When the yen weakens quickly, Japanese officials start to speak. Warnings about excessive moves, mentions of readiness to act, and eventually, actual intervention.
The pattern matters for scalpers because the sequence can produce sharp reversals. A long USDJPY position into verbal warnings has a risk of a sudden collapse of several yen in minutes.
The warnings escalate in tone. 'Closely watching' is mild. 'Taking decisive action' is not. Markets learn the vocabulary and react at each step.
Real interventions often occur in thin hours or just after a data release, catching positions off guard. Price can drop 100 pips or more within seconds and then partially recover.
Knowing the context helps. If USDJPY is near multi-year highs and officials are talking, the risk of a violent move against longs is high, and size should reflect it.
A calendar of official speeches, plus a news feed with fast headlines, offers some warning, though not enough to react after the fact.
