‘s recent new covid-19 epidemic has led to an increase in demand for cash. Many Thai people choose to take advantage of the rising price of gold to sell gold in exchange for more cash. The picture shows people selling gold goods in a gold shop in Bangkok. Since the beginning of this year, the international gold price has risen strongly, and the cumulative increase of New York gold futures price this year has reached nearly 35%, once breaking the $2000 per ounce mark. Although there was a correction on August 11, it also remained above $1900 per ounce. According to the analysis, affected by the epidemic situation, the downward pressure on the economy of many countries has increased, and the global geopolitical uncertainties have increased. In the face of the turbulent situation, gold is favored by investors because of its risk aversion property. < / P > < p > gold can not only avoid risks, but also become the “life-saving money” of some countries. It is reported that Venezuela, suffering from US sanctions, recently tried to withdraw gold stored there from the Bank of England for the purchase of anti epidemic materials and food, but it was rejected by the British side, causing heated international public opinion. The latest news is that the London High Court recently made a ruling in favor of Venezuela, ruling that the Maduro government has the right to appeal against the ownership of gold. < / P > < p > gold is so important, so where is the world’s largest store of gold? According to the relevant data released by various countries, about half of the world’s official gold reserves are in fact among the top three Treasuries in the world – the Treasury of the Federal Reserve Bank of New York, the Treasury of the Bank of England and the national treasury of Fort Knox. < / P > < p > since Swiss banks usually do not disclose the number of BRICs they have stored, the world’s largest vault is the underground vault of the Federal Reserve Bank of New York according to public data. < / P > < p > the New York Federal Reserve is located at 33 Liberty Street, lower Manhattan, New York, less than 5 minutes’ walk from the New York Stock Exchange on Wall Street. The Treasury of the New Zealand Federal Reserve is 24 meters underground. You can take the internal elevator to the fifth floor underground to reach the Treasury. According to reports, the only channel between the vault and the outside world is a cylindrical iron gate with a height of 2.7 meters and a weight of 90 tons. The iron door is fixed on the 140 ton reinforced concrete frame, which can be rotated manually in the vertical direction. After 90 degrees, a narrow passage is exposed in the center, from which the staff can get in and out. < / P > < p > the vault is surrounded by hard bedrock that supports countless skyscrapers on Manhattan Island. Among the “abnormal passageways” supposed by the US media to reach the Treasury, the nearest route is to start from Fulton subway station nearest to the New York Federal Reserve and dig a 300 meter long passageway downward in the direction of the New York Federal Reserve. But it is said that it will take two months to dig such a tunnel even with the best equipment. < / P > < p > the New York Federal Reserve underground vault covers an area of about 300 square meters, which is divided into 122 compartments with metal fences, and each compartment is neatly stacked with gold bricks. The entrance to the vault and the doors of the internal compartments are protected by multiple code locks. The New York Fed claims that no one in the world has the full set of keys and passwords to enter any compartment. When the bricks are put into and out of the warehouse, there must be three staff members present to operate. In addition, the Treasury has 24-hour monitoring and mobile sensing alarm, as well as armed guards. Thanks to solid design and construction, strict monitoring and standardized operation, the New York Federal Reserve underground vault has never been stolen since it was opened in 1924. < / P > < p > according to the information released by the New York Federal Reserve in 2019, there are about 497000 pieces of gold bricks in the underground vault, weighing about 6190 tons, accounting for about a quarter of the world’s official gold reserves. At $2000 an ounce, the total value of the gold is more than $386 billion. At its peak in the 1970s, the Federal Reserve had 12000 tons of gold in its underground vault. < / P > < p > there are two common specifications of gold bricks in the underground vault of the New York Federal Reserve. One is rectangular gold brick, most of which were cast before 1986; the other is trapezoidal in cross section, which is the current standard shape of gold brick. Each brick weighs about 12.5kg. < / P > < p > it is worth mentioning that more than 95% of the BRICs in the New York Federal Reserve’s underground vault are deposited here by foreign governments. For a long time, it’s free to deposit the gold bricks in the underground vault. The New Zealand Federal Reserve only charges $1.75 for each piece when it needs to be moved out of the vault or when the gold bricks need to be changed owners. According to reports, in order to prevent the bricks from accidentally falling and hitting the feet, the porters’ shoes were covered with high-strength magnesium alloy shoe covers. < / P > < p > on weekdays, the underground treasury of the New York Federal Reserve is open to the public free of charge, receiving four batches of 25 visitors each time every day. Visitors need to make an appointment in advance, but due to the small number of places, it is difficult to make an appointment. < / P > < p > the Bank of England vault is the second largest in the world. The Bank of England is the Central Bank of England. It was founded in 1694. In 1734, the Bank of England moved to its current address: a cartoon of the year of needlework in London. The Bank of England got a nickname – “the old lady of needlework Street”. In the cartoon, painter James gerley painted the Bank of England as an old lady covered with pounds. Then British Prime Minister William Pitt proposed to the old lady. < / P > < p > according to public data, about one-fifth of the world’s official gold reserves are held in London, including 5134 tons of gold in the Bank of England’s underground vault. According to the official website of the Bank of England, there are eight underground vaults, which were rebuilt in the 1930s. During the Second World War, British gold was secretly transferred to Canada to avoid falling into the hands of Nazi Germany, and the underground vault of the Bank of England was turned into an air raid shelter. Since the end of World War II in 1945, these eight Treasuries have been used to store gold. < / P > < p > before the 1930s, the hardware and management level of the underground vault of the Bank of England was far from what it is now, and even there were serious loopholes, which almost caused heavy losses. < / P > < p > according to the official website, in 1836, the top management of the Bank of England received several anonymous letters from the same person one after another, claiming that they could easily enter the vault and asked the top management to meet in the vault. The senior management of the bank finally chose to believe the letter writer and wait in the Treasury according to the agreed time. At the appointed time, the bank executives heard some noise under the floor tiles of the vault, and then saw a man come out from under the floor tiles. It turned out that this man was a sewer repairman. In the process of repairing the sewer, he accidentally found the channel leading to the bank vault. Shocked, the bank quickly checked the list of properties in the vault and found that the person did not take anything. The Bank of England rushed to strengthen the vault and awarded the repairman 800. The money is worth about 80000 pounds today and can only buy one seventh of 12.5kg standard gold bricks. < / P > < p > the national treasury of Fort Knox is the third largest in the world. More than half of America’s gold reserves are held here. The Fort Knox vault is not open to the public. In history, only two non Treasury staff were allowed to enter the vault, so the vault is a bit more mysterious. < / P > < p > the Fort Knox vault was founded in 1936 and is under the management of the national mint of the U.S. Treasury. The vault is located in North Central Kentucky, next to the U.S. Army base at Fort Knox. The original intention of building the vault is to transfer the gold that exists in New York, Philadelphia and other cities in the United States here, because the eastern cities are more vulnerable to military attacks from European countries. At its peak in 1941, the vault held 20200 tons of gold. At present, there are about 4582 tons of gold in the Treasury, accounting for 57% of the U.S. gold reserves. < / P > < p > outwardly, the Fort Knox vault is a two-story pyramid like building 13 meters high, 37 meters long at the bottom and 32 meters wide, built of granite and reinforced concrete. What it looks like inside the vault is unknown to the outside world. However, according to an article published on the US Treasury website, the iron gate to the vault is 53 cm thick and 20 tons heavy, and no one has a full set of passwords to enter the vault. In addition to being guarded by heavy troops, the Treasury is also safeguarded by advanced technologies such as high-definition night vision devices. Because the Fort Knox vault is so safe, Americans are used to saying that things or things that are very safe and proper are “as safe as Fort Knox.”. < / P > < p > the Fort Knox vault is strictly forbidden for non staff to enter, with only two exceptions in history. The first time was on September 23, 1974, when it was rumored that the United States had smuggled out the gold bricks in its Treasury and sold them. As for the Treasury, a delegation composed of members of Parliament was allowed to enter the treasury “seeing is believing”. The second time, on August 24, 2017, U.S. Treasury Secretary mu nuqin, then governor Bevan of Kentucky and some congressmen visited the Treasury. < / P > < p > during World War II, in addition to the vast majority of the U.S. gold reserves, the Fort Knox vault also stored some documents and historical materials that the U.S. considered worthy of proper preservation to avoid being destroyed by war, such as the early version of the declaration of independence, the original Constitution of the United States in 1787, and Lincoln’s draft Gettysburg Address in 1863.
