France's Borrowing Cost Gap With Germany Hit About 147 Basis Points on October 5, the Widest Since the Euro Crisis, Ahead of a Moody's Review on October 23

The cost of lending to France has moved sharply higher relative to Germany, and the next two weeks contain several dates that could move it again. The measure is the OAT-Bund spread: the difference between the yield on France's 10-year government bond, the OAT, and the yield on Germany's 10-year Bund, which is the euro area's benchmark safe asset. According to a Babypips explainer dated October 12, 2026, the spread reached about 147 basis points on October 5, the widest since the euro debt crisis of 2011 and 2012, and by October 9 it was around 130 to 140 basis points. A basis point is one hundredth of a percentage point, so 147 basis points is 1.47 percentage points of extra yield. This article relies mainly on Babypips, with background from French financial press. The explainer does not give an exact current reading or absolute yield levels, and it contains a date inconsistency that we flag below.

What is normal? Babypips says a calm-market range is roughly 20 to 50 basis points, and that the spread was about 55 in February 2026. So the gap has more than doubled in eight months. The explainer states that at the October 5 peak France's spread was wider than those of Italy and Greece, two countries that were at the centre of the earlier crisis. Other publications in our search results point to the same direction of travel. Option Finance and ABC Bourse have published pieces on the OAT-Bund spread and market concern over French debt, and GlobalCapital has written about French political turmoil straining the spread, though we have not reviewed those articles in full.

Why has it widened? The explainer lists several reasons. Government debt is about 119% of gross domestic product, against a European Union reference value of 60%. The deficit for 2026 is projected near 5.4% of GDP, above the EU's 3% ceiling, and the 2027 budget aims to bring it to 5%. The politics are a second factor. Babypips says no party has held a stable majority in the National Assembly since President Emmanuel Macron called snap legislative elections in June 2024, and it counts four prime ministers since then. It says Francois Bayrou lost a confidence vote in September 2025 and was replaced by Sebastien Lecornu, who resigned after 27 days and then returned. The explainer dates that return to October 10, 2025, which conflicts with the article's 2026 setting, so the exact date may be an error. We cite the sequence of events only as the explainer gives it.

What is coming? The article lists four dates. The National Assembly's budget debate began on October 13. A vote on the first part of the 2027 budget is set for October 20. Moody's is scheduled to review France's sovereign credit rating on October 23, although the explainer does not state the current rating or outlook, so we cannot say what a change would mean. The separate vote on the 2027 social security budget is due on October 27. The article also mentions a possible confidence vote on a Thursday without giving the date. Any of these could move the spread. A budget that passes with credible deficit cuts could ease pressure, and a failed vote or a rating action could add to it.

How should the numbers be read? The explainer offers thresholds rather than forecasts. A spread above 120 basis points is no longer a new warning. A sustained move below 120 could mean that pressure is easing, a rise toward 150 could renew it, and a move toward 70 to 80 would be a more meaningful improvement in sentiment. These are one publication's rules of thumb, not official benchmarks.

Does it matter outside France? Yes, for several reasons. Because France is in the euro, investors who are worried about it cannot sell a separate French currency, so some of the pressure can show up as weaker demand for the euro, the explainer says. Banks, insurers and pension funds hold large amounts of French government debt, and a rise in yields lowers the market value of the bonds they already own. The explainer does not discuss insurers or banks, so we do not quantify the effect. What can be said in general is that insurers hold government bonds to match long-term liabilities and are exposed to both price falls and to the higher yields that follow, which can help new investment returns. For savers and policyholders in France, the immediate effect is limited, because most life insurance and savings contracts are long term and are not valued daily at market prices.

For the French state, a wider spread means that every new bond it issues costs more to service, which makes the budget arithmetic harder. That is the link between the parliamentary calendar and the bond market. Readers should watch the October 20 vote, the October 23 Moody's decision and the October 27 social security vote, and should check the daily spread from a market data source.
