PARIS: As the euphoria of a municipal election drubbing for President Recep Tayyip Erdogan ebbs, Turks are left watching their wallets with inflation that has sapped the longtime leader’s appeal driving up costs for everyday basics.

Even as the government vows austerity measures and the central bank hikes rates, price growth “is not stopping, it’s going up”, said economist Murat Sagman, founder of Sagam Strategy Advisory.

Official data released Wednesday put year-on-year price growth at 68.5 percent in March, up from 67.07 the previous month.

ENAG, a group of independent economists, said their own calculations put the annual figure at almost 125 percent and rising.

“In the market, (it’s) one price in the morning, another price in the evening. I can’t make a living if I sell this corn at a cheaper price,” said Osman Karakoc, 64, selling grilled cobs for 30 lira ($0.93) apiece from a small cart outside a mosque at Istanbul’s Egyptian Market.

“It’s the product of our country, but we can hardly buy it,” he added.

Erdogan, in power since 2003, was once feted for Turkey’s economic success story, but in recent years it has become his Achilles heel.

Some of the surge in price growth over recent years was down to Erdogan’s unorthodox views on monetary policy.

The Islamic conservative president long blamed inflation on high interest rates, whereas mainstream economists see increasing the cost of borrowing as a way to brake activity and thereby ease pressure on prices.

More recently, Erdogan has allowed Turkey’s central bank to hike its main policy rate from just 8.5 percent before his re-election last May to 50 percent last month.

But the monetary authority lists other factors still feeding inflation, including a weak lira currency — down 40 percent against the dollar in a year — a massive jump in the minimum wage in January and surging costs for food and fuel.

The government must follow through on its promises to slash spending to flank the central bank’s efforts to slow price growth, Sagman said.

“It’s the only way to lower inflation, to make the whole policy tight for a certain period of time,” he said.

Nicholas Farr of Capital Economics commented that “further monetary tightening lies in store... a more concerted effort to tighten fiscal policy will be needed too”.

“We will do whatever is necessary until we reach our goal of price stability, which is our top priority,” Finance Minister Mehmet Simsek said Wednesday.
