The collapse in the Turkish Lira, which has been relentless since last summer’s failed coup, has only accelerated in 2017, and especially this morning, when the Turkish currency tumbled more than 2% against the dollar – its single worst day since the July 19 military coup attempt – sliding as low as 3.73, down over 5% so far in 2017, and over 23% in the past 12 months.
