EURUSD Session Analysis — September 11, 2026: CPI Tests the Post-ECB Reversal

Yesterday's call: the latest recorded 40% containment lead — partial. EURUSD swept both 1.16408 and 1.16076, but never delivered the required 5-pip-displaced H1 close beyond either edge and settled at 1.16089. Last 20 scored: 25% hit / 75% partial / 0% miss.

Session Card

• Day type call: Event-suspended. Preconditions observed: US CPI lands at 12:30 UTC, Lagarde follows at 14:00 UTC, and live H4 ATR is only 22.2 pips despite yesterday's 49.9-pip event range.
• Lean: Neutral / Wait; conditional: short only after a held, displaced H1 close below 1.15916, long only after a held, displaced H1 close above 1.16415. The 40% downside branch does not meet the 55% threshold for an unconditional short lean.
• Lead scenario + weight: CPI-led downside resolution, 40% — an operative 5-point lead over the 35% inline-CPI containment branch.
• Key invalidation: A held, displaced H1 close above 1.16415 flips the conditional short call to the upside branch; a close back above 1.16197 invalidates a triggered downside break.
• No-trade windows: No new entries from 12:00-14:30 UTC around the 12:30 UTC US CPI release and 14:00 UTC Lagarde appearance; reject the first impulse until a completed H1 close or held retest confirms beyond 1.15916 or 1.16415.
• ATR(14, D1): 0.00412 (41.2 pips). Live H4 ATR is approximately 0.002221 (22.2 pips), the mean of the last 10 completed H4 true ranges.
• What's different today: A second tier-1 session follows yesterday's ECB hike: US inflation can reprice the dollar side first, then Lagarde can challenge that move 90 minutes later.

Scenario Map

The decision point is the 12:30 UTC US CPI release, with the 14:00 UTC Lagarde appearance as a second decision window and 1.15916-1.16415 as the confirmation edges; proximity or a wick does not activate a branch.

Prob

40%

Hot CPI reinforces the post-ECB downside break

Trigger

A hot CPI surprise is followed by an H1 close at or below 1.15866, at least 5 pips through 1.15916, or a failed retest of 1.15916 from beneath

Path & target

Acceptance below 1.15916 targets 1.15844; sustained selling then exposes the 20-day floor at 1.15238

Invalidation

H1 close back above 1.16197

Base rate

priors — US tier-1 repricing drives EURUSD's single-day spikes, while displaced range breaks have the strongest continuation base rate

Prob

35%

Inline or moderate CPI traps the first move

Trigger

The first CPI move sweeps 1.15916 or 1.16415 but the next completed H1 candle closes back inside that band, with price still inside after Lagarde

Path & target

Rotate through 1.16089-1.16197 while retaining 1.15916 and 1.16415 as the outer session edges

Invalidation

Held, displaced H1 close below 1.15916 or above 1.16415

Base rate

priors — inline prints favour chop and the first 15-30 minute post-news impulse has elevated sweep-fade risk

Prob

25%

Cool CPI reverses yesterday's rejection higher

Trigger

A cool CPI surprise is followed by an H1 close at or above 1.16465, at least 5 pips through 1.16415, or a held retest of 1.16415 from above

Path & target

Acceptance above 1.16415 targets 1.16537; continued dollar weakness then exposes 1.17111

Invalidation

H1 close back below 1.16197

Base rate

priors — EURUSD range breakouts have the highest setup base rate, but news and London impulses require displacement and a hold

The 40% downside lead reflects yesterday's rejection of 1.16415, the lower-third close, and the failure of a hawkish ECB outcome to sustain the euro. It remains below 50% because CPI is binary, the latest H4 structure has not confirmed below 1.15916, and the 14:00 UTC Lagarde appearance can reverse the first move. The weighting stays close to the last 20-session calibration, where a 41% average lead has hit 42%, while assigning a credible 35% to the inline branch most likely to produce the map's central whipsaw risk.

Driver Stack

• Short-rate differential expectations — agree with Event-suspended and mildly with the downside lead. The ECB raised its policy rate by 25 basis points yesterday, yet EURUSD rejected 1.16415 and closed at 1.16089; today's US CPI can now reprice the Fed side of the differential, while Lagarde can revise the euro side at 14:00 UTC.
• Dollar flows in aggregate — agree with downside risk, but not with an unconditional direction. EURUSD's lower-third close shows dollar-side pressure through price, but there is no fresh direct DXY reading tonight; CPI must confirm whether that flow persists.
• Risk tone — disagree with using risk as a directional trigger. Energy-led inflation concern raises event sensitivity on both sides of the Atlantic, but there is no fresh cross-asset risk reading strong enough to outrank rates or dollar flow.
• Session mechanics — agree with Event-suspended and the conditional lean. W1: the advance from the June lows is balancing below 1.17111, with this week contained between 1.15916 and 1.16537. D1: yesterday expanded to 1.21× ATR, rejected its high and closed in the lower third, but did not settle below 1.15916. H4: the 09:00 UTC selloff was impulsive, the recovery was corrective, and the latest completed H4 sequence reclaimed 1.16089 without recovering 1.16197. Live H4 ATR remains below the 35-pip trend threshold, so London can arm a break but the tier-1 windows decide whether it holds.

Alignment verdict: partial alignment. The rates calendar, failed post-ECB advance and H4 corrective recovery support a downside lead, but the unbroken 1.15916 swing low, compressed H4 volatility and binary CPI outcome prevent full directional alignment. Event-suspended with a conditional lean is the honest call.

Session Map

• Asian / pre-London (21:00-07:00 UTC): The early recovery from 1.16041 to 1.16171 sits between the 1.16089 prior close and 1.16197 pivot. Its extremes are liquidity targets, not defended support or resistance. This window can preserve the inline-containment branch or arm either directional branch, but cannot validate a CPI scenario by itself.
• London ignition (07:00-09:00 UTC): The strongest EURUSD window can test 1.15916 or 1.16415. A London break may show positioning intent, but with CPI still ahead it requires a second break or held retest; a return inside the band activates the containment logic rather than a trend call.
• London follow-through (09:00-12:00 UTC): This window can carry an accepted London move toward a decision edge, but not justify a fresh entry once the 12:00 UTC CPI blackout begins. Overlapping H1 closes around 1.16089-1.16197 keep all three branches unresolved.
• CPI blackout and first reaction (12:00-13:30 UTC): No new entries around the 12:30 UTC US CPI release. A hot result can activate the downside branch through 1.15916; a cool result can activate the upside branch through 1.16415; an inline or moderate result that sweeps an edge and returns inside the band activates the containment branch. The first 15-30 minutes are a sweep-fade window, not confirmation.
• Lagarde blackout (13:30-14:30 UTC): The 14:00 UTC appearance is a second rates decision point only 90 minutes after CPI. Stay flat on new risk: hawkish guidance can challenge a CPI-led euro decline, while dovish guidance can reverse a CPI-led rally.
• Delayed resolution / NY overlap (14:30-16:00 UTC): This is the first clean confirmation window after both catalysts. Held acceptance below 1.15916 activates 1.15844; acceptance above 1.16415 activates 1.16537. Pullbacks formed from 15:00-16:00 UTC are reversal-prone, so do not automatically treat them as continuation entries.
• Late New York (16:00-21:00 UTC): Follow a confirmed branch only while price holds beyond its decision edge. A move that returns through 1.16197 shifts weight back toward containment; an uncatalysed late extension is vulnerable to retracement.
• Dead zone (22:00-23:00 UTC): No fresh entries. Thin liquidity cannot validate acceptance beyond 1.15916 or 1.16415.
• Next-session risk: Lagarde is scheduled again at 10:15 UTC on Saturday, outside the tradable weekday session; do not treat thin weekend liquidity as confirmation of Friday's branch.

No-Trade Conditions

1. Observe the combined event blackout. Open no new position from 12:00-14:30 UTC around US CPI at 12:30 UTC and Lagarde at 14:00 UTC. The overlapping windows make this one continuous stand-aside period.
2. Reject the first post-CPI impulse. Do not trade a wick through 1.15916 or 1.16415. Require at least 5 pips of displacement with a completed H1 close, or a break followed by a held retest after the Lagarde window.
3. Stand aside inside compression. The lead is only 40% and live H4 ATR is 22.2 pips. No trade is justified while completed H1 candles overlap between 1.15916 and 1.16415, especially around the 1.16089-1.16197 internal pivots.
4. Treat a two-edge break as whipsaw, not opportunity. If both 1.15916 and 1.16415 trade before either produces a held H1 close, stop initiating positions until price closes back inside the band or accepts beyond one edge after 14:30 UTC.
5. Abnormal execution cancels the map. Stand aside if spreads exceed twice their normal liquid-session level, price gaps across a decision edge, or post-event H1 candles alternate closes above 1.16415 and below 1.15916.

What to Watch — Invalidation

1. H1 close at or below 1.15866 after CPI, or a failed retest of 1.15916 from beneath: activate the downside branch toward 1.15844; a later H1 close above 1.16197 invalidates it.
2. H1 close at or above 1.16465, or a held retest of 1.16415 from above: invalidate the conditional short call and shift weight toward 1.16537; a later H1 close below 1.16197 invalidates that upside branch.
3. A sweep of 1.15916 or 1.16415 followed by the next completed H1 close back inside the band: reject the directional break and increase the 35% containment branch, provided price remains inside after 14:00 UTC.
4. Acceptance below 1.15844 or above 1.16537: retire the inner 1.15916-1.16415 map and treat 1.15238 or 1.17111, respectively, as the next confirmed range boundary.
