Market optimism rises as bank stocks soar and volatility subsides.

European stock markets opened higher as investors hope recent market volatility has come to an end. The pan-European Stoxx 600 index was up 0.5% in early trade, with most sectors posting gains. Banks were up 1.3%, with Credit Suisse moving 2.1% higher. Policymakers and central bank officials have continued to stress the banking system is not heading for a crash, though jitters remain. Bitcoin and ether fell roughly 3% in Asia's morning trade after US officials filed a complaint against crypto exchange Binance and its co-founder Changpeng Zhao.
