• Moscow is trying to prop up the slumping ruble, which has shed around a quarter of its value this year.

Russia's government said late Wednesday that it will bring back some currency controls in a bid to revive the ruble, which has shed around a quarter of its value this year as the war in Ukraine rages on.

Exporter companies, including big oil companies, will be required to sell their foreign exchange earnings for rubles on the domestic market, Moscow announced.
