Beginning in the early 1970s, Hunt and his brother William Herbert Hunt began accumulating large amounts of silver. By 1979, they had nearly cornered the global market.[6] In the last nine months of 1979, the brothers profited by an estimated $2 billion to $4 billion in silver speculation, with estimated silver holdings of 100 million ounces (6.25 million pounds).[7]
During the Hunt brothers' accumulation of the precious metal, prices of silver futures contracts and silver bullion during 1979 and 1980 rose from $11 an ounce in September 1979 to $50 an ounce in January 1980. Silver prices ultimately collapsed to below $11 an ounce two months later. The largest single day drop in the price of silver occurred on Silver Thursday.[1]
Hunt filed for bankruptcy under Chapter 11 of the Federal Bankruptcy Code in September 1988, largely due to lawsuits incurred as a result of his silver speculation.[1]
In 1989 in a settlement with the United States Commodity Futures Trading Commission, Nelson Bunker Hunt was fined US$10 million and banned from trading in the commodity markets as a result of civil charges of conspiring to manipulate the silver market stemming from his attempt to corner the market in silver.[1] This fine was in addition to a multimillion-dollar settlement to pay back taxes, fines and interest to the Internal Revenue Service for the same period.[1]
