European stocks declined for a second day as tension escalated in Crimea, following Ukraine’s change of government.

The Stoxx Europe 600 Index slipped 0.1 percent to 337.53 at 4:30 p.m. in London. The benchmark dropped yesterday as Credit Suisse Group AG dragged banks lower after a person familiar with the matter said that the Securities and Exchange Commission began an investigation into its accounting last year.

“The market is split between a gross amount of liquidity and a serious situation in Crimea, and -- unfortunately -- the Crimea situation will prevail,” Justin Haque, an equity sales trader at Hobart Capital Markets LLP in London, said by telephone. “There was a lot of fizz in this market, so you only needed to have a small geopolitical earthquake, and this is actually not a small problem.”

“Instability in the Ukraine, particularly if there’s Russian intervention, will be taken very badly by markets,” Percival Stanion, the London-based head of the multi-asset group at Baring Asset Management, which manages about $60 billion, said by telephone. “People aren’t worried about Ukraine in its own right, but it would push Russia into the practically un-investable camp.”

In the U.S., Federal Reserve Chair Janet Yellen repeated that the central bank will probably reduce its monthly asset purchases at regular intervals if the labor market continues to improve. She testified before the Senate Banking Committee in Washington today.

A Commerce Department release showed that durable-goods orders dropped 1 percent in January. Economists had predicted the measure would fall 1.7 percent. A Labor Department report showed jobless claims unexpectedly rose by 14,000 to 348,000 last week.
