Turkey's central bank governor Murat Cetinkaya was fired by presidential decree, local media reported on Saturday.
Cetinkaya, who has held the role since April 2016, was replaced by his deputy Murat Uysal.
The decree, published in the official gazette, gave no official reason for the dismissal but speculation is rife that Cetinkaya had fallen out with Turkish President Recep Tayyip Erdogan over cutting interest rates.
Last September, as the country's debt crisis worsened and the currency plummeted by 30%, the governor hiked the interest rate by 625 basis points to 24%, where it has remained ever since.
Erdogan has repeatedly railed against high rates, calling them the "mother and father of all evil" and urging them to be lowered in a bid to stimulate growth.
Erdogan tightens grip
In a sign of his attempt to control monetary policy, last year Erdogan appointed his son-in-law Berat Albayrak as finance and treasury minister, which further spooked investors.
The Turkish economy slipped into recession earlier this year as the lira continued to weaken and soaring inflation took a heavy toll on overall output.
Last October, inflation hit a 15-year high above 25%, although it fell to 15.72% in June.
Uysal insisted he would continue to use monetary policy tools "independently" while remaining focused on ensuring price stability as his "main aim," according to a central bank statement.
Analysts expect the bank could ease monetary policy at a July 25 meeting if the lira is not hit this month by threatened US sanctions over Turkey's purchase of a Russian missile defense system.
