Recep Tayyip Erdogan was responding to a drop in the value of the Turkish currency, the lira, against the us dollar following the imposition of sanctions and tariffs by the United States in the past two weeks.
The Turkish economic situation is very critical, as political issues pushed the economy to suffer several risks, which recently was shown in the Lira's fall, mentioned Sherif El-Diwany, former head of the Middle East at the World Economic Forum in Geneva, adding, "Turkey now is an unstable market".
Reverberations spread through global markets, with European stock markets especially hit as investors took fright over banks' exposure to Turkey.
Turkey's currency fell Friday after its economy was rattled by the United States' move to slap the country with more tariffs. He tweeted, "Our relations with Turkey are not good at this time!"
The penalties also bar any USA transactions with the two men. "We will be taking the necessary steps with our banks and banking watchdog in a speedy manner", he said.
Erdogan said high foreign exchange rates were the means used in plots against Turkey.
President Donald Trump said on Friday he'd authorised higher tariffs on imports from Turkey.
The Turkish strongman also lashed out at interest rates, denounced them as a "tool of exploitation" which should be kept as low as possible.
The Trump administration threatened to impose additional sanctions on Turkey if it did not meet the deadline, Erdogan said.
He reiterated his call on citizens to change US Dollars and Euros for the Turkish Lira in the face of a sharp plunge his country's currency witnessed in financial markets this week. Trump said on Twitter.
"If you advance upon us by the dollar, we will look for other means to carry on our business", he added.
The Turkish president was referring to American pastor Andrew Brunson, who is accused of ties to Erdogan's arch-nemesis, Muslim cleric Fetullah Gulen, who lives in exile in Pennsylvania, and whose extradition the Turks have been demanding on the grounds that he organized the 2016 coup attempt against the Erdogan regime. Gulen has denied the allegation.
The 50-year-old American pastor, who has been charged with "committing crimes on behalf of terror groups", was moved out of prison last month and placed under house arrest.
The dispute between the two North Atlantic Treaty Organisation allies - which reached new intensity over the detention of an American pastor in Turkey - has hammered the lira and also raised questions over the future partnership between Washington and Ankara.
A Turkish court has transferred Brunson to house arrest after nearly 20 months in jail.
His cause resonates with Mr Trump's Christian conservative supporters.
Jay Sekulow, an attorney for Trump who is also representing Brunson's family, told talk-show host and political commentator Sean Hannity's radio program on Friday: "We're close to getting a resolution in that case".
