Back then no one was worried about the fall of the ruble having spillover effect. If Sberbank failed, it wouldn't jump to Europe. Then again, there was little worry about that since the Russians had more than enough in reserves to cover the debts.
With Turkey, however, there is a real worry about this jumping into Europe. From Zerohedge:
Friday's fall came after the Financial Times reported that supervisors at the European Central Bank are concerned about exposure of some of Europe's biggest lenders to Turkey, including chiefly BBVA, UniCredit and BNP Paribas. The FT reported that along with the currency's decline, the ECB's Single Supervisory Mechanism has begun to look more closely at European lenders' links with Turkey. The moves also came after the US showed no signs of lifting crippling sanctions despite the visit of a Turkish delegation to the US capital.
