The euro traded at $1.1174 at 7:44 a.m. ET on Thursday, October 8, down 0.2% on the day and 13 pips above Monday’s low of 1.1161, the weakest level since May 2025. The pair opened the session at 1.1196, managed an early high of 1.1204 and was at 1.1195 in early European dealing before sellers returned as French bond spreads widened again. The rose 0.2% to 102.40, within 14 points of the 18-month high it set at 102.54 on Monday.
The damage over the past month is substantial for a major currency pair. has fallen 3.6% since September 8, from a high of 1.1654 on September 9 to Monday’s 1.1161 trough, a slide of 493 pips. It is 7.5% below its 52-week high of 1.2079. In the third week of August the pair was changing hands near 1.1700.
Three forces are pressing on the single currency at once. The first is the bond market inside the euro area: the gap between French and German 10-year yields closed Wednesday at 134.4 basis points, up 7 on the day, and widened a further 5 basis points on Thursday morning. The second is energy. jumped 4.89% to $105.10 a barrel after President Trump said he does not want a deal with Iran, and the euro area imports nearly all of its oil. The third is the rate gap. The touched 5.35% while the sits at 3.49%, a 186-basis-point advantage for the dollar.
Against that, the pair is deeply oversold. The 14-day relative strength index is at 23 and was near 19 at Monday’s low. Readings that extreme have slowed the decline, which is why the euro has spent four sessions oscillating between 1.1161 and 1.1277 instead of extending lower. They have not produced a reversal.
Thursday’s calendar adds two inputs. The European Central Bank published the account of its September 9–10 meeting, at which it raised rates by 25 basis points. US initial jobless claims came in at 197,000, under the 200,000 forecast. Neither changes the picture: the euro’s problem this month is domestic credit risk and imported inflation, and the dollar is collecting the flows.
From 1.1654 to 1.1161: A One-Month Breakdown in Four Legs
The slide came in distinct steps, each tied to an event. On September 9 the pair peaked at 1.1654 and closed at 1.1633. The ECB raised rates the next day, and the euro fell anyway, closing at 1.1612. A central bank hiking into a currency that weakens on the decision is a sign that the market is focused on something other than the policy rate. By September 14 the pair was at 1.1549 after a 0.44% drop.
The second leg arrived with the Federal Reserve. On September 16 the Fed lifted its target range to 3.75% to 4.00%, and EUR/USD fell 0.68% from 1.1539 to 1.1466. It held between 1.1453 and 1.1498 for four sessions, then lost another 0.59% on September 23 to close at 1.1382. That move broke the pair below 1.1400 and coincided with French 10-year yields pushing above 4.5% for the first time since 2008.
The third leg was the sharpest. After drifting from 1.1391 to 1.1330 across the last week of September, the euro dropped 0.78% on October 1, from 1.1330 to 1.1242, with a low at 1.1215. That session took the pair through 1.1300 for the first time since May 2025 and through the 1.1362 level that had formed a triple bottom on the daily chart. Euro area inflation data the next morning showed a jump to 3.8%, and French spreads recorded their largest weekly widening in 17 years.
The fourth leg has been a volatile base. On Friday, October 2, a weak US payrolls report lifted the pair to 1.1286 before it closed at 1.1254. On Monday, October 5, news that Spain would hold a snap election sent it to 1.1161 before a recovery to 1.1223. Tuesday brought a 0.33% gain to 1.1260, with a high of 1.1277, as Brent slipped below $98 and French yields eased. Wednesday erased it: the pair fell 0.53% from 1.1260 to 1.1200, with a low of 1.1165, as oil and yields turned higher and the Fed minutes landed.
Thursday’s trade at 1.1174 puts the euro back at the bottom of that four-day range. Lower highs at 1.1286, 1.1277 and 1.1267, against a flat floor at 1.1161 to 1.1165, form a descending triangle. That pattern more often resolves in the direction of the prior trend.
France’s 134-Basis-Point Spread: The Euro’s Home-Grown Risk Premium
The single largest driver of the euro’s decline is the French government bond market. On September 8 the yielded 4.24% and the German Bund 3.39%, a spread of 85.3 basis points. On October 7 the OAT yielded 4.83% and the Bund 3.49%, a spread of 134.4 basis points. French borrowing costs rose 59 basis points in a month while German costs rose 10.
The peak came on Friday, October 2, when the spread touched 159 basis points intraday, the widest since the 2012 euro crisis. It stood at 147 on Monday, narrowed to 127.4 on Tuesday as oil fell, and widened by 7 on Wednesday and another 5 on Thursday. France’s 10-year yield reached 4.917% on Monday, close to a 24-year high.
The fundamentals behind the move are fiscal and political. The French finance ministry projects public debt at a record 119.3% of GDP. The government filed its 2027 budget on October 6 into a fragmented parliament that has toppled successive administrations over the same exercise, and the National Assembly takes it up on October 13. A sovereign rating review is scheduled for October 23. A national election looms next year.
For the currency, the mechanism is direct. When investors sell French debt and buy German debt, the money stays in euros. When they sell French debt and buy Treasuries yielding 5.35%, it leaves. The widening spread also tightens financial conditions across the bloc, because French yields are a reference for corporate and bank funding costs in the euro area’s second-largest economy. A wider spread functions as a rate hike the ECB did not choose, concentrated in one country.
What makes this episode different from 2011 is the source. France is a core issuer. Italy and Spain are trading as followers, with their spreads moving in sympathy. The ECB’s backstop, the Transmission Protection Instrument created in 2022, has never been used, and it was designed for disorderly moves unrelated to fundamentals. Widening driven by a budget impasse and a rising debt ratio is harder to label unwarranted.
The euro has tracked the spread almost tick for tick. The pair’s low on October 5 came with the spread at 147. Tuesday’s bounce to 1.1277 came as it narrowed to 127.4. Wednesday’s drop to 1.1165 came as it widened to 134.4.
Spain’s Snap Election and the ECB’s Backstop Dilemma
Political risk is spreading beyond Paris. Spanish Prime Minister Pedro Sánchez called a general election for November 29 after parliament rejected his housing plan and protests over housing costs intensified. The announcement on Monday coincided with the euro’s 17-month low at 1.1161.
The market reaction in Spanish bonds was contained. Snap elections in Spain have historically produced modest moves when the outcome was signaled by polling, with larger concessions reserved for surprise coalition results. The euro actually bounced after Sánchez confirmed the date, because the reports that preceded the confirmation had done most of the damage. The pair closed Monday at 1.1223, 62 pips off the low.
The broader issue is accumulation. France has a budget fight and an election next year. Spain votes in seven weeks. Spanish inflation ran at 4.9% in September, more than a full point above the euro area’s 3.8%, which sharpens the political cost of each ECB rate increase in Madrid. Two of the bloc’s four largest economies face electoral uncertainty while the central bank is tightening.
That leaves the ECB with conflicting jobs. It has to sound firm on inflation to keep expectations anchored with headline price growth nearly double its 2% target. It is also expected to step in if the French selloff turns disorderly. Buying French bonds while raising rates would be a difficult message to deliver, and the Governing Council has shown no sign it wants to try. As long as the widening is orderly and tied to fiscal news, the central bank is likely to tolerate it.
For EUR/USD, that tolerance is the problem. A currency whose central bank is hiking would normally draw support from higher rates. The euro is not getting that support because every hike raises the cost of servicing French and Italian debt and pushes spreads wider. The market has started to treat ECB tightening as a threat to the bloc’s stability, which inverts the usual link between rates and the exchange rate.
The dates that matter are close together. The French Assembly debate begins October 13. The rating review falls on October 23. The ECB meets October 29. Spain votes November 29. A positive surprise on any of the first three, such as a budget compromise or an affirmed rating, would narrow the spread and give the euro room to recover toward 1.1362. A failed budget vote or a downgrade would test 1.1161 immediately.
Brent at $105: Europe Pays the Oil Bill
The second pillar of euro weakness is energy. Brent crude rose 4.89% to $105.10 a barrel on Thursday and gained 5.15% to $92.83 after Trump told a rally that a deal with Iran “isn’t really something that I want to do” and reports indicated the Pentagon is preparing for renewed large-scale strikes. Tanker attacks in the Strait of Hormuz last week were the highest of any week since the war began on February 28.
Oil has been the cleanest daily predictor of the pair this month. On Tuesday, Brent fell below $98 as Gulf exports picked up, and EUR/USD rose 0.33% to 1.1260. On Wednesday, Brent climbed back above $100 and the pair fell 0.53%. On Thursday, Brent hit $105 and the euro slipped toward 1.1174. The dollar index has been moving with crude and the euro more closely than with expectations for the Fed’s next meeting.
The reason is terms of trade. The United States is a net exporter of crude and refined products, so higher prices improve its trade balance. The euro area produces almost no oil. Every dollar on the Brent price transfers income from European consumers and firms to producers abroad, and the bill is paid in dollars. Japan faces the same squeeze. Together, energy importers make up more than 70% of the basket the dollar index measures against.
The inflation data shows the pass-through. Euro area energy inflation ran at 18.8% in September, up from 14.3% in August. Producer prices were 8.2% higher than a year earlier. Benchmark diesel futures jumped 4.5% in European trading on Thursday. The ECB’s chief economist said this week that costlier energy and higher long-term borrowing costs are already slowing demand in the bloc.
That combination, rising prices with falling demand, is the worst mix for a currency. It squeezes real incomes, weakens the trade balance and leaves the central bank choosing between inflation and growth. The US faces higher inflation from the same shock but with a labor market still posting jobless claims under 200,000 and an economy that earns export revenue from the commodity in question.
The offset would be a diplomatic turn. Oil fell 10% to 11% in a single session earlier this year when strikes were postponed, and the euro rallied with it. A headline of that kind would be worth 100 pips or more to EUR/USD within hours. Absent one, the market is pricing Brent above $100 through the fourth quarter, and at that level Europe’s energy import bill keeps the pair heavy.
The 186-Basis-Point Yield Gap: Why Capital Is Crossing the Atlantic
Rate differentials are the third pillar. The US 10-year Treasury yield touched 5.35% on Thursday, its highest since April 2002, before settling near 5.30%. The German 10-year Bund yields 3.49%. At the peak, the gap was 186 basis points in the dollar’s favor. The yields 5.70% and the 4.812%.
For a European investor, that spread is the incentive. Buying a 10-year Treasury instead of a Bund earns an extra 1.86 percentage points a year, and getting it requires selling euros and buying dollars first. The flow is mechanical, and it grows as the gap widens.
The composition of this week’s move matters. German yields have been held down by safe-haven demand from investors leaving French debt. On Wednesday, with the OAT-Bund spread widening 7 basis points, money rotated into Bunds and kept the 10-year near 3.5% even as Treasury yields set new highs. So the French problem hurts the euro twice: once through the credit premium, and again by suppressing the German yield that would otherwise narrow the transatlantic gap.
Policy rates tell the same story at the front end. The Fed’s target range is 3.75% to 4.00%. The ECB’s deposit rate is 2.50%. The 125-to-150-basis-point gap in overnight rates makes it expensive to be short dollars and cheap to be short euros. Both central banks are hiking, but the Fed started from a higher level and markets price more to come: futures imply a 70% chance of another Fed increase by December and further tightening into 2027.
Real rates are more lopsided still. With euro area inflation at 3.8% and the deposit rate at 2.50%, the ECB’s policy rate is 1.3 percentage points below inflation. The euro is a negative-real-yield currency at the short end while the 10-year US inflation-protected yield sits near 2.91%.
There is one way the gap narrows quickly. If the US Treasury’s $22 billion 30-year auction at 1:00 p.m. ET on Thursday draws strong demand, as Wednesday’s $39 billion 10-year sale did, Treasury yields could ease as they did late Wednesday when the 10-year fell to 5.279%. A softer US CPI print on October 14 would do more. Each 10 basis points off the spread has been worth roughly 30 to 40 pips to the pair during this move.
