Not sure if the surge is related to the fixing but AUD has pushed up to fresh session highs near 0.9050. Trend highs at 0.9069 are next resistance.
Risk aversion is clearly receding as US equities rebound to breakeven on the day after falling 1% early on. USD/JPY is rallying strongly as well as AUD.
GBP/USD is jumping too, the subject of speculation of significant demand at the 15:00 GMT fixing.
