Comments from Eurogroup president Jean-Claude Juncker, raising doubts over an IMF disbursement of financial support to Greece in June, put markets on edge, with the Dow and S&P 500 stock indices briefly adding to losses and U.S. bonds adding to gains after the news.
Gold prices also fell, led by a fall in euro-priced bullion.
Investor desire to own stocks, commodities, and other risky assets remains fragile as U.S. economic growth shows signs of slowing further and European policy-makers deal with the persistent debt problems in Greece, Portugal and Ireland.
