Turkey's main share index however tumbled 5.94%, falling with global shares, as oil fell and coronavirus fears lingered.
The lira has weakened nearly 3% this year, having slid 36% in the previous two years following a 2018 currency crisis. Output hikes by Saudi Arabia and Russia slashed oil prices by as much as a third, a historic rout that hit energy-exporting emerging markets hard.
But since Turkey imports virtually all of its oil and natural gas, economists said the selloff could keep a lid on the country's historically lofty inflation and current account deficit.
Sekerbank Chief Economist Gulay Elif Yildirim said every $10 drop in the price of a barrel of oil trims the deficit by as much as $3.5 billion.
Were oil to remain at current levels though year-end, Turkey's current account deficit would be $10 billion lower than otherwise, she said, adding uncertainties around energy production and the effects of the coronavirus are big wild cards.
