US inflation can generally be split into to two periods—before and after the Federal Reserve

Inflation is a monetary phenomenon in which consumers see a broad rise in the prices of goods and services across the economy over time

Sustained periods of inflation are often caused by central bank policies including low interest rates or increased money supply. With more money chasing the same number of goods and services, prices tend to rise and the value of a single dollar drops.

The highest inflation in US history was estimated at 30% in 1778

This was just after the Revolutionary War. Both World Wars also brought double-digit inflation. It's worth noting that exact inflation rates in early America are difficult to calculate precisely.

Central bank independence is correlated with lower inflation on average

Executives may seek to influence the central bank to reduce interest rates for political points. Since its creation in the early 20th century, the US' Federal Reserve saw the most interactions from the president during the Nixon and Ford administrations.

Read former Fed chair Ben Bernanke's 2002 speech about preventing deflation

Very low inflation rates in the early 2000s in the United States and a worsening recession in Japan sparked some domestic concern over the threat of deflation. While Bernanke wasn't Chair at the time of the speech, he emphasized the Fed's role in preventing deflation.

The Federal Reserve targets 2% inflation

It’s an arbitrary number originating from an offhand comment made by a New Zealand policymaker. The real objective is to maintain predictable prices for businesses and families to plan around while avoiding the dangers of deflation.

The Federal Reserve can set interest rates below zero

Interest rates, the cost of borrowing money, are the primary tool the Federal Reserve uses to control inflation. During periods of deflation, setting interest rates below zero penalizes saving, encourages banks to lend more and moves more cash through the economy.

The world's most famous case of deflation happened after Black Thursday

While the details are not fully agreed upon, many economists point to the Federal Reserve's tightening of the money supply as a prime culprit, leading to a significant deflationary spiral.

In the aftermath of the 2008 financial crisis, the Fed began a program of quantitative easing

This program injected trillions of dollars of new money into financial markets to stimulate the economy. The move catalyzed an 11-year bull run and was repeated during the pandemic. Experts argue such power could worsen wealth inequality and contribute to bubbles in housing and finance.

Central banking in the US has had a fraught political history

That history includes its doomed early efforts in the First and Second National Banks, as well as its failure to address the worst financial period in US history, the Great Depression.

Inflation was a word before deflation was

The word inflation has Latin roots and technically means an influx of air, first appearing in the English language in the 1890s to describe bike tires. Deflation's first known mention in an economic text was in 1919.

While the Fed is involved in issuing new generations of cash, the way it adds to the money supply does not involve printers

The majority of money in circulation is credit, not cash. This credit, which acts similarly to direct deposit from employers, is added to bank accounts by the Federal Reserve. The Fed also employs tools like the federal funds rate and open market operations to expand or contract credit.

In the 1970s, the US experienced a period of stagflation

It was characterized by high inflation, slow economic growth, and high unemployment. The crisis was triggered by a combination of factors, including loose monetary policy that spurred excess demand and spiraling oil prices caused by an OPEC embargo in 1973.

President Trump's 2025 Tariffs added less inflationary pressure to the economy than expected in their first year

A year after the so-called "Liberation Day" in April 2025, tariffs have had a milder effect on inflation than feared—core goods prices have added only about 0.2% to the headline Consumer Price Index—but persistent policy uncertainty has rattled small business owners, who say the constant back-and-forth makes long-term planning difficult.

Switzerland's currency is so strong that it could cause deflation

Economic instability in the United States in 2025 strongly benefited Switzerland, where the value of the franc relative to the dollar increased by about 12.7%. In response, the price of imports dramatically decreased, making goods overall much cheaper.

The US dollar has served as the world's reserve currency for 80 years—but is its dominance coming to an end?

Since the establishment of the Bretton Woods economic system, about 90% of global foreign exchange transactions have involved USD. Although no viable alternative exists yet, the dollar's share of central bank reserves has decreased from 73% to 58% from 2001 to 2024, and President Trump's 2025 tariffs have sped up this trend.

The Federal Reserve is the central bank of the US

No institution wields more power in US finance than the Federal Reserve—but opinion polls indicate that most Americans don't know what it does. Curious about the country's central bank? 1440's got your breakdown of how the Federal Reserve works.

Governments have historically used counterfeiting for economic warfare

Inserting fake currency into an economy can help destabilize it. During the American Revolution, for instance, the British distributed counterfeit “Continental Dollars” in an effort to devalue the currency being used in the US at the time with the goal of undermining America’s growing financial credibility. The Nazis also ran an extensive counterfeiting scheme during WWII.

Stablecoins could give people in high-inflation economies access to stronger currencies

Specifically, stablecoins could provide a way to make sure these funds remain valuable during times of volatility. Some examples of people without access to the US dollar using stablecoins as a store of value have been observed in Venezuela.

You can find the value of a dollar dating back to 1635

The value of a dollar hasn’t been consistent throughout history. An inflation calculator lets you compare the value of dollars from any two years over the past four centuries.

The failures of the interwar period made the case for a new international system

After World War I, countries devalued their currencies, raised tariffs to block imports, and seized territory unchecked, with the international community unable to organize effectively to stop them. The result was a global depression and, eventually, another world war.

The US dollar is the most widely circulated currency in the world, and is involved in nearly 90% of global transactions

An inverted yield curve has preceded every recession that’s occurred in the last 50 years

Prolonged yield curve inversions can predict recessions, but even brief inversions can cause investors to react with knee-jerk reactions.

The designs on US coins have changed a lot over the years

From states producing and issuing their own coins after the Revolutionary War, to collectors’ coins in modern times, US coins have had many design changes throughout history. You can learn about the different variations, plus what design elements are added to all US coins today, in an article.

The federal minimum wage in the US has been $7.25 per hour since 2009

While some argue that raising it is essential for reducing poverty, others fear it could lead to inflation and job cuts. The complexity deepens with states setting their own minimum wages—some even below the federal rate—leading to a patchwork of wage laws.

This US Treasury page explains how the federal deficit occurs when annual spending exceeds revenue, shows the current fiscal-year shortfall, and tracks how deficits rise and fall with economic conditions and policy choices.
