Warsaw’s stock index fell on Thursday and the zloty slid, with banks selling off on an EU legal opinion that a Polish official said risked triggering an economic crisis in the eastern European nation.

Poland’s largest lender, PKO Bank Polski SA, fell as much as 7.2%, while Commerzbank AG’s Polish unit MBank SA dropped 6%, dragging the overall WIG20 index down as much as 1.5%, among the worst losses in emerging markets. The currency also took a hit, sliding 0.5% against the euro.
