ISM Manufacturing PMI and Gold: How the Prices Index Moves XAUUSD

Short answer: the ISM manufacturing PMI is a monthly survey of US purchasing managers, released at 10:00 am New York time on the first business day of each month (15:00 GMT and 20:30 IST in winter). Gold reacts mainly through what the report does to Fed expectations, Treasury yields and the dollar. A hot report, and especially a high prices index, tends to push those up and weigh on gold in the short term; a weak report does the opposite.

In our COMEX gold data since 2010, the first trading day of the month has been a little busier than an average day: an average absolute move of 0.93% against 0.76%. That is a modest effect, well below payrolls or CPI days, and it comes with an important caveat explained below. Today, 2 November 2026, the October report is due at 15:00 GMT, and the daily digest covers what is expected.

What the ISM manufacturing report actually measures

The Institute for Supply Management (ISM) asks purchasing and supply executives at US manufacturing companies whether conditions in their business are better, the same or worse than the previous month. The answers are turned into diffusion indexes: roughly, the percentage reporting an increase plus half the percentage reporting no change. A reading above 50 means more firms say things are expanding than contracting.

The headline PMI is built from five equally weighted sub-indexes:

Several other indexes are published in the same release but are not part of the headline number, including prices, backlog of orders, new export orders and imports. ISM also publishes an estimate of the PMI level that, over time, is consistent with growth in the overall economy. That level is re-estimated when seasonal factors are revised and has recently been in the low 40s (42.5 in early 2024 reports), which is why a reading of 47 or 48 does not by itself mean recession.

For a one-line definition of the term, see the PMI glossary entry.

Why gold cares about a factory survey

Manufacturing is a smaller share of the US economy than services, so why does gold move on it? Three reasons.

1. Timing. ISM is the first major US data point each month. It arrives before payrolls, CPI and retail sales, so it sets the tone for how the market reads the rest of the month.
2. The Fed link. Gold pays no interest. When strong data raises the odds of higher rates, the yield on cash and bonds rises, and so does the opportunity cost of holding gold. Our real yields and dollar tool shows how closely gold has tracked that cost.
3. Inflation signals. The prices index is one of the earliest readings on input costs. When oil and metals rise, it often moves before consumer inflation does.

That last point is why the report matters more than usual in 2026. With Brent crude above $100 for much of the autumn and the Fed openly debating a December hike, a high prices index adds to the case for tighter policy. Our article on December Fed hike odds explains how those probabilities are read.

The prices index in 2026

The September 2026 report, released on 1 October, showed:

Source: ISM data as reported by Phantom Trading. Forecasts are the published market consensus.

The headline was slightly below forecast, which on its own might have been mildly gold-positive. But the prices index beat the forecast by more than five points and rose 6.8 points in a month. The rise was tied to energy, with petroleum-related industries leading. In a year when inflation is the market’s main worry, that kind of surprise matters more than a few tenths on the headline.

So, for the October report today and the months after it, gold traders tend to watch the numbers in this order:

1. Prices index: another very high reading keeps hike pressure on; a fall towards the low 70s would ease it.
2. Headline vs forecast: the size of the surprise matters more than the level.
3. Employment index: a preview for Friday’s jobs report.
4. New orders: whether the expansion is likely to continue.

Release time in your time zone

ISM is released at 10:00 am New York time. Because the US clocks went back on 1 November 2026, the conversion changes from today:

These are times for a normal year; Europe and Australia also change clocks on their own dates, so for any specific week check our gold economic calendar, which converts every release to your own zone. ISM services follows two business days after the manufacturing report, at the same time of day.

Note that 10:00 New York is 90 minutes after the 8:30 am US data slot and in the middle of the London–New York overlap, which our when does gold move most tool shows is already the most active part of gold’s day.

What gold has done on ISM release days

We looked at every first trading day of the month from February 2010 to October 2026 in COMEX gold futures daily data, 185 days in total. January is left out because the New Year holiday often pushes ISM to the second or third business day. The table compares those days with every trading day in the same period.

Source: XAUUSD Global calculation from COMEX gold futures daily data (assets/data/gold-daily.json). The first trading day is used as a stand-in for ISM day; ISM sometimes publishes on a different day.

Three honest caveats:

• The first of the month is not only ISM. Month-start portfolio flows, other countries’ PMIs and sometimes central bank decisions land on the same day. Some of the extra movement belongs to them.
• The median barely moves. The mean is pulled up by a few big days. On a typical ISM day, gold behaves much like any other day.
• Daily data cannot isolate the 10:00 minute. A close-to-close move includes everything that happened in 24 hours.

Recent years have been louder. In 2025 the average absolute move on those days was 1.69%, and in 2026 so far 1.41%, with an average range of 3.40%, but gold has been far more volatile on every day in that period. In 2026 the first-day moves were split: five up and four down, from a 3.56% rise on 1 April to a 1.95% fall on 2 February.

For comparison, our studies of gold on CPI days and gold on NFP days show bigger and more consistent reactions. ISM is a second-tier event for gold most months, and it can still be the biggest event on a quiet day.

A worked example: reading a hot prices index

This is a hypothetical example to show the chain of reasoning, not a forecast.

Suppose the forecast for the prices index is 75 and the release shows 80, while the headline PMI is in line.

1. Traders read the surprise as more inflation pressure in the pipeline.
2. Fed funds futures move slightly towards a hike; the 2-year yield rises a few basis points.
3. The dollar index firms.
4. Gold, which was already under pressure from hike bets, dips as the cost of holding it rises.

Now flip it: prices at 70 against a forecast of 75. The same chain runs in reverse, and gold may get a lift. The size of either move depends on what else is happening. In a week with the jobs report three days later, many traders hold back, and the first reaction can fade by the end of the day.

How ISM fits with the rest of the month’s data

ISM is the opening act. A practical routine for the first week of a month:

1. Monday (usually): ISM manufacturing at 10:00 New York. Note the prices and employment indexes.
2. Tuesday: JOLTS job openings in many months.
3. Wednesday: ADP employment and ISM services. The services prices index matters as much as the manufacturing one.
4. Friday: the employment report at 8:30 am New York. See the NFP day playbook.

When manufacturing and services both show hot prices, the market tends to take the inflation message more seriously. If they disagree, the payrolls report usually decides the week. Our economic calendar guide lists the dates of every major release, and the GDP report article explains how the quarterly growth number fits in.

Common mistakes on ISM day

• Trading the headline only. In 2026 the prices index has often mattered more than the headline.
• Forgetting the clock change. Twice a year the release moves by an hour for traders outside the US. In early November and in March, check the time again.
• Treating 50 as a recession line. A PMI below 50 means manufacturing is contracting, not that the whole economy is.
• Ignoring the forecast. Markets react to the surprise, not the level. A PMI of 52 can be bad news for gold if 50 was expected.
• Over-sizing because “it is only ISM”. The average move is small, but the biggest days are not.

Key takeaways

• The ISM manufacturing PMI comes out at 10:00 am New York time on the first business day of each month: 15:00 GMT and 20:30 IST in US winter time.
• Gold reacts through Fed expectations, yields and the dollar. Hot data and a high prices index tend to weigh on gold in the short term.
• In 2026 the prices index has been the part to watch; it rose to 77.9 in September.
• On first-of-month days since 2010, gold’s average absolute move was 0.93% against 0.76% on all days. Expect a modest effect most months.
• Use the report as context for the week, not as a stand-alone trade trigger.
