Mr Erdogan appealed for calm and renewed a call on people to change foreign money into local lira.
"There are various campaigns being carried out".
On Friday afternoon Erdogan dug in again, calling for citizens to convert out of dollars and gold and buy the lira to help fight a "national struggle".
Turkey's treasury and finance minister Berat Albayrak - who is Mr Erdogan's son-in-law - tried to ease investor concerns during a conference, saying the government would safeguard the independence of the central bank.
Without naming countries, Erdogan said supporters of a failed military coup two years ago, which Ankara says was organized by a USA -based Muslim cleric, were attacking Turkey in new ways since his re-election two months ago to a new executive presidency. In his speech in the northeastern city of Bayburt, Erdogan added that he would decisively defend the country against economic attacks.
The lira tumbled about 10 per cent on Friday to another record low as investors worry about Erdogan's unorthodox economic policies and USA sanctions.
Presenting the government's new economic model, Albayrak said the next steps of rebalancing would entail lowering the current account deficit and improving trust.

That said, the global threat from Turkey's debt problems is relatively small. It has fallen by over 35% this year. "I used to sell 100kg of meat, but eventually I started to sell 10kg in the same period of time", he said.
