[CME: USD/JPY approaches 155 yen, where a large number of options are located] On September 3, CME Group (CME) stated that as options to sell the U.S. dollar were triggered, the yen's rise accelerated, and if it exceeded 155, it may trigger more U.S. dollar selling, because the market demand for options with a strike price of 155 yen has continued to increase throughout the day. The derivatives market operator said the most actively traded on Thursday were overnight dollar put options with a strike price of 155.0 yen. USD/JPY fell as much as 2.1% to 155.34, the lowest since August 3. If it falls below 155.23, USD/JPY will fall below the level hit during the latest round of yen-buying intervention; many in the market believe that 155 is a key yen resistance level because Japan failed to push the yen above this level when it intervened in the market in April. After USD/JPY fell below 156.25, the market's interest in the 155 execution price increased; CME said that the 156.25 execution price also attracted strong demand earlier in the day.
