The Dollar came roaring back yesterday against its rivals as poor housing data and falling equity markets sapped traders appetite for risk. Existing home sales numbers were released to an unspectacular reception with the numbers failing to reach their expected targets. Only 5.10M existing homes were sold as compared with economists forecasts of 5.36M. This sent traders running from higher-yielding currencies and into long Dollar positions.

Yesterday's trading was notably volatile, with the EUR/USD climbing in early European trading hours to a daily high of 1.4789, only to end the day at 1.4650 from 1.4721. Driving the early appreciation for the EUR was a lower number of U.S. Unemployment Claims. These gains were later eroded after less than spectacular housing data was released. Against the Yen the Dollar was down as traders looked for the less risky currency. The pair closed at 90.82 from 91.30.

Looking ahead to today's trading, we can expect further volatility of the Dollar. The Group of Twenty (G20) meets for a second day today. Comments made by the global heads of finance can move the market fast so traders should be aware of their impact. U.S. New Home Sales data is due at 2:00pm GMT time. If the New Home Sales is anything like the Existing Homes Sales data from yesterday, the EUR/USD could continue its decline for the second day in a row to finish the week near the 1.4550 mark.
