All eyes will be focused this morning on Citigroup(C) -- the third big bank to publish first quarter results.
JPMorgan Chase(JPM) shares fell Friday and were slightly lower in premarket trading after the bank reported first quarter revenue that missed expectations. Its earnings were also sharply down compared to the same quarter last year.
Wells Fargo (WFC)also reported earnings Friday, but unlike JPMorgan, its earnings topped analyst expectations.
European markets were all lower in middy trading as investors reacted to the Friday U.S. sell-off and the growing threat of U.S. and European sanctions against Russia.
Russian stocks and the ruble dropped as the continuing strife between Russia and Ukraine ramped up to a fever pitch. Pro-Russian protesters seized a police station in Ukraine and the government threatened to oust them with a "full-scale anti-terrorist operation."
"Even before this, the U.S. and Europe were threatening more sanctions as Russia forces remain amassed on the Ukraine border," wrote currency strategist Marc Chandler in a market report for Brown Brothers Harriman. "The position and weapons of those forces ... is leading NATO to conclude that Putin is seeking the full occupation of Ukraine."
