A dealer said investors were concerned about market talk that the crisis could move to Germany.
“So far, exports of cars and industrial machinery to stronger economies in Asia and the US have helped Germany grow, while low unemployment has buoyed consumer spending at home.
“However, those advantages may not be enough for much longer against the undertow from the eurozone crisis,” he said.
Meanwhile, Wall Street remained subdued, awaiting signals from the Federal Reserve about possible help for the economy, another dealer said.
“Investors are waiting on prospects for more economic stimulus from central banks in China and the US and a financial stability plan from the European Central Bank,” he added.
