21:02 UTC

Uptrend, momentum slowing near highs · RSI 51 · price 163.507

Higher highs/lows, consolidating below 164.00.

Uptrend intact off the early-window impulse from 160.90, printing a fresh cycle extreme at 163.99 before stalling; price has since coiled in a tight 163.30-163.99 band on a higher-low structure. The latest bar was rejected from 163.90 back to a 163.51 close, the sharpest single-bar range in the window, with the pair pinned near 40-year highs as it awaits tonight's Fed guidance. ATR(14) around 29 pips reflects a steady, non-expanding regime just under the 164.00 handle.

Support: 163.30

Resistance: 163.99

What it said to watch

  • H4 close above 163.99 opens the 164.00 handle, an area drawing intervention risk
  • Failure to hold 163.30 prior-high pivot confirms a lower-low
  • US Core PCE / GDP Thu 12:30 UTC could materially shift this read

21:02 UTC

Uptrend, momentum slowing near 40-yr highs · RSI 54 · price 163.507

Higher lows intact, capped below 164.00.

USDJPY has ground higher through the window to a fresh cycle extreme at 163.99, the weakest yen since 1986, with the 164.00 handle capping the advance. The latest bar rejected off 163.90 down to 163.23 before closing at 163.51, the first meaningful pullback after repeated tests of the highs; higher-low structure remains intact and price sits above EMA50 but slipped back under EMA20. Positioning is pinned to tonight's Fed decision — the genuinely live catalyst for the pair.

Support: 163.30

Resistance: 163.99, 164.00

What it said to watch

  • Repeated tests of the 163.99 cycle high / 164.00 psych level raise MoF intervention odds
  • H4 close below 163.30 prior high would break the higher-low sequence
  • Fed decision tonight plus Thu 12:30 UTC Core PCE/GDP could materially reprice this read

17:01 UTC

Uptrend, testing cycle high · RSI 60 · price 163.862

Higher highs and lows, coiling below 163.99.

Higher-low structure has held since the early-month pullback near 161.28, lifting price into the 40-year high zone at 163.99. Price is now coiling just below that cap with ATR(14) compressing, and both EMAs sit under price on a firm-but-consolidating dollar. The imminent FOMC decision is the dominant driver into the next bars.

Support: 163.30, 162.80

Resistance: 163.99, 164.00

What it said to watch

  • FOMC decision at 18:00 GMT is the live catalyst and can override this structure
  • A clean H4 close above 163.99 opens the 164.00 psych handle where intervention chatter thickens
  • Loss of 163.30 support would break the recent higher-low sequence, exposing 162.80 swing low

17:01 UTC

Uptrend, momentum easing near highs · RSI 57 · price 163.862

Higher highs / higher lows, consolidating below 163.99.

USDJPY has ground higher since the early-month base near 160.48, printing successive higher lows into the 40-year 163.99 extreme, with price now stalling and coiling just beneath that cap. ATR(14) has compressed while EMA20 and EMA50 stay stacked bullish, reflecting a market pinned near cycle highs where intervention risk thickens into the 164.00 handle. The FOMC decision at 18:00 GMT is the dominant near-term catalyst and sits directly under this consolidation.

Support: 163.30, 162.80

Resistance: 163.99, 164.00

What it said to watch

  • FOMC at 18:00 GMT could materially shift this read
  • H4 close above 163.99 opens the path toward the 164.00 handle
  • Loss of 163.30 support puts 162.80 back in focus

13:02 UTC

Uptrend, momentum slowing near cap · RSI 55 · price 163.65

Higher highs/lows, capped below 163.99.

Uptrend intact with higher-lows since the early-month base near 160.90; price has climbed to test the 163.99 cycle high twice and stalled, consolidating in a 163.30-163.99 band. USD held firm into the FOMC on rebuilt hawkish-hike bets, but the 40-yr high is capping and repeated rejections there flag a potential double top. ATR is steady rather than expanding as price coils below the ceiling.

Support: 163.30

Resistance: 163.99, 164.00

What it said to watch

  • H4 close above 163.99 opens the path toward 165
  • Failure to hold 163.30 flags a fade and breaks the range floor
  • FOMC decision + Warsh presser in ~5h could materially shift this read
  • 164.00 handle is a known MoF intervention trigger zone

13:01 UTC

Uptrend, momentum slowing near highs · RSI 57 · price 163.65

Higher highs into 164, consolidating below cycle high.

USDJPY extended its multi-week uptrend to a 163.99 cycle high before stalling, and price is now consolidating in a tight 163.30-163.90 band just under the 164.00 handle. Higher-low structure remains intact off the mid-month 162.20 base, with EMA20 and EMA50 stacked below price. The pause reflects stretched short-Yen positioning meeting the 164 intervention line rather than any structural weakening.

Support: 163.28, 162.20

Resistance: 163.99, 164.00

What it said to watch

  • FOMC decision tonight 18:00 GMT is the immediate driver and could reset this read in one bar
  • A sustained H4 close above 163.99 opens the path toward the 164 handle and intervention risk
  • Failure to hold 163.28 flags a lower-low and unwind from the highs

09:02 UTC

Uptrend, momentum slowing · RSI 52 · price 163.688

Higher highs/lows, consolidating below 164.

Higher-low structure intact since the early-month base near 160.50, with price stalling into the 163.99 cycle high and consolidating just under the 164 handle. The advance reflects a stretched short-yen positioning with intervention fears capping the top; ATR is compressing as the market waits on FOMC. Rejection repeatedly at 163.99 keeps the range capped while EMA20 and EMA50 stay beneath price.

Support: 163.28, 162.80

Resistance: 163.99, 164.00

What it said to watch

  • FOMC statement 18:00 UTC and Powell presser could materially shift this read
  • H4 close above 164.00 handle opens the path toward the ~165 cycle high
  • Failure to hold 163.28 swing low exposes 162.80 support
  • Proximity to 164 raises MoF/BoJ intervention risk

09:01 UTC

Uptrend, momentum slowing near highs · RSI 53 · price 163.688

Higher highs into 164, now ranging below it.

Uptrend intact off the early-month 160.63 low, printing higher highs up to 163.98 before stalling just under the 164.00 handle where intervention risk from Japanese officials caps the top. Price has since consolidated in a 163.28-163.98 band, with the last bar dipping to 163.28 and recovering. A knife-edge FOMC today and BoJ Friday sit directly over this range.

Support: 163.28, 162.80

Resistance: 163.98, 164.00

What it said to watch

  • H4 close above 164.00 opens the path toward the ~165 cycle high and raises intervention risk
  • Failure to hold 163.28 exposes 162.80 support
  • FOMC 18:00 UTC and Powell presser could materially shift this read

05:02 UTC

Uptrend, momentum slowing · RSI 55 · price 163.603

Higher highs/higher lows, stalling under 164.00.

Higher-high/higher-low structure intact since the 161.28 low mid-month, with the last impulse topping at 163.99. Price has since gone flat, consolidating in a tight 163.30-164.00 band just under the 40-year high at 165.00, where intervention risk sits. FOMC today and BoJ Friday are the dominant swing factors into this compression.

Support: 163.30, 162.80, 161.28

Resistance: 163.99, 165.00

What it said to watch

  • H4 close above 163.99 opens the path toward the 165.00 40yr high
  • Failure to hold 163.30 range low exposes the 162.80 support
  • FOMC statement 18:00 UTC could materially shift this read

05:02 UTC

Uptrend, momentum slowing · RSI 52 · price 163.603

Higher highs then flat consolidation below 164.00.

USDJPY broke out of the mid-month 161.50-162.50 range and rallied to 163.98, stalling just under the 164.00 handle — the zone flagged for intervention risk after April/May's record defence. Price has since drifted into a tight consolidation with ATR(14) compressing to ~20 pips, and the last few bars slipped back below EMA20 while holding well above EMA50. The broader higher-low structure remains intact.

Support: 163.45, 162.80

Resistance: 163.98, 164.00, 165.00

What it said to watch

  • FOMC statement 18:00 UTC and Powell/Warsh presser could materially shift this read
  • H4 close above 164.00 opens the path toward the 165.00 40yr high
  • Loss of the 163.45 range low exposes 162.80 support

01:02 UTC

Uptrend, momentum slowing · RSI 58 · price 163.862

Higher highs/lows, coiling below 164.00.

USD/JPY has held a clean higher-high, higher-low sequence since the early-month base near 160.90, with the dollar reclaiming YTD highs on hawkish-Fed positioning. Price has stalled just under the 164.00 handle for the past week, ATR(14) compressing into the highs as the pair coils below the intervention-sensitive 165.00 zone. Both EMAs sit beneath price, keeping the swing structure constructive but flattening near resistance.

Support: 163.30

Resistance: 164.00, 165.00

What it said to watch

  • H4 close above 164.00 opens the path toward 165.00
  • Failure to hold 163.30 would break the recent consolidation floor
  • FOMC decision today 18:00 UTC could materially shift this read; BoJ Fri is the JPY-side risk

01:02 UTC

Uptrend, momentum slowing below 164.00 · RSI 61 · price 163.862

Higher highs/lows, consolidating under prior swing high.

USDJPY holds a clean higher-high/higher-low sequence since the early-month base near 160.90, but the advance has stalled just under the 164.00 handle after tagging 163.98 twice. Price is coiling in a tight 163.32-163.98 band with JPY pinned near 40-year lows, and ATR(14) has compressed as the range narrows. The read hinges on today's FOMC and Friday's BoJ, either of which can resolve the compression.

Support: 163.32, 162.80

Resistance: 164.00, 163.98, 165.00

What it said to watch

  • H4 close above 164.00 opens the path toward the 165.00 40yr high
  • Failure to hold 163.32 confirms a lower-low toward 162.80
  • FOMC decision today 18:00 UTC could materially shift this read
  • BoJ Friday is the offsetting JPY-side risk into the range
