AUD/USD struggled a little on the topside in Asia after running into a truck load of selling interests above 0.9360. The pair topped out at 0.9366 then drifted off to a low of 0.9330; last at 0.9340. Traders say option related sell orders above 0.9375 are reportedly protecting an option barrier at 0.9400. This barrier is supposedly very large and will be protected. On the downside unfulfilled bids remain in the 0.9300/20 area. With the market firmly in a “risk on” mood, especially in the US and Asia, we suspect that the barrier at 94 cents will be eventually triggered. The years high is at 0.9407 which if broken is likely to further stoke AUD demand.
