21:04 UTC

Pullback within broader recovery, momentum flat · RSI 49 · price 157.421

Lower highs and lower lows since 159.03, compressing into a 156.38-157.85 range.

The rally from 153.24 topped at the 159.03 swing high, and the pullback since has printed a lower high at 157.85 and a swing low at 156.38. That low held just above the fib 50% of the advance, and price is now pressing the lower-high trendline. Joint US-Japan intervention warnings kept rallies contained this week, while the soft US core PCE was offset by strong growth data. ATR(14) near 49 pips is well below early-month readings, and price is pinned around converging EMA20 and EMA50, a compression that typically precedes a range break.

Support: 156.38, 156.14, 155.33

Resistance: 157.85, 158.40, 159.03

What it said to watch

  • H4 close above the 157.85 lower high breaks the lower-high sequence and the trendline, opening the prior high at 158.40
  • Failure to hold the 156.38 swing low extends the lower-low sequence toward the fib 50% at 156.14 and the prior low at 155.33
  • Tankan at 23:50 UTC tonight, then ISM Manufacturing and Waller at 14:00 UTC Thu, could materially shift this read
  • Any push back toward the 159.03 swing high runs into heightened intervention risk flagged in the yen digest

17:03 UTC

Pullback from 159.03 top, momentum flat · RSI 49 · price 157.28

Lower highs since 159.03 against a flat floor near 156.38.

After rejection at 159.03, USD/JPY has retraced into a 156.38–157.85 consolidation. It is holding near the 38.2% retracement of the 153.24–159.03 rally, while lower highs compress price against the 156.38 swing low. Price is pinned just under the ema20 and EMA50, and ATR(14) has eased to about 50 pips. JPY is firm on intervention fears and the soft US core PCE, while strong US growth data keeps the dollar side supported.

Support: 156.38, 155.33

Resistance: 157.85, 158.40

What it said to watch

  • H4 close below the 156.38 swing low breaks the floor and exposes the 155.33 pullback low
  • H4 close above the 157.85 lower high breaks the lower-highs trendline and puts the 158.40 prior high back in play
  • Tankan at 23:50 UTC and ISM Manufacturing with Fed's Waller tomorrow at 14:00 UTC could materially shift this read
  • Fresh MoF verbal intervention or rate-check headlines could force a break of the consolidation

13:02 UTC

Pullback within broader uptrend, momentum fading · RSI 41 · price 157.041

Lower highs from 159.03 swing high, compressing near 157.

USDJPY has rolled over from the 159.03 swing high. It has printed a lower high at 157.84 while the swing low slipped to 156.38, leaving price compressing around the 157.00 option strike below both EMAs. The pullback is holding the 50-61.8% fib retracement of the 155.33-159.03 leg. ATR(14) near 52 pips is well below the early-month regime, consistent with a tightening range. Intervention warnings from Tokyo are capping rallies, while a firm USD after the ADP beat is cushioning dips.

Support: 156.38, 155.33

Resistance: 157.84, 159.03

What it said to watch

  • H4 close above the 157.84 lower high breaks the lower-high line and reopens the 159.03 swing high
  • Failure to hold the 156.38 swing low extends the lower-low sequence toward the 155.33 prior low
  • US core PCE (f/c 0.3% MoM) lands around the current bar and could decide the direction out of the compression
  • Tankan at 23:50 UTC and any MoF escalation beyond verbal warnings could materially shift this read

10:32 UTC

Pullback within broader uptrend, rolling over · RSI 39 · price 156.933

Lower highs from 159.03, 156.4-157.8 range.

The rally from the 152.89 low topped at the 159.03 swing high. Since then the pair has printed lower highs and lower lows, and now trades below both EMAs with EMA20 crossed under EMA50. Price has been compressing in a 156.38 range low to 157.85 range high band near the 38.2% retracement (156.68), pinned around the 157.00 option strike as US-Japan intervention warnings offset hawkish Fed pricing. ATR(14) has contracted to roughly half its early-window level, a compression that typically precedes a range resolution.

Support: 156.38, 155.96, 155.33

Resistance: 157.85, 159.03

What it said to watch

  • US ADP (12:15 GMT) and core PCE (12:30 GMT) today could break the range; a soft print is the scenario the digest links to yen strength
  • An H4 close below the 156.38 range low confirms a lower-low and exposes the fib 50% at 155.96, then the prior low at 155.33
  • An H4 close above the 157.85 range high and the lower-highs trendline invalidates the pullback read; the 159.03 swing high sits beyond
  • Tankan at 23:50 UTC and any rate-check reports on intervention could shift JPY pricing overnight

09:02 UTC

Pullback within recovery, momentum fading · RSI 41 · price 156.933

Lower highs from 159.03, basing 156.4-157.8 near 38.2% fib.

The mid-month recovery from 152.89 topped at the 159.03 swing high, and price has since printed a sequence of lower highs while holding a 156.4-157.8 range around the 38.2% retracement. Yen strength on escalating intervention warnings after the Bessent-Katayama call keeps supply capping rallies below the ema20, which has slipped under EMA50. ATR(14) has compressed to roughly 52 pips from triple digits early in the month, consistent with a range awaiting a catalyst.

Support: 156.38, 155.96, 155.33

Resistance: 157.30, 157.85, 159.03

What it said to watch

  • US ADP (12:15 UTC) and core PCE (12:30 UTC) today could materially shift this read
  • H4 close below the 156.38 swing low exposes the fib 50% at 155.96 and the prior low at 155.33
  • H4 close above the 157.85 lower high breaks the lower-highs trendline and reopens the 159.03 swing high
  • Reclaim of the ema20 near 157.30 would neutralise the fading-momentum read
  • Tankan tonight 23:50 UTC and any shift from verbal to actual intervention

05:02 UTC

Pullback within recovery, lower highs forming · RSI 41 · price 156.862

Lower highs from 159.03 swing high, testing 38.2% fib.

The recovery from 152.89 topped at the 159.03 swing high, where Trump's yen concern and Tokyo's intervention warnings triggered a rejection. Since then the pair has printed a sequence of lower highs under a falling trendline, capped by the 157.85 lower high. Price is now sitting below the ema20 and EMA50 and is probing the 38.2% fib near 156.68. The latest bar spiked to a 156.38 swing low beneath Monday's 156.50 and closed back above it, a possible false break. ATR(14) near 52 pips is well below early-month levels, so volatility is compressing ahead of event risk.

Support: 156.38, 155.96, 155.30

Resistance: 157.35, 157.85, 159.03

What it said to watch

  • H4 close below the 156.38 swing low confirms a lower low and exposes the fib 50% at 155.96, then range lows near 155.30
  • Recovery back above the ema20 at 157.35 and the 157.85 lower high would break the falling trendline and neutralise the pullback read
  • US ADP and core PCE at 12:15/12:30 UTC today could materially shift this read via Fed October hike odds
  • MoF intervention data (zero vs non-zero) and Tankan at 23:50 UTC Wed are key yen catalysts
  • A move back toward the 159.03 swing high would run into renewed intervention sensitivity

01:02 UTC

Recovery uptrend stalled, correcting below 159 · RSI 49 · price 157.422

Higher lows from 153.24 intact; 156.50-157.85 range.

The rebound from the 152.89 low printed higher lows into the 159.03 swing high. Price then met rejection there as MoF and Washington intervention warnings hit on Friday, and it has retraced toward the 38.2% fib near 156.68. Monday's dip to the 156.50 swing low was bought, and price is now compressing in a 156.50-157.85 range around the 157.00 round number, wedged between EMA20 (~157.55) and EMA50 (~157.27). ATR(14) near 47 pips is less than half the early-month regime, so the pair is coiling rather than trending, with Fed-hike pricing providing a floor under dips.

Support: 157.00, 156.50, 155.96

Resistance: 157.85, 158.40, 159.03

What it said to watch

  • H4 close below the 156.50 swing low breaks the higher-low line and exposes the fib 50% at 155.96
  • H4 close above the 157.85 range top reopens the 158.40 prior pivot and the 159.03 swing high
  • Loss of the 157.00 round number with EMA20 crossing below EMA50 would flip the H4 EMA state
  • US Core PCE and ADP (12:15-12:30 UTC today) plus MoF intervention data could break the compression
  • Tankan at 23:50 UTC is a second catalyst for the yen side of the range
