At least three state-backed agencies have reduced the frequency of their publications of economic and polling data over increasingly worrisome figures this year. Low oil prices and Western sanctions, as well as Russia’s expenditures on its military campaign in Syria and a reported backing of pro-Russian separatists in Ukraine, have put a dent in many Russians’ savings.

The investment arm of Russia’s biggest lender Sberbank had abruptly stopped publishing its consumer confidence figures for three consecutive quarters in 2018-19 until they rose again later this year, Russia’s The Bell business outlet reported Monday. Known as the “Ivanov index,” the measure of consumer confidence said that the share of Russians who consider themselves middle class had fallen from 60% in 2014 to 47% last year. “There was a decrease in consumer confidence caused by a set of factors during 2018,” Mikhail Krasnoperov, Sberbank’s leading consumer sector analyst, told The Bell in a written statement Monday without explaining the reason for the investment arm's gap in publications. “The confidence index is recovering in 2019 against the backdrop of improving expectations for the country’s economy, personal prosperity and growth of confidence in business,” Krasnoperov was quoted as saying.
