FXstreet.com (San Francisco) - After printing an inside day in thin holiday trading overnight, the EUR/USD has slipped below the 1.2690 support zone to reach fresh 2-month lows this Tuesday in Asia. Disagreements between the euro zone and the International Monetary Fund over shrinking Greece’s debt are the primary catalyst here, which is weighing on sentiment and EUR. Spot has fallen to as low as 1.2677, stalling at dynamic support in the form of a descending trendline drawn from the peak of Feb 29 to that of April 2. Should the bearish momentum extend, there should be scope for EUR/USD bears to test bids at 1.2635 (Aug 31 high), then circa 1.2605 (50% of the latest bullish run).
