Greek Banks Face Curbs to Foreign Exchange Trading

Greek banks are increasingly being hampered from trading currencies, one of the most liquid markets, as international dealers cut back credit lines and costs soar, according to people with knowledge of the trades.

International securities firms are curtailing trading with Greece’s major lenders that may expose them to the risk of a default by the nation and the possible use of capital controls to stem outflows from banks, the people said, asking not to be named because they are not authorized to speak publicly.
