USD/JPY 15min Challenge
Past challenge from 2026-03-26. See the correct answer and explanation below.
SCENARIO
USD/JPY is at 151.20. It has been grinding higher in a tight channel for 2 days. The Ministry of Finance (MoF) just issued a verbal warning about "excessive yen weakness" and said they are "watching markets closely." Price dipped 30 pips to 150.90 on the headline but has already recovered to 151.20 within 15 minutes.
Market Context
Japan intervened in the FX market twice in the past 6 months when USD/JPY hit 152. The last intervention caused a 500-pip drop in hours. Current price is 80 pips from the intervention zone.
Key Levels
Central bank verbal warnings near known intervention levels make any long position extremely dangerous. The quick recovery might look bullish, but it brings you closer to the 152 intervention zone where Japan has historically sold dollars aggressively (500+ pip drops in hours). Shorting is also premature -- verbal warnings are not actual intervention. Stay flat until either: (1) intervention happens and you trade the aftermath, or (2) price pulls back to 150 and the intervention risk resets.
Prop Firm Implications
A surprise intervention could trigger a 500-pip move against you in minutes. No FTMO daily loss limit can survive that without proper sizing, and most forex traders are oversized near these levels.
