Turkey has vowed to take measures later today to calm market fears sparked by the precipitous plunge in the lira's value as its president accused Washington of spearheading an "underhand plot" against his country.
The dispute between the two NATO 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.
It caused global market jitters last week as investors fretted over potential economic contagion from Turkey, particularly to European banks.
Overnight it fell to a new record low of 7.2362 to the dollar before recovering to around 6.8222 in early Asian trading, similar to its trading price on Friday.
"Our institutions will take necessary action from Monday in order to relieve the markets," he said, adding that the plan would centre on "the state of our banks and the small and medium size enterprises" most affected by the lira's plunge.
Albayrak's comments came as his father-in-law, President Recep Tayyip Erdogan, said he was in no mood to offer concessions to the United States in one of the worst spats between the two NATO allies in years.
"We are once again facing a political, underhand plot. With God's permission we will overcome this," he added.
Erdogan appeared unworried by the punitive measures imposed by the US, saying Turkey could turn to other partners and again terming the crisis an "economic war".
"We will give our answer, by shifting to new markets, new partnerships and new alliances, to the one who waged an economic war against the entire world and also included our country," Erdogan said.
Erdogan appeared to indicate that the entire alliance between Turkey -- which joined NATO in 1952 with strong American backing -- and the US was at stake.
"We can only say 'good-bye' to anyone who sacrifices its strategic partnership and a half century alliance with a country of 81 million for the sake of relations with terror groups," he said.
"You dare to sacrifice 81-million (in) Turkey for a priest who is linked to terror groups?" American pastor Andrew Brunson has been held since October 2016 on charges of terror and espionage, and if convicted, could face a jail term of 35 years. Trump has described his detention as a "total disgrace" and urged Erdogan to free him immediately.
Washington earlier this month already imposed sanctions on senior Turkish officials over the Brunson case, angering Erdogan and prompting retaliatory measures by Ankara.
In Trabzon, Erdogan confirmed media reports that Washington gave Onal's delegation a deadline for the release of Brunson.
"They tell us to release the priest by Wednesday 6:00 pm, otherwise the sanctions will begin," said Erdogan, adding Turkey was not a country to agree to such requests.
Analysts say that while Washington's sanctions against Ankara sparked the immediate crisis, Turkey's economy has been risking trouble for a while due to high inflation and the weak lira.
The central bank has over the last few weeks defied calls from markets for rate hikes to combat these problems, raising fears of interference from Erdogan who has repeatedly called for low interest rates.
Erdogan had on Saturday described interest rates as a "tool of exploitation", in remarks that may not be warmly welcomed by the markets.
Erdogan also hit back at US authorities for convicting Mehmet Hakan Atilla, 47, deputy director general of Turkish lender Halkbank on charges of helping Iran evade US sanctions on billions of dollars of oil proceeds.
