How the Hunt Brothers Cornered the Silver Market and Then Lost it All
Until his dying day in 2014, Nelson Bunker Hunt, who had once been the world’s wealthiest man, denied that he and his brother plotted to corner the global silver market.
Sure, back in 1980, Bunker, his younger brother Herbert, and other members of the Hunt clan owned roughly two-thirds of all the privately held silver on earth. But the historic stockpiling of bullion hadn’t been a ploy to manipulate the market, they and their sizable legal team would insist in the following years. Instead, it was a strategy to hedge against the voracious inflation of the 1970s—a monumental bet against the U.S. dollar
Whatever the motive, it was a bet that went historically sour. The debt-fueled boom and bust of the global silver market not only decimated the Hunt fortune, but threatened to take down the U.S. financial system.
The panic of “Silver Thursday” took place over 35 years ago, but it still raises questions about the nature of financial manipulation. While many view the Hunt brothers as members of a long succession of white collar crooks, from Charles Ponzi to Bernie Madoff, others see the endearingly eccentric Texans as the victims of overstepping regulators and vindictive insiders who couldn’t stand the thought of being played by a couple of southern yokels.
In either case, the story of the Hunt brothers just goes to show how difficult it can be to distinguish illegal market manipulation from the old fashioned wheeling and dealing that make our markets work.
