The dollar edged down against the Turkish lira Tuesday after Turkey's central bank held interest rates steady, as expected. In January, the central bank hiked short-term rates in response to a what it called "significant depreciation" in the lira. The central bank said Tuesday its monetary tightening in January had helped contain risks to inflation expectations in the medium term but said inflation is expected to rise until June. The dollar traded at 2.2187 lira versus 2.2202 late Monday, according to FactSet
