The rate started trading at the 5.28 level early in the day with the parity rate retreating to a four-month low at 5.22.
It later stabilized at the 5.23 – 5.24 level before sliding back to 5.22 when domestic markets closed.
Last week, the U.S. dollar lost 0.11 percent of its value and closed the week under 5.29 against the lira.
The euro/TL exchange rate also shed some 1.3 percent and retreated to 5.3.
The sharp decline in oil prices positively affected the lira since Turkey is a major importer.
The U.S. dollar hit an all-time high against the Turkish lira at 6.89 in August as tensions were running high between Washington and Ankara over the two-year-long detention of Pastor Andrew Brunson on terror charges and the U.S.' support for the PKK terrorist group's Syrian offshoot the People's Protection Units (YPG).
President Donald Trump's administration sanctioned two Turkish ministers for Brunson's arrest, while issuing tariffs on Turkish steel aluminum products.
Relations between the two countries have remained on a positive course since Brunson's release in October, including a U.S. waiver for Turkey in oil imports from Iran amid re-imposed sanctions.
