Naci Agbal, who preceded Kavcioglu at the central bank, served less than five months as governor and was appointed a day after the lira logged its last record low in November.
The currency had declined on expectations of worsening ties between Ankara and Washington. Further pressuring the lira, Central Bank Governor Sahap Kavcioglu on Friday defended forex reserve sales under a previous administration aimed at providing support for the lira and said further rate hikes could damage the economy.
The lira stood at 7.44 against the US dollar at 0720 GMT, firming from Wednesday's close of 7.5120. It climbed as much as 7.7840 on Monday as yields on US bonds rose.
