Turkish inflation surged to nearly 25 percent in September from a year earlier, official data showed on Wednesday, hitting its highest in 15 years and sharpening focus on whether the central bank will be able to deliver another hefty rate hike, Reuters reported.

The size of the increase - prices jumped by 6.3 percent from a month earlier - far outpaced expectations and underscored the deep impact of a currency crisis on the economy and consumers.

The lira has lost nearly 40 percent of its value this year, hit by concerns about President Tayyip Erdogan’s influence over the central bank and a rift with Washington. The sell-off has pushed up prices of everything from food to fuel and eroded confidence in what was once a high-flying emerging market.
