France is the hardest hit in the global bond sell-off, mostly due to its own fiscal and political weakness. Since the Hormuz crisis began, 10-year OAT yields have risen 150bps (US +115bps, Italy +132bps, Germany +83bps) as the prolonged energy crisis exacerbates fiscal concerns in a politically fragile environment. France’ fiscal deficits have remained above 5% of GDP for four consecutive years. Debt has risen from 98% of GDP in 2019 to over 119% in Q2 2026, and the 2026 deficit is now expected at -5.4% against a -5% initial target.
A "short Europe" trade amplifies the move and spreads it to the rest of the Eurozone while the ECB looks the other way. Foreign banks and non-banks hold 36% of OATs and Japanese investors about 5% (EUR137bn), exposing France to the repatriation trade and price sensitive investors. Speculative shorts, hedge-fund asset-swap unwinds and thin liquidity feed a negative loop, with market depth more than 50% below normal and the OAT spread over Bunds peaking at 150bps. The speed reflects a positioning shock, not a pure repricing of fundamentals. Long-term investors are sitting out ahead of the elections, given budget uncertainty and the sensitivity of OATs to political fragility. Spanish and Italian spreads are about 20bps wider, bank CDS are widening and French and Italian three-month bills are converging toward the ECB's marginal lending rate. Fragmentation is far from 2012 or 2020 levels, but the ingredients are in place. The ECB has not yet intervened and may limit itself to verbal intervention, while continuing QT and pushing through two more hikes (+50bps).
Baseline: A watered-down budget, but the fiscal arithmetic stays heavy for France. We expect GDP growth of +0.5% in 2026 and +0.9% in 2027. The Assembly votes on the budget on 20 and 27 October, and we expect a budget by year-end through ordinances or Article 49.3, keeping the 2027 deficit at -5.3% of GDP. This should contain fiscal slippage and stabilize financial conditions, with OAT spreads in the 120-150bps range. Higher rates (+100bps) will feed through over the next three to six months, adding EUR25bn (0.8% of GDP) in gross interest expenses for households, non-financial firms and the government combined. The debt stabilizing deficit is -2.7% of GDP, which requires savings of more than EUR80bn, plus EUR15 20bn a year to stop social and interest spending from widening the deficit. This takes credible fiscal measures (better tax mix, higher retirement age) and growth-enhancing reforms.
Adverse scenarios: France-centered crisis or Eurozone crisis? The Middle East situation is far from contained; oil prices could stay above USD100/bbl for another six months, leading to a further global bond sell-off hitting France the hardest, tightening financial conditions and jeopardizing deficit reduction. Domestically, opposition parties could take down the government or slippage surprises resurface despite a passed budget, tightening conditions in the same way. In this context, GDP would stall at +0.0% in 2027 and spreads reach 150-175bps. The ECB would talk up and potentially launch repo intervention. In our view, it would take a substantial Eurozone-wide contraction (France -0.5% in 2027; Eurozone -0.2%; OAT spreads at 175-200bps) for the ECB to tweak or stop QT, launch open market and repo intervention and stabilize funding markets (as OATs and BTPs make up 50% of euro repo collateral).
Looking ahead, the 2027 elections are the next test, and TPI is a late and uncertain backstop. With the presidential election on 18 April and 2 May 2027 (legislative elections likely to follow), we see four scenarios: i) a President with an absolute majority and allies, who delivers fiscal consolidation; ii) a President short of a majority who seeks alliances (our baseline, with the 2028 deficit at -4.9% and spreads above 100bps); iii) a President short of a majority without alliances and iv) a political and fiscal crisis, for instance from unfunded tax cuts or spending hikes, with spreads above 200bps and widespread contagion. Only in this last scenario would the ECB activate the Transmission Protection Instrument (TPI). The risk is a lack of political will rather than of instruments, and redenomination risk is the tail case.
