What does USD/PLN measure?

USD/PLN states how many Polish zloty you receive for one US dollar. A rate of 4.00 means one dollar buys 4.00 zloty.

Does Poland use the euro?

No. Poland is an EU member state but has retained the zloty and its own central bank, Narodowy Bank Polski (NBP), rather than adopting the euro.

Why does USD/PLN often move with EUR/USD?

Most zloty trading is referenced against the euro (EUR/PLN) rather than the dollar directly, since Poland's economy is closely tied to the eurozone. USD/PLN therefore tends to reflect EUR/PLN combined with the separate EUR/USD rate.

Is this rate live or a daily reference?

The API response for this pair carries a source and market_session field on every call, so you always know whether the quote reflects a live intraday tick or a daily reference fix — the rate can update intraday through the trading week, but no fixed refresh interval is guaranteed.

Does the NBP intervene in the currency market?

The zloty floats, but Narodowy Bank Polski has at times intervened to smooth excessive short-term volatility rather than to defend a fixed level.

What are the main drivers of USD/PLN?

Eurozone growth, capital flows within the EU, the interest-rate gap between the NBP, ECB, and US Federal Reserve, and broader CEE regional risk sentiment all factor into how the zloty trades.

How do I get this rate via the API?

GET /v1/latest/USD?symbols=PLN returns the indicative rate, source, market_session, and timestamp. The free tier covers it, no credit card required. All rates are indicative, not for settlement.

USD/PLN — US Dollar to Polish Zloty

USD/PLN expresses how many Polish zloty one US dollar buys. It is the standard reference for trade and investment flows between the United States and Poland, the largest economy in Central and Eastern Europe (CEE).

The zloty floats under Narodowy Bank Polski (NBP), Poland's central bank, though the NBP has at times intervened to smooth excessive volatility. Poland is an EU member state that has not adopted the euro, so the zloty remains sensitive to eurozone growth, EU capital flows, and the interest-rate differential between the NBP, the European Central Bank, and the US Federal Reserve.

Most zloty trading activity actually references EUR/PLN rather than the dollar pair directly. As a result, USD/PLN largely reflects a combination of EUR/PLN and the separate EUR/USD rate, rather than dollar-zloty dynamics in isolation.

This page shows an indicative mid-market rate that can update intraday through the trading week. It is not a live intraday quote for settlement or regulated trading — every API response carries source and market_session so you can see whether a given number reflects a live tick or a daily reference fix.
