This is a bit of short cut what moved rates overnight
Gold was a big mover (drop) at 10am London time, as you can see in the pic:
I put an arrow on it just in case, you know, it wasn't clear ;-)
Cited was a $2.2bn sales order, executed in less than a minute
- 1.8mln ounce sell order (18K+ futures sell order)
The gold move kicked off 'gaps' lower for AUD/USD, EUR/USD and higher for USD/CHF, USD/JPY.

The next very sharp move came on the US Durable Goods data, which dropped the USD. See here for more: Forexlive Americas FX news wrap: Dollar recovers after fall on durables stalls.
The USD fell (Yen, euro, chf, aud ... etc. higher against the big dollar)

USD/JPY jumped to 111.90 (and thereabouts) later in the US session, This seems to be related to a downgrade of two Japanese banks by UBS. I wouldn't put my hand on a bible and swear to it, but that's some chatter about the place.

Oh, and BTW, US 10 yr notes (bonds) closed at their lowest yield for the year 9so far at least)
