The Turkish central bank and finance ministry declined to immediately comment on the subject. JP Morgan did not immediately reply to a request for comment.

After May elections President Tayyip Erdogan signalled a U-turn towards more orthodox economic policies and appointed former Wall Street banker Erkan and respected veteran policymaker Simsek as Turkey's top economic team.

They face the challenge of tackling economic strains that have sent the lira to consecutive record lows, fuelled high inflation and eroded tens of billions of dollars of foreign exchange reserves in recent years.

One of the sources said Simsek would share with the investors details on the actions taken on the economy by the new administration since the elections. Aside from interest rate hikes, there have been other tightening measures and tax hikes.

Last week at her first news conference since taking over the post of governor in June, Erkan said she would soon be holding meetings with investors.

Under the previous governor, the central bank slashed its policy rate to 8.5% from 19% in 2021 in line with Erdogan's unorthodox belief that high rates fuel inflation. The cuts sparked a currency crisis and the lira weakened 44% in 2021, 30% in 2022, and another 30% so far this year.

Annual inflation touched a 24-year peak of 85.5% last October and although it eased back in subsequent months it rose sharply again in July to nearly 48%, data showed on Thursday.

The lira was slightly weaker at 26.9870 against the dollar after the data, just off a record low of 27.05.

Since Erkan took charge, the central bank has hiked its policy rate by 900 basis points to 17.5%, but the pace of tightening has remained below market expectations. Last week the central bank more than doubled its year-end inflation forecast to 58%, in line with market expectations.
