The EUR/USD pair attracts some follow-through selling for the second straight day on Wednesday and drops to a one-week low during the Asian session. Spot prices, however, rebound a few pips from the 1.1300 neighborhood and currently trade around the 1.1380 region, still down over 0.35% for the day.

The US Dollar (USD) builds on the overnight bounce from the vicinity of a three-year low touched on Monday and turns out to be a key factor exerting downward pressure on the EUR/USD pair. That said, the weakening confidence in the US economy, along with the prospects for more aggressive policy easing by the Federal Reserve (Fed) and the risk-on impulse, caps gains for the safe-haven buck and helps limit losses for the currency pair.

The European Central Bank (ECB) in Frankfurt, Germany, is the reserve bank for the Eurozone. The ECB sets interest rates and manages monetary policy. The ECB's primary mandate is to maintain price stability, which means either controlling inflation or stimulating growth. Its primary tool is the raising or lowering of interest rates. Relatively high interest rates or the expectation of higher rates will usually benefit the Euro and vice versa. The ECB Governing Council makes monetary policy decisions at meetings held eight times a year. Decisions are made by heads of the Eurozone national banks and six permanent members, including the President of the ECB, Christine Lagarde.
Data releases gauge the health of the economy and can impact on the Euro. Indicators such as GDP, Manufacturing and Services PMIs, employment, and consumer sentiment surveys can all influence the direction of the single currency. A strong economy is good for the Euro. Not only does it attract more foreign investment but it may encourage the ECB to put up interest rates, which will directly strengthen the Euro. Otherwise, if economic data is weak, the Euro is likely to fall. Economic data for the four largest economies in the euro area (Germany, France, Italy and Spain) are especially significant, as they account for 75% of the Eurozone's economy.
