Gold Mining Stocks Face a Cost Test as Central Banks Keep Buying
November 3, 2026
Gold demand remains strong, but the latest figures give investors a reason to look closely at what miners spend to produce each ounce.

Central banks bought 321 tonnes of gold in the third quarter, up 42% from a year earlier. Gold funds also returned to inflows after a weaker second quarter. Those figures, published by the World Gold Council on November 3, show substantial demand for the metal.
They offer a less complete answer for anyone considering gold mining stocks. A miner must turn the gold price into earnings and cash. The cost of doing that has been rising quickly, and the latest Federal Reserve decision has given investors another reason to examine how companies fund their operations and new projects.
The distinction matters whenever a strong headline about gold sends investors looking for a mining stock. The metal’s price affects every producer. The benefit that reaches shareholders depends on production, costs, debt and the price already paid for the shares.
What the gold demand report shows
Total gold demand, including over-the-counter activity, reached 1,369 tonnes in the third quarter, down 1% from the same period in 2025. Central bank purchases rose, while gold funds added 211 tonnes. Demand for bars and coins fell 19% as buyers waited for a clearer direction in the price, according to the World Gold Council’s latest report.
The average gold price was US$4,262 an ounce during the quarter, 23% higher than a year earlier. It was also 5% lower than in the second quarter. Both comparisons are useful. Miners may still be selling into a strong market by historical standards, while facing a lower price than they received earlier this year.
The report also records a 3% annual increase in mine production to 1,071 tonnes, a third-quarter high. More ounces sold can help a company’s revenue, provided those ounces can be produced profitably. The industry-wide total cannot tell investors which operators improved their results.
The cost of an ounce is moving too
The World Gold Council’s most recent industry cost figures cover the second quarter, because cost reporting trails production data. Average all-in sustaining costs reached US$1,930 an ounce, up 22% from a year earlier. The council points to higher energy and supply costs, along with a sharp increase in spending needed to sustain operations. These are industry averages, so an individual mine may look quite different.
A simple illustration shows why investors should track both sides of the calculation. Suppose a miner sells gold for US$4,300 an ounce and reports sustaining costs of US$1,900. The gap is US$2,400. If its selling price falls by US$200 and its costs rise by US$200, that gap narrows to US$2,000, even though gold has fallen less than 5%.
That gap is only a starting point. All-in sustaining cost, or AISC, is a widely used measure of what it takes to keep a mine operating. It does not include every demand on a company’s cash, such as building a new mine, paying interest or taxes. Our Mining 101 cost guide explains what to check before treating the difference between the gold price and AISC as profit.
What higher interest rates change
On October 28, the Federal Reserve held its policy rate at 3.75% to 4%. Two voting members preferred a quarter-point increase. The Fed said inflation remained elevated and that it would assess more information before deciding its next move.
Interest rates can influence gold through bond yields and the US dollar, although neither relationship works the same way every time. For miners, there is a more direct question: how much will it cost to borrow, refinance debt or build the next project? A producer with strong cash generation may have room to fund its plans internally. A developer that needs outside capital faces a different test.
Investors should therefore read a gold miner’s financing plans alongside its production guidance. A project can look attractive at today’s gold price and still struggle to reward shareholders if construction costs climb or new shares must be issued to finish it.
The figures worth watching next
The next round of company results will show whether individual miners are controlling costs. Look for ounces sold, the gold price they actually received, AISC per ounce and cash generated after capital spending. Compare those figures with the same periods last year and with the company’s own guidance.
Then read the explanation behind any change. Lower ore grades can leave a mine processing more rock for fewer ounces. Higher fuel costs can lift spending across an entire operation. A new mine may need time to reach its planned output. Those details tell investors far more than a company’s production total on its own.
Central bank buying provides an important part of the gold story. The question for gold mining stocks is how much of a favourable gold market each business can retain after paying to produce, sustain and finance its mines. That answer will emerge company by company as the latest results arrive.
