France's widest bond spread since 2011 drags the euro to a 17-month low

"Latest bond market dynamics are increasingly concerning and somewhat reminiscent of a sovereign debt crisis. Friday's acceleration of the sell-off in OAT spreads and flight-to-quality patterns in Bunds are a case in point," Hauke Siemssen, a strategist at Commerzbank, said ^[5]. "The (French) spread sell-off seems to increasingly feed on itself, creating a dangerous market backdrop," he said, adding that there is a fundamental justification for wider OAT spreads ^[6].

Monday's prices fit the self-feeding description. At 145.50 the spread was 4.5bp under Friday's peak, and it had already retraced 5.5bp of its 10bp pullback to 140, a little over half ^[1]. The euro moved the same way. It hit $1.1161 in Asian hours, its weakest since May 2025, then kept falling and was last quoted 43 pips below that low, down 0.62% on the day ^[7][2].

The fundamental justification Siemssen mentions comes down to the budget. The cuts France has already planned have deepened an acute funding crunch in education and set off protests across the country ^[10]. I would not expect a government facing those protests to propose deeper cuts before the presidential election. French bonds were already under pressure from expectations of higher policy rates and from uncertainty about that vote ^[2].

The counter-thesis is that this is mostly a dollar move and France is just the headline. Traders still price a Fed hike in December and two more in the first half of 2027 ^[15]. The dollar index is about 1.6% short of the roughly 104 it held before the Liberation Day tariff package in April 2025, taking 104 less 102.33 and dividing by 104 ^[14][3]. A Fed that keeps hiking has room to push it the rest of the way without any help from Paris.

If Siemssen is right, the spread goes back through 150 and the euro makes new lows with it. If the spread settles between 140 and 150, the euro goes back to trading Fed expectations. A budget compromise would narrow the spread, though a hung parliament where compromise has often proved impossible makes that the least likely of the three ^[9]. I think the first is the likelier path, because the protests and the hung parliament both stand in the way of a deal that would ease the budget fight.

The thesis is wrong if the spread drifts back toward 140 while the euro keeps falling. That combination would mean the currency is trading the Fed. The report does not include positioning or flow data, so the portfolio case rests on prices alone.
