I recently took a closer look at the Euro (EUR) to Zloty (PLN) exchange rate—and honestly, the topic is more fascinating than it seems at first glance. My Polish neighbor had advised me to be pessimistic about the Polish currency due to the political situation and the war in Ukraine. But as someone who follows markets, I didn’t want to just let that be the whole story. So I started working through the fundamentals.

First, the current situation: Poland has been in the EU since 2004, but it still hasn’t adopted the euro. That means we can still trade PLN against EUR. For a long time, the exchange rate stayed relatively stable at just over 4 PLN per euro—apart from the usual crises in 2001 and 2008. What caught my attention, though: in recent years, the Euro (EUR) to Zloty (PLN) rate has actually fallen, even though it rose significantly after the war in Ukraine. That suggests something fundamental has changed.

I looked at six factors that influence the exchange rate. For inflation, the picture is this: in 2024, Poland was at 3.7%, while the eurozone was only at 2.4%. For 2025 and 2026, a decline is expected in both regions, but the eurozone remains significantly lower. That could point in favor of the euro—at least on the surface.

Interest rates are different. Poland currently has 4.75%, while the eurozone has only 2.0%. Higher interest rates normally make a currency more attractive because they draw in foreign investment. That’s a point in favor of the Złoty. On top of that, there’s GDP growth: according to the EBRD, Poland should be able to count on 3.5% per year, while the eurozone is expected to grow by only 1.2% in 2025 and 1% in 2026. Even the unemployment rate in Poland is clearly better at 3.1% than the eurozone’s 6.2%.

On the other hand, there are stress factors. Poland’s public debt has risen to over 416 billion euros by Q2 2025—a clear upward trend. And of course, the war in Ukraine directly affects Poland as a direct neighbor with millions of Ukrainian refugees. That comes with a cost.

As for forecasts, analysts don’t agree on the Euro (EUR) to Zloty (PLN) exchange rate. Some expect a drop to 4.20, while others see values as high as 4.44 by the end of 2026. Erste Group forecasts 4.30. The takeaway: it could go in either direction.

My take? In the past few months, the Złoty has strengthened significantly against the euro, and there are solid reasons for that—higher interest rates, stronger GDP growth, and lower unemployment. So my neighbor, with his pessimistic view, wasn’t quite right. But the higher inflation and geopolitical risks also don’t support a one-sided rally.

For traders, that means: be cautious with the Euro (EUR) to Zloty (PLN). A sideways move with a slight upward bias is likely. The daily ranges aren’t particularly large, which allows for more relaxed trading. If you work with carry trade strategies, you might find interesting setups here—the interest rate differential between Poland and the eurozone isn’t insignificant.

Conclusion: The Euro (EUR) to Zloty (PLN) exchange rate remains an exciting currency pair for anyone who knows a thing or two about fundamentals and doesn’t just want to wait for spectacular moves. And hey, you can also have great conversations with Polish friends—more than just neighborhood small talk.
