The USDRUB has indeed moved higher (lower ruble) on the back of the Russian escalation and expectations that an invasion is imminent.
Looking at the daily chart the price rise has seen the price move up from 74.94 at the close yesterday to the current price of 77.36. The high reached 77.15.
The high is still well below the high for the year from January 26 which reached 80.415. That was the highest level since November 2020.
So although there is a more imminent threat of a invasion, the markets have reacted by selling the ruble (buying the USDRUB), but the move is still within the high to low range for the year.
Of note technically, is the low reached this week did stall right near the lows from January 2022. The January lows reached 74.17 to 74.276. The low price reached just yesterday bottomed at 74.258 between those lows. .
