There is arguably just one to take note of on the day, as highlighted in bold below.That being for USD/JPY at the 157.00 level. However, the expiries don't tie to any technical significance and may not have too much impact considering prevailing trading sentiment in broader markets. As traders digest the US-Iran conflict and higher oil prices, the dollar side of the equation is dominating and we're once again seeing slight bids in the dollar today.It's very much the resurgence of the petrodollar trade as outlined here yesterday.That being said, do keep in mind that in this day and age we tend to see markets move on from one major story to another rather quickly. The social media revolution has created an echo chamber of sorts that we tend to become desensitised by the same news and headlines in just a matter of days.As such, markets might be looking to move on quickly from the whole US-Iran conflict unless there is some actual prolonged economic damage. For now, all eyes will stay on the Strait of Hormuz still especially in sizing up how that will impact the oil market and any broader market influences.To stay on the post topic, don't expect much impact from the option expiries on the board in a time like this.For more information on how to use this data, you may refer to this post here.Head on over to investingLive (formerly ForexLive) to get in on the know!
