AUD/USD has had a sharpish fall in past minutes while NZD/USD has been on a slow burn lower from most of the session.
The USD is adding points across the majors board (same old story, rising yields, a hawkish FOMC, risk aversion) - yen, AUD and NZD all notable losers. But CAD and GBP are succumbing also.
EUR/USD has been relatively stable.
Apart from what has already been posted there is no fresh news.
