Euro hits $1.20 as dollar slides, reviving ECB intervention debate

The euro climbed to $1.20 on Tuesday, its strongest level against the dollar since early 2021, extending a rally that made 2025 the single currency's best year since 2017. The move reflects a broader dollar sell-off that has accelerated since the turn of the year: the greenback dropped 1.3% against a trade-weighted basket on Tuesday alone, bringing its year-to-date decline to 2.6% after a 9.5% slide last year. For the eurozone, the arithmetic is uncomfortable. A stronger currency makes exports dearer abroad and imports cheaper at home, a double-edged sword that policymakers in Frankfurt are watching closely.

Why the dollar is falling

The dollar's decline has two main drivers. First, investors have grown wary of unpredictable US policymaking under President Donald Trump. When asked this week whether the dollar's slide concerned him, Trump replied: "No, I think it's great." Second, there is a deliberate strategic current. Stephen Miran, a former chairman of Trump's Council of Economic Advisers who now sits on the Federal Reserve's Board of Governors, published a "User's Guide to Restructuring the Global Trading System" in November 2024. The paper explicitly identifies tariffs and dollar devaluation as the primary instruments for correcting the US trade deficit. Whether the administration is engineering the decline or merely tolerating it, the signal from Washington is clear: a weaker dollar is not an accident.

The euro's 13% gain against the dollar in 2025 was its largest annual advance in eight years. That momentum has carried into 2026, pushing the pair through the $1.20 threshold that had acted as stiff resistance since the pandemic. The British pound and Japanese yen have also posted multi-year highs against the dollar, confirming the move is broad-based rather than euro-specific.

Competing views on the growth impact

Economists are divided on how much damage the euro's rise will inflict. Ricardo Amaro, lead eurozone economist at Oxford Economics, runs a global model that suggests Eurozone GDP would be around 0.2 percentage points lower by the end of 2026 if the exchange rate settles at current levels rather than the $1.16 reference point that prevailed after the EU-US trade agreement in late July. "If the euro continues to rise in value against the dollar, it would make European companies that export a lot to the US less and less competitive," Amaro said. He acknowledges cheaper US imports would partly offset the hit, but believes the net effect on growth is negative.

Zsolt Darvas, a macroeconomics specialist at the Bruegel think tank in Brussels, takes a calmer view. He points out that the euro traded between $1.30 and $1.50 for much of the 2004-2014 period without derailing European export performance. The current $1.20 level remains below the peaks seen in 2021. "The recent slight decline in the dollar is unlikely to cause significant economic troubles in Europe," Darvas said, adding that widespread media coverage of the falling dollar may even "encourage investors to shift their focus from US investments to the EU." He cautions, however, that exporters already jolted by Trump's tariffs last year could face "another blow" from the currency move.

Jack Allen-Reynolds, deputy chief eurozone economist at Capital Economics, strikes a middle ground. A stronger euro plays an "important role in the performance of the economy, the health of the labour market and households' financial position," he said. It makes exports less competitive, harming manufacturers, while lowering import prices for consumers. But he doubts the moves seen so far "would have a very big impact on export demand," noting that eurozone exports have been weak for years, partly because of intensifying competition from China across multiple sectors. "It certainly won't help," he added.

Sectoral exposure and the STOXX 600 link

The aggregate numbers mask wide sectoral variation. According to Goldman Sachs, companies in the STOXX Europe 600 index derive roughly 30% of their revenues from the United States. Amaro identifies pharmaceuticals and automotive as especially vulnerable, though he thinks US reliance on European pharmaceutical products may cushion the blow. Allen-Reynolds highlights the automotive sector's existing struggles with Chinese competition, suggesting the currency headwind arrives at a particularly awkward moment. For sectors with pricing power or limited US exposure, the impact will be marginal.

The ECB's intervention threshold

The euro's ascent has inevitably revived speculation about European Central Bank intervention. Martin Kocher, governor of Austria's central bank, described the recent gains as "modest" but was explicit about the condition that would force action: if the exchange rate started to lower inflation forecasts. Most analysts agree that threshold has not been crossed. Darvas puts the current inflationary impact "close to zero" and argues no sector is especially vulnerable. "Exchange rates have fluctuated widely over the past decades, and companies have adapted to manage much larger swings in exchange rates than what we are currently observing," he said.

That does not mean the ECB is passive. Amaro detects policymakers already trying to influence market expectations by stating they are "monitoring the situation and voicing some concern about recent moves." He argues this verbal intervention "brings rate cut discussions back into the table and acts against the euro appreciation momentum." Allen-Reynolds concurs that no action is warranted based on January's moves alone, but believes further appreciation could see the ECB cutting interest rates later this year. The ECB's monetary policy framework gives it room to respond if financial conditions tighten excessively.

Historical perspective: this is not 2008

Context matters. The euro's current level is striking only because the dollar has been exceptionally strong for the past three years. From a longer perspective, $1.20 is unremarkable. Between 2004 and 2014, the euro spent much of its time above $1.30, frequently testing $1.50. European exporters adapted then through productivity gains, value-chain upgrading and market diversification. The Eurostat trade data from that period shows export volumes growing despite the strong currency. The difference today is the simultaneous arrival of US tariff threats, Chinese overcapacity in key sectors, and an eurozone economy that has barely grown for two years. The currency is an additional headwind, not the sole story.

What the ECB watches next

The central bank's reaction function is now tied to two variables: the pace of further euro appreciation and the incoming inflation data. If the euro climbs toward $1.25 without a corresponding improvement in domestic demand, verbal intervention will intensify and markets will price deeper rate cuts. The ECB's reference exchange rate page will be monitored daily by trading desks across Frankfurt. For now, the governing council can credibly argue that a 13% annual move, while large, merely reverses part of the dollar's post-pandemic surge. But credibility is a wasting asset. If the dollar slides another 5% by spring, the debate will shift from whether to act to how aggressively.
