The companies, which account for 20 percent of all oil produced in Tatarstan, say current oil prices -- which are at a four-year low -- do not even cover their tax obligations. They are asking to be excused from paying export duties and production taxes until prices go back up.
Tatarstan's little oil rebellion is just the latest example of how the global financial crisis -- and the falling commodities prices that have accompanied it -- is sending tremors through Russia's fragile social contract.
In October, the truck manufacturer Kamaz, moved to a four-day work week due to the crisis. And this week the company told its employees to take a mandatory two-week holiday, for which they will receive two-thirds of their wages.
And in a sign that things could really get dicey soon, the crisis is now taking its toll on Russia's gilded bureaucratic class. The ruling Unified Russia party announced on November 21 that it was cutting 25 percent of its party functionaries.
Easy oil money has long been the glue that held Russia's "managed democracy" in place. What will happen when the cash begins to dry up?
