• Euro tumbles 0.73% to $1.1178, its weakest level since May 2025, as French fiscal jitters and soaring global bond yields fuel a broad dollar rally.
  • Sterling drops 0.55% to $1.3205, with traders attributing the sell-off to rising U.S. Treasury yields and safe-haven demand.
  • Market watchers warn that sustained rate volatility could keep pressure on European currencies, though a modest rebound followed the initial headline.

Dollar Surges on Safe-Haven Demand

The euro and pound both fell sharply against the dollar on Monday, as a sell-off in European bonds and concerns over France's fiscal outlook sent investors scrambling for safer assets. The euro touched $1.1178, down 0.73% on the day, while sterling slid 0.55% to $1.3205.

The euro's slide marked its weakest level since May 2025, extending a four-week losing streak. The immediate trigger, according to traders, was a steep sell-off in French government bonds amid worries about the country's debt burden and political gridlock ahead of the 2027 election. The stress in French debt markets rippled across the euro area, heightening demand for the U.S. dollar as a safe haven.

"The combination of higher Treasury yields and the global debt sell-off has made the dollar the default hiding place," said Matthew Ryan, head of market strategy at Ebury. "It's not so much that Europe has suddenly become uninvestable, but the U.S. is offering a better return for the same risk."

Bond Rout Adds Fuel to Currency Moves

The currency moves came amid a broader rout in global bonds that pushed borrowing costs to multi-decade highs. The U.S. 10-year Treasury yield stood at 5.262% in Monday's trade, making dollar-denominated assets more attractive. Rising oil prices added to inflation worries, further complicating the picture for central banks.

Sterling's decline was less severe but still notable, with the pound slipping to $1.3205. The currency had been relatively resilient in recent weeks, supported by expectations that the Bank of England would keep rates higher for longer. But the global bond rout has forced investors to reassess.

According to Reuters (TRI), the euro's drop to $1.1178 was its lowest since May 2025, and the selling pressure was broad-based. The single currency also weakened against the Swiss franc, another traditional safe haven, underscoring the depth of risk aversion.

French Budget Wrangling in Focus

While the headline numbers reflect the latest market snapshot, the underlying story is one of fiscal credibility. France's budget discussions have been fraught, with investors questioning whether the government can deliver on promised deficit reductions. Spectra Markets' Brent Donnelly noted that fiscal promises ahead of a possible political transition may lack credibility, adding to the euro's vulnerability.

"The market is essentially asking France to prove it can get its house in order," Donnelly wrote in a note to clients. "Until that happens, the euro will struggle to shake off this risk premium."

Meanwhile, shifting expectations for Federal Reserve policy also played a role. Weaker-than-expected September U.S. job growth reduced the odds of an immediate rate hike. On Monday, market-implied probability of unchanged October rates stood at 78%, up from 36% a week earlier, according to Reuters. That repricing gave the dollar a further boost, as traders trimmed bets on aggressive Fed tightening.

The euro's decline was not uniform across all sessions. By Tuesday, the ECB's official reference rate had recovered to $1.1269, indicating a partial bounce. Sterling also firmed, trading at $1.3247, up 0.20% from Monday's close, as bond yields and oil prices retreated. European equities rebounded, suggesting a broader improvement in risk appetite.

Outlook Hinges on Fiscal Credibility and Rate Paths

Looking ahead, analysts say the key variables are French borrowing costs, upcoming budget developments, oil prices, and central bank expectations. OCBC (O39.SI) strategists warned that sustained rate volatility could keep pressure on the euro and cyclical currencies while supporting the dollar and Swiss franc.

Not everyone expects further aggressive tightening. Bank of Singapore's Mansoor Mohi-uddin expects the Fed to leave rates unchanged in October. Jefferies (JEF) strategist Mohit Kumar sees one hike each from the Fed and ECB—less than markets are pricing—arguing that either lower oil prices or weaker growth could limit the need for additional increases.

"We're at a point where the market is pricing a lot of tightening, but the data doesn't necessarily support it," Kumar said. "If oil comes off or growth slows, the ECB and Fed may not need to move as much."

For households and businesses, the weaker euro and pound mean higher costs for dollar-priced imports and travel to the United States. Exporters and tourism businesses, however, could benefit as dollar-paying customers gain purchasing power. Importers and dollar borrowers face more expensive debt servicing, while governments and investors contend with rising sovereign yields and currency volatility.

The euro's rebound on Tuesday serves as a reminder that the headline figure is a snapshot, not a settled trend. With French fiscal uncertainty unresolved and global bond markets still jittery, further swings are likely. As one strategist put it, "This is a market that's looking for direction, and until France shows a credible path, the euro will remain on the back foot."
