The USD/JPY pair is flashing red warning lights as price action overheats too much. The best evidence is the Relative Strength Index (RSI), which is close to overbought conditions in the daily chart, while the magic 160.00 level, where Japanese authorities intervened last time, is very near. Do not expect a snap reaction immediately, as authorities will want to see if US data on Thursday and Friday could trigger some easing without sticking their neck out and intervening. At max, 163.00 on the upside could be tested on stronger US data in the coming days, while on the downside, that 151.95 level is again the pivotal support to watch.
