A concern about the economic stability of the Eurozone:

The energy war, coupled with the trade war that has broken out due to the implementation of the sanctions regime against Russia, may result in Europe’s backsliding into a recession next year. We may already be seeing signs of it. On Wednesday, the eurozone PMI (Purchasing Managers Index) hit a fourteen-month low, while France’s continued to contract and Germany’s fell to a fifteen-month low. Meanwhile, a sanctions-induced reduction in oil flows from Russia could further stifle eurozone growth by 1 to 1.5 percentage points in 2015.
