EUR/USD Near 17-Month Lows as French Fiscal Concerns Fuel Dollar Strength

Key Takeaways

• EUR/USD traded just below 1.12 on October 7, returning toward its lowest levels in almost 17 months as concerns over France’s public finances weighed on the euro.
• The US Dollar Index rose to around 102.40 during the session, approaching Monday’s peak near 102.50 and its strongest levels since April 2025.
• Higher US Treasury yields and reduced expectations for European Central Bank rate increases added to pressure on the single currency.

US Dollar Strengthens as EUR/USD Returns Toward 17-Month Lows

The US dollar strengthened on October 7 as renewed concerns over France’s fiscal position pressured the euro. EUR/USD fell approximately 0.6% to just below 1.12 during the session, bringing the currency pair back toward its recent lows. A close around that level would have been its weakest since May 16, 2025.

The ICE US Dollar Index climbed about 0.6% to 102.40 in a separate intraday snapshot. Rising Treasury yields and uncertainty in Europe supported the move, leaving the index close to its strongest closing levels since April 2025.

The renewed euro weakness followed a brief recovery earlier in the week. The currency’s difficulty sustaining that rebound suggests that concerns over European sovereign debt remain an important influence on trading, alongside expectations for US and eurozone interest rates.

French Fiscal Concerns Weigh on the Euro

France’s public finances have become a central concern for currency markets. Investors are questioning the government’s ability to control spending and reduce its budget deficit, with the resulting uncertainty contributing to selling pressure in French government bonds.

Benchmark French borrowing costs approached 5% during the recent sell-off, compared with around 3.2% in late February. EUR/USD briefly reached approximately 1.1160 on October 5 as the deterioration in the bond market intensified pressure on the single currency.

Higher sovereign yields can have different implications for a currency. When yields rise because investors expect stronger growth or tighter monetary policy, they may make local assets more attractive. When the increase reflects doubts about fiscal sustainability, the higher return can instead represent compensation for greater perceived risk.

That distinction matters for the euro. If investors become less comfortable holding French debt, the pressure can extend beyond government bonds into confidence in euro-denominated assets. Higher financing costs may also complicate efforts to improve the fiscal position, particularly if economic growth weakens.

Reduced ECB Rate-Hike Expectations Add Pressure

The euro also faced pressure as investors scaled back expectations for additional European Central Bank interest-rate increases. The combination of fiscal uncertainty and a less supportive expected policy path left the currency vulnerable against the dollar.

Currencies respond to changes in the expected difference between interest rates across economies. If markets anticipate less tightening in the eurozone while US borrowing costs remain elevated, the relative return available on dollar assets may become more attractive.

However, weaker expectations for ECB rate increases do not automatically mean that rate cuts are imminent. Market pricing can change as investors reassess inflation, economic activity and financial conditions. A shift in expectations should therefore be distinguished from an actual policy decision.

The challenge for the euro is that monetary policy and sovereign risk are interacting. More restrictive financial conditions could weigh on activity, while persistent inflation could limit the central bank’s room to respond. This leaves upcoming economic data and ECB communication important to the currency’s direction.

Treasury Yields Support the Dollar

Higher US Treasury yields provided another source of support for the dollar during October 7 trading. Alongside European fiscal concerns and geopolitical uncertainty, they helped keep the currency close to its recent highs.

The effect of higher yields depends partly on why they are rising. Expectations for tighter Federal Reserve policy can support the dollar by increasing anticipated returns on US assets. Changes in inflation expectations, government borrowing or bond-market risk premiums can produce a more complicated response.

Dollar strength and euro weakness also reinforce one another in the Dollar Index because the euro accounts for nearly 58% of its weighting. A sharp decline in EUR/USD can therefore lift DXY substantially, even when the dollar’s performance against other currencies is less uniform.

For that reason, the index’s advance should be assessed alongside individual currency pairs. A higher DXY reading alone does not establish that the dollar is gaining equally against the yen, sterling or other major currencies.

Earlier Rebound Shows Sensitivity to Bond-Market Developments

The week’s trading also demonstrated how quickly the euro can respond when pressure on French debt eases.

On October 6, EUR/USD recovered to around 1.1244 while French government bond yields fell. The Dollar Index slipped toward 102.00 after reaching approximately 102.535 on Monday.

That recovery was followed by renewed euro weakness on Wednesday. The sequence highlights the importance of distinguishing a short-lived improvement in sentiment from a sustained change in the underlying fiscal outlook.

A more durable recovery would likely require evidence that sovereign-debt concerns are easing, alongside a more favourable shift in relative interest-rate expectations. Conversely, renewed bond selling could keep the euro under pressure even if individual economic releases provide some support.
