Interbank dealers say that aggressive sales of EUR/GBP from a US investment bank and a Swiss bank helped drag EUR/USD through support at the 1.3525 level. Spot dropped quickly from the 1.3550s to 1.3514 lows.
BIS has been rumored buying dips, as usual.
Broken trendline support at 1.3480 is next for EUR/USD if weakness persists.
