The AUD/USD weakened slightly Wednesday and fell to a fresh 1-week low, weighed by concerns that US lawmakers will fail to reach a budget deal preventing a government shutdown next week. AUD/USD extended its pullback from 3-month highs scored post-Fed shock and recently printed its lowest in a week at 0.9338 before finding support. At time of writing, AUD/USD is trading at the 0.9355/60 zone, still 0.3% below its opening price ahead of US data, including durable goods orders for August (12:30GMT) and new residential home sales (14:00GMT). In terms of technical levels, if AUD/USD breaks below 0.9338, next supports are seen at 0.9313 (100-day SMA) and 0.9300 (psychological level), while on the flip side, resistances could be found at 0.9375 (10-day SMA), 0.9393 (daily high) and the 0.9400 mark.
