French draft budget caps spending growth to satisfy EU despite rising debt burden

France projects debt-to-GDP will rise to 121.7% in 2027 from 119.3% this year, despite a draft budget designed to keep net primary-expenditure growth at 0.7%, below the EU's 1.2% ceiling. The government also expects to miss its 2026 deficit target, with the deficit widening to 5.4% of GDP versus a 5.0% goal, and plans €54 billion ($62 billion) of spending curbs for 2027. French 10-year yields have climbed above 4.5% and the OAT-Bund spread has exceeded 100bps amid fiscal slippage and uncertainty over whether the minority government can pass austerity measures.

Analysis

The key transmission is not the headline debt ratio but the fiscal-arithmetic trap: higher OAT yields mechanically raise interest expense faster than modest expenditure restraint can offset it. A widening OAT-Bund spread therefore risks becoming self-reinforcing over the next 1-3 months, as weaker growth reduces tax receipts, implementation risk delays consolidation, and investors demand still more term premium. The most exposed equities are domestically oriented French financials, utilities and concessionaires with large home-market regulatory exposure; exporters with dollar revenues are relatively insulated.

French banks face a two-sided risk that consensus may underprice. Higher sovereign yields initially support asset yields, but a sustained spread shock raises mark-to-market pressure on government-bond holdings, funding costs, corporate defaults and political risk around windfall taxes or retail-rate intervention. BNP Paribas (BNP.PA), Crédit Agricole (ACA.PA) and Société Générale (GLE.PA) should underperform diversified European peers if the OAT-Bund spread remains above 100 bp through the budget vote; Italian-bank exposure is not a clean hedge because it adds correlated sovereign-beta rather than reducing it.

The contrarian case is that the market has already priced a substantial political premium, and any credible cross-party passage or EU-endorsed adjustment path could compress the spread sharply within days. That makes outright French-equity shorts less attractive after an initial selloff than a relative sovereign trade with defined stop-losses. The 6-18 month risk remains asymmetric: failure to legislate durable measures could trigger ratings pressure, force more aggressive fiscal tightening, and weaken French domestic demand precisely as refinancing needs rise.

Key Decisions for Investors

• Initiate/maintain a 1-3 month long German Bund versus short French OAT spread position; target a further 20-30 bp widening if the formal bill lacks enacted measures, with a stop on a sustained move below 85 bp after parliamentary support or a constructive ratings action.
• Pair trade: short BNP.PA and ACA.PA versus long UBSG.SW or SAN.MC over the budget-negotiation period. Use a 5-7% relative stop; the thesis is falsified if French banks demonstrate limited OAT-duration exposure and maintain 2027 net-interest-income guidance despite spread widening.
• For liquid equity implementation, underweight EWQ versus FEZ for 1-3 months rather than taking broad eurozone risk. Reassess immediately if the budget gains a durable legislative coalition, since spread compression would likely drive a sharp French beta reversal.
• Monitor the next sovereign-rating reviews and French bank disclosures for OAT carry, OCI sensitivity and deposit-beta trends. A downgrade, negative outlook, or renewed spread move above 120 bp would justify increasing the sovereign-relative hedge; absent those signals, avoid chasing a crowded outright short.
