The Hunt Brothers and the 1980 Silver Corner: Silver Thursday Explained

Most market crashes happen to passive investors caught off guard. This one was built by two men who set out to own the world’s silver supply. Nelson Bunker Hunt and his brother William Herbert Hunt inherited enormous oil wealth from their father H.L. Hunt and then spent the 1970s concentrating it into silver with an ambition that no single commodity position had matched in the modern era. The story that followed reshaped not just the silver market but the regulatory structure of every major commodity exchange in the United States.

What follows draws from the public record: the 1981 CFTC Silver Investigation Report, congressional testimony from 1980 Senate hearings, and court records from the Minpeco S.A. v. Hunt antitrust litigation. Nelson Bunker Hunt (1926-2014) and William Herbert Hunt (1929-2021) are both deceased. Other named individuals appear because they are part of the documented judicial record.

Who Were the Hunt Brothers?

H.L. Hunt was one of the richest men in the United States, a Texas oilman who built a fortune in East Texas crude during the 1930s and 1940s. His sons inherited both money and appetite. Nelson Bunker Hunt, born in 1926, was the more prominent of the two: a commodities speculator who had already built a name in horse racing and Libyan oil concessions before silver became his focus. William Herbert Hunt, three years younger, was the quieter partner, more focused on the family’s oil operations, but deeply involved in the silver venture throughout.

Neither brother lacked resources. What drove the silver play was a conviction, documented extensively in congressional testimony, that the U.S. dollar’s decoupling from gold in 1971 made physical commodities the only reliable store of value. Nixon’s closing of the gold window in August 1971 ended the Bretton Woods arrangement under which foreign governments could exchange dollars for gold at a fixed rate. Bunker Hunt viewed what followed as an invitation to inflation and currency debasement. Silver, he told Senate investigators, was his answer.

The 1973 Decision and the Early Accumulation

Silver traded at roughly $1.95 per troy ounce when Bunker Hunt began buying in 1973. He acquired physical silver and futures contracts on the Chicago Board of Trade and COMEX. By 1974 his holdings had grown to a reported 55 million troy ounces, a quantity large enough to draw the attention of the Commodity Exchange Authority, which was the predecessor to the CFTC. He was called before a Senate committee that year and reduced his position under pressure. The episode subsided, but it established the pattern: build large, face scrutiny, pull back temporarily.

Through the middle years of the decade, the Hunts maintained substantial silver holdings without triggering another regulatory confrontation. The strategy was patient. They were acquiring metal at prices that, in retrospect, were extraordinarily low relative to where the market would go.

The International Expansion: IMIC and the Saudi Partners

By 1979 the operation had grown far beyond the brothers’ personal accounts. Court records from the Minpeco litigation document the formation of International Metals Investment Company, known as IMIC, a Bermuda-based entity that brought in Saudi-linked investors alongside the Hunts. The CFTC investigation identified participants including Naji Nahas, a Brazilian commodities dealer with Saudi connections, among those whose accounts were coordinated with the Hunts’ silver position. IMIC allowed the consortium to hold silver across multiple accounts and entities, a structure that later became central to the antitrust argument that the Hunts had organized a market corner rather than pursued ordinary speculation.

The scale of the combined position by late 1979, as documented in the CFTC report and the Minpeco trial record, was estimated at more than 200 million troy ounces when futures contracts were counted at their full underlying metal equivalent. That figure represented a share of above-ground silver supply that no private entity had approached in the modern era.

The Price Spike: Late 1979 Into January 1980

Silver opened 1979 near $6 per troy ounce. The metal had been rising gradually since the mid-1970s, tracking general commodity inflation. What happened in the final months of 1979 was something different: a nearly vertical ascent that defied ordinary supply and demand fundamentals.

By September 1979 the spot price had crossed $10. November brought it past $17. In December silver cleared $25 and kept climbing. Industrial buyers who needed silver for photographic film, electronics, and jewelry faced contracts priced far above any level they had budgeted. Refiners began stripping silverware and scrap to meet demand for deliverable metal.

The peak came the week of January 14-18, 1980. COMEX records show the spot price reaching approximately $49.45 per troy ounce during that period. Silver had risen roughly tenfold from its price two years earlier. Gold had also risen sharply during the same period, but silver’s move was proportionally larger and far more concentrated in a single speculative position.

COMEX and CFTC Move to Break the Corner

The COMEX Board of Governors acted first. On January 7, 1980, the exchange adopted what became known as Silver Rule 7. The rule imposed a position limit of 10 million troy ounces per account. Holders of positions above that level were required to reduce them within 90 days. No new long positions beyond the limit could be opened. The rule changed the market structure overnight: speculators who had built positions on the assumption that they could keep buying were suddenly forced to face exits with no ability to maintain or grow their longs.

A second and more immediate restriction followed on January 21, 1980. The COMEX board declared that silver contracts could be traded for liquidation purposes only. No new long positions of any size were permitted. The market became one-directional for sellers. Anyone holding a long futures position could either deliver against it or sell it. No one could buy new contracts to absorb the selling pressure that was building.

The CFTC conducted parallel investigations and made clear it was prepared to use its own authority to enforce position limits if the exchanges did not act adequately. Congressional hearings before the Senate Subcommittee on Agricultural Research examined the episode as it unfolded, receiving testimony from exchange officials, the CFTC chair, and eventually the Hunt brothers themselves.

Silver Thursday: March 27, 1980

The Hunts and their partners had financed their silver position with enormous borrowings. Bache Halsey Stuart Shields, at the time one of the largest retail brokerages in the United States, held a margin credit exposure to the Hunt entities that was documented in congressional testimony at more than $1.7 billion. Other firms, including EF Hutton, Merrill Lynch, and several banks, held additional exposure through margin loans or as counterparties to silver contracts held as collateral.

Silver had been falling since the January peak as the COMEX rule changes took effect and sentiment reversed. The price dropped through February and into March 1980. Then, on March 25, a margin call arrived that the Hunts could not meet. Over the following two trading days the situation became a cascade: Bache and other creditors could not wait indefinitely for funds that were not coming.

On March 27, 1980, the market gave the day a name it has kept ever since: Silver Thursday. The price came under heavy pressure from the open and did not recover. By the close, silver had fallen from the high-teens range of the previous weeks to approximately $10.80 per troy ounce. The single-session decline was roughly 50%. Industrial buyers who had been paying above $49 for silver just weeks earlier were now watching it trade below $11.

The Federal Intervention and the Bank Rescue

The collapse threatened more than the Hunts’ personal finances. Several major brokerages had accepted silver-related positions as collateral against margin loans. If the collateral had become worthless while the Hunts still owed billions, the losses would have flowed directly to the firms holding that paper. Bache, in particular, faced a situation that could have threatened its solvency.

Federal Reserve Chairman Paul Volcker coordinated with bank regulators to contain the potential for wider financial disruption. A credit facility of approximately $1.1 billion was assembled through a consortium of commercial banks, according to contemporaneous reporting and congressional records. The facility allowed the Hunt entities to restructure their silver-related debt rather than default all at once, giving the market time to absorb the unwinding without a complete meltdown of brokerage credit.

The arrangement did not eliminate the brothers’ ultimate obligations. It was a managed unwind designed to protect the credit system. The Hunts remained personally liable for debts they no longer had the assets to cover, and that liability would follow them for years.

Aftermath: Bankruptcy and the Collapse of the Fortune

The years after Silver Thursday were a long unraveling. The Hunt family’s main holding company, Placid Oil, filed for bankruptcy reorganization in 1986 as low oil prices compounded the silver losses. Nelson Bunker Hunt filed for personal bankruptcy protection in 1988, by which point his personal liabilities substantially exceeded his assets. One of the largest private fortunes in American history had been consumed by a single commodity speculation.

The remaining physical silver that the Hunts and their partners had accumulated had to be sold, which kept downward pressure on silver prices through the early 1980s. Silver traded in the $8 to $16 range for most of the decade. For investors researching how to buy silver today, understanding the scale of that overhang helps explain why silver prices remained depressed for years after what had briefly looked like a structural shift to a new price level.

The 1988 Minpeco Verdict

The legal reckoning came in a federal courtroom in New York. Minpeco S.A., a Peruvian state mining company, had sold silver forward in the late 1970s as part of its normal operations. When the Hunt position drove prices to $49, Minpeco faced catastrophic losses on those short hedges. After the collapse, Minpeco brought an antitrust lawsuit in the Southern District of New York, arguing that the Hunts and their partners had conspired to monopolize the silver market in violation of the Sherman Antitrust Act.

The trial record, which included testimony from the Hunt brothers and extensive documentation of the IMIC structure and account movements, gave the jury a comprehensive picture of how the position had been built. In August 1988, the jury found for Minpeco and awarded damages that, after the trebling available under antitrust law, reached approximately $134 million. The verdict confirmed what the CFTC investigation had concluded seven years earlier: the accumulation had been a coordinated attempt to control the silver market, not ordinary speculative investment.

What Changed After the Hunt Corner

The CFTC and the commodity exchanges drew specific lessons. Position limits for physical commodities were codified and strengthened. The principle that any single entity or coordinated group should be prohibited from holding a position large enough to dictate prices became an explicit regulatory mandate. These limits now apply across energy, agricultural, and metals markets and are periodically reviewed by the CFTC.

The episode also influenced how exchanges handle existing large positions when emergency rules are adopted mid-crisis. The question of whether retroactive position limits breach existing contracts has been debated in the legal and regulatory literature ever since. The exchanges generally prevailed on this point in subsequent litigation, establishing that their rule-making authority to protect market integrity supersedes individual contract expectations in extreme circumstances.

Silver Thursday is now a standard reference case in commodity regulation courses, financial law programs, and investment risk management training. The phrase “cornering a market” acquired a precise legal and practical meaning shaped almost entirely by this episode.

The Hunt Corner vs. the 2021 Silver Squeeze

When retail traders on WallStreetBets turned their attention to silver in late January 2021, commentators immediately invoked the Hunt brothers. The comparison is instructive but imprecise. The 2021 silver squeeze produced a price spike to approximately $29.40 per troy ounce on February 1, 2021, followed by a rapid retreat. A broader look at the last three decades belongs in our silver price history guide.

The structural difference is leverage and coordination. The Hunts could threaten a genuine corner because they were willing and able to demand delivery of physical silver against futures contracts held at scale. Retail buyers in 2021 bought ETF shares and physical coins, not deliverable futures positions sized to squeeze short-sellers. No regulatory body had to intervene because no entity was positioned to hold the market hostage. The 2021 episode was a demand wave. The 1980 episode was a designed corner. Both moved prices. Only one of them triggered emergency rule changes and ended in federal court.
