Gold fell 6% in September. Why were ETF buyers still adding?

Gold just had a bruising month. Spot gold fell 6.3% in September, according to State Street Global Advisors' October Monthly Gold Monitor, and it was still trading around $4,168 an ounce at 9:05 a.m. ET on October 6, per Fortune — roughly $239 below where it stood a month earlier. When a market drops that quickly, the usual assumption is that fund investors are bailing out. So the question readers keep asking is simple: when gold slides this hard, are ETF investors heading for the exit — and what does the flow data actually say?

The short answer

In the United States, at least, they were not. State Street reports that US-listed gold ETFs took in $3.7 billion of net new purchases in September “during the sell-off,” bringing third-quarter inflows to $11.7 billion. The global September tally from the World Gold Council has not been published yet, so the full picture is still incomplete. What the available data does suggest is that the selling pressure came mostly from somewhere other than buy-and-hold fund investors — and that even the bulls are now hedging their language.

What the September numbers show

The key line in State Street's report, written by a team that includes Aakash Doshi, is blunt: “US-listed gold ETFs posted $11.7B in inflows in Q3, including $3.7B of net new purchases in September during the sell-off.” The same report notes that the sector had seen $5.6 billion of outflows in Q2, so the third quarter marked a clear reversal in US fund demand.

That September figure followed an exceptional August. According to the World Gold Council's August 2026 ETF report (published September 9), global physically backed gold ETFs attracted US$18 billion in August, the second-largest monthly inflow on record. Holdings rose 121 tonnes to a record 4,189 tonnes, and assets under management reached US$615 billion. By region, North American funds added US$7.7 billion, European funds US$7.9 billion (their strongest month on record) and Asian funds US$2 billion.

A flow is not a price

It can seem contradictory for money to flow into gold funds while the price falls. It isn't. ETF creations are only one channel of demand in a much larger market. The same WGC report put average global gold trading volumes at roughly $430 billion a day in August, against gold ETF trading of about $8.7 billion a day. A few billion dollars of monthly net buying can coexist with a falling price if other participants — futures traders, over-the-counter dealers, short-term funds — are selling more.

So who was doing the selling?

State Street's explanation centres on rates and the currency: “The subsequent back-up in yields across the US curve boosted the dollar to two-month highs and weighed on gold via denomination effects and higher opportunity costs.” The report also notes that the Federal Reserve raised rates by 25 basis points in September.

Positioning is the other likely piece. The WGC said that August's rally “likely attracted additional tactical and institutional demand” as gold broke key technical levels. By the end of August, total COMEX net longs had climbed 39% to 753 tonnes, with managed money — typically hedge funds and commodity trading advisers — at 470 tonnes, above its year-to-date peaks. A crowded, momentum-driven long position in futures is the natural candidate for fast liquidation once the trend turns. A report by Invezz (October 1) made a similar case, saying algorithmic and momentum funds reversed positions as technical signals deteriorated. We have not independently verified the latest CFTC data, so treat this as a well-supported hypothesis rather than an established fact.

The bank view: trimmed, not abandoned

Forecasters have been revising, but mostly at the margins:

• Goldman Sachs cut its end-2026 forecast to $4,650 from $4,900 while keeping its $5,400 target for 2027, according to investingLive (September 23). The bank argued that “much of the tightening is already reflected in softer ETF demand” — a view that sits uneasily alongside State Street's US data and may refer to global or longer-run trends.
• Morgan Stanley strategist Amy Gower described $4,000 an ounce as a strong floor on a 12-month view, saying the recent decline “is not enough to undermine the longer-term case for holding it,” per investingLive (September 30).
• State Street itself lowered the probability of its base case — gold rising to $4,750–5,500 by the end of the first quarter of 2027 — to 60% from 70%. Its bear case, at 35%, has gold holding the $4,000–4,750 range of the third quarter over the next six to nine months.

State Street also listed technical reference points as of September 30: a 50-day moving average near $4,322, a 200-day average near $4,539 and a key support floor around $4,000. With the price in the high $4,100s, gold is trading below both averages.

What we know vs. what we're inferring

What we know (sourced):

• Spot gold fell 6.3% in September (State Street).
• US-listed gold ETFs had $3.7 billion of net inflows in September and $11.7 billion in Q3, after $5.6 billion of outflows in Q2 (State Street).
• Global gold ETFs took in US$18 billion in August; holdings hit a record 4,189 tonnes (WGC).
• COMEX net longs were 753 tonnes at end-August, managed money 470 tonnes (WGC).
• Gold was near $4,169.68 at 9:00 a.m. ET on October 6, per CNBC Select, consistent with Fortune's $4,168 at 9:05 a.m. ET.

What we're inferring:

• That futures and short-term momentum positioning, rather than ETF holders, did most of September's selling. This is plausible given August's positioning data but not confirmed by data we verified.
• That global ETF flows in September were also resilient. We only have the US figure; European and Asian flows could tell a different story.
• That continued inflows signal conviction. Some of these purchases may be tactical dip-buying that could reverse.

What to watch next

• Wednesday, October 7, 2:00 p.m. ET (3:00 p.m. UTC-3): minutes of the Fed's September 15–16 meeting, per ActionForex and the Federal Reserve calendar. Watch whether the dollar and yields move — the channels State Street blamed for September's decline.
• Friday, October 9, typically 3:30 p.m. ET (4:30 p.m. UTC-3): the CFTC's Commitments of Traders report, the most direct check on whether managed-money longs have been cut.
• Early October (date not yet confirmed): the World Gold Council's September ETF report, which will show whether European and Asian funds matched US buying.
• October 27–28: the next FOMC meeting, per the Federal Reserve calendar.
• Price reference points: the roughly $4,000 floor cited by both State Street and Morgan Stanley, and State Street's 200-day average near $4,539.

The bottom line: September's slide looks less like a fund-investor stampede than a repricing driven by yields, the dollar and fast-money positioning. The next two weeks of data will show whether that distinction holds.
