A whirlwind of macroeconomic forces has been at play in 2025, with political turmoil and shifting monetary policy keeping analysts on their toes. After a post-pandemic boom in 2021 and a subsequent slowdown, this year has been marked by trade wars, tariff threats, and falling interest rates.

Forces like artificial intelligence and improved financial conditions are set to boost global growth in the coming years, according to the OECD. Even so, risks to output remain — including the weakening of labour markets. Growth estimates also vary widely between countries as the global order shifts, with changes notably linked to tech developments and resource dominance — among other factors.

OECD forecasts suggest that real GDP growth in the eurozone is projected to lag behind the world’s two largest economies, the US and China, in 2025. But what lies ahead for 2026 and 2027? And how are individual nations faring within the eurozone?

By the end of 2025, Ireland is projected to record the strongest growth when compared with other OECD countries, at 10.2%. This surge is “driven by front-loaded pharmaceutical exports ahead of US tariffs” according to the OECD Economic Outlook report, published in December 2025.

After a series of threats earlier this year, US President Donald Trump announced tariffs of up to 100% on imported pharmaceuticals starting 1 October. Trump said exemptions will be given to companies building an American production facility. The EU has nonetheless claimed that its exports are protected under an earlier trade deal, setting US tariffs on the bloc’s goods at 15%.

Ireland stands as an outlier in the OECD’s ranking, as the next fastest-growing countries are Turkey at 3.6% and Poland at 3.3%.

Even so, GDP in Ireland is often a misleading indicator because of the way the economy is structured. Due to the nation’s traditionally low corporate tax rates, Ireland is home to a large number of multinationals who book profits in the country, artificially distorting GDP.

At the other end of the OECD ranking, Finland is projected to show no growth in 2025. Weak consumer confidence and plummeting housing construction to correct oversupply have been heavily weighing on output, explained the OECD.

Real GDP growth in the eurozone is projected to ease modestly from 1.3% in 2025 to 1.2% in 2026, before rising to 1.4% in 2027.

Increased trade frictions will be “offset by improved financial conditions, ongoing capital spending from Recovery and Resilience Facility (RRF) funds and resilient labour markets,” said the OECD.
