Uptrend, consolidating below week high · RSI 66 · price 158.267

Higher lows since Monday; NY-session breakout above 157.98 now holding in a 158.10–158.40 band.

USD/JPY has printed higher lows since Monday's Asia-session low at 156.58, near the weekly open. Tuesday's London-open drop on the reported BoJ rate check held at 156.82. Wednesday's NY-session break above the 157.98 pre-PMI high came on the US PMI beat and carried price to a 158.40 week high. The pair has since consolidated above the ema20 near 158.10, with RSI(14) around 66, short of overbought.

Support: 158.10, 157.98, 156.82

Resistance: 158.40, 159.00

What it said to watch

  • H1 close above the 158.40 week high opens the 159.00 round number; MoF intervention headlines as Japanese desks return from Silver Week could cap follow-through
  • H1 close back below the ema20 at 158.10 and the 157.98 pre-pmi high would mark a failed breakout and expose the fib 61.8 of the Tue–Wed impulse near 157.42
  • A break of the rising lows trendline and the 156.82 tuesday low would end this week's higher-low sequence
  • US Initial Jobless Claims and Hammack/Paulson remarks (Thu 12:30–13:00 UTC) could materially shift this read

22:02 UTC

Uptrend, consolidating below week high · RSI 66 · price 158.296

Higher lows since Monday; PMI breakout above Friday high holding.

USD/JPY has printed higher lows since the 156.58 dip after Monday's open, and Tuesday's London-open flush to the 156.82 swing low was quickly retraced. The hot US flash PMIs then drove a NY-session breakout through the 158.05 friday high, which now lines up with EMA(20) near 158.06. Price is stalling just under the 158.40 week high with RSI(14) in the mid-60s, short of overbought, while Silver Week has thinned Asia-session liquidity.

Support: 158.05, 157.77, 156.82

Resistance: 158.40, 159.00

What it said to watch

  • H1 close back below the 158.05 friday high and EMA(20) would turn the PMI breakout into a false break
  • H1 close above the 158.40 week high opens the 159.00 round number, where MoF intervention rhetoric is likely to intensify
  • Close below the higher-lows trendline (~158.10) and then the 157.77 tue high (38.2% fib) would break the week's higher-lows structure; the 156.82 swing low is the structural pivot
  • Thu: Fed's Williams (08:10 UTC) and US jobless claims (12:30 UTC, f/c 201K) could materially shift this read
  • Rate-check or intervention headlines as Japan returns from Silver Week risk a gap-style yen move

20:01 UTC

Uptrend, pressing three-week highs · RSI 71 · price 158.35

Higher lows since Monday, PMI breakout above Friday high.

Since the weekly open at 156.81 the pair has printed higher lows: 156.58 on Monday, then 156.82 on Tuesday after the Hormuz-driven London-morning drop. Wednesday's Tue-Wed impulse took out the tue high at 157.77, then the strong US PMIs in NY hours pushed it through the fri high at 158.05. Price is now holding above a rising EMA(20), but the move has stalled just under the wed high at 158.40 with RSI(14) near 71.

Support: 158.05, 157.77, 156.82

Resistance: 158.40, 159.53

What it said to watch

  • H1 close back below the fri high at 158.05 would mark the PMI breakout as a false break
  • Sustained trade above the wed high at 158.40 opens the 158.44–159.53 zone, where MoF intervention risk rises toward the zone top
  • Loss of the tue high at 157.77, near the 38.2% fib of the Tue-Wed impulse, would break the EMA(20) pullback rhythm
  • A break of the higher-low line and the tue low at 156.82 would end the higher-low sequence
  • Thu Fedspeak (Williams 08:10 UTC) and Jobless Claims (12:30 UTC) could materially shift this read

19:01 UTC

Uptrend, extended after PMI breakout · RSI 66 · price 158.16

Higher lows since Monday; broke Friday high, fading from week high.

Higher lows each day since the 156.58 week low at Monday's open. Tuesday's London-open drop to 156.82 was fully recovered, and the NY-session US PMI beat drove price through Friday's 158.05 fri high to a 158.40 week high. Price holds above the ema20 near 157.93 with RSI(14) in the mid-60s. The last two hours slipped from the week high back toward the breakout level, with the Tuesday low-to-week-high impulse still intact.

Support: 158.05, 157.93, 157.33

Resistance: 158.40

What it said to watch

  • H1 close back below 158.05 fri high would turn the breakout into a false break
  • Acceptance above the 158.40 week high puts the 158.44–159.53 zone in play, where MoF intervention risk rises
  • Pullbacks holding the ema20 near 157.93 keep the impulse structure intact; 157.61 is the 50% retracement of the Tuesday low-to-week-high impulse
  • Loss of 157.33 wed low and the higher-low trendline would break this week's rising structure
  • Thu jobless claims and Williams/Hammack/Paulson remarks, plus any rate-check headlines, could materially shift this read

17:01 UTC

Uptrend, overbought after breakout · RSI 77 · price 158.378

Higher lows since Monday, Friday's high cleared.

USD/JPY has printed higher lows since Monday's Asia-session low at 156.58, and Tuesday's Hormuz-headline dip to 156.82 held as the base of this week's impulse. The blowout US flash PMIs drove the break through Friday's 158.05 prior high in the first hour of NY, and price now sits at the 158.40 session high. RSI(14) near 77 is overbought and price is stretched well above EMA(20).

Support: 158.05, 157.79, 157.42

Resistance: 158.40, 159.00

What it said to watch

  • An H1 close back below the 158.05 prior high would turn today's breakout into a false break
  • Sustained trade through the 158.40 session high opens the 159.00 psych level, where the digest flags the highest intervention risk
  • The fib 38.2% at 157.79 and the higher lows trendline mark the first retrace reference; failure to hold the fib 61.8% at 157.42 would break the higher-low sequence
  • Fed's Williams (Thu 08:10 UTC) and Jobless Claims (12:30 UTC, f/c 201K) could materially shift this read
  • MoF/BoJ jawboning or rate-check headlines as Tokyo returns from Silver Week could trigger a sharp snapback

13:26 UTC

Uptrend, pressing Friday high · RSI 70 · price 157.914

Higher highs and higher lows since Monday's low.

USDJPY has printed higher highs and higher lows since Monday's 156.58 Asian-session low. Tuesday's London-open drop to 156.82, when oil fell on the Hormuz headline, has been fully reversed. Wednesday's grind through Asia and London, with Tokyo shut for Silver Week, has held above EMA(20) at 157.72 on hawkish-Fed USD demand, lifting RSI(14) to about 70 and leaving price 14 pips under the Friday high at 158.05; the prior cap near 157.50 now sits below as support.

Support: 157.72, 157.50, 156.82

Resistance: 158.05, 158.40

What it said to watch

  • An H1 close above the Friday high at 158.05 extends the higher-high sequence toward the 158.40 intervention zone
  • US flash PMIs at 13:45 UTC and Fed's Barr at 14:05 UTC could materially shift this read
  • Loss of the prior cap at 157.50 (38.2% of the Tuesday rally fib) would weaken the uptrend read
  • A break of the higher-low line and the tue low at 156.82 would undo this week's uptrend structure
  • MoF warnings or rate-check reports as Tokyo reopens could trigger a sharp reversal near 158.05

12:02 UTC

Uptrend, grinding higher · RSI 67 · price 157.923

Series of higher lows since Tuesday's dip, pressing week highs.

Price has climbed from Monday's 156.575 session low in a shallow channel of higher lows, with Tuesday's swing low at 156.82 the last meaningful dip and every pullback since then holding the EMA20 near 157.68. The advance is tracking the hawkish Fed repricing that lifted the dollar to a seven-week high, while the BoJ's dovish hike keeps the yen offered; the NY session drove the latest leg to 157.97, just under the 158.05 prior high. RSI(14) at 67 is firm but not yet at an extreme, consistent with continuation rather than exhaustion at this stage.

Support: 157.68, 157.45, 156.82

Resistance: 158.05, 158.40

What it said to watch

  • Acceptance above the 158.05 prior high opens the 158.40 cap as the next reference
  • Hourly close back below the 157.45 pivot breaks this week's higher lows and neutralises the channel read
  • US flash PMIs at 13:45 GMT plus Fed's Barr at 14:05 GMT can materially reset this structure within the next two bars
  • Intervention headline risk rises the closer spot trades to 158+, which would invalidate the orderly grind

11:02 UTC

Uptrend, grinding higher · RSI 68 · price 157.826

Higher highs and higher lows since Monday's open.

USDJPY has ground higher in every session since Monday's 156.81 open, the only setback a fast 90-pip London slide on Tuesday into the 156.82 tue low on Hormuz reopening headlines, fully recovered by the NY session. Wednesday's London hours cleared the 157.60 tue ceiling and printed a 157.92 week high, with price holding above EMA(20) on each pullback and RSI(14) around 68. The hawkish-Fed dollar bid described in the digest remains the driver, while the 200-dma near 157.45 is the nearest structural floor under the week's channel.

Support: 157.60, 157.45, 156.82

Resistance: 157.92, 158.05, 158.40

What it said to watch

  • US flash PMIs at 13:45 UTC are the immediate risk to this grind — a clear services miss would test the week's higher-low sequence
  • Acceptance above the 158.05 prior high opens the 158.40 cap zone, the area where MoF intervention rhetoric has previously stalled rallies
  • An hourly close back below the 157.45 200-dma would negate the breakout above the tue ceiling and put 156.82 back in focus

10:02 UTC

Uptrend, grinding higher · RSI 69 · price 157.851

Higher highs and higher lows since Tuesday's low.

Price has ground back up through the week to a session high at 157.92, fully unwinding Tuesday's slide to 156.85 that came on the Iran/Hormuz oil headlines, with hawkish Fed commentary and a seven-week-high dollar the driver. Every pullback since has held above EMA(20), which now tracks 157.63, and the higher-low sequence off 157.35 is intact with RSI(14) pressing the upper end of its weekly range near 69. Immediate supply sits at last week's 158.05 prior high, with 158.40 the firm cap above.

Support: 157.63, 157.35, 156.85

Resistance: 157.92, 158.05, 158.40

What it said to watch

  • US flash PMIs at 13:45 UTC and Fed's Barr at 14:05 UTC land inside the next bars and could materially shift this read
  • Acceptance above the 158.05 prior high would put the 158.40 firm cap in play
  • An hourly close back below the 157.35 prior-day low breaks the higher-low sequence
  • Loss of EMA20 at 157.63 would be the first sign this week's grind is stalling
  • MoF intervention or rate-check headlines remain the main two-way gap risk with spot near 158

08:02 UTC

Uptrend, grinding higher · RSI 67 · price 157.742

Higher lows since Tuesday's flush, pressing week high.

The week opened at 156.81 on Monday and has ground up all week on hawkish Fed pricing and a DXY at seven-week highs; the only real setback was a fast ~90-pip flush from 157.77 to 156.85 in yesterday's London session, fully recovered through the NY session and Asian hours. Price is now back at the week high with EMA(20) around 157.52 catching every pullback and RSI(14) near 67 without a fresh divergence. The 157.23 swing low from late NY marks the last higher low in the sequence.

Support: 157.52, 157.23, 156.85

Resistance: 157.77, 158.05

What it said to watch

  • Hourly close above the 157.77 week high opens the path to the 158.05 prior wk high
  • Loss of 157.52 ema20 and then the 157.23 swing low would break the week's higher-low sequence
  • A repeat of yesterday's rejection at 157.77 without follow-through would mark a double top on the week
  • US flash PMIs at 13:45 UTC plus Fed's Barr are the session's main repricing risk
  • Tokyo intervention risk is live above 157.70 and would produce a sharp move back toward 156.85

07:02 UTC

Uptrend, grinding higher on shallow pullbacks · RSI 66 · price 157.742

Higher lows since Monday's open, highs capped below the week high.

Price has climbed in a tight ascending channel since Monday's 156.81 open, with the weekly low at 156.58 never revisited and every dip holding the rising ema20, now near 157.50. Tuesday's NY-hours air pocket to the tue low at 156.85 — the brief JPY bid on Hormuz reopening headlines — was fully recovered inside two bars, leaving a false break below the channel rather than a structural lower low; the hawkish Fed repricing that pushed the dollar to seven-week highs has kept the grind intact through thin Tokyo holiday liquidity. Asia hours today have marked a fresh push to 157.74, right into the week high at 157.77, with RSI(14) at 66 and no divergence yet.

Support: 157.50, 157.33, 156.85

Resistance: 157.77, 158.05

What it said to watch

  • Hourly close above the 157.77 week high extends the channel toward the 158.05 prior high
  • Loss of the wed low at 157.33 breaks the higher-low sequence and puts the ema20 read in question
  • US flash PMIs at 13:45 GMT and Fed's Barr after are the session's main catalysts for this structure
  • Any MoF/BoJ intervention headline near 158 is the most likely source of a sharp break back under 157.00

06:02 UTC

Uptrend, grinding higher lows · RSI 59 · price 157.632

Higher lows since yesterday's spike-low, capped under the week high.

Price has recovered essentially all of yesterday's London-hours air-pocket from 157.77 down to 156.82 — the drop tied to the Iran/Hormuz de-escalation headlines and the associated crude slide — and has since carved a sequence of higher lows back to 157.63, holding above EMA20 through the Asia session. Momentum is constructive but unhurried: RSI(14) is cycling in the 50s-low 60s rather than pushing extremes, and each attempt above 157.55 has been met with supply well short of the 157.77 week high. With Tokyo out for Silver Week, ranges have been compressed, ATR near 16 pips on the hour, and the post-BoJ 'dovish hike' backdrop keeps the yen leg soft.

Support: 157.52, 157.35, 156.82

Resistance: 157.77, 158.05

What it said to watch

  • Acceptance above the 157.77 week high would open the path toward the 158.05 prior high
  • Loss of the 157.35 swing low breaks the higher-low sequence and puts the 156.82 weekly open back in play
  • US flash PMIs at 13:45 UTC plus Fed's Barr at 14:05 UTC are the main scheduled catalysts inside the next session
  • Any MoF/BoJ verbal escalation as Tokyo reopens could invalidate the grind-higher read abruptly

04:02 UTC

Uptrend, grinding higher with shallow pullbacks · RSI 61 · price 157.657

Higher lows since Tuesday's dip, pressing the week high.

Price has climbed in a stair-step fashion since the holiday-thinned Monday open, with every pullback so far holding the rising EMA(20) near 157.47 and RSI(14) cycling 45–65 rather than reaching extremes. The one sharp break lower — the drop to 156.85 into the NY session Tuesday on reports Iran could reopen the Strait of Hormuz — was fully retraced within hours, leaving a clean swing low at 157.23 and a sequence of higher lows into the Asia session. The dovish 7-2 BoJ hike remains the backdrop for JPY underperformance, and the pair is now sitting a few pips under this week's high at 157.77.

Support: 157.47, 157.23, 156.85

Resistance: 157.77, 158.05

What it said to watch

  • An hourly close above the 157.77 week high opens the path toward the 158.05 prior high
  • Failure to hold the 157.23 swing low would break the week's higher-low sequence and put the 156.85 prior low back in play
  • Loss of the EMA(20) at 157.47 on a closing basis would be the first sign the grind is stalling
  • US flash PMIs at 13:45 UTC are the only high-impact print of the session and could materially shift this read
  • Intervention headlines as Tokyo reopens Thursday are a headline risk not visible in the current structure

02:01 UTC

Uptrend, momentum flattening near week highs · RSI 63 · price 157.582

Higher lows since Monday's open, capped by lower highs into Asia.

USDJPY has ground higher since Monday's 156.81 weekly open, with every pullback so far being absorbed at or just above the ema20 and the week low at 156.58 anchoring the sequence of higher lows. Tuesday's NY session push into the prior-day high at 157.775 was rejected sharply — a ~90 pip flush on the Hormuz reopening headline flagged in the digest — but it was fully retraced within hours and thin Silver Week Asia trade has price back at 157.58. RSI(14) sits in the low 60s, and the 158.05 week high remains the cap that the last two sessions have not challenged.

Support: 156.85, 156.58

Resistance: 157.775, 158.05

What it said to watch

  • An hourly close above 157.775 would clear the prior-day high and re-open the 158.05 week high
  • Loss of 156.85 (tue low) would break the higher-low sequence built since Monday
  • US flash S&P Global PMIs at 13:45 GMT are the week's main catalyst and could reprice this read within a few bars
  • Headline MoF intervention risk means upside extension into 158.00+ has been prone to violent, immediate retracement
