21:01 UTC
Uptrend, momentum stalling near range top · RSI 58 · price 159.249
Higher-highs since 155.03, capped under 159.65.
Trend remains constructive with higher-lows from the 155.03 spike low and a string of higher-highs into 159.65, but the latest push tagged a fresh swing high on softer momentum, leaving a bearish RSI divergence into the range top. Price stalled after US-Iran truce headlines pressured the dollar, and the wedge-like compression along the rising lower trendline is tightening. EMA20 and EMA50 still under price, keeping the structural bid intact for now.
Support: 158.79
Resistance: 159.65

H4 close below 158.79 swing low breaks the rising sequence
Break and hold above 159.65 swing high extends the uptrend

Uptrend, momentum slowing near range top · RSI 60 · price 159.299
Higher highs and higher lows, capped at 159.65.
USDJPY has ground higher for three weeks from the 155.00 area, printing successive higher lows with the latest at 158.59 and now coiling just under the 159.65 range top. Price action has narrowed into a rising wedge with shrinking ATR(14), consistent with consolidation rather than fresh impulse, though both EMA20 and EMA50 remain below price. Ceasefire-related USD softness this session has been absorbed at the psych 159.00 level so far.
Support: 159.00, 158.59
Resistance: 159.65, 160.00
What it said to watch
H4 close above 159.65 opens the path toward the 160.00 round number
Loss of 159.00 psych exposes the 158.59 swing low
Failure at 158.59 breaks the higher-low sequence
US/Iran MOU headlines could materially shift this read
Higher highs and higher lows, grinding into range top.
Multi-week uptrend intact with higher-lows stacking from the 155.03 spike low through 156.30 and 158.79. Price is grinding into the 159.50-159.65 area with narrowing daily ranges and ATR compression, a rising-wedge feel as momentum slows just shy of the 160.00 psych level. PCE landed in line this session, removing the immediate USD catalyst and leaving structure to dictate the next leg.
Support: 158.79, 156.30
Resistance: 159.65, 160.00
What it said to watch
Sustained H4 close above 159.65 opens the path toward the 160.00 psych level
Loss of 158.79 swing low would break the higher-low sequence
BoJ intervention risk noted in news flow near these levels could materially shift the read

Uptrend, grinding higher · RSI 64 · price 159.465
Higher highs / higher lows since 155.03 swing low.
Clean higher-low structure since the 155.03 spike low three weeks ago, with price stair-stepping through the 157.50 and 158.60 prior ranges. The latest leg has cleared the 159.18 swing high and is pressing the 159.65 area, with EMA20 and EMA50 stacked beneath price. ATR(14) around 28 pips is steady rather than expanding — a measured drift higher rather than an impulsive breakout.
Support: 159.00, 158.59, 157.51
Resistance: 159.65, 159.95
What it said to watch
H4 close above 159.65 opens the path to the 159.95 round number
Loss of the 159.00 psych pivot would be the first sign of momentum fading
Close back below 158.59 swing low invalidates the higher-low sequence
US-Iran Hormuz escalation headlines could pull JPY bid back and disrupt the read
05:00 UTC
Uptrend, momentum steady · RSI 65 · price 159.605
Higher highs and higher lows since mid-window low.
USDJPY is grinding higher with a clean sequence of higher highs and higher lows since the 155.03 spike low earlier in the window, and price has now cleared the 159.20-159.35 shelf to print a four-week high at 159.65. EMA20 and EMA50 are stacked bullishly underneath, and ATR(14) sits in a moderate regime — momentum is steady rather than blow-off, with the round 160.00 level the next obvious magnet. Hormuz risk and JGB-led fiscal jitters are providing the macro backdrop into this push.
Support: 159.20, 158.65
Resistance: 159.65, 160.00, 160.72
What it said to watch
H4 close above 160.00 round number opens path toward the 160.72 window high
Rejection at 159.65 session high and reclaim below 159.20 prior breakout would neutralise the uptrend read
Loss of 158.65 swing low confirms a lower-low and breaks the higher-low sequence
Headline-driven intervention risk from MoF given proximity to multi-week highs

Uptrend, momentum slowing near range high · RSI 64 · price 159.576
Higher-lows since 155.03 base, capped at 159.58.
Price has ground higher in a tight ascending channel since the 155.03 base earlier in the month, posting clean higher-lows around 156.30, 157.50 and 158.65. Compression into the 159.58 range high with ATR(14) ticking down points to a rising wedge structure; RSI in the mid-60s shows momentum holding but not extending. Carry-trade flows referenced in the wires are consistent with the persistent demand seen on every dip.
Support: 159.00, 158.65, 157.60
Resistance: 159.58, 160.30
What it said to watch
H4 close above 159.58 range high opens path to 160.30 prior high
Loss of the 159.00 swing pivot would break the wedge and expose ema50 near 157.60
BoJ/MoF intervention headlines remain a tail risk given the carry-trade framing in news flow
