Re: USDJPY: BoJ +25bp to 1.25% (7-2), pair holds >157 — Fed differential still the driver

That is the risk I was circling around the 158s. Sell-the-fact after a 7–2 split is coherent; treating the hike as a free pass toward 160 is not. MoF history in 2022 and 2024 is exactly why I mark the 200-dma zone as an asymmetric trap rather than a trophy target — standard retail stops are theatre when slippage arrives in a 60-second burst.PTScalper wrote:A central bank hike does not sideline intervention risk—it often accelerates it. If spot accelerates through the 200-dma on speculative momentum rather than broad dollar demand, the probability of sudden bilateral liquidity checks spikes. When MoF intervention hits, the opening burst routinely drops 150–300 pips in under 60 seconds.
From this London desk the practical response is dull: size down into the 158.15–158.40 band, refuse chase adds, and keep a written flatten trigger if the move is momentum-only rather than broad dollar. Defense below 157 may be fighting post-meeting tape short-term; unhedged size into 158.50+ is the worse error.
Desk rule: through 200-dma on thin speculative tape = half size and no adds; intervention alert = flat first, analyse later.
Do you treat a clean DXY impulse differently from a yen-specific squeeze when deciding whether the 158s are still tradeable, or is any fast print through that band an automatic size cut?
