A staggering 83% of the gold bars stored at Fort Knox fail to meet modern international purity standards, rendering much of the US’s reported 8,133.5 metric tons of gold reserves illiquid for global transactions. This revelation casts doubt on the readiness of America’s stockpile—valued statutorily at $42.22 per ounce—for use in international settlements.
The London Bullion Market Association mandates a minimum fineness of 995.0 parts per thousand for ‘good delivery’ bars, with global standards increasingly shifting to 0.9999 purity. Yet, documents from a 2011 House Committee on Financial Services Hearing reveal that 64% of Fort Knox’s gold has a fineness between 0.899 and 0.901, while only 17% reaches or exceeds the 0.995 threshold. The average purity across the US reserves stands at a mere 0.9167, far below what markets demand.
Compounding the issue is the lack of credible audits. The last publicized inspection, a 1974 event widely criticized as a publicity stunt, opened just one of Fort Knox’s 15 vault compartments without verifying serial numbers or testing purity. Subsequent inventory efforts by the US Treasury have been marred by missing reports, broken seals, and untracked bar movements, failing to meet basic transparency standards.

“It’s a decrepit relic just like our monetary policy is. With respect to America’s gold stockpile, we hold ourselves to a lower standard than the rest of the world,” said Stefan Gleason, CEO of Money Metals.
The roots of this predicament trace back to historical policies, notably President Franklin D. Roosevelt’s 1933 Executive Order 6102, which confiscated private gold to bolster national reserves, often without refining to modern standards. Meanwhile, other nations are adapting—France recently sold 129 tonnes of non-standard gold stored in New York, replacing it with higher-quality bars held domestically.
Legislative efforts to address the issue persist, with a bill introduced by Sen. Mike Lee (R-Utah) in 2023 calling for a comprehensive audit and refinement of non-standard bars—a process that could span years. Until then, the US holds 147.3 million ounces at Fort Knox alone, much of it sidelined from global markets.
