How Much Gold is in Fort Knox?

The United States Bullion Depository at Fort Knox holds 147.3 million troy ounces of gold — roughly 4,583 metric tons — making it the largest single gold storage facility in the United States and one of the most secure buildings in the world.

Located adjacent to the Fort Knox Army installation in Hardin County, Kentucky, the depository is operated by the U.S. Mint on behalf of the U.S. Department of the Treasury, which officially owns the reserves. Because access is restricted exclusively to authorized personnel, the vault's contents have fueled decades of public curiosity and conspiracy theories — but official audits and congressional inspections confirm the gold remains. Highlighting this ongoing fascination, President Trump mentioned in a recent interview that he plans to promote a thorough audit of the contents in the United States Bullion Depository at Fort Knox.

The land now occupied by the depository once belonged entirely to the United States Armed Forces before its transfer to the Treasury. While the surrounding military post was a pivotal location during the Civil War, World War I, and World War II, it is the billions of dollars in gold reserves safely locked inside the vault that continue to capture the world's attention. Exploring this legendary facility reveals a rich history and a profound importance to the American economy.

Key Takeaways

• Total Gold Reserves: Fort Knox securely houses 147.3 million troy ounces (4,583 metric tons) of deep storage gold bullion, accounting for over half of the United States' sovereign gold reserves.

• Strict Security Architecture: The facility utilizes a 20-ton blast-proof main vault door with a 100-hour time lock, enclosed by a perimeter guarded heavily by the U.S. Mint Police.

• Historical Asset Protection: Beyond gold, the depository's ultra-secure vaults have historically protected invaluable artifacts, including the U.S. Constitution, the Declaration of Independence, and the British Magna Carta.

• Official Verification: Public entries are restricted, but official physical inspections—such as the congressional visit in 1974 and the Treasury inspection in 2017—historically confirm that the physical gold remains intact.

Historical Background

First Installations during the Civil War

The first fortifications near the site were constructed in 1861 and named Fort Duffield. It was located on a strategic point, a place named Muldraugh Hill, which overlooked the Salt and Ohio rivers and the Louisville and Nashville Turnpike. During the Civil War, the area was constantly raided and contested by both the Union and the Confederate Forces.

Establishment of Fort Knox as an Army Post during World War I

After the Civil War, the area was fully occupied by the United States Army. In 1918, the construction of a new training camp began and it was named Fort Knox, named after Henry Knox, who was the Continental Army's first chief of artillery during the Revolutionary War and the first United States Secretary of War.

Construction of the United States Bullion Depository

United States Bullion Depository 

The U.S. Department of the Treasury built the Bullion Depository in 1936 on land transferred from the Army Post in Fort Knox, Kentucky. The building is only two stories high, sitting on 4,000 square feet in the intersection between the now named Bullion Boulevard and Gold Vault Road.

The vault was built using reinforced steel plates, steel I-beams, and steel cylinders with hoop bands, and encased in concrete. The following table details the materials used to construct this secure facility:

(Note: The conversion to modern prices reflects an average inflation rate of 3.57% per year since 1936).

The words "United States Depository" are inscribed on the marble front entrance below the seal of the Treasury Department. Only a few people know the facility's complete structure and content.

Role of Fort Knox during World War II

Fort Knox's military facilities were instrumental in training and housing American troops during the Second World War. The base was home to the Armed Force School and the Replacement Center, which provided training in operating tanks and other armored vehicles.

The Bullion Depository didn't always hold only gold. It also served to protect some important historic documents during the war, as it was already considered one of the most secure buildings in the country. Both the original Declaration of Independence and the U.S. Constitution were transferred to the vaults in Fort Knox for protection.

The British Magna Carta was also safeguarded in the vaults during the war. It had come to the United States in 1939 to be exhibited during the World's Fair. With the beginning of the war, the document was stored in the Fort Knox Depository for protection and only returned to England in 1947.

The Depository also safeguarded the Crown of St. Stephen and the Hungarian Crown Jewels, including a gold scepter, orb, and encrusted mantel, which the Royal Hungarian Crown gave to the U.S. military authorities after the war.

During the Cold War, the Federal Government also stockpiled medicines, such as morphine and opium in the Fort Knox depository, as they feared a direct confrontation with the Soviet Union could cut them off from supplies.

Why Build the Fort Knox Bullion Depository?

The price of gold had grown substantially during the Great Depression, prompting the ending of the gold standard in the United States and Gold Confiscation Act (Executive Order 6102), signed by President Franklin D. Roosevelt in 1933, which required every US citizen to surrender all but small amounts of gold coins and gold jewelry to the Federal Reserve in exchange for $20.67 per troy ounce.

As a result, the Federal Government stockpiled a massive amount of gold reserves, creating the need for the construction of a secure vault. Fort Knox, Kentucky, was chosen because of its centralized location and the nation's military presence, which would increase security.

First Gold Shipments to Fort Knox

The first gold shipments to the United States Depository came in 1937 by registered mail from the Philadelphia Mint and the New York Assay Office. The transportation, which involved taking the gold bullion from postal trucks to trains and finally to Army trucks on the final leg of the trip, was overseen not only by the US Post Office but also by a task force that involved local law enforcement, the US Mint Police, and the US Army.

First Gold Shipment to Fort Knox by U.S. Mail

The second shipment happened in 1941. The two shipments together accounted for over 417 million ounces of gold. Each gold bar held in Fort Knox weighs about 400 troy ounces of pure gold, and measures 7 inches long, 3.5 inches wide, and 1.75 inches high.

How Much Gold is Actually in Fort Knox?

Because rarely anyone other than staff members has entered the vaults at Fort Knox, part of the American public finds it hard to believe the place really holds as much gold as stated in official records, despite its legendary renown as one of the most secure buildings in the world and its role in strengthening the U.S. economy.

According to official statements, the gold Fort Knox holds amounts to 147.3 million troy ounces of gold, or 4,583 metric tons (1 metric ton is equal to 32,150.7 troy ounces) at a book value of $42.22 per ounce. There has been no registered gold removed from Fort Knox since 1974, further fueling conspiracy theories surrounding the place.

For investors inspired by Fort Knox's gold holdings, SD Bullion offers a wide selection of gold bars in similar .9999 fine formats — the same purity standard used in U.S. government reserves.

U.S. Treasury Fiscal Data

Has Fort Knox Gold Ever Been Audited?

Public skepticism regarding whether the gold is truly inside the vault has persisted for decades. To address growing rumors that the vault did not actually hold any gold, a congressional delegation and a group of journalists were allowed inside Fort Knox's gold vault for inspection in 1974.

43 years later, in 2017, Treasury Secretary Steve Mnuchin, Kentucky Governor Matt Bevin, and congressional representatives were also permitted to enter the vault.

Today, an ongoing partial audit process is conducted by the Treasury's Office of Inspector General. However, the fact that no full, entirely independent physical audit has been completed continues to frame both sides of the debate factually, keeping the high-volume query of a total modern audit at the forefront of public and political interest.

How Much Is the Gold in Fort Knox Worth Today?

Because the value fluctuates constantly with the global spot price, any fixed number quickly updates with market changes. To find the real-time value, the U.S. Treasury's deep storage weight can be calculated using this formula:

Total Value = 147.3 million troy ounces x current spot price

As of June 2026, using this exact formula with the current spot price ($147,300,000 x $4,350), the total value of the depository’s stash scales to an astounding $640,755,000,000!

Government Involvement and Oversight

The U.S. Department of the Treasury owns and manages the gold reserves at Fort Knox. The U.S. Mint, which is an agency of the Treasury, is responsible for the operation of the Bullion Depository at Fort Knox and the security of the gold stored there.

President Roosevelt was the first non-staff member to visit the vaults in 1943. In fact, he remains the only US President to inspect the gold reserves in Fort Knox.

Visiting Fort Knox

No visitors are allowed inside Fort Knox. Have you ever heard the phrase "As safe as Fort Knox"? It has become general knowledge that the bullion depository is one of the safest places on the planet. No wonder the US Government has chosen it to house gold and other precious metals.

The precise number and nature of security measures in the place is not known by the general public. The outer wall of the building is made of 4-foot-thick granite-lined concrete, with elevated guard boxes on all four corners. The building has some of the most advanced surveillance systems in the world, including video monitors, motion detectors, and redundant alarm systems in case of a breach.

The building is guarded by the US Mint Police. The bullion depository itself lies below the building. The 22-ton vault door is set on a 100-hour time lock. It can only be opened by two staff members with separate codes. Inside the vault, the gold bars are placed in smaller rooms, each protected by 27-inch-thick vault doors.

Though the bullion depository is off-limits to non-authorized personnel, the Fort Knox Military Facility is open to authorized visitors following strict security protocols. One notable example is the General George Patton Museum of Leadership.
