Silver's Supply Cuts Come With a Catch: The Vaults Are Getting Fuller

Two supply-side shocks are working their way through the silver market at once, yet neither has produced the squeeze that bulls might have hoped for. On one side sits Fresnillo, Mexico's largest primary silver producer, which reported a double-digit decline in output. On the other stands First Majestic Silver's San Dimas mine, where a labour dispute has kept gold and silver production halted for more than a week.

Fresnillo's attributable silver production fell to 10.322 million ounces in the third quarter of 2026, down 11.6% from the same period a year earlier. The company blamed lower ore grades at Juanicipio, Saucito and San Julián Veins, along with the absence of its Silverstream contribution. Crucially for investors, Fresnillo left its full-year production guidance untouched — the weaker quarter did not translate into a downgraded outlook.

At San Dimas, the picture is different in kind. The strike was formally called on 8 October, and the stoppage remained unresolved as of Monday, according to media reports. First Majestic confirmed the operational disruption on 9 October and said it was working toward a resolution. No restart date has been given.

Different Causes, Same Direction

The two setbacks share a common thread — they both hit the supply side — but their origins diverge. At Fresnillo, geology is the culprit; at San Dimas, it is a labour conflict. Neither, on its own, establishes a market-wide shortage, and the latest inventory data reinforce that caution.

The London Bullion Market Association reported on 14 October that London vault holdings stood at 28,985 tonnes at the end of the third quarter, a 3.22% increase from the end of June. Not all of that metal is freely available, however: the London stocks include silver held for exchange-traded funds and other investment vehicles. A build in the vaults is therefore no more a complete measure of available supply than a single mine outage is proof of acute scarcity.

COMEX data pointed the same way. Its 13 October report showed total holdings of 333.2 million fine ounces, of which 103.1 million ounces sat in the "registered" category. The overall figure was 1.2 million ounces above the prior report.

Rate Expectations Still Call the Tune

Precious metals investors who focus only on mine output and warehouse tallies are missing the bigger driver. Rising oil prices, inflation worries and expectations of further US rate hikes weighed on silver yesterday, according to media reports — supply troubles simply were not enough to offset the monetary headwinds.

The metal's recent price action illustrates how fragile sentiment has become. COMEX front-month silver settled yesterday at USD 58.14 per fine ounce, a gain of 1.6%, only to come under pressure today as conflicting signals emerged from US-Iran talks.

Al-Arabiya reported today on a compromise proposal from Qatar and Pakistan that would address demands from both sides and partly accommodate Iran's wish for the release of frozen funds. Silver initially advanced on the news. A diplomat involved in the negotiations then pushed back on the suggestion that a deal was imminent, saying talks were continuing. That leaves the prospect of a near-term breakthrough unconfirmed.

Geopolitical uncertainty cuts both ways for silver. Tensions support safe-haven demand, but higher oil prices feed inflation concerns and, in turn, expectations of further US rate increases — a drag that limits the support from haven buying.

A Data-Heavy Calendar

The next tests arrive quickly. US initial jobless claims are due on 22 October, followed by preliminary purchasing managers' indices on Friday and the S&P Global flash PMIs on 23 October. For silver, the key question is how the bond market digests those numbers.

Soft PMI readings could pull long-term yields lower and lend silver a hand. A robust economic picture, by contrast, could favour higher real yields and weigh on the metal. The data will show whether the recent rebound finds fresh support or founders once again on rate expectations.

Economists surveyed by Reuters do not anticipate quick monetary relief. A large majority expect the fed funds rate to stay put in October, while every respondent polled sees a 25-basis-point hike in December. BNY strategist John Velis likewise expects no move this month, though he views the likely December step as potentially the last of this cycle — an expectation, not a confirmed policy pivot.

The Federal Reserve's decision on 28 October and the PCE inflation report on 29 October will both bear on whether that expected rate path holds. The Fed's own meeting is scheduled for 27–28 October.

For silver, then, the story is a composite of diplomacy, economic data and yields. A Middle East de-escalation could ease energy-driven inflation pressure. Without a let-up in yield pressure, though, a significant headwind for any sustained recovery would remain in place — and the supply cuts alone will not fill that gap.
