Many Russian have problems to maintain their lifestyle since the Ukrainian crisis. So while the Russians drove up prices in the past by massively invading Monaco and the South of France, they now do the opposite. Spain (Marbella) has the same problem.
On top of that many countries work together to stop the fake living (address in Monaco but living in their home country) of HNW people. It has become much more easy to check where people were or are (check mobile phones, cameras everywhere, airport control, twitter, facebook, creditcards, bankcards...)
Since 2000 the Rouble lost 75% of its value against the EURO. And oil lost over 50%.
