The GBP/USD extended losses and retested the 1.6160 support area at the beginning of the American session, as the pound weakens across the board.
The GBP/USD broke below the 1.6200 mark and accelerated toward 1.6165, where it bottomed out roughly the same level it did yesterday. At time of writing, GBP/USD is trading at the 1.6175, 0.3% below its opening price, as investors await the ISM services PMI release.
If GBP/USD breaks decisively below 1.6160 next supports could be found at 1.6110 (10-day SMA) and 1.6070 (Sep 23 high). On the other hand, resistances could be faced at 1.6190 (100-hour SMA), 1.6259 (Oct 1 high) and 1.6300 (psychological level).
