Turkey’s lira weakened the most among major world currencies on Tuesday, falling as much as 1.6 per cent to a new record, as the killer of 39 people at an Istanbul nightclub remained at large and inflation accelerated more than estimates in December.

The lira depreciated to a record 3.60 against the dollar before trading 1.3 per cent lower at 3.5897 as of 2.16pm in Istanbul, bringing its decline over the past 12 months to 19 per cent. The annual inflation rate was 8.53 per cent last month, above all estimates and more than 3.5 percentage points above the central bank’s target, Turkey’s official statistics agency said earlier in the day.

The deterioration in economic data, including negative growth in the third quarter and consumer confidence near record lows in December, is compounded by increasing security risks. Daesh claimed the New Year’s attack at the Reina nightclub shortly after Istanbul rang in the new year, and Turkish authorities have yet to track down the killer.

“Market participants are looking for signs that the central bank is taking the inflation threat seriously,” said Henrik Gullberg, a strategist at Nomura in London who said he predicted the currency would fall past 4.00 in the first six months of the year. “Until we see aggressive policy tightening, similar to early 2015, the lira will continue to sell off on bad news like the terrible terror attack, whilst not appreciating back when sentiment is more supportive.” Following the jump in consumer prices, “the pressure on the central bank to respond is likely to increase,” Morgan Stanley analyst Ercan Erguzel said in an emailed report on Tuesday. The Turkish central bank will probably increase the policy rate by 25 basis points when it meets on January 24, he said.

Bulent Gedikli, an adviser to President Recep Tayyip Erdogan, said such calls were just a “market-hurting cliche.” Erdogan and his economic team say interest rates should be cut to boost growth and investment.

“Raising interest rates in this period would break the economy’s back, that’s all,” Gedikli said via Twitter.
