The greenback rebounded from an 8-month low against the Japanese yen on Wednesday, as upbeat U.S. data prompted investors to unwind short positions in dollar.

Although the greenback fell below Tuesday's low of 85.67 against the Japanese yen in Asia to a fresh 8-month low of 85.32 on risk aversions after triggering stops at 85.50 and traded narrowly in Europe, dollar rebounded strongly in NY opening after the release of better-than-expected U.S. employment and services data, which prompted investors to unwind short positions in the greenback, and then the pair hit an intra-day high of 86.39 before trading narrowly in NY afternoon.

Later, although euro rebounded to 1.3233 ahead of NY opening after EU retail sales data, the single currency tumbled to an intra-day low of 1.3131 due to upbeat U.S. employment and services data before recovering.

German services PMI fell to 56.5 in July versus economists' forecast of 57.3. EU services PMI in July also came in lower-than-expected at 55.8 against the expectations of 56.0.

EU retail sales in July came in at 0.0% m/m and 0.4% y/y, versus the economists' forecast of 0.1% m/m and 0.1% y/y respectively.

Later, although cable managed to rebound to 1.5961 in NY opening, sterling fell again in tandem with euro and hit an intra-day low of 1.5857 before stabilising.
