Why Is Gold Falling During a War and an Oil Shock? Follow the Real Yields

Gold is supposed to be the asset people reach for when the world looks dangerous. Right now the world looks dangerous: the conflict involving Iran has kept the Strait of Hormuz at the centre of the news, and Brent crude has traded around $100 a barrel in recent days. Yet gold has gone the other way. On the morning of 29 September 2026, spot gold opened at $4,150.10 an ounce, its lowest level since 5 August and about 10.9% below where it stood a month earlier, according to Yahoo Finance.

So the reader question is a fair one: if there is a war and an oil shock, why is gold falling instead of rising?

The short answer

This month, the war has reached gold mainly through interest rates, not through fear. Higher oil has pushed up inflation worries, the Federal Reserve has started raising rates again, and US real yields — the inflation-adjusted return on safe government bonds, and the clearest measure of what it costs to hold a metal that pays nothing — have climbed sharply. Meanwhile, buying by central banks and Chinese households is still there, but it works on a slower timetable than rate-driven trading.

How an oil shock became a rate shock

The chain of events is visible in official data. On 16 September the Federal Open Market Committee raised the federal funds target range by a quarter point to 3.75%–4.00%, in a unanimous 12–0 vote. The statement said inflation "remains elevated" and framed the move as seeking "a timelier return" to the 2% goal. It was the Fed's first hike since 2023.

Markets did not treat that as the last step. Reports on 23 September put the CME FedWatch probability of another hike in October at nearly 69%, up from about 55%, after strong US business-activity data, and quoted Fed Governor Michael Barr saying that "further policy adjustments are likely to be needed," according to Investing.com. By 29 September, market-implied odds of an October hike were reported at about 70% by USAGOLD, which tied that pricing to crude staying above $100 after Washington rejected an Iranian offer on reopening the Strait of Hormuz.

Bloomberg's reporting, carried by Yahoo Finance on 24 September, summed up the mechanism directly: elevated energy prices were fuelling expectations that the Fed "will need to raise interest rates further to combat inflation," and higher borrowing costs weigh on gold because it earns no interest.

The number that matters most: real yields

The US Treasury's own daily real yield curve shows the scale of the move. The 10-year real yield was 2.42% on 3 September and 2.90% on 28 September — a rise of roughly half a percentage point in under four weeks, with the steepest jump coming between 22 and 24 September. Over the same period the nominal 10-year yield went from 4.79% on 1 September to 5.24% on 28 September, and the 30-year reached 5.56%.

Why does this matter for gold? An investor choosing between a bar in a vault and a US government bond is weighing a guaranteed inflation-protected return of nearly 3% a year against an asset whose return depends entirely on its price. When that guaranteed return rises quickly, some holders — especially funds and traders who bought for momentum — sell gold. Historically the relationship between gold and real yields has not been stable in every period, but this month the two have moved very much in the way the textbook describes.

Oil is taking the "crisis premium"

There is a second, subtler point. In this conflict the most direct economic threat is to energy supply through Hormuz. That makes oil the primary crisis trade. Gold then responds to oil's side effects — inflation expectations and rates — rather than to the headlines themselves. Tellingly, when Brent eased to $97.51 early on 29 September from above $101 a day earlier, per Yahoo Finance, gold steadied rather than slumped further. USAGOLD reported the metal trading at $4,162.84, up 1.14% on the day, in its report the same day.

Why this does not look like a collapse in demand

It would be a mistake to read September's drop as proof that the world has stopped wanting gold. The slower-moving buyers are still active.

• Central banks. The People's Bank of China added 20 tonnes in August, its largest monthly purchase since October 2023 and its 22nd consecutive month of buying, taking reported reserves to 2,387 tonnes, according to the World Gold Council (14 September).
• Chinese investors. Chinese gold ETFs took in 11 tonnes in August, the same WGC update shows. It also notes that Shanghai Gold Exchange withdrawals — a rough gauge of wholesale demand — fell to 62 tonnes, down 22% from July and 27% from a year earlier, so the picture is not uniformly strong.
• Seasonality. China's National Day "Golden Week" runs 1–7 October, a traditional start to peak buying season, as USAGOLD notes. The WGC expects jewellery demand to receive seasonal support as retailers restock for the fourth quarter.

The complication is that August also brought a surge of fast money. Global gold ETFs attracted $18 billion and 121 tonnes that month, with Europe recording its largest monthly inflow on record and North America its third largest, according to the WGC's August ETF report. The WGC attributed part of that to momentum as prices broke technical levels. Money that arrives for momentum can leave for the same reason.

What we know vs. what we're inferring

What we know (from the sources cited):

• The Fed raised rates to 3.75%–4.00% on 16 September, unanimously.
• US 10-year real yields rose from 2.42% (3 September) to 2.90% (28 September), per Treasury data.
• Gold opened at $4,150.10 on 29 September, its lowest since 5 August, and roughly 10.9% lower over one month (Yahoo Finance).
• Market reports put the odds of an October hike at around 69–70% in the last week of September.
• The PBoC bought 20 tonnes in August; global gold ETFs saw record-scale inflows in August.

What we're inferring (our analysis, not established fact):

• That rising real yields, rather than any loss of confidence in gold, are the main driver of September's decline. The timing fits closely, but markets rarely have a single cause.
• That part of the selling is August's momentum-driven ETF money leaving. We have not yet seen official September ETF flow data to confirm this.
• That central-bank and seasonal Chinese demand may soften declines. That is plausible, but these buyers are price-sensitive and their effect is hard to measure in real time.

For context, gold is still about 9.5% higher than a year earlier, per Yahoo Finance, but well below the intraday record of roughly $5,590 set on 28 January 2026, as tracked by MetalCharts. The decline is sharp; it has not erased the longer-term move.

What to watch next

1. 30 September, 8:30 a.m. ET: August personal income and outlays, including PCE inflation, from the Bureau of Economic Analysis. In July, headline PCE inflation was 3.7% year on year and core 3.3%.
2. 1–7 October: China's Golden Week holiday, a test of whether lower prices bring out physical buyers.
3. 2 October, 8:30 a.m. ET: the September US jobs report, per the BLS release calendar.
4. Early October: the WGC's September ETF-flow and central-bank updates, which should show whether August's inflows reversed.
5. 14 October, 8:30 a.m. ET: September consumer price index (BLS).
6. 27–28 October: the next FOMC meeting, per the Fed's calendar.
7. Throughout: any change in the Hormuz negotiations, because oil remains the channel through which the conflict reaches rate expectations — and, through them, gold.

The practical lesson is that gold's "safe haven" label describes a tendency, not a rule. When a crisis shows up mainly as higher inflation and higher rates, the metal can fall even as the headlines get worse.
