ISTANBUL: Turkey braced on Saturday for a new spell of financial turbulence after President Recep Tayyip Erdogan sacked his market-friendly central bank chief and replaced him with a former ruling party lawmaker.

A presidential decree published late on Friday gave no explanation as to why Erdogan was replacing Naci Agbal with Sahap Kavcioglu in the key post.

But the decision was announced just a day after the central bank sharply raised the main interest rate to 19 percent to fight inflation.

Kavcioglu has written columns for a pro-government newspaper heavily criticising Agbal's propensity to raise rates.

Analysts say the new central banker subscribes to Erdogan's unorthodox belief that higher interest rates cause inflation.

Most economists believe it slows inflation down by raising the cost of doing business.

"The shock decision by Turkey's President Erdogan to sack central bank governor Naci Agbal late on Friday is likely to trigger large falls in the lira when markets open on Monday," analyst Jason Tuvey of Capital Economics wrote in a research note.

"It looks like the central bank's efforts to fight the country's inflation problem may come to an end, and a messy balance of payments crisis has become (once again) a real possibility," Tuvey warned.

Agbal was appointed during an economic team overhaul that Erdogan engineered in November to halt a steep Turkish currency slide.

The lira had by then fallen to 8.5 to the dollar from 5.9 at the start of 2020 as past central bank managers kept interests rates low while inflation gathered pace.

Economists at Goldman Sachs estimated that the central bank spent more than $100 million in 2020 alone buying up foreign currencies in an attempt to support the lira.

But Turks kept stocking up on gold and exchanging liras for euros and dollars to preserve their saving.

Foreign investors fled the Turkish market and the economy appeared headed for a major crisis.
