Because of the global nature of trade, parties often need to acquire foreign currencies as well. Governments have two basic policy choices when it comes to managing this process. The first is to offer a fixed exchange rate. Here, the government pegs its own currency to one of the major world currencies, such as the American dollar or the euro, and sets a firm exchange rate between the two denominations.
The main goal of a fixed exchange rate is to create a sense of stability, especially when a nation's financial markets are less sophisticated than those in other parts of the world. Investors gain confidence by knowing the exact amount of the pegged currency they can acquire if they so desire.
However, fixed exchange rates have also played a part in numerous currency crises in recent history. This can happen, for instance, when the purchase of local currency by the central bank leads to its overvaluation. The alternative to this system is letting the currency float. Instead of pre-determining the price of foreign currency, the market dictates what the cost will be. The United States is just one of the major economies that uses a floating exchange rate.
In a floating system, the rules of supply and demand govern a foreign currency's price. Therefore, an increase in the amount of money will make the denomination cheaper for foreign investors.
And an increase in demand will strengthen the currency make it more expensive. Suppose the dollar gained value against the yen. Suddenly, Japanese businesses would have to pay more to acquire American-made goods, likely passing their costs on to consumers. This makes U. Most of the major economies around the world now use fiat currencies. While this provides greater flexibility to address challenges, it also creates the opportunity to overspend. The biggest hazard of printing too much money is hyperinflation.
With more of the currency in circulation, each unit is worth less. While modest amounts of inflation are relatively harmless, uncontrolled devaluation can dramatically erode the purchasing power of consumers. Naturally, it becomes harder to maintain the same standard of living.
For this reason, central banks in developed countries usually try to keep inflation under control by indirectly taking money out of circulation when the currency loses too much value. Regardless of the form it takes, all currency has the same basic goals. It helps encourage economic activity by increasing the market for various goods. And it enables consumers to store wealth and therefore address long-term needs.
Currency was once limited to the domain of physical coins and bills, but today's digital economy means that money now exists as data stored in ledgers at banks, and is even transcending the possibility of tangibility with the development of cryptocurrencies such as Bitcoin which can never be made physical.

When the central bank buys these government securities, it puts money into the marketplace, and effectively into the hands of the public.
How does a central bank such as the Fed pay for this? As strange as it sounds, the central bank simply creates the money and transfers it to those selling the securities. To shrink the money supply, perhaps to reduce inflation, the central bank does the opposite and sells government securities.
The money with which the buyer pays the central bank is essentially taken out of circulation. Keep in mind that we are generalizing in this example to keep things simple. A central bank cannot print money without end. If too much money is issued, the value of that currency will drop consistent with the law of supply and demand. Remember, as long as people have faith in the currency, a central bank can issue more of it.
But if the Fed issues too much money, the value will go down, as with anything that has a higher supply than demand. Therefore, the central bank cannot simply print money as it wants.
In the 17th century, Great Britain was determined to keep control of both the American colonies and the natural resources they controlled.
To do this, the British limited the money supply and made it illegal for the colonies to mint coins of their own. Instead, the colonies were forced to trade using English bills of exchange that could only be redeemed for English goods. Colonists were paid for their goods with these same bills, effectively cutting them off from trading with other countries.
In response, the colonies regressed to a barter system using ammunition, tobacco, nails, pelts, and anything else that could be traded. Colonists also gathered whatever foreign currencies they could, the most popular being the large, silver Spanish dollars. These were called pieces of eight because, when you had to make change, you pulled out your knife and hacked it into eight bits.
From this, we have the expression "two bits," meaning a quarter of a dollar. Massachusetts was the first colony to defy the mother country. In , the state minted its own silver coins including the Oak Tree and Pine Tree shillings.
The state circumvented the British law stating that only the monarch of the British empire could issue coins by dating all their coins in , a period when there was no monarch. In , Massachusetts also issued the first paper money calling it bills of credit. Tensions between America and Britain continued to mount until the Revolutionary War broke out in The colonial leaders declared independence and created a new currency called Continentals to finance their side of the war. Unfortunately, each government printed as much money as it needed without backing it to any standard or asset, so the Continentals experienced rapid inflation and became worthless.
This experience discouraged the American government from using paper money for almost a century. The chaos from the Revolutionary War left the new nation's monetary system a complete wreck. Most of the currencies in the newly formed United States of America were useless. The problem wasn't resolved until 13 years later in when Congress was granted constitutional powers to coin money and regulate its value. Congress established a national monetary system and created the dollar as the main unit of money.
It took years to get all the foreign coins and competing for state currencies out of circulation. Bank notes had been in circulation all the time, but because banks issued more notes than they had coin to cover, these notes often traded at less than face value. Eventually, the United States was ready to try paper money again.
In the s, the U. These were called greenbacks because their backs were printed in green. The government-backed this currency and stated that it could be used to pay back both public and private debts. The value did, however, fluctuate according to the North's success or failure at certain stages in the war. Confederate dollars, issued by the seceding states during the s, followed the fate of the Confederacy and were worthless by the end of the war.
In February , the U. Congress passed the National Bank Act. This act established a monetary system whereby national banks issued notes backed by U. The U. Treasury then worked to get state bank notes out of circulation so that the national bank notes would become the only currency.
During this period of rebuilding, there was debate over the bimetallic standard. Some advocated using just silver to back the dollar, others advocated for gold.
The situation was resolved in when the Gold Standard Act was passed, which made gold the sole backing for the dollar. This backing meant that, in theory, you could take your paper money and exchange it for the corresponding value in gold. In , the Federal Reserve was created and given the power to steer the economy by controlling the money supply and interest rates on loans.
Money has changed substantially since the days of shells and skins, but its main function hasn't changed at all. Regardless of what form it takes, money offers us a medium of exchange for goods and services and allows the economy to grow as transactions can be completed at greater speeds.

But how does that relate to American economics since there is no "cashing out" procedure.
If the government gave everyone a bunch more money, there is no "checks and balances" since no one, at the end of the day, goes to the cashier station and exchanges their "chips" money in this case for something of value. Exchanging your chips at the end of the day for MONEY back which has value in our eyes makes sense, hence why you can't give out more chips than the money you have in the vault. But it seems the American dollar is not a paper representation of the "money in the vault" no one goes to cash in their money in America.
So I don't understand how currency works and why we can't just print more money since it really isn't representative of anything of value. Let me try to remove some of the confusion. Now suppose the government simply prints more dollar bills and gives you and imagine everyone else an additional hundred dollars.
If you want to eat more than lbs of corn a month, now you can do so but presumably, since others like you also want to do the same, the demand for corn in the economy would go up and very likely its price as well. This, roughly speaking, is inflation, and it is eroding the real value of your dollars -- you are getting less corn for every dollar than you used to. You ask, won't firms rush to meet this extra demand caused by everyone having an extra hundred dollars? Yes, they would but they'd have to hire people to work in the farms and the higher demand for workers would likely raise their wage.
Also, workers will see the inflation around them and want higher dollar wages so they can continue to buy as much corn as before.
