Iwona Duda and Gabriela Maslowska join the MPC as the rate-setting body grapples with soaring inflation and slowing economic growth.

Both were nominated by the ruling nationalist Law and Justice (PiS) party and fill two vacant posts on the 10-member MPC.

Duda was chief executive of Poland's largest lender PKO BP from 2021-22, and before that she was president of the management board of Alior Bank.

Maslowska is a PiS lawmaker and a member of the parliamentary public finance committee.

On Wednesday the Polish central bank left its main interest rate unchanged at 6.75% after a run of 11 straight rate hikes.

Governor Adam Glapinski said on Thursday that the bank will wait until its next inflation projection in November before deciding if more policy tightening is needed.
