Russia's CPI rose by 0.33 percent in the week ending Dec. 23, and inflation this year has reached 9.5 percent, according to the latest weekly data released Wednesday by Russia's National Statistics Agency. The data comes after the Bank of Russia's surprise decision last week to leave its key interest rate unchanged at 21 percent. The regulator said recent tightening policies have created favorable conditions to reduce inflation to its target of 4 percent. Andrei Gangan, head of the central bank's monetary policy department, said full-year inflation in Russia will be between 9.6 percent and 9.8 percent.
