Turkish inflation rose to a 24-year high of 79.6 per cent in July, as the lira's continued weakness and global energy and commodity costs pushed prices higher.
Despite the climb, price rises came out below forecasts.
Inflation began to surge in the last northern autumn, when the lira slumped after the central bank gradually cut its policy rate by 500 basis-points to 14 per cent in an easing cycle sought by President Tayyip Erdogan.
Month-on-month, consumer prices rose 2.37 per cent in July, the Turkish Statistical Institute said. Annually, consumer price inflation was forecast to be 80.5 per cent.
Jason Tuvey, senior emerging markets economist at Capital Economics, said annual inflation may be approaching a peak with energy inflation falling sharply and food inflation appearing close to topping out.
"Even if inflation is close to a peak, it will remain close to its current very high rates for several more months," Tuvey said in a note.
"Sharp and disorderly falls in the lira remain a key risk," he said.
The biggest annual rise in consumer prices was in the transport sector, up 119.11 per cent, while food and non-alcoholic drinks prices climbed 94.65 per cent.
Inflation this year has been fuelled further by the economic impact of Russia's invasion of Ukraine, as well as the lira's continued decline.
The currency weakened 44 per cent against the US dollar last year, and is down another 27 per cent this year.
The lira was trading flat after the data at 17.9560 against the dollar. It touched a record low of 18.4 in December.
Annual inflation is now at the highest level since September 1998, when it reached 80.4 per cent.
The government has said inflation will fall as a result of its economic program, which prioritises low rates to boost production and exports and aims to achieve a current account surplus.
Erdogan has said he expects inflation to come down to "appropriate" levels by February-March next year, while the central bank raised its end-2022 forecast to 60.4 per cent last Thursday from 42.8 per cent previously.
The bank's inflation report showed the estimated range of inflation reaching nearly 90 per cent by the northern autumn before easing.
Opposition MPs and economists have questioned the reliability of the Turkish Statistical Institute's figures, claims the institute has dismissed.
Polls show Turks believe inflation is far higher than official data.
