The rouble touched its weakest since late 2016 before recovering a small part of recent losses as a sell-off of Russian assets, triggered by more US sanctions, extended into Tuesday with the reaction from local authorities still muted.
The United States on Friday imposed sanctions against 17 senior government officials plus seven oligarchs and 12 companies they own or control, sparking an investor exodus.
Designed to punish Moscow for its alleged meddling in the 2016 US presidential election and other "malign activity," their spread far beyond the targeted companies.
The rouble slid to 63.95 versus the dollar, its weakest since early December 2016, and eased to 78.77 against the euro, a level last seen in early April 2016. It later edged up from lows as the price of oil, Russia's main export, rose.
Bonds took a hit as well. Yields on 10-year OFZ treasury bonds, which move inversely to prices, rallied to 7.55 percent, a level was last seen in late 2017.
They came under added pressure from a proposal by two US congressmen to impose sanctions on holders of Russian debt.

"While the general backdrop remains uncertain and the threat of further sanctions is unclear, we believe the Russian market is near a temporary floor," Alfa Bank said in a note.
"We note that the fundamentals surrounding the Russian market remain mostly unchanged and that Russian equities still provide among the healthiest dividend returns globally. We would thus ignore the current jitters and buy into the current weakness, particularly with dividend season almost upon us."
The economic impact of the new sanctions was also unclear and analysts said it was too early to revise forecasts.
"We tend to believe that the impact on economic growth ought to be fairly limited given that Russia has already deleveraged, and economic policies of recent years ensured stabilisation and de-risking of the domestic economy," Renaissance Capital analysts Oleg Kouzmin and Daniel Salter said in a note.
