The Nation of Mexico worked within this gap in 1993 by removing three zeros from it's currency. It created a new peso, worth 1,000 of the original one.
Now, 15 years later... the digital financial market of the entire globe is revealed
to be trading (in only one specific economic market)
500 trillion dollars.
The current estimate of the value of all goods and services currently and actually existing right now on Earth is about 60 trillion dollars.
This means (mathematically) that 15 years after Mexico publicly removed three zeros from its physical currency,
the U.S.A. (and as a result, the global financial markets) are exposed for adding three zeros... to legal financial contracts
regarding not physical currency, but rather the obligation to pay in the future...
more often than not by digital transfer of numbers in bank accounts
still not affecting the physical currency.
It remains to be seen what will affect the American Dollar,
which has pretty much always added one zero to the new peso.
The Spanish dollar or Mexican peso was widely used in the early United States. By a decree of July 6, 1785, the value of the United States dollar was set to approximately match the Spanish dollar, both of which were based on the weight of silver in the coins. The first U.S. dollar coins were not issued until April 2, 1792, and the peso continued to be officially recognized and used, along with other foreign coins, until February 21, 1857. In Canada, it remained legal tender, along with other foreign silver coins, until 1854 and continued to circulate beyond that date.  The Mexican peso also served as the model for the Straits dollar, the Hong Kong dollar, the Japanese yen and the Chinese yuan.  The term yuan refers to the round Spanish dollars, Mexican pesos and other 8 reales silver coins which saw use in China during the 19th century.
...On 1 January 1993, the Bank of Mexico introduced a new currency, the nuevo peso ("new peso", or MXN), written "N$" followed by the numerical amount. One new peso, or N$1.00, was equal to 1000 of the obsolete MXP pesos.
As the derivatives business has grown more complex, it has also
ballooned in scale. Broadly speaking, Das - author of a leading
textbook on derivatives and complex securities - estimates that
investors worldwide hold more than $500 trillion worth of
This number now dwarfs the global GDP, which tops out around $60
