Why is there inflation every year?

Inflation is the rate at which the prices for goods and services rise over time. It is a normal part of a healthy economy, but too much inflation can be problematic. There are a few main reasons why there tends to be inflation every year:

Money Supply

One of the basic principles of economics is that inflation occurs when there is too much money chasing too few goods. When there is an increase in the money supply, there is more money available for consumers to spend. However, if the supply of goods and services does not increase at the same rate, it leads to inflation. This is because consumers have more money to spend, which drives up demand, but suppliers cannot increase supply fast enough to meet demand, which pushes prices up.

Central banks like the Federal Reserve have some control over the money supply through monetary policy. Actions the Fed takes, such as lowering interest rates or quantitative easing, put more money into circulation, which often leads to some inflation. Of course, the Fed takes many other factors into account when making policy decisions, but generally speaking, increasing the money supply faster than the supply of goods and services available will lead to inflation.

Rising Wages

As the economy improves and unemployment falls, wages tend to rise. This gives workers more disposable income, increasing their purchasing power and allowing them to spend more. Businesses must then raise prices to maintain their profit margins. Even when overall unemployment is steady, shortages in some industries or regions can cause wages to rise faster than the overall economy, leading to price increases. The pace of wage growth throughout the economy is a major factor the Fed considers when combating inflation.

Rising Input Prices

For businesses, the cost of raw materials, components, transportation, and other operating expenses are key inputs that affect pricing of finished goods and services. When input costs rise, it compresses profit margins for businesses. In response, businesses raise prices to maintain target profitability levels. These input price increases get passed along to consumers in the form of broad-based inflation.

Some common examples include:
– Oil and gasoline prices that rise and fall with global crude oil prices
– Commodities like corn, wheat, metals, etc. thatsee frequent price volatility
– Transportation and shipping costs that can swing significantly

Population Growth

As the population grows over time, demand for goods and services increases. More people means more consumption. If the supply of products cannot increase quickly enough to meet higher demand, prices will rise. The rate of population growth each year is fairly steady, so this contributes to a small, consistent amount of inflationary pressure on an annual basis.

Debt Growth

As total debt levels (public, corporate and consumer debt) increase, it creates upward pressure on prices. This is because higher debt requires increased money supply to service the debt. More money chasing the same amount of goods leads to inflation. Rising interest rates required to service higher debt also increase business costs. This gets built into the cost of finished goods.

Consumer Expectations

Workers expecting inflation will demand higher wages. Consumers expecting products to cost more will be less resistant to price hikes. Businesses raise prices more freely knowing consumers expect it. This cycle of embedded expectations about inflation leads consumers to accept inflation as normal. However, if expectations spiral out of control, it can greatly exacerbate inflationary pressures.

How Inflation is Measured

There are several key metrics used to track inflation:

Consumer Price Index (CPI)

The Consumer Price Index (CPI) is the most well-known measure of inflation. It tracks the average change in prices paid by consumers for goods and services, such as food, housing, transportation, medical care, recreation, apparel, education, etc.

The CPI is calculated each month by the Bureau of Labor Statistics (BLS). A “market basket” of thousands of common consumer purchases is tracked over time. The change in the total price of that basket of goods represents the monthly inflation rate.

CPI is used as a guide to make cost-of-living adjustments for Social Security, pensions, food stamps and other government benefits. It helps economists evaluate whether the economy is improving or not. The Fed uses CPI closely to guide their decisions on interest rates and monetary policy.

Producer Price Index (PPI)

The Producer Price Index (PPI) measures inflation from the perspective of sellers rather than buyers. The PPI tracks changes in the prices received by domestic producers for their output. Thousands of goods and services are tracked to identify price shifts.

PPI often leads CPI, because changes in input prices inevitably force producers to adjust their final output prices for consumer goods. Therefore, PPI can provide an early warning signal of inflation before it impacts consumers.

GDP Deflator

The GDP deflator compares the value of goods and services produced in the economy year-over-year, adjusted for inflation. Nominal GDP measures the total value of all finished goods produced. Real GDP adjusts this for inflation to reflect the actual growth in quantities produced. The GDP Deflator is derived by dividing Nominal GDP by Real GDP.

Unlike CPI, the GDP deflator is not based on a fixed basket of goods. It covers all the goods and services produced domestically. Since it is broader than CPI, it helps economists assess whether inflation is being driven by a specific category of products or is more widespread.

Core Inflation Index

The Core Inflation Index excludes volatile categories like food and energy to identify the underlying rate of inflation. Food and energy prices often swing significantly based on circumstances like weather, natural disasters, global political turmoil, etc. By stripping them out, economists can better see the structural rate of inflation. The Core Inflation Rate gives the Fed a clearer picture of true inflation to set monetary policy.

Employment Cost Index

The Employment Cost Index (ECI) tracks the rate of growth in employee wages and employer benefit costs like health insurance premiums. Rising employment costs are a significant driver of inflation. Monitoring the ECI helps economists see whether inflationary pressures are building as wages escalate faster than productivity.

Impact of Inflation

While a low, stable rate of inflation of 1-3% per year is ideal, higher inflation has detrimental economic effects:

Erodes Consumer Purchasing Power

As prices rise faster than incomes, consumers cannot purchase as many goods and services. Higher inflation makes people feel poorer as their dollars buy less. Discretionary spending typically declines as budgets get tighter, dragging on economic growth.

Discourages Savings

High inflation erodes the return on savings accounts and other fixed income investments. When inflation outpaces interest rates paid to savers, the real purchasing power of the accumulated savings falls over time. This discourages long-term saving and investing.

Benefits Borrowers

Inflation erodes the “real” value of loan payments over time. As wages and prices rise, existing debt becomes easier to payoff. This benefits borrowers but hurts lenders inflation-adjusted returns.

Distorts Price Signals

Rapidly changing prices make it harder for producers and consumers to make informed economic decisions. Volatile prices undermine efficient allocation of resources driven by price signals in a market economy.

Increase Uncertainty

High inflation generates uncertainty about the future, forcing businesses and households to make frequent adjustments in a rapidly changing environment. This makes planning and budgeting for the future difficult.

Devalues Currency

Rising inflation causes a country’s currency to lose purchasing power. This drives down the exchange rate in foreign currency markets as the currency devalues, making imports more expensive. This can create instability in international trade.

Historical Perspective on U.S. Inflation

Inflation has ebbed and flowed significantly throughout U.S. history as seen in the chart below. Some key observations:

  • Periods of high inflation often coincide with major wars that drove up government spending.
  • Inflation peaked during the 1970s energy crisis when oil prices spiked.
  • Federal Reserve policy has kept inflation relatively low and stable since the 1980s.
  • The Great Recession led to a brief deflationary period as economic activity slowed.
Time Period Average Inflation Rate
1774-1860 0.4%
1861-1910 0.6%
1911-1920 7.7%
1921-1930 -1.7%
1931-1940 0.8%
1941-1950 5.5%
1951-1960 2.3%
1961-1970 2.5%
1971-1980 7.4%
1981-1990 5.6%
1991-2000 3.0%
2001-2010 2.6%
2011-2020 1.8%

Predicting Future Inflation Trends

Professional economists have developed models to forecast inflation based on various economic influences:

Phillips Curve Model

The Phillips Curve correlates inflation with unemployment rate. Lower unemployment typically drives faster wage growth, resulting in more inflation. But modern economies have shown uneven linkage between jobs and prices.

Commodities Prices

Swings in commodities prices like oil, grains and metals pass through to producers and consumers. Watching these price futures helps anticipate cost-push inflation effects.

Monetary Indicators

Growth in the money supply, changes to interest rates and other monetary policies indicate inflationary conditions. However, inflation has remained low despite growth in the monetary base over the past decade.

Inflation Expectations

Surveys on consumer and business inflation outlooks provide insight on embedded psychology toward future prices. Expectations can be self-fulfilling and difficult to reset once rooted.

Global Demand

Strong growth in emerging markets creates more competition for limited resources. Rising global middle class consumption also boosts demand. But globalization has allowed companies to shift production to meet demand.

What Determines Ideal Level of Inflation

Most economists today agree the optimal level of annual inflation is around 2% for a healthy economy. This modest inflation offers a number of benefits:

Prevents Deflation

Sustained deflation, or falling prices, stunts economic growth as consumers delay purchases expecting lower future prices. Moderate inflation ensures a buffer against destructive deflation.

Drives Money Velocity

Consumers incentivized to spend money rather than sit on cash that is declining in value. Fosters more transactions and economic activity.

Reduces Real Interest Rates

A low level of inflation allows central banks to maintain lower nominal interest rates, keeping real interest rates negative to stimulate borrowing and investment.

Reduces Unemployment

Moderate inflation empowers the Fed to take more monetary actions, like lower rates, that promote job growth and wage gains for workers. Helps economy operate at full employment.

Manages Debt Levels

As mentioned earlier, modest inflation slowly reduces the burden of public and private debt over time. It makes high debt loads more manageable.

Offsets Measurement Flaws

Inflation metrics like CPI inevitably have flaws. A small inflationary buffer reduces distortions from measurement errors.

How the Federal Reserve Fights Inflation

The Federal Reserve has a dual mandate to promote full employment while maintaining price stability. The main lever it uses to control inflationary pressures is adjusting short-term interest rates. Raising rates slows the economy and fights inflation, while cutting rates stimulates growth at the risk of higher inflation. The Fed has direct tools to modulate interest rates:

Federal Funds Rate

The Fed Funds rate is the interest rate banks charge each other overnight for short term lending. This serves as the baseline for many other interest rates. The Fed sets a target range for Fed Funds and uses open market operations to expand or contract the money supply to hit this target. Higher Fed Fund rates make borrowing and economic expansion more expensive to consumers and businesses.

Discount Rate

This is the interest rate the Fed charges commercial banks for borrowing reserves. By adjusting the discount rate, the Fed makes it more or less expensive for banks to meet reserve requirements and lend money. Higher discount rates tighten money supply and slow inflation.

Reserve Requirements

Banks must hold reserves equal to a percent of customer deposits. The Fed can increase this reserve requirement to restrict lending capacity of banks, tightening money supply. Or it can lower the requirement to allow more lending that increases money supply and inflation.

The Fed also uses forward guidance on the future path of rates, quantitative easing, and other tools to signal policy stances and expectations to the market to steer inflation. But interest rates remain the predominant mechanism used by central banks to fine tune inflationary pressures.

Fiscal Policy Options for Government

The federal government also has fiscal policy options to help manage inflation:

Reduce Government Spending

Lower government expenditures reduce demand for goods and services economy-wide. This alleviates pressure on prices. Targeting less impactful programs helps control inflation with minimal economic disruption.

Increase Taxes

Higher income and sales taxes remove spending power from consumers and businesses, slowing demand. Effective when used sparingly, but taxes that are too burdensome can stifle economic growth.

Tax Relief

The government can also offer tax credits or cuts for necessities like food, clothing and housing. This helps offset rising costs rather than slowing overall consumption. However, lost tax revenue must be addressed.

Price Controls

Setting legal limits for pricing of certain goods has a controversial track record. Often leads to shortages and inefficiencies in allocation of resources. Generally not recommended by economists.

How Consumers Can Protect Themselves

Regular households also have options to shield themselves from inflation:

Lock In Fixed Interest Rates

For large purchases like auto loans or mortgages, locking in fixed borrowing rates prevents inflation from increasing monthly payments. Also protects savers using fixed rate deposits.

Invest in Equities

Stocks and other equities tend to appreciate along with inflation over time. This helps investment portfolios grow faster than the rate of inflation.

Invest in Real Assets

Real assets like commodities, real estate and precious metals hold value better during inflation relative to cash. Adding some real assets can offset inflationary effects on total net worth.

Pursue Higher Wages

Seeking pay raises, finding higher paying jobs and acquiring new skills helps income keep pace with rising prices.

Limit Non-Essential Spending

Carefully monitoring household budgets and reducing unnecessary expenses allows for greater saving and spending on essentials during periods of high inflation.

Conclusion

Inflation is a sustained rise in overall price levels that influences the entire economy. It erodes consumer purchasing power over time but also provides important benefits when maintained at modest levels around 2% a year. Keeping inflation in check requires coordinated monetary policy from central banks with fiscal policy support from governments. Forecasting inflation relies on analysis of key economic metrics and indicators. Wise financial planning by consumers can also help weather higher inflationary environments. Though disruptive in excess, low to moderate inflation is a natural byproduct of a growing economy. Managing expectations and proactive policies are critical to ensure inflation remains under control and supportable.
