Why the Euro Remains Under Pressure Even as the ECB Hikes

#

Both the Federal Reserve and the European Central Bank raised rates by 25 basis points in September 2026, yet the euro remains stuck near 1.148 against the dollar, held down by forces no single rate decision can lift.

That anchoring reflects more than one problem. A stubborn 125-150 basis point policy gap favouring the dollar supplies the immediate mechanical pressure, but the Eurozone’s structural weaknesses are compounding the strain underneath it. Sluggish growth and sticky inflation are reviving stagflation fears, just as unexpected election outcomes in Germany and fiscal turbulence in France inject a fresh political risk premium into European assets.

The mechanical weight of the US and European policy gap

Both central banks moved in the same direction in September 2026, and both moved by the same amount. That is where the symmetry ends.

On 16 September 2026, the Federal Open Market Committee (FOMC) raised its target range by 25 basis points to 3.75%-4.00%, its first hike since 2023. Six days earlier, on 10 September 2026, the ECB Governing Council lifted its deposit facility by the same 25 basis points, but only to 2.50%. Identical actions, vastly different terminal ranges.

The result is a policy gap of roughly 125-150 basis points in favour of the dollar. That gap sustains a carry advantage, meaning investors earn a higher return simply for holding dollar-denominated assets rather than euro ones.

The market is voting accordingly. The US Dollar Index (DXY) has been operating just under the 100 level, and the benchmark 10-year US Treasury yield eased to 4.95% on 21 September 2026 after peaking at 5.04% in mid-September, its highest reading since 2007 according to Bloomberg.

Research from Erste Group and HSBC, which plots EUR/USD against the US-Germany 2-year yield differential, shows the relationship plainly: when the spread widens in favour of US yields, the euro weakens, and when it narrows, the euro recovers.

The persistence of this yield gap tells you that holding euro assets carries a definitive opportunity cost right now. central bank divergence moves currencies primarily through forward rate expectations rather than any single decision, which is why the September 2022 episode saw the euro fall more than 15% even as the ECB was itself hiking rates.

The persistence of this yield gap tells you that holding euro assets carries a definitive opportunity cost right now. You have to factor that structural disadvantage into any near-term currency view, because it explains why positive European data so often fails to spark a lasting euro rally while the Fed keeps rates higher for longer.

How energy dependency and stagflation structurally anchor the currency

Rate differentials explain the immediate pressure. They do not explain why the euro struggles to recover even when the yield story softens. For that, you have to look at the Eurozone’s underlying vulnerability to imported energy.

Stagflation describes an economy where inflation stays high while growth stalls, the two conditions central banks least want to see together. The 2026 Eurozone is edging toward exactly that combination. Eurostat data shows final Euro area HICP inflation accelerating to 3.2% in August 2026, back above the ECB’s 2% target, while Q2 2026 GDP grew a mere 0.6% quarter on quarter.

The stagflation threat the Eurozone faces in late 2026 is not abstract: Brent crude near $97 has already triggered a repricing across equity portfolios, with Barclays explicitly framing supply-side stagflation as structurally different from the demand-driven inflation playbook that guided markets through 2024.

The transmission mechanism from imported energy to domestic stagflation follows a clear sequence:

• Higher global energy prices worsen the Eurozone’s terms of trade, since it imports far more energy than it produces.
• Those elevated costs feed straight into business input prices and household energy bills.
• Real incomes get squeezed, so consumption slows and growth weakens.
• Yet headline inflation stays elevated, because the energy shock keeps prices high even as demand cools.

The scale of this channel is not trivial. Import prices, largely energy-linked, are estimated to have accounted for roughly 40% of the average change in the Euro area consumption deflator between early 2022 and early 2023, a period when energy costs drove much of the region’s inflation.

The central bank trap

This is where the ECB gets boxed in. It faces two mandates pulling in opposite directions: fight inflation driven partly by energy it cannot control, while avoiding a recession in an economy already growing at a crawl.

Raising rates aggressively would tackle the inflation but risk suffocating fragile growth. Holding back to protect growth would let inflation run. President Christine Lagarde called the September hike “a no brainer” on inflation grounds, but the Governing Council pointedly did not debate the future path, signalling a meeting-by-meeting stance rather than the sustained tightening the Fed can afford.

You should view the Eurozone’s energy reliance not as a passing data point but as a permanent constraint on how hard the central bank can defend the currency. When a global supply shock hits, the ECB has less room to respond than the Fed does, and the euro pays the price.

Pricing in the new political risk premium across France and Germany

Economic weakness is one thing. Political fragmentation layered on top of it is what turns a soft currency into a genuinely fragile one.

In recent German state elections, the far-right Alternative for Germany (AfD) secured victory in Mecklenburg-Western Pomerania, while the far-left Left Party placed first in Berlin. Chancellor Friedrich Merz’s Christian Democratic Union suffered significant losses. For a currency union whose stability rests on its largest economy, a rejection of the political centre in Germany is not a local story.

The concern is direct. AfD has described the euro as a “failed system” and advocates Germany leaving the common currency, which raises questions foreign investors cannot easily price.

France adds fiscal instability to the mix. During acute political stress, the French OAT to Bund 10-year spread, the extra yield investors demand to hold French government debt over German, has widened to 85-90 basis points, its highest since the sovereign debt crisis in 2012. An ING note from October 2025 recorded the spread near 86 basis points amid a prime ministerial resignation and budget risks, with the euro shedding around 0.5% against the dollar.

Not every strategist reads these as systemic. ING and Lombard Odier have characterised such episodes as one-off shocks rather than drivers of sustained depreciation, arguing that as long as crises stay country-specific, rate differentials and the dollar cycle remain the dominant forces.

When political instability threatens fiscal discipline in the Eurozone’s two largest economies at once, though, you are watching the currency’s risk premium expand in real time. That is the mechanism by which abstract headlines become measurable costs: wider spreads, higher funding needs, and capital that hesitates before committing to European assets.

European equity valuations tell a parallel story to the currency: STOXX 600 earnings grew 20-24% year on year in Q2 2026, yet the region still trades at a 40-50% forward P/E discount to the US, a gap analysts at Goldman Sachs argue is now asymmetrically mispriced given the earnings trajectory.

Historical parallels and forward trajectories for European assets

None of this is unprecedented. The euro has weathered episodes where policy divergence, energy shocks, and political strain converged, and how those resolved tells you what to watch now.

During the sovereign debt crisis, the euro depreciated by more than 10% in nominal effective terms between late 2009 and the end of 2010, according to Banco de España, as sovereign spreads soared and doubts about institutional cohesion fed on themselves. The 2022 energy shock produced a similar sell-off, driven by collapsing terms of trade and aggressive Fed tightening. The difference in 2022 is that it reversed: as energy prices fell through 2023 and 2024, headline inflation dropped and the euro recovered in effective terms.

Analysts broadly frame the current setup as a milder version of those episodes rather than a full-blown crisis. Which way it resolves depends on two variables.

Institutional positioning in Europe reinforces the currency picture: the June 2026 BofA Global Fund Manager Survey showed European equities at their most underweight since December 2024, even as Germany’s 500 billion euro infrastructure fund began disbursing, a gap between sentiment and fundamentals that parallels the currency’s own pricing problem.

The prolonged weakness scenario

If political risk and fiscal slippage in France and Germany escalate while the rate gap stays wide, the euro faces sustained downward pressure. The danger here is the interaction: widening sovereign spreads feeding sticky domestic inflation, each reinforcing the other until redenomination fears creep back into pricing, echoing the self-reinforcing dynamics of the sovereign debt years.

The gradual recovery scenario

The bullish case rests on the yield gap closing. IMF and ECB analysis stresses that terms-of-trade improvements can lift the euro’s real effective exchange rate even while spot rates lag, and the IMF’s 2025 consultation noted the euro had already reversed a sharp late-2024 depreciation. If energy prices stabilise and the Fed eventually normalises, UBS has pointed to EUR/USD recovering toward 1.20, but only once the policy gap narrows.

You have to monitor yield spreads and political stability indicators closely over the coming months. Those variables, not the headline rate decisions, will decide which path the currency takes.

Navigating the euro’s structural headwinds in late 2026

Three pressures are working on the euro at once, and treating any one of them in isolation misreads the whole. The monetary yield gap supplies the mechanical drag, structural stagflation risk sets a ceiling on recovery, and political instability in France and Germany adds a risk premium that widens with every fresh headline.

Going into the fourth quarter of 2026, the practical takeaway is to weight all three rather than fixating on the rate differential alone. The yield gap is the most visible force, but it is also the one most likely to fade if the Fed normalises. The structural and political anchors are stickier.

Currency markets tend to punish investors who watch only headline interest rates while ignoring the macroeconomic weakness underneath. Agility means reading the spreads and the politics with the same attention you give the central bank statements.
