The world's 50 most valuable mining companies lost $264 billion of market value in September, ending the month worth $2.26 trillion. Gold's 6.4% fall did most of the damage, and lithium producers all but vanished from the list.
At a glance
- It was the second-largest monthly decline in the ranking's history, erasing three-quarters of August's record $357 billion gain.
- The 15 gold miners in the list lost $79 billion, and none of them rose in September.
- Only one company finished higher: Indonesia's Amman Mineral, up 1.3%.
Background
MINING.COM ranks the world's 50 most valuable listed mining companies by market value at the end of each month. Market value is a company's share price multiplied by its number of shares. Because mining shares move with the metals they produce, the ranking works as a monthly scorecard of how investors feel about gold, copper, iron ore and battery metals.
What happened
The top 50 miners were worth $2.26 trillion at the end of September, $264 billion less than a month earlier. September took back three-quarters of August's record $357 billion advance.
Gold drove both moves. New York gold futures slid 6.4% during the month, from $4,441 an ounce to $4,158, leaving the metal below where it started the year. Silver fell 9%.
Why it happened
The Federal Reserve raised interest rates on September 16 for the first time since 2023. A global bond selloff pushed yields to their highest since 2008, and the dollar firmed. Gold pays no interest, so higher yields made it less attractive, and the miners' shares fell further than the metal.
The 15 gold miners in the ranking lost $79 billion, or 12.7%. Kinross fell 21.3% after cutting its 2026 and 2027 production guidance. Shandong Gold fell 27.8%, the worst move in the list, after lowering its 2026 mined gold target. Gold Fields lost 21% after Northern Star rejected its $27 billion takeover approach.
Copper held up, lithium did not
Copper producers lost $44 billion, a steadier 7.6% fall, as the metal ended the month at $6.56 a pound, three cents below where it began. BHP took the biggest dollar loss in the ranking, $26.4 billion, after a fatal accident and strike vote at its Escondida mine.
Lithium had the worst month. Chinese carbonate futures fell 22.5%, and Albemarle and Ganfeng Lithium dropped out of the list, leaving SQM as the only lithium producer. Gold miners Endeavour Mining and Alamos Gold took their places, and the entry level for the ranking fell to $13.6 billion from $15.6 billion.
Our read
Outlook: neutral. The ranking reflects price moves that have already happened rather than causing new ones. It does show how sharply mining shares amplify swings in gold and lithium.
What to watch
- Whether Gold Fields returns to Northern Star with a larger cash offer, as it is said to be weighing.
- Panama's decision on restarting First Quantum's Cobre Panama copper mine.
- October's ranking, which will show whether gold miners recover with the metal.

Detailed analysis
Timeline
- 2026-09-16: The Federal Reserve raises rates for the first time since 2023.
- 2026-09-28: Northern Star rejects Gold Fields' $27 billion approach.
- 2026-09-30: September ends with the top 50 miners worth \$2.26 trillion.
Interest Rates
The Fed hiked on September 16 and bond yields hit their highest since 2008, weighing on gold.
Currency Impact
A firmer dollar added to pressure on gold and gold miners.
Mining Production
Guidance cuts at Kinross and Shandong Gold deepened their share price falls.
What could lift prices
- Gold miners fell nearly twice as much as gold, so any metal rebound could lift them sharply.
- Takeover interest, such as Gold Fields' approach for Northern Star, shows buyers see value in the sector.
What could weigh on prices
- Further Fed rate hikes would keep pressure on gold and gold-mining shares.
- Production guidance cuts at major producers point to rising operational risk.
Country impact
| Country | Impact | Reason |
|---|---|---|
| China | Medium | Its six companies in the ranking lost \$43 billion, the most of any country. |
| South Africa | Medium | Gold Fields lost \$8.6 billion of market value after its rejected takeover approach. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Gold Mining | Negative | All 15 gold miners in the ranking fell, losing \$79 billion together. |
| Copper Mining | Negative | Copper producers lost \$44 billion even though the metal ended the month nearly flat. |
Who gains, who loses
- Amman Mineral: It was the only company in the top 50 to finish September higher.
- Lithium producers: Albemarle and Ganfeng dropped out of the ranking after lithium fell more than a fifth.
- Gold mining investors: Gold miners lost 12.7%, almost twice the fall in gold itself.
Other ways this could play out
- If the Fed signals it is done raising rates, gold and gold miners could recover part of September's losses.
- If yields keep climbing, gold miners could fall further and the ranking's entry level could drop again.
Price risks
- A further rise in US bond yields would weigh on gold and mining shares.
- More production guidance cuts would deepen losses at individual miners.
Historical comparison
- August 2026: The top 50 gained a record $357 billion, led by $138 billion from gold miners.
