For example, in 1971, the U.S. dollar was deducted from the gold standard – the dollar was no longer in gold, and the price of gold was no longer set at one dollar. the health of the U.S. economy supported the value of the dollar. If the economy stalls, the value of the U.S. dollar will decline both domestically due to inflation and internationally through exchange rates. The implosion of the U.S. economy would plunge the world into a dark financial era, so many other countries and entities are working tirelessly to ensure that this never happens. Inflation (%-P) corresponds to the rate of monetary growth (%-M), plus the change in speed (%-V) minus the rate of growth in output (%-Q).  Thus, if, in the long run, the rate of growth in speed and the rate of growth of real GDP are exogenous constants (the first is dictated by changes in payment institutions and the latter dictated by the growth of the economy`s productive capacity), then the rate of monetary growth and the rate of inflation differ by a fixed constant. In the 1930s, Britain had a trading bloc excluding the nations of the British Empire, known as the “sterling zone.” While Britain imported more than it exported to countries such as South Africa, South African sterling beneficiaries tended to put them in London banks.
This meant that Britain had a trade deficit, but it had a financial surplus and payments were balanced. Increasingly, Britain`s positive balance of payments demanded that the wealth of empire nations be kept in British banks. An incentive, say, for South African rand owners to park their assets in London and keep money in sterling was a highly rated pound sterling. In the 1920s, imports from the United States threatened parts of the British domestic industrial goods market and the way out of the trade deficit was to devalue the currency. But Britain could not devalue, or the empire-surplus would leave its banking system.  The relationship between money and prices has historically been associated with the theory of the amount of money. There is strong empirical evidence of a direct link between money supply growth and long-term price inflation, at least a rapid increase in the money supply in the economy.
