As the currency continued to fall, United States President Donald Trump announced on Friday he had doubled steel and aluminum tariffs on his North Atlantic Treaty Organisation ally before admitting that relations between Washington and Ankara were "not very good".
On Friday the currency dropped as much as 18 percent at onepoint, the biggest one-day fall since a 2001 financial crisis inTurkey.
Turkey's currency crisis has lurched on to the global stage, denting European and USA stocks as fears of contagion rise.
The 64-year-old also highlighted the major difficulty in battling the Kurdish insurgency which has full U.S. support for fighting Islamic State fighters in northern Syria.
The Turkish lira has lost about 40 percent this year alone, largely over worries about Erdogan's influence over the economy, his repeated calls for lower interest rates in the face of high inflation and deteriorating ties with the United States.
The lira slid to a fresh record low against the US dollar.
In the New York Times, Erdogan warned Washington not to risk relations with Ankara, saying his country would otherwise look for "new friends and allies".
"In that sense, the Turkey situation can be a contagion not only in Europe but across emerging markets", Anderson said.
Erdogan vowed there would be no easing of the law in Brunson's case: "We have not made concessions on justice so far, and we will never make any", he said.
Turkey came in sixth place among the countries the US imported steel from previous year, while Turkish steel's share was 7 percent of total USA steel imports.

"It's very unfortunate that the Trump administration had to retaliate against Turkey for their continued refusal to release Pastor Brunson and other Americans being held in Turkish custody", Graham said.
Turkey had alternatives "from Iran, to Russian Federation, to China and some European countries", he added.
USA support for Kurdish rebel groups fighting Islamic State fighters in northern Syria.is another major difficulty, given Turkey's battle against a Kurdish insurgency in its own country.
Without naming any country, Erdogan said that those - who stand against Turkey for the sake of small calculations - would pay the price.
He also repeated his call to Turks to sell their dollar and euro savings to shore up the lira.
On Friday, before Trump's tweet, Erdogan had tried to stem the sell-off by appealing to Turkish citizens to exchange any dollars, euros or gold for lira to help the currency. Gulen denies the allegation.
After nearly 20 months in a Turkish jail, Brunson was moved to house arrest in July by a court.
