BELEK: Turkish President Tayyip Erdogan renewed his call for lower interest rates on Sunday, saying they were too high to encourage investment and entrepreneurship, an argument likely to unnerve investors already worried about central bank independence. Long a champion of populist economics, Erdogan has repeatedly called for lower rates to spur growth, equating higher financing costs with treason. Economists say Turkey’s central bank needs to hike rates to rein in inflation. Its refusal to do so has sparked worries about political interference in monetary policy, helping send the lira currency to a series of record lows this year.
