<p>Fiat money is currency that has value because a government says it does. No gold, silver, or other commodity backs it.</p>
<p>For several decades, the U.S. dollar has been fiat money. The Federal Reserve writes that its notes “<a href="https://www.federalreserve.gov/faqs/currency_12770.htm">are not redeemable in gold, silver, or any other commodity.</a>”</p>
<p>This guide explains what fiat money is and where the name comes from. It shows what backs the dollar today, using the Fed’s own weekly report. It also explores how the U.S. dollar became fiat money, and the disadvantages and advantages that come with that.</p>
<h2>What Is Fiat Money?</h2>
<p>Fiat money is currency that a government issues that is not tied to a physical good. Its value comes entirely from the law and public trust, not the material it is made of.</p>
<p>Three traits characterize fiat money:</p>
<ul>
<li><strong>A government issues it.</strong> In the U.S., the Federal Reserve issues paper notes and the U.S. Mint makes coins.</li>
<li><strong>The law makes it legal tender.</strong> It counts as valid payment for debts and taxes.</li>
<li><strong>You can’t trade it in for a commodity.</strong> A dollar buys goods, but no one will swap it for a set weight of gold.</li>
</ul>
<h3>Fiat Money Examples</h3>
<p>Nearly every national currency today is fiat money. Examples include the U.S. dollar, the euro, the Japanese yen and the British pound.</p>
<p>With the popularization of bitcoin, some investors wonder if it qualifies as fiat currency. The answer is no. No government produces bitcoin, so it is not a fiat currency. If you’re interested in bitcoin’s relationship with gold, our guide on <a href="https://www.moneymetals.com/news/2025/03/12/why-bitcoin-is-not-equal-to-gold-003904">why bitcoin is not the same as gold</a> explores that question in detail.</p>
<h2>Why Is It Called Fiat Money?</h2>
<p>“Fiat” is a Latin word that means “<a href="https://www.etymonline.com/word/fiat">let it be done</a>.” In the Vulgate Bible, Genesis famously says, <em>fiat lux</em>, or “Let there be light.” Medieval rulers used it to open their proclamations and commands. English speakers have used the word since the 1630s. By 1750, it also meant “a decree” or “an order.”</p>
<p>That means that fiat money is literally money by decree. Its value starts with an order issued by the state, not a metal. <a href="https://www.merriam-webster.com/dictionary/fiat">Merriam-Webster</a> lists several ways to say the word, with the first being FEE-uht.</p>
<p>The opposite of fiat money is commodity money. That is money made of something with intrinsic value. Historically, this has often meant gold or silver coins. These are referred to as <a href="https://www.moneymetals.com/news/2023/08/17/specie-money-the-forgotten-currency-002797">specie money</a>, and they are the most common examples of commodity money.</p>
<h2>Is the U.S. Dollar Fiat Money?</h2>
<p>Yes. Federal law is what makes the dollar money. Under <a href="https://www.law.cornell.edu/uscode/text/31/5103">31 U.S.C. 5103</a>, U.S. coins and currency, including Federal Reserve notes, “are legal tender for all debts, public charges, taxes, and dues.”</p>
<p>The law does not promise metal in return. The Fed says its notes <a href="https://www.federalreserve.gov/faqs/currency_12770.htm">have not been redeemable in gold</a> since January 30, 1934. They have not been redeemable in silver since the 1960s. A dollar is legal tender because Congress says so. It is fiat money because you can’t turn it in for gold or silver.</p>
<h2>What Backs the U.S. Dollar Today?</h2>
<p>Congress requires the Fed to hold collateral equal in value to the notes it puts into circulation. <a href="https://www.federalreserve.gov/faqs/currency_12770.htm">The Fed says</a> this collateral is “chiefly held in the form of U.S. Treasury, federal agency, and government-sponsored enterprise securities.”</p>
<p>The Fed reports this collateral every week in Table 7 of its <a href="https://www.federalreserve.gov/releases/h41/current/">H.4.1 release</a>. Here is what stood behind Federal Reserve notes on October 14, 2026:</p>

<p><em>Source: <a href="https://www.federalreserve.gov/releases/h41/current/">Federal Reserve H.4.1, Table 7</a>, released October 15, 2026. Shares are rounded.</em></p>
<p>In plain terms, the dollar is backed mostly by government debt. About 99 cents of every collateralized dollar is Treasury, federal agency, or mortgage-backed securities. Other collateral includes special drawing rights, a reserve asset created by the International Monetary Fund. Finally, there’s gold, which represents a sliver of the total collateral assets.</p>
<p>The week of October 14, 2026, the Fed had $2.84 trillion in notes outstanding. About $398 billion sat at Federal Reserve Banks. Those notes do not need collateral.</p>
<h3>Is the U.S. Dollar Backed by Gold?</h3>
<p>The U.S. dollar is no longer backed by gold. Gold certificates make up less than half of 1 percent of the collateral behind Federal Reserve notes. Moreover, collateral is not the same thing as a claim.</p>
<p>When the dollar was tied to gold under the gold standard, your bank note acted as a receipt. You could exchange it at any time for that note’s requisite weight in gold. That is what it means to have your currency backed by gold.</p>
<p>Now, holding a dollar gives you no right to trade it for that gold.</p>
<h3>How Does Fiat Money Have Value?</h3>
<p>Since you cannot redeem a dollar for gold or silver, why does a dollar buy anything? Three things answer that question:</p>
<ol>
<li><strong>The law.</strong> Dollars are legal tender for debts and taxes. Anyone who owes federal taxes needs these dollars.</li>
<li><strong>Trust.</strong> People accept dollars because they expect others to accept them too.</li>
<li><strong>Supply control.</strong> The Fed manages how much money exists. When the <a href="https://www.moneymetals.com/news/2025/06/30/money-supply-expansion-this-is-inflation-004158">money supply grows</a> faster than the economy, each dollar tends to buy less.</li>
</ol>
<h2>How the U.S. Moved to Fiat Money</h2>
<p>The U.S. did not adopt a fiat system in a single step. Several things happened that gradually loosened the dollar’s ties to gold.</p>
<p>The first step took place in 1933. That year, President Franklin Roosevelt signed <a href="https://www.moneymetals.com/news/2024/05/15/understanding-roosevelts-1933-gold-confiscation-003194">Executive Order 6102</a>. That order required Americans to turn in their gold for a compensation of $20.67 per ounce. There were exemptions carved out for gold coins with numismatic value, as well as allowing people to keep $100 in gold coins.</p>
<p>Congress then passed the <a href="https://www.federalreservehistory.org/essays/gold-reserve-act">Gold Reserve Act</a> on January 30, 1934. It moved all monetary gold to the Treasury and raised the official price from $20.67 to $35 an ounce. After that, Americans could not redeem notes for gold. Silver remained in everyday use as currency until 1965. That year, the Coinage Act of 1965 ended silver’s use in most coins, with an exception for the half dollar.</p>
<p>The final step came in 1971, when President Richard Nixon closed the “<a href="https://www.federalreservehistory.org/essays/gold-convertibility-ends">gold window</a>” that allowed foreign governments to trade dollars for gold. With that connection severed, the gold standard was effectively over.</p>
<h2>The First Fiat Money</h2>
<p>Fiat money is far older than the dollar. Marco Polo saw it in China in the late 1200s. He described how Kublai Khan “<a href="https://historyofinformation.com/detail.php?id=243">causes all payments on his own account to be made</a>” in paper notes.</p>
<p>If any of Polo’s readers wondered how people could accept such a strange system, he gave them a clear explanation: “nobody, however important he may think himself, dares to refuse them on pain of death.”</p>
<p>Those two lines sum up fiat money. It is a decree from a government with the power to enforce it. Polo wrote that explanation roughly 700 years before Nixon closed the gold window.</p>
<p>America’s own first test came in 1690. That year, the Massachusetts Bay Colony issued paper money with no metal behind it. <a href="https://www.moneymetals.com/news/2022/02/03/americas-first-experiment-with-paper-fiat-money-002470">It did not go well</a>.</p>
<h2>Commodity vs. Representative vs. Fiat Money</h2>
<p>Money comes in three basic types.</p>

<p>Fiat money and paper money are not the same thing. A paper note is representative money if you can trade it for metal. And most fiat money today is not paper at all. It exists as numbers in bank accounts.</p>
<p>The <a href="https://www.federalreserve.gov/releases/h6/current/default.htm">M2 money supply</a> was about $20.0 trillion in August 2026. Federal Reserve notes outstanding totaled about <a href="https://www.federalreserve.gov/releases/h41/current/">$2.84 trillion</a> in mid-October. Some of those sat in Fed vaults. Paper cash is only a small slice of U.S. money.</p>
<h2>Pros and Cons of Fiat Money</h2>
<h3>Pros</h3>
<p>The Federal Reserve Bank of St. Louis makes the case for fiat money in a short video. Under a gold standard, a bank run can drain a bank’s gold.</p>
<p>Economist David Andolfatto explains the fiat fix: “Under a fiat money system, the government is free to create money and to lend it out temporarily to these distressed banks.” Once people see they can get their money, he says, the panic fades.</p>
<ul>
<li><strong>Flexible supply.</strong> The central bank can add money during a crisis.</li>
<li><strong>No mining limit.</strong> The money supply does not depend on how much gold is dug up.</li>
<li><strong>Fewer bank runs.</strong> Banks can’t run out of gold, because notes don’t promise gold.</li>
</ul>
<h3>Cons</h3>
<ul>
<li><strong>Lost buying power.</strong> The same St. Louis Fed video states the critics’ view. When more dollars enter circulation, “<a href="https://www.stlouisfed.org/timely-topics/the-gold-standard/videos/part-4-benefits-of-a-fiat-money-system">the value of each dollar drops, driving prices up.</a>”</li>
<li><strong>It depends on trust.</strong> Its value rests on public confidence and on choices made by officials.</li>
<li><strong>No hard limit.</strong> Nothing physical caps how much money can be created.</li>
</ul>

<h5 class="text-2xl mt-8">The Bottom Line</h5>
<p>Fiat money is money issued by decree. The law determines this money is legal tender. Government debt makes up nearly all the collateral behind it. Gold is less than half of one percent of its backing, and you cannot claim that gold.</p>
<p>In contrast, gold and silver were the heartbeat of commodity money. Their value does not depend on a decree.
