The Russian rouble has fallen to fresh new lows against the US dollar today (Monday).
The latest fall means that it now costs more than 60 roubles to buy $1. The 60 rouble mark is considered to be a "psychological barrier" for the currency, according to BBC's Moscow correspondent, Steve Rosenberg.
The rouble has lost more than 45% of its value this year as oil prices and Western economic sanctions continue to put a strain on the Russian economy.
It adds to growing problems facing the Russian government including high inflation, high interest rates and weak growth.
