Poland’s Bank-Tax Plan Sinks Stocks as Budget Risks in Focus

Poland’s plan to increase taxes on banks jolted investors, wiping 33 billion zloty ($8.9 billion) off the valuations of Warsaw-listed lenders.

Warsaw’s benchmark WIG20 stocks gauge sunk 4.7% on Friday, the biggest decline among primary indexes tracked by Bloomberg. The WIG-Bank sub-index dropped 9.5%, the most since a global selloff stoked by US tariff announcements in April.
