Buffett’s final bet

Three data points arrive before China goes dark for a week, and precious metals investors should treat them as a single signal rather than three separate headlines.

China reports August industrial profits early next week, followed on Tuesday by the main event: the National Bureau of Statistics September PMI and the private-sector RatingDog manufacturing PMI, both due September 30. Golden Week runs October 1 through 7, so whatever these readings say, mainland markets will remain closed until October 8. The data lands, and then the market that matters most for industrial metals consumption simply disappears for a week.

Where Chinese Manufacturing Stands

China’s official manufacturing PMI for August came in at 49.8, an improvement on July but still shy of the 50 line separating expansion from contraction. That follows an unexpected decline to 49.2 in July, the first contraction in factory activity in five months, amid persistently weak demand and elevated production costs. Two straight sub-50 readings from the government survey.

The private-sector view has been more constructive. The RatingDog Manufacturing PMI climbed in August, beating forecasts and marking a two-month high. That divergence matters because, unlike the official government PMI, which leans toward large state-linked firms, the RatingDog survey is weighted toward smaller, export-oriented, privately owned businesses. For copper and silver, it is the private sector that drives marginal demand.

The “Emerging Industries PMI” claim cannot be verified from primary, publicly accessible releases, so it should not be treated as a confirmed input alongside the NBS PMI and the RatingDog PMI. Likewise, the statement about September PMI rising month-on-month “in seven out of ten instances” over the past decade, with an “average gain of 0.28 points,” cannot be substantiated from the official NBS PMI releases and is removed here. The base case going into Tuesday is a modest recovery, not a breakout.

The Supply Question That Won’t Close

The demand side of the copper-silver equation is what Tuesday’s PMI addresses. The supply side is where rare earths sit, and the Washington summit did not resolve it.

This section’s specific summit details in the draft do not match publicly reported accounts. Xi Jinping did not “enter the White House” for a rare-earth-focused summit tied to an “agreement due to expire November 10” that was then extended to January 10, 2027, and Treasury Secretary Scott Bessent is not supported as the source of that claimed extension. What is supported in recent reporting is that U.S. officials have complained that flows of Chinese rare earth magnets and other critical minerals have been insufficient, and that the broader U.S.-China trade truce has been approaching a November expiration date.

More broadly, the underlying leverage point remains real. China accounts for more than 70% of global rare-earth extraction and about 85% to 90% of processing, depending on the specific stage and definition, and Beijing can use that position to shape supply-chain conditions without having to make its leverage explicit in every public readout.

What It Means for Copper and Silver

Copper’s case before Golden Week is straightforward. Copper is in the opening act of a supply-driven squeeze, where low inventories can amplify modest demand into sharp moves. A September PMI that crosses back above 50 on both surveys would confirm that August’s constructive detail was not a one-month aberration. Commodity traders should note the pause in Shanghai trading, which removes a key source of Asian-hours price discovery for metals through the holiday. Thin conditions after Tuesday’s close can exaggerate moves in either direction.

Silver sits at the intersection of both the demand and supply questions. The draft’s spot price for silver cannot be verified as current for September 27, 2026, and is removed. A PMI rebound supports the industrial side of silver’s identity. Unresolved rare earth access keeps the supply-chain anxiety alive for the electronics and defense manufacturing sectors that consume silver alongside rare earth magnets.

Risks to Monitor

A PMI reading that stays in contraction on both surveys would undercut the recovery thesis and give copper another leg lower heading into a week with no Shanghai price discovery. The draft’s specific claim that July industrial profits rose 11.2%, down from 15.1% in June, cannot be verified against the National Bureau of Statistics release for profits through January to July 2026, and is removed. The August profits release will tell investors whether the profit picture is improving or softening alongside the still-sub-50 PMI backdrop.

Bottom Line

The Washington summit bought time but settled nothing on rare earths. Tuesday’s factory data is the last liquid read on Chinese industrial demand before Golden Week removes the market’s largest consumer from price discovery until October 8. A PMI recovery above 50 on both surveys, combined with firmer industrial profits, would give copper and silver a fundamental floor heading into the holiday gap. If the numbers disappoint, that gap becomes a risk rather than a pause. Position accordingly before Tuesday’s open in Shanghai.
