Tensions between the two North Atlantic Treaty Organisation allies have been strained amid Turkey's detention of American pastor Andrew Brunson.
The lira has lost almost 40 per cent against the dollar this year, driven by worries over Mr Erdogan's growing control over the economy and his repeated calls for lower interest rates despite high inflation.

"The tariffs from Turkey are certainly regrettable and a step in the wrong direction", White House spokeswoman Sarah Sanders told reporters.
"Turkey has alternatives", he said. "The tariffs are specific to national security", she said.
He also declared on Monday that the USA was seeking "stab" Turkey in the back.
