s independent fiscal watchdog, the High Council for the Public Finances, called the 2027 deficit cut “limited,” said a “significant” effort was still needed to stabilise debt, and called the government’s 1% growth forecast “optimistic.”

The debt is already heavy. The INSEE statistics office put it at a post-World War II record of 119% of output as of the second quarter, and France is set to sell a record €340 billion of debt next year to cover the shortfall and refinance cheap pandemic-era bonds now coming due. Economy Minister Roland Lescure has said every tool is available to pass the budget, including article 49.3, which lets the government adopt it without a parliamentary vote, according to France in English’s summary of French reporting. “5% is 5%. It’s not 5.1, it’s not 5.2,” he said. The presidential vote is set for April 18 to May 2, 2027, with far-right leader Marine Le Pen far ahead in the polls, per France 24.

That timing is the problem for markets. “Any budget promises made by the French government now are not super credible with a change of power coming soon,” Spectra Markets’ Brent Donnelly told Reuters.

Contagion, or a France story?

Analysts are split. Pepperstone’s Chris Weston saw “possibly a whiff of contagion creeping in.” State Street’s Ninghui Liu said, “For now, I think it’s more of a country story rather than the euro crisis.” Deutsche Bank’s Jim Reid wrote that the spread had at one point last week become wide enough for a “mini-panic,” and asked “whether this is the start of a new euro sovereign crisis or whether markets have already overshot,” DW reported. BNY’s Geoffrey Yu told DW that “comparisons to 2012 are well off the mark.” These are competing reads, not settled fact.

What it means for you

A weaker euro makes dollar-priced imports, including oil and gas, cost more for Europeans. Oxford Economics’ Ricardo Amaro told DW that “sharper euro weakness would reinforce the inflationary shock at a time when inflation is already expected to stay high into 2027.” Higher French borrowing costs also raise what Paris pays to roll over its debt, which feeds straight into the tax and spending fight before any ballot.

If you live in the eurozone, watch import prices and energy bills more than the drama in Paris: the currency is how this reaches you. If you are outside Europe, the same move cuts the other way. European goods get cheaper for you, but euro-denominated savings or investments are worth less in dollars. DW noted that the pressure has already spread to other government bond markets, including Italy’s, which is the place to look first if contagion is real.

Signal to watch: the France–Germany 10-year spread around 140 basis points, whether the euro holds near $1.12 or breaks lower, and whether Paris forces the budget through with 49.3 or passes a credible 5% deficit path by vote. If spreads keep widening into the April–May election window, markets are likely pricing French politics as fiscal risk. If the budget lands and the premium compresses, Monday’s euro low likely proves a scare rather than the start of a crisis.
