American gold panic
On September 24, 1869, a gold panic broke out in the United States, triggering a financial crisis. The panic, which became known as Black Friday, was the result of a conspiracy between two investors, Jay Gould, later joined by his partner James Fisk, and Abel Corbin, a small time speculator who had married Virginia (Jennie) Grant, the younger sister of President Ulysses S. Grant. They formed the "Gold Ring" to corner the gold market and force up the price of the metal on the New York Gold Exchange. The scandal took place during the Grant Presidency. The Secretary of the Treasury, George S. Boutwell, had a policy to sell Treasury gold at biweekly intervals for a sinking fund to pay off the national debt. Along with other, non-routine gold sales, this infusion of cash acted to stabilize the dollar. The economy had gone through tremendous upheaval during the Civil War 1861-1865 and was not yet fully restored.
Gould hoped to take advantage of Corbin's relationship with his brother-in-law, President Grant, and Gould persuaded Corbin to introduce him to Grant. Gould and Fisk hoped that befriending the President would get them privy information about the government's gold policy—and even prevent the sale of gold—and thereby manipulate the market. It did not work, being foiled by the government, yet resulted in a scandal that undermined both the credibility of Grant's presidency and the national economy. Gould and Fisk used their personal appearances with Grant to gain credibility on Wall Street in addition to using their insider information.
During the first week of September, Grant's Secretary of the Treasury George S. Boutwell received a letter from Grant. It told him that gold sales would be harmful to Western farmers, a notion planted by Gould and Fisk. Boutwell countermanded his own order to sell a great deal of gold, suspending non-routine Treasury gold sales for the rest of the month. At the same time, Gould, now joined by Fisk, continued buying gold through New York City's "Gold Room", raising the price of gold. After learning about the nature of their scheme, Grant first told Corbin to unload his gold holdings before ordering the release of $4 million in government gold on September 24. Grant's move immediately drove down the price of gold, crushing the "Gold Ring"'s corner on the market. A panic on Wall Street ensued and the country went through months of economic turmoil, although a national depression was averted. Gould and Fisk hired the best defense available. Favored by Tweed Ring judges, the conspiratorial partners escaped prosecution. An 1870 government investigation, headed by fellow Republican James A. Garfield, exonerated Grant of any illicit involvement in the conspiracy.
History.
To finance the Civil War and Reconstruction, the federal government had assumed a large national debt, escalating from $64 million in 1860 to $2.8 billion by the end of the Andrew Johnson administration, when Grant was elected president in 1868. The problem was further compounded when the federal government issued paper money during the Civil War, known as "greenbacks", which were not redeemable in gold. Mandated as the only payment for federal debts, "both public and private", these "notes" served to take gold currency out of circulation, in accordance with Gresham's law, causing the price of gold to rise sharply. It was generally believed that the U.S. Government would eventually redeem the "greenbacks" with gold.
Grant believed that putting "sound money" back into circulation was the best approach to restoring the nation's economy. 
Determined to return the national economy to pre-war monetary standards, one of his first actions as president was to sign the Public Credit Act of 1869, which established a 10-year timetable for returning to the gold standard by repaying U.S. bonds in "gold or its equivalent" and redeeming greenbacks from the economy as soon as possible.
Grant had put the talented George S. Boutwell in charge of the U.S. Treasury. Boutwell's primary task was to reduce the national debt. To accomplish this, he ordered his assistant treasurer to begin selling gold from the Treasury and buying up wartime bonds in April 1869. He also initiated reforms in the Treasury Department by improving methods of tax collecting and attacking the problem of counterfeiting. By the end of May, the national debt had been reduced by $12 million. Boutwell's treasury policy of reducing the national debt kept the money supply level and the gold price artificially low. The goal of Grant's policy was to reduce the amount of greenbacks in circulation that could be redeemed in gold at some future date.
Cornering the gold market.
In 1869, Jay Gould, a director of the Erie Railroad, sought to corner the gold market with the connivance of Abel Corbin, a financier with a shady past who was President Grant's brother-in-law. They worked to persuade the President to stop Secretary of the Treasury Boutwell from releasing weekly gold (but not affecting those routine gold sales for the sinking fund) from U.S. Treasury, with the intention of raising the gold price. James Fisk, another director who had made his fortune as a cotton smuggler during the Civil War, controlled the Erie Railroad in conjunction with Gould. He joined the conspiracy in force later on. The first step in Corbin and Gould's plan was to recruit Daniel Butterfield, a former Major General and war hero during the Civil War
 who lacked any experience in finance. Both Corbin and Gould lobbied successfully for Butterfield's appointment as the assistant treasurer, through whom Boutwell gave orders to sell Treasury Department gold. Gould bribed Butterfield with a $10,000 check, more than Butterfield's annual salary of $8,000. Butterfield agreed to tip the men off when the government intended to sell gold.
Corbin was considered a smooth talker and had made money speculating in real estate. More importantly to Fisk and Gould, he had direct access to Grant. They used Corbin's relationship to get close to Grant in social situations, where they argued against government sale of gold, reinforced by Corbin. Gould also attempted to bribe Grant's personal secretary Horace Porter by giving him a $500,000 gold account in his name, but Porter, a former military aide to Grant, stated that he declined the offer. Not accustomed to having such offers turned down, Gould went ahead and made the purchase and opened a brokerage account in Porter's name regardless. When Porter was informed of Gould's unauthorized transaction, he refused the offer in writing. In similar fashion, Corbin approached Grant's wife Julia and attempted to entice her into accepting half interest in $250,000 in bonds, but she turned that offer down.
Gould secured controlling interest in the federally audited New York's Tenth National Bank, a Wall Street broker's bank that was used as a facility to contract business. In addition to meeting at Corbin's mansion, Fisk and Gould also talked with Grant on their Erie Canal railroad car and in Fisk's box seats at New York's Fifth Avenue Theatre. Gould suggested to Grant that increasing gold prices would lower the dollar and allow farmers in the West to sell their crops overseas, but Grant gave no response. Both Grant and Boutwell strongly felt that the nation's wartime debt had to be paid to assure the credibility of the United States in the eyes of the European banks. To accomplish this, Boutwell began selling gold from the Treasury's reserve of $100 million in gold bars, initially without the President's express consent, and using the proceeds to buy back U.S. bonds. Boutwell's controversial approach was later endorsed by Grant, giving Boutwell all the latitude he needed. Boutwell later wrote that only outsiders unaware of the finer designs of his dealings thought "the President was taking any part in the operations of the treasury concerning the price of gold". Grant, meanwhile, was unaware that his appearances in the company of Gould and Fisk sent a message to Wall Street that he supported raising the gold price.
When buying gold and bonds, Boutwell placed all his orders through Daniel Butterfield in New York. To reduce the temptation of illicit dealing, Boutwell, at Butterfield's recommendation, publicly announced his orders by telegraphing the news to the Associated Press. Over the next few months Treasury gold began to flood the market while Boutwell began buying back wartime bonds. By September 1, Boutwell had reduced the national debt by $50 million. He continued this practice at an accelerated rate while Grant, having closely followed Boutwell's dealings, began to express reservations and sent him a letter from Washington, Pennsylvania, criticizing that driving the price of gold down would hurt farmers. Many brokerage firms collapsed while trade volume and agriculture prices plummeted, causing a mild recession, but by January 1870, the economy resumed its post-war recovery. Boutwell saw little merit in either Grant's or Gould's arguments, feeling that the government had no place in manipulating the market regardless of who benefited. However, not wanting to go against the President, Boutwell ordered Butterfield to halt semi-weekly September government gold sales. Believing he now had a "green light" from Grant, Gould began buying gold through brokers at an accelerated rate, increasing his gold stake from $10 to $18 million in specie.
Breaking the "Gold Ring".
Starting on September 1, 1869, Gould and Fisk put their plot into motion by purchasing $1.5million in gold in the names of Corbin and Butterfield. The conspirators would make $15,000 ($ in 2023) for every dollar rise in the price of gold (which was quoted in increments of $100 face value of gold coin, each containing 4.8375 troy ounces). By September 6, the gold quote had risen from $132.50 to $137. By September 7, Gould was faced with a startling reversal when members of his group were directed to sell off the $6million they had achieved during the previous buying frenzy of April 1869. Prices of gold fell sharply from $137 to $134 in one day. Gould lost more than $100,000 in two days.
Abandoned by his associates, Gould looked to Fisk for assistance, but he was away on railroad business. Fisk returned to New York on September 8 and found Gould worried and depressed. Fisk reminded Gould that he still had "enough gold to sink a ship" while the two looked to others and devised other schemes to come out on top, but they knew by this time that if they began buying again, the Treasury would counter their efforts and begin selling at an accelerated rate once again.
Gould and Fisk had a list of every broker and speculator who had borrowed gold from the gold exchange, some 250 in all, including Jay Cooke, the biggest financier on Wall Street and a prominent voice urging Grant to step in and break the "Gold Ring". Fisk proposed that the list be published in the newspapers the next day with the demand that the "bulls and bears" settle on their debts by three o'clock, at a fixed rate of $160. If they refused, Fisk was ready to squeeze them at an even higher rate, a scheme that bordered on blackmail. Fisk's associates scoffed at the scheme and criticized Fisk of being true to form for suggesting such an unconventional idea. After being warned that the idea violated New York State criminal conspiracy law, Gould, Fisk and their associates chose another approach: On Friday, they drove the price of gold to an even higher price by buying large amounts of gold at the current high price and selling even higher, regardless of the political and economic effects. Fisk, however, saw the flaw to this alternative approach, fearing that pushing the price of gold up too quickly would provoke the President to step in and break the gold corner.
On September 12, Grant warned Boutwell that a "desperate struggle" was taking place between the "bulls and bears" of the gold market and that Boutwell should continue the current policy, which was to suspend the sales of gold. Corbin told Gould he was concerned that Grant would start selling gold from the Treasury, so Gould told Corbin to write a letter to Grant encouraging him not to sell. Corbin wrote Grant the letter, now lost, encouraging Grant not to sell gold. Fisk had the letter delivered by William Chapin of the Erie Railroad, to Washington, Pennsylvania, where Grant was vacationing with his wife's cousin. Interrupting Grant's croquet game, Chapin gave him Corbin's letter, whereupon Grant read the
