The Turkish currency lira reached its peak against the U.S. dollar after Turkey's referendum on constitutional changes Sunday with a victory for the 'Yes'camp.
The lira strengthened more than 3.5 percent in Asian trade Sunday, from 3.74 to 3.63 against the greenback.
Turkish Prime Minister Binali Yildirim declared late Sunday victory for the "Yes" camp in the referendum for constitutional amendments that will change the governing system of the country from parliamentary system to presidential system.
With 99 percent of votes counted, 51.35 percent backed the constitutional changes, compared to 48.65 percent for the "No" side, according to figures by state-run Anadolu Agency.
More than 86 percent of 55 million Turkish electorates, including 1.3 million voters abroad, cast vote on Sunday.
