Bank of Russia: crypto mining boosts ruble; $1 trades just over 80 RUB

On December 20, 2025, Bank of Russia governor Elvira Nabiullina said cryptocurrency mining is among the factors supporting the ruble’s strength. She noted the sector’s gray-market share makes its impact hard to measure. The ruble was a little over 80 per U.S. dollar, after rising above 110 in January and touching around 76 earlier in December.
