The euro fell to its weakest level against the US dollar since May 2025 on Monday, as renewed concerns over French public finances and political uncertainty in Spain unsettled financial markets. The move has revived debate about debt pressures across the eurozone, although officials and analysts have stressed that current conditions do not yet replicate the sovereign debt crisis of 2008 or 2011.
The currency touched $1.1161 in Asian trading before recovering slightly to around $1.12 at the European open. It marked the euro’s fourth consecutive weekly decline, with investors also watching government bond spreads, inflation and the European Central Bank’s response to market stress.
French debt concerns weigh on the euro
France has been at the centre of the latest market anxiety. The spread between French and German 10-year bond yields reached about 146 basis points, following its largest weekly increase in 17 years, according to LSEG data.
France’s 10-year borrowing cost climbed to 4.917% early on Monday, close to a 24-year high, after ending the previous week at approximately 4.856%. A wider spread generally indicates that investors demand a higher premium to hold French debt compared with German government bonds, which are often treated as a benchmark for the eurozone.
French Finance Minister Roland Lescure has defended the country’s creditworthiness while presenting a 2027 budget designed to reduce the deficit from 5.4% of gross domestic product to 5%. The fiscal debate comes ahead of France’s presidential election next spring, adding a political dimension to concerns about deficit reduction.
Analysts at ING have warned that the euro could face a further risk premium if the bond sell-off continues. Such a development would increase borrowing costs for governments and could make it more difficult for highly indebted countries to reassure investors.
Spain’s snap election adds political uncertainty
Spain also contributed to the market’s cautious mood after Prime Minister Pedro Sánchez called a snap general election for 29 November. The announcement followed parliament’s rejection of two housing decrees backed by the minority government.
Spanish government bonds initially remained relatively stable. The 10-year yield traded between 4.07% and 4.09% on Monday morning, while the premium over German debt stood at roughly 65 basis points. That gap was less than half France’s spread, suggesting that investors currently view Spain’s market risk as more limited.
Nevertheless, the election introduces uncertainty over Spain’s fiscal and economic policy. Investors will be assessing whether the next government can secure parliamentary support for budgets and reforms, particularly at a time when eurozone markets are already sensitive to political developments.
Markets react across Europe
European shares opened unevenly as traders weighed the currency decline against wider global market movements:
- The Euro Stoxx 50 fell 0.4%.
- The broader Stoxx 600 rose 0.6%.
- France’s CAC 40 dropped by more than 1%.
- Spain’s IBEX 35 was about 0.4% higher after initially moving lower following the election announcement.
- Germany’s DAX, Italy’s FTSE MIB, the UK’s FTSE 100 and the Netherlands’ AEX posted modest gains.
Bond market pressure has not been limited to France and Spain. Italian, Belgian and Greek debt also came under pressure last week, while German bonds attracted demand from investors seeking relative safety. Italy’s premium over German debt approached 110 basis points on Thursday.
Why the ECB is being closely watched
The market turmoil presents a challenge for the European Central Bank. Inflation reached 3.8% in September, and the ECB has raised interest rates twice since June to contain price pressures. However, traders have reduced expectations of further increases as concerns about economic and financial stability grow.
The ECB’s Transmission Protection Instrument, created in 2022, remains an available bond-market backstop but has never been used. The tool is intended to address unwarranted and disorderly market dynamics, subject to conditions set by the central bank.
Joachim Nagel, president of Germany’s Bundesbank, said the ECB’s focus was price stability rather than targeting specific bond spreads. ECB President Christine Lagarde has described France’s debt trajectory as a serious issue, while also saying that the situation is not comparable with the crises of 2008 or 2011.
That distinction is important. A weaker euro and rising bond yields do not automatically amount to a new eurozone debt crisis. The immediate concern is whether higher borrowing costs spread further across member states and begin to affect financing conditions for households, businesses and governments.
What the euro’s decline means for Ireland
Ireland, as a eurozone member, is directly exposed to changes in the single currency and European interest-rate policy. A weaker euro can make imports priced in US dollars more expensive, including some energy, commodities and technology products. Its effect on exporters depends on the currencies used by their customers and suppliers.
Irish borrowers are also affected indirectly by ECB decisions. The central bank does not set retail mortgage rates, but its policy influences funding conditions for commercial banks. Any shift in expectations about interest rates may therefore affect borrowing costs, savings returns and business investment over time.
Ireland’s government bond market is not the same as France’s or Spain’s, and the source material does not indicate a comparable deterioration in Irish spreads. The broader issue for Ireland is the health of eurozone financial markets and the policy choices made by the ECB and national governments.
What happens next?
Investors will continue to monitor several developments:
- France’s progress in reducing its budget deficit and securing support for its fiscal plans.
- Spain’s election campaign and the prospects for a stable government after the 29 November vote.
- Bond spreads in Italy, Belgium, Greece and other eurozone economies.
- Inflation data and future ECB interest-rate decisions.
- Whether the euro can recover after four consecutive weekly declines.
US monetary policy will also remain relevant. American stocks rose after weaker-than-expected September jobs data reduced expectations of a Federal Reserve rate increase in October. Minutes from the Fed’s September meeting were due later in the week, offering further clues about the direction of US rates and the dollar.
Conclusion
The euro’s 17-month low reflects a combination of French debt concerns, Spain’s snap election and renewed worries about contagion in eurozone bond markets. For now, the pressure remains a market warning rather than evidence of a repeat sovereign debt crisis. The key test will be whether governments can contain borrowing costs while the European Central Bank balances inflation control against financial stability.
