Russia's ruble has crashed 20% as Ukraine war costs pile up and energy revenue sinks

• Russia's currency is trading at 75 rubles per US dollar, the lowest it has been in 10 months.
• The 20% depreciation since December comes amid falling energy revenues and higher government spending.
• Russia has been selling its reserves of Chinese yuan to help close budget deficits.

Amid a costly war and collapsing energy revenue, the Russian ruble has sunk 20% since December to its lowest in 10 months.

The currency is trading at 75 rubles against the US dollar, down from its peak of 50 in late July and near levels seen before President Vladimir Putin launched the full-scale invasion of Ukraine last February.
