McDonald’s Corp. (MCD.N) will open fewer new restaurants in Russia this year than last because a fall in the rouble has increased expansion costs and is hurting consumers, its Russian chief executive Khamzat Khasbulatov told Reuters. The rouble, hit by a drop in oil prices and Western sanctions over Ukraine, has fallen more than 50 percent since early 2014, fuelling inflation. Russia now faces its first recession since 2009.
