Anyone wondering about Ruble's next move from here:
should take a look at the third chart here: http://trueeconomics.blogspot.ie/2015/12/301215-2016-better-be-kinder-to-old.html.
As oil stays around USD35 mark, the duration of slump will be weighing on Ruble, with oil/USDRUB spread compressing on re-valuations of the Russian budget and fiscal position. Current spread appears moderately optimistic to me...
As an aside, c Рождеством!
