🇵🇱 Poland
Poland kept its own currency – the zloty – and Narodowy Bank Polski sets policy independently of the ECB. That gives more policy freedom than euro-area countries. It does not, however, make the zloty hard money. Official inflation has still eaten zloty purchasing power.

Purchasing power of 100 PLN
Poland avoided joining the euro and retained control over its own monetary policy. Even so, the sharp inflation spike of 2022–2023 and the years that followed cut the real value of a zloty by more than a third since 2015.

Why this matters in Poland
Own currency is better – but not enough
Having an independent currency and central bank is a clear advantage over euro membership. Poland can set its own interest rates and respond to domestic conditions. That does not stop the zloty from losing purchasing power when NBP and the banking system expand the money supply.
Rising debt is not a shield
Maastricht debt was 61.6% of GDP in Q1 2026, about PLN 2.44 trillion (Eurostat). That is moderate next to euro-area peers above 100% of GDP, but it is still rising — from 57.0% a year earlier. The zloty inflates anyway. Debt is a fiscal fact, not a currency shield.
The same hidden tax, just domestic this time
Whether new zlotys are created to fund government borrowing, energy subsidies or defence spending, the effect on Polish wages and savings is the same: existing zlotys buy less over time. The tax is not imported from Frankfurt. It is home-grown money creation. Savers and wage earners pay.
