Hot US CPI Drives USDJPY to 158.96, Testing the 159.00 Range Top

USDJPY climbed to 158.96 in Asian trading on November 11, its highest level since September 24, after US inflation data landed hotter than expected and pushed the pair right up against the 159.00 top of a seven-week range. At 07:06 UTC the pair traded at 158.76, according to the TradingView analysis by AetherEdge that anchors this piece.

The catalyst was the October US CPI report. Headline inflation rose 0.4% month-over-month against a 0.3% expectation, while core came in at 0.3% versus 0.2% forecast, as reported by CNBC. The dollar index moved to 102.26 and the US 2-year yield jumped roughly 18 basis points, per Reuters. USDJPY rose to about 158.80 on the release.

What does the chart show?

The pair has traded sideways between roughly 156.10 and 159.00 since late September, with range highs at 158.99 on September 23 and 158.94 on October 13. But the floor keeps rising. Daily lows printed at 156.07 on October 23, 156.96 on October 30, 157.25 on November 5 and 157.66 on November 9.

Rising lows into a flat top form an ascending triangle on the daily chart. A rising 4H trendline drawn from the October 23 low at 156.07 through the November 5 low at 157.25 now sits near 157.70.

The key levels:

• Resistance: 159.00 (the range top), then 160.00 — a round number and an intervention-sensitive zone, with 159.72–159.86 in between.
• Support: 158.35 (the October 28 and November 9 highs, now the breakout shelf), the trendline near 157.70, and then 157.25 (the November 5 low).

In plain words: the market has coiled into a narrowing triangle pointed straight at the range top, and the CPI print just supplied the pressure.

How did the Fed odds shift?

Sharply. CME FedWatch now prices roughly a 92% probability of a 25-basis-point Fed hike on December 9 and about 9% for 50 basis points, with no probability of a hold, according to CNBC and Reuters. The fed funds rate currently stands at 3.75–4.00%.

Fed officials responded bluntly. Governor Christopher Waller said a 50-basis-point move "should be considered" if core inflation ran at 0.3% or higher — which it did. Chicago Fed President Austan Goolsbee called the report "borderline disturbing."

What about the Bank of Japan?

The yen side of the trade has its own brakes. The BOJ's policy rate sits at 1.25%. Its Summary of Opinions, published November 10, said the next hike should come "without becoming overly cautious." Overnight index swaps price about an 84% chance of a hike at the December 17–18 meeting, per rateprobability.com, while MUFG puts it at 82%.

The rate differential still favors the dollar but isn't stretching much. The US 10-year yielded 4.98% at the November 10 close (Yahoo) against the JGB 10-year at 2.785%, up 10.5 basis points on the day, per Nikkei — a spread of about 2.20 points, because Japanese yields are climbing too.

Then there's Tokyo. Japan has spent roughly 27 trillion yen on currency intervention in 2026, according to ActionForex. Finance Minister Katayama said on November 2 that Japan "will take action" against disorderly moves, as reported by the Japan Times. No fresh warning came this week.

The broader risk tone is positive: the Nikkei 225 rose and Brent traded near $92 on Middle East peace talk, per Yahoo and MUFG. Monday, November 11 is US Veterans Day — the bond market is closed and no US data is scheduled.

Which scenario wins?

AetherEdge assigns probabilities to two paths:

• Scenario A (55%): Fed repricing wins. A 4H close above 159.10 breaks the range top and opens 159.75, then 160.00 — where intervention risk rises fast.
• Scenario B (45%): 159.00 caps again, held down by yen-side brakes — the priced-in BOJ December hike and intervention fear. Price slips back to 158.35, and a 4H close below 158.30 opens the trendline near 157.70.

The invalidation rules are symmetrical. A 4H close below 158.30 cancels the bullish view. A 4H close above 159.10 kills Scenario B and opens 159.75 and 160.00.

What's on the calendar next?

The next 48 hours deliver several potential triggers (all times UTC):

• November 11: US Veterans Day, bond market closed; 23:50 Japan PPI for October
• November 12: 03:35 Japan 5-year JGB auction; 07:00 UK GDP; 13:30 (08:30 ET) US jobless claims, followed by Fed speakers Hammack, Barr, Goolsbee and Daly
• November 13: 13:30 (08:30 ET) US PPI

The setup is now binary: one 4H candle above 159.10 sets up a run at 160.00 and the intervention zone, while a close below 158.30 hands control back to the yen.
