ISTANBUL: Turkiye’s central bank was expected Thursday to dramatically raise its key interest rate for the second month running following a sudden turn towards conventional economics by President Recep Tayyip Erdogan.

The mercurial Turkish leader performed one of his trademark policy reversals after winning a difficult re-election in May.

The vote came during Turkiye’s worst economic crisis in decades – one that analysts universally blamed on Erdogan’s unorthodox conviction that high interest rates contribute to inflation.

Erdogan called high rates “the mother and father of all evil” and spent years pushing the central bank to lower borrowing costs to speed up economic growth.

He also made low rates the mantra of his re-election campaign.

But the annual inflation rate is again rising after officially peaking at 85 percent 11 months ago.

It approached 60 percent in August and is climbing much faster than projected by Erdogan’s new economic team of former Wall Street executives and respected technocrats.

That team has been widely applauded for convincing Erdogan that Turkiye would enter a systemic crisis unless rates were immediately and substantially raised.

The policy rate has now moved up from 8.5 percent at the time of Erdogan’s re-election to 25 percent last month.

The central bank raised it by a whopping five percentage points in August and is expected to do so again on Thursday.

A hike to 30 percent would take the policy rate to its highest level in two decades – a move Erdogan effectively blessed by pledging support for “tight monetary policy” this month.

Brighter outlook

Economists still worry that Turkiye is flirting with peril because interest rates remain far below levels at which consumer prices are going up.

This gives Turks the incentive to spend their savings before they lose value and is making Turkiye’s economy overheat.

“Turkiye’s economy isn’t slowing anywhere near as quickly as we thought it would a few months ago,” Capital Economics consultancy analyst Liam Peach wrote this month.

Fitch Ratings this month improved Turkiye’s outlook from “negative” to “stable” thanks to the policy U-turn.

But it also warned that “there is still uncertainty regarding the magnitude, longevity and success of the policy adjustment to bring down inflation, partly due to political considerations”.

Finance minister Mehmet Simsek – the former Merrill Lynch strategist Turkish media credit with changing Erdogan – expects to keep rates elevated until the middle of next year.

“Starting from the second half of 2024, we will be discussing lowering interest rates,” he said this month.

But Simsek has a second major problem.

‘Unexploded hand grenade’

Turkiye’s finances are also being weighed down by a hugely costly bank deposit support scheme that compensates the lira’s loss in value against hard currencies.

Unwinding that system could spook depositors to buy up dollars and put renewed pressure on the lira – its value down from 10 to the greenback two years ago to 29 this week.

Simsek took the first cautious steps towards scaling back the support measures last month.

But he later told reporters that he wanted to “reinforce our (hard currency) reserves” so that Turkiye could better support the lira before making any more radical cuts to the $124 billion scheme.

Emerging markets economist Timothy Ash called the programme “an unexploded hand grenade placed in Simsek’s pocket by the outgoing team”.

“The problem is that the lira needs to be allowed to adjust weaker given high inflation, but each move weaker costs the (central bank) in compensation paid to depositors,” Ash said.

“Much higher policy rates, taking them positive in real terms would be the solution… but it might also need the confidence shock of an external anchor – an IMF programme.”

Erdogan has repeatedly rejected the idea of seeking the International Monetary Fund’s support.
