Persistent concern over political interference in Turkey's central bank rose after Sunday's remarks by President Tayyip Erdogan criticising interest rate policy, the latest call for the bank to cut rates to boost growth.
In addition, an Erdogan aide said late on Monday it would be the central bank's fault if the lira became a problem and that it still had room to reduce interest rates by up to another 75 basis points.
The lira fell to a record low of 2.5 by 1400 GMT, a day after touching a previous record low of 2.4993 on Monday.
Turkey's central bank has so far resisted a rate cut and ruled out a meeting before the regularly scheduled Feb. 24 date.
