21:02 UTC

Uptrend broken, sharp reversal down · RSI 28 · price 159.348

Vertical breakdown from range highs.

USD/JPY was pinned just under the 163.99 multi-decade high, printing a double top near 163.9 before collapsing roughly 500 pips in two bars to 157.956 and closing at 159.348 — a classic yen snap-back as BoJ/intervention risk detonated after weeks of grind higher. The multi-week uptrend and its range floor near 163.5 are decisively broken, with price now far below EMA20 and EMA50 and RSI deeply oversold. This is the largest single-bar move in the window by an order of magnitude.

Support: 157.956

Resistance: 162.947, 163.50, 163.99

What it said to watch

  • H4 reclaim above 162.947 would negate the breakdown
  • BoJ decision Fri 03:00 GMT — main JPY catalyst for this read
  • Tokyo CPI tonight 23:30 GMT could extend the yen bid
  • Failure to hold 157.956 confirms lower-low extension

21:02 UTC

Sharp reversal lower, downside momentum · RSI 22 · price 159.348

Range breakdown from the 163.5-164 top.

Price ground sideways for two weeks capped by the 163.9-164 multi-decade high, then collapsed nearly 500 pips in a single H4 bar to a 157.96 low before closing at 159.35 — a violent yen snap-back consistent with the BoJ/intervention risk flagged around 163.99. The move sliced clean through the 162.29 range floor and both EMAs, leaving structure firmly broken and RSI deeply oversold. Price is now consolidating just above the sweep low with ATR(14) blown out to ~77 pips.

Support: 157.956

Resistance: 162.288

What it said to watch

  • H4 close back above 162.29 would negate the breakdown
  • BoJ decision and Tokyo CPI overnight could sharply shift this read
  • Loss of the 157.96 sweep low extends the decline

17:02 UTC

Uptrend broken, sharp reversal · RSI 15 · price 159.468

Multi-decade high rejected, breakdown.

The final H4 bar collapsed roughly 500 pips from ~162.95 to a low of 157.96 before closing at 159.47 — a violent unwind of yen shorts after weeks pinned near multi-decade highs, consistent with the intervention/BoJ-tone risk flagged in the digest. This shatters the prior uptrend: price now sits far below EMA20/50 with RSI deeply oversold. The long lower wick into 157.96 shows demand stepping in on the flush.

Support: 157.956, 159.00

Resistance: 162.947

What it said to watch

  • Tokyo CPI tonight (23:30 UTC) and BoJ decision Fri (03:00 UTC) are major catalysts that could reshape this read
  • Recovery back above 162.947 (prior close) would repair much of the breakdown
  • Failure to hold above 159.00 opens a retest of the 157.96 bar low

17:02 UTC

Sharp reversal off cycle highs · RSI 25 · price 159.468

Violent break below multi-week range near 164.

After weeks pinned near multi-decade highs, USDJPY carved a double top around 163.99 and the latest H4 bar collapsed roughly 500 pips to 157.956 before closing at 159.468 — a violent rejection of the highs into tonight's Tokyo CPI and Friday's BoJ. ATR(14) has exploded to ~70 pips as the compression near the top gave way, and RSI is deeply oversold. Price now sits well below both EMA20 and EMA50 after the break.

Support: 157.96, 158.00

Resistance: 162.95, 163.99

What it said to watch

  • Tokyo CPI 23:30 UTC and BoJ decision Fri 03:00 UTC could materially shift this read
  • Reclaim of 162.95 would suggest the drop was a spike rather than a trend change
  • Failure to hold 158.00 psych opens continuation below the 157.96 swing low

13:02 UTC

Uptrend, sharp rejection at highs · RSI 47 · price 162.909

Higher highs into multi-decade high, latest bar reversing.

A multi-week uptrend carried USD/JPY to a fresh multi-decade high at 163.99 before the latest H4 bar printed a sharp ~137-pip rejection back to 162.90, dropping price below both EMA20 and EMA50 for the first time in the window as ATR expanded. The rally had stretched into the 163.50-163.99 zone where MoF/BoJ intervention risk is repeatedly flagged. Momentum divergence had been building as new highs met flatter RSI.

Support: 162.29, 162.00

Resistance: 163.50, 163.99

What it said to watch

  • H4 close back above 163.50 neutralises the rejection and reopens the 163.99 high
  • Failure to hold 162.29 exposes the 162.00 round number
  • Tokyo CPI (23:30 UTC) and BoJ decision Fri could reset this read

13:01 UTC

Uptrend, momentum stalling at highs · RSI 46 · price 162.909

Higher highs into 163.99, sharp rejection off the top.

Multi-week uptrend printed higher highs into the 163.99 multi-decade high, but the latest bar delivered a ~137-pip rejection back to 162.91, dropping price under the EMA20 for the first time in the run. Twin tests near 163.90-163.99 leave a double-top look with intervention risk elevated this close to the record. The reversal comes ahead of Tokyo CPI and the BoJ decision, the near-term levers for JPY.

Support: 162.05

Resistance: 163.50, 163.90, 163.99

What it said to watch

  • H4 close below 162.05 confirms a lower low and breaks the higher-low sequence
  • Reclaim of 163.50 EMA20 keeps the uptrend structure intact
  • BoJ decision and Tokyo CPI in the next session could materially shift this read
  • Proximity to 163.99 keeps MoF/BoJ intervention risk in play

09:02 UTC

Uptrend, momentum flattening near highs · RSI 57 · price 163.725

Higher highs/lows, consolidating below 40yr high.

Higher-high, higher-low structure intact since the early-month base near 161.60; the mid-window impulse to the 40-year high at 163.99 has since given way to a tight consolidation between 163.30 and 163.90 as USD/JPY pins near multi-decade highs on the wide US-Japan rate gap. ATR(14) has compressed inside this range, and price holds above both EMA20 and EMA50. Proximity to the 163.99 high keeps MoF/BoJ intervention risk elevated.

Support: 163.30

Resistance: 163.99, 163.90

What it said to watch

  • H4 close above 163.99 extends the uptrend but sits at the intervention-risk 40yr high
  • Failure to hold the 163.30 pivot signals a deeper pullback
  • Tokyo CPI 23:30 UTC and BoJ Friday could materially shift this read

09:02 UTC

Uptrend, momentum slowing near highs · RSI 58 · price 163.725

Higher highs/lows, consolidating below 40yr high.

Uptrend intact with higher highs and lows since the early-month base near 161.00; price is consolidating just below the 163.99 40-year high after the hawkish-Fed lift kept the yen pinned. ATR near 41 pips shows steady, non-compressing conditions, with repeated stalls at 163.90-164.00 marking the ceiling and 163.30 holding as the pivot on dips.

Support: 163.30

Resistance: 163.99, 163.90

What it said to watch

  • H4 close above 163.99 extends the multi-decade high
  • Loss of 163.30 pivot breaks the higher-low sequence
  • Tokyo CPI tonight and BoJ Friday could materially shift this read

05:01 UTC

Uptrend, momentum slowing · RSI 52 · price 163.497

Higher-lows intact, consolidating below cycle high.

Uptrend intact with a clean run of higher-lows since the early-month 161.28 base; price is now pinned in consolidation just below the 163.99 cycle high and the 164.00 handle. ATR(14) sits in a moderate regime as the tape coils under resistance, with the Yen failing to catch a bid near 40-year lows. Tokyo CPI tonight and Friday's BoJ decision are the dominant near-term catalysts.

Support: 163.30, 162.20

Resistance: 164.00, 163.99, 163.90

What it said to watch

  • H4 close above 164.00 opens continuation past the 163.99 cycle high
  • Failure to hold the 163.30 floor signals a deeper pullback toward 162.20
  • Tokyo CPI at 23:30 UTC and BoJ Friday could materially shift this read

01:02 UTC

Uptrend, momentum slowing · RSI 52 · price 163.264

Higher highs / higher lows, pulling back from cycle high.

Uptrend intact — higher highs and higher lows since the early-month 161.28 low, printing a fresh cycle high at 163.99. The latest H4 rejected off that high and pulled back to the 163.30 support shelf, with ATR still elevated on the run into new highs. Thursday's US Core PCE and Friday's BoJ decision are the near-term catalysts.

Support: 163.30, 162.72

Resistance: 163.99, 164.00

What it said to watch

  • H4 close below the 163.30 support shelf opens the path toward the 162.72 prior high
  • A clean break above the 163.99 cycle high risks MoF intervention near the 164.00 handle
  • US Core PCE Thu 12:30 GMT and BoJ Fri could materially shift this read

01:01 UTC

Uptrend, momentum slowing near highs · RSI 51 · price 163.264

Higher highs/higher lows, capped at 163.90-164.00.

Uptrend intact off the early-month 160.90 low, with a steady sequence of higher lows carrying price to a 163.99 cycle high — a 1986-era peak. Multiple rejections in the 163.90-164.00 zone have stalled the advance, and price is now consolidating on the 163.23 shelf just below the EMA20. JPY has stayed weak into a fully-priced BoJ hold, leaving cycle-high resistance the pivotal structure.

Support: 163.23, 162.99

Resistance: 163.90, 164.00

What it said to watch

  • H4 close above 163.90 opens a retest of the 164.00 handle and invites MoF intervention risk
  • Loss of the 163.23 shelf exposes 162.99 and threatens the higher-low sequence
  • Tokyo CPI tonight and BoJ Friday are cross-JPY catalysts that could reset this read
  • US Core PCE/GDP Thu 12:30 GMT could shift USD leg of the pair
