As Russia's economy continues to struggle amid swingeing sanctions, oil price declines, a weak ruble and rampant inflation, ordinary Russians are feeling the pinch - with some believing the crisis hasn't even started yet. Russia's economy has been hit hard by the severe decline in global oil prices and sanctions imposed on the country for its part in the Ukraine conflict. This, in turn, has caused the currency to weaken 90 percent against the dollar over the last 12 months, further pushing up the rate of inflation which stands around 11.4 percent. To top it all off, Russia's economy is expected to enter recession this year, but one Moscow-based economist told CNBC that the crisis hadn't even started yet. "We are on the edge of crisis, we're close but we're not yet there," Vladimir Tikhomirov, chief economist at Russian financial services firm BCS Financial Group, told CNBC. "I can say that we have not yet seen the full effect of the economic crisis - redundancies, closing businesses, rising non-performing loans - we haven't seen those things yet but that's not to say it's not coming," he warned.

Russia's economy has undergone a radical tranformation from the days when it was a jewel among emerging markets. In 2015, the economy could shrink by as much as 5.5 percent, however, according to ratings agency Moody's, a far cry from the 5.6 percent growth seen back in 2008.

Against such a backdrop of shrinking growth, Russian businesses are nervous, Tikhomirov warned, although he said that they were largely powerless to change both external factors - such as the oil price decline or global slowdown -- and internal factors such as President Vladimir Putin. "The business world is worried and concerned. It's a very challenging situation to put it mildly but a lot of the risks are not in the economy are in politics and geo-politics and that has an effect on the prospects of doing business in Russia." "Generally, the business sector cannot do much about that -- there's not much influence they can have on politicians," he said. Self-employed Stanislav Sergeev, who works with start-ups in Moscow and St Petersburg, says he currently has no work now and that he and other business owners are worried.

Some of my friends who are owners of businesses have started to reduce the amount of employers by 50 percent and to reduce their income by 70 percent," Sergeev told CNBC Thursday.

He said that Russians were having to spend more of their money because of the devaluation in the ruble and warned that as the domestic market starts to collapse, and as more people become unemployed, "Therefore we expect a rise in criminality." Russia's leaders have been keen to absolve themselves of responsibility for the economic crisis, blaming the decline in oil and "external factors," as Putin called them, for the crisis. That Russia needs to change is already recognised by the country's government, however.

Russia's Finance Minister Anton Siluanov told CNBC last week that reforms were desperately needed in order for Russia to recover, recognizing himself that the country was in "dire straits" economically.

He added that reforms designed to move Russia away from its reliance on oil were also slow moving. "Reforms are spoken of but little is done...Today Russia has a developed financial sector, automotive sector and these are sectors that have seen progress but the economy is still largely commodity driven and this needs to change." The depth of the crisis depended on two factors, Tikhomirov said: whether the oil price recovers and whether there was a peaceful solution to Ukraine conflict. Russia has had sanctions imposed on its economy for almost a year by the west for its incursions into Ukraine, which have added to its economic downturn.
