The U.S. Federal Reserve's recent decision to taper its asset purchases has hurt nearly all emerging market currencies, Turkey suffered one of the worst selloffs. The Turkish lira has fallen 30 percent since May, a decline also driven by political drama within the country that has unnerved investors.
Simsek insisted—not for the first time—that the country's central bank is independent from political influence.
"We have to be pragmatic," he said. "The most important thing for us is central bank credibility and its independence, because it's a challenging global backdrop, challenging global environment, and I have to deal with that."
There were questions about the Turkish central bank's independence when it initially chose not to raise interest rates in the face of a sharp selloff in the currency. The subsequent drop was so sharp that the bank reversed course, declared an emergency meeting and announced a massive rate hike in the middle of the night last week.
The currency has since stabilized at roughly 2.26 to 2.27 lira to the dollar.
