FXstreet.com (Barcelona) - GBP/USD jumped about 400 pips after the Fed's release reaching its highest level since the first of March at 1.4335, although the pair has been unable to hold t hose levels and has stepped back towards 1.4180 support level.

At the moment the Pound is setting another upside reaction breaking above Mar 16 high at 1.4235, on its way to 1.4300 (Mar 6 high), and if the pair swings above there, 1.4365/85 would be the level to observe.

On the downside, a correction move could pull the Pound down, below 1.4235, to test intra-day low at 1.4160, and below there, 1.4100 and 1.4060 could be next support levels.
