Seoul shares reversed the previous session's gain on Monday, hurt by the struggle in Washington over the raising of the US debt ceiling, with time running out to avert a default. Ratings agency Moody's also cut Greece's debt ratings by three notches to Ca on Monday, and said the chance of a default is now "virtually 100 percent".
"It is not that US congressmen will not raise the debt ceiling, but that they at odds over detailed plans. They are going to reach a deal in the end," Lee Seung-woo, an analyst at Daewoo Securities, said. "The European debt crisis appears to be nearing an end. The important thing is not whether Greece defaults or not, but whether the international community supports Greece," he said.
