European Stock Markets Open Lower as Bank Shares Decline

European stocks fell today, Monday, with the STOXX 600 index decreasing by 0.3% after recording its largest percentage loss in three months at the end of a busy week of central bank decisions last Friday. At the same time, the energy sector rose by 0.2% as oil prices increased following a rebellion by Russian mercenaries at the beginning of the week, raising concerns about potential disruptions to Russian oil supplies.
