US CPI, 10 November 2026: Sizing the Dollar Test

US CPI for October is published on Tuesday 10 November 2026 at 8:30 a.m. ET, and it is the last inflation print before the Federal Reserve votes on 8-9 December with futures already pricing roughly a three-in-four chance of another 25 basis point hike — which makes Tuesday a scheduled volatility event to be sized, not a number to be predicted.

I have watched hundreds of traders treat a CPI Tuesday as a forecasting contest. In 37 years in the markets, twenty on institutional FX desks, I never saw a desk make its year by guessing a print — and I have seen plenty of accounts come apart trying. The print decides the volatility. Your process decides the damage.

What lands on Tuesday, and why this one is the last word

The Bureau of Labor Statistics publishes the October consumer price index at 8:30 a.m. Eastern — 13:30 UTC, and 12:30 a.m. Wednesday 11 November in Sydney.

It is the last CPI before the December meeting. The FOMC meets on 8-9 December. The November print is not released until 10 December, the day after the decision, so whatever Tuesday shows is the number the committee carries into the vote.

The Fed has already restarted tightening. It raised the target range 25 basis points to 3.75%-4.00% on 16 September, the first increase since 2023, then held on 27-28 October.

The market has made up its mind. After October payrolls printed +165,000 against forecasts near 59,000-65,000 and unemployment fell to 4.1%, futures moved to price a 76-80% chance of a 25 basis point hike in December. Reuters put it near 80%; Polymarket was at 76.5% on 8 November. A crowd that convinced has to unwind if the number disagrees.

The numbers Tuesday has to move

September was an energy story: gasoline did most of the work and core was firm, not explosive. October nowcasts point to a calmer core reading near +0.2% month on month, because pump prices flattened after the September jump. That is a forecast, not a fact — and a comfortable consensus is what a surprise feeds on.

The dollar is the crowded position

A hot print does not need to change the inflation story to move markets. It only needs to confirm the hike already priced, and that is where the positioning sits.

The dollar index closed at 102.28 on Friday 6 November, up 0.72%, and bid since the payrolls beat. Long dollar is now a consensus trade wearing several tickers: short EUR/USD, short GBP/USD, long USD/JPY and short AUD/USD are one idea, not four.

Confirmation meets profit-taking; disappointment forces the whole book out through the same door. You do not need a view on which happens — only on how much of that single idea you are already carrying.

The local complication. The RBA raised the cash rate to 4.85% on 3 November, the highest in 18 years, with Australian CPI at 4.3%. AUD/USD is pulled by two tightening central banks at once, so an AUD/USD position is not a diversifier against a dollar position — it is leverage on it.

The 13:30 mechanics: the first candle is liquidity, not information

13:30 UTC is the European afternoon and the US morning, so the book is deep — but not in the first thirty seconds. EUR/USD spreads that sit near 0.4 pips can widen to 1.5-4 pips at the release, and the algorithms go hunting for the stops at obvious levels.

The first move is mechanical: stops trigger, thin liquidity amplifies it, and direction frequently reverses once real buyers and sellers arrive. Institutions wait for the second move, because the second move carries the information.

If your plan needs you inside the first thirty seconds, you are paying the spread for the privilege of being early.

How we size it: the worked maths

Here is the version we ran on the desk, applied to a $10,000 account risking 1% — $100 — per trade. On EUR/USD a standard lot pays $10 per pip.

• Normal day: a 35-pip stop. $100 divided by 35 pips is $2.86 per pip, which is 0.28 lots. Risk: $98.
• CPI day: a 95-pip stop, set behind the noise. $100 divided by 95 is $1.05 per pip, which is 0.10 lots. Risk: $95.

Your risk did not move. Your size fell by nearly two thirds. That is the whole discipline: volatility sets the size, not your confidence.

Now price the execution. A 15-pip slip through your stop costs $42 at 0.28 lots and $15 at 0.10 lots. Same market, same mistake, one third of the damage. Do that twice into a daily loss limit and you have spent the day's buffer on execution rather than on being wrong.

The pre-event checklist

• Fix risk in currency, not lots. $100, decided before you look at a chart.
• Widen the stop for event volatility and let the size fall. Never widen the stop and keep the size.
• Count correlated positions as one. Short EUR/USD, short GBP/USD and short AUD/USD is one dollar bet.
• Know the account rules first. Some funded programmes restrict trading around high-impact data, and a breach closes the account regardless of P&L.
• Write the pre-commitment in the journal before 13:29 UTC: size, stop, invalidation, no-trade window, and what you do if price gaps through your entry.
• Keep Friday on the radar. US PPI follows on 13 November at 13:30 UTC, and a second inflation read in the same week needs its own budget, not yesterday's.

None of this predicts the number. That is the point. The framework is built so the outcome never has to be known in advance — fixed risk, size that shrinks when volatility rises, and a daily loss budget that ends the day before it ends the account. Past performance is not indicative of future performance.

The bottom line: Tuesday's CPI is the last inflation print before the Fed decides on 8-9 December, with a hike roughly three-quarters priced and the dollar already long. You do not need a view on the number. Fix the risk in currency, widen the stop so the size falls, count the dollar book as one position, and write the daily budget down before 13:30 UTC — the print sets the volatility, your process sets the damage.
