NEW YORK, May 24 (Reuters) - U.S. stocks slid on Monday, driving the Dow to its lowest level since Feb. 10 as fresh signs of Europe's banking problems emerged.
The euro zone's turbulence kept investors wary of taking on risk, after the S&P 500's 4.2 percent drop last week.

Concerns about Europe's banking system continued to weigh on markets, after the Bank of Spain took over a small savings bank, CajaSur, over the weekend, increasing anxiety among investors worried about debt problems spreading throughout financial markets.
"What happens specifically to Greece doesn't matter a whole lot, but if you start spreading to larger countries like Spain, then it becomes an issue. That is what is causing all this right now," said Peter Jankovskis, co-chief investment officer at OakBrook Investments LLC in Lisle, Illinois.
