Is the Golden Dream of the PLN Over? Dollar and Euro Rebound as Key US Data Looms
The Polish Zloty is ending the long May weekend in noticeably weaker shape. After a period of undisputed dominance of the Polish currency across emerging markets, the major pairs are returning to growth—the US Dollar is testing the 3.65 PLN barrier, and the Euro is breaking through the 4.26 PLN ceiling. Investors have begun taking profits, but local sentiment will not dictate the direction for the coming days. For traders, today’s afternoon economic readings from the US will be crucial, determining the further fate of the EUR/USD pair and indirectly the risk appetite in Central Europe.

The Zloty Loses Its Shine. What Happened After the Long Weekend?
The Polish currency was long the darling of foreign investment funds, benefiting from the influx of EU funds and the relatively hawkish policy of the central bank. However, May 5, 2026, brings a market sobering. Investors, after months of holding long positions on the Zloty, began taking profits en masse ahead of the summer season. Yesterday’s cool readings of the PMI index for the Polish manufacturing sector added to this, proving that the “soft landing” of the local economy can still hit bumps in the road.
As a result, the US Dollar swiftly checked in at the 3.65 PLN mark, and the European currency decisively crossed the 4.26 PLN boundary. The domestic currency is also losing ground to safe havens, including the Swiss Franc (CHF), whose dynamic rise clearly suggests that global capital is taking a more cautious approach to risk in Emerging Markets.
Watch Out at 4:00 PM. ISM for Services Will Deal the Cards
Whether the current correction on the Zloty turns into a strong, long-term downtrend depends largely on today’s data from the United States. At 4:00 PM CET, the markets will learn the reading of the ISM index for the US service sector for April. Since services account for the lion’s share of US GDP, this is currently one of the most important barometers of the economy’s health, closely monitored by the Federal Reserve (Fed).
The correlation between today’s data and traders’ decisions in the currency market will be direct and brutal. For active investors, this is the perfect moment to prepare an appropriate strategy (e.g., setting a grid of pending orders), because after 4:00 PM we can expect heightened volatility, which will be dictated by the specific macroeconomic reading.
| ISM Services Reading Scenario | US Dollar (USD) Reaction | Impact on Polish Zloty (PLN) |
|---|---|---|
| Significantly above expectations (strong inflationary pressure) | Sharp strengthening of the Dollar, decline on the main EUR/USD pair. | Strong sell-off of the Zloty, likely push of the USD/PLN rate toward 3.70 PLN. |
| Below expectations (signs of a sharp slowdown) | Sell-off of the US currency, return to growth on EUR/USD. | Calming of the situation on the PLN, return of investors to higher-risk assets. |
