The Ultimate Guide to Inflation: Types, Impacts & Smart Investing
Inflation is a hot topic these days, especially with the economy shifting rapidly and money supply expanding like never before. But what exactly is inflation? Why does it happen? And how can you protect your wealth in an inflationary or deflationary environment? This guide breaks down inflation in simple terms but with expert detail, referencing over 150 years of economic data and insights from financial expert Lynn Alden, as explained by Marco from Whiteboard Finance.
What Is Inflation? Breaking Down the Basics
Understanding Inflation: More Than Just Rising Prices
Inflation is often thought of as the rise in prices for everyday goods — like milk or lumber — but it actually has several layers. The most straightforward definition comes from Merriam-Webster: inflation is a continuing rise in the general price level, usually because there’s more money circulating compared to the goods and services available.
But inflation isn’t just about prices going up; it’s about how money supply, consumer behavior, and economic structures interact over time.
The Three Types of Inflation
1. Monetary Inflation
This is when the total amount of money in the system (often measured as M2, which includes cash, checking accounts, and savings accounts) increases significantly. It’s not about prices directly rising but about more money chasing the same amount of goods and services.
Monetary inflation can happen in two main ways:
- When banks issue more loans, effectively creating new deposits.
- When governments run large deficits and central banks buy government bonds, increasing money supply.
2. Consumer Price Inflation (CPI Inflation)
This is the common inflation we feel daily — when the prices of a broad basket of goods and services rise. It means the purchasing power of the currency is declining. Measuring CPI inflation is tricky, though, because it depends on what goods are included in the basket and how their quality improvements are accounted for (hedonic adjustments).
3. Asset Price Inflation
Asset price inflation happens when the prices of financial assets like stocks, bonds, real estate, gold, and collectibles rise. This is often influenced by low interest rates, which make borrowing cheaper and push investors toward buying assets, boosting their valuations.
The Complexities of Measuring Inflation
What Goes Into the CPI Basket?
Inflation measurement isn’t as simple as tracking prices for a few items. Different households spend money differently — some spend more on housing, others more on transportation or healthcare. This makes creating a “typical” basket challenging.
Plus, technology complicates things. For example, a new car today might cost more than one from 20 years ago, but it comes with far more features. How do we factor in those quality improvements? That’s where hedonic adjustments come in, but they’re often debated.
The Role of Commodity Prices
Prices of commodities like oil, lumber, and metals directly impact inflation since they affect production and transportation costs. When commodities are cheap and abundant, inflation tends to stay low. Scarcity, however, can push prices and inflation up.
Historical Insights: Inflation Over the Last 150 Years
Inflation Patterns Before and After 1971
1971 marked a major shift when the US left the gold standard. Before then, inflation and deflation cycles were more balanced. After 1971, inflationary periods became more dominant, with few deflationary episodes.
Historical data show that inflation spikes often coincide with major wars or economic shocks — World War I, World War II, and the 1970s energy crisis are prime examples.
Case Studies: United States, United Kingdom, Japan, and Australia
- United States: Experienced technological revolutions and huge monetary expansions, especially post-2020 with massive stimulus efforts.
- United Kingdom: Shows tighter correlation between money supply growth and inflation, with fewer natural resources compared to the US.
- Japan: Saw hyperinflation after WWII but has had very low inflation recently despite central bank stimulus, due to low broad money growth.
- Australia: Benefited from China’s rise, seeing faster money supply growth without proportionate CPI inflation at times.
The Impact of Inflation on Everyday Life
Why CPI Might Understate Real Inflation
Many people feel inflation more acutely than official CPI numbers suggest because big-ticket items like housing, healthcare, and education have risen faster than CPI indicates. For example:
- Tuition has increased about 4x since 1990, much faster than overall inflation.
- Housing prices rose roughly 2.8x, while CPI rose about 2x over the same period.
- Healthcare and food prices also tend to outpace CPI.
The Big Mac Test and New Car Prices
The Big Mac index is a fun but insightful way to see inflation — Big Macs have increased in price faster than CPI, closer to the rate of broad money supply growth per person.
Similarly, new car prices have nearly doubled since 1990, but official CPI for new vehicles only shows a 22% increase due to quality and size adjustments.
The “Fiat Hamster Wheel” of Wages and Debt
Wages have barely kept up with inflation, while costs for education and housing have skyrocketed. This leaves many feeling stuck working harder just to maintain their standard of living, often saddled with more debt — a phenomenon called the fiat hamster wheel.
Inflation and Wealth Inequality
Who Gains and Who Loses?
Inflation isn’t just about prices — it shifts wealth dynamics. Those with assets like stocks and real estate (usually the top 10%) tend to benefit more during inflationary periods, especially when money supply growth concentrates wealth at the top. Meanwhile, the bottom 90% see their purchasing power erode, and their debt burdens become more challenging.
Historical Shifts in Wealth Concentration
- In 1990, the bottom 90% held about 40% of US household net worth. Now, that’s closer to 30%.
- The top 10% increased their share from 60% to 70%.
- The top 1% alone hold more wealth than the bottom 90% combined.
Inflation as an Indirect Tax on the Rich?
Interestingly, inflation can act as an indirect tax on the wealthy because it erodes the real value of cash, bonds, and fixed income, which are often held by the rich. Meanwhile, debtors benefit as their liabilities are partially “inflated away.”
The Role of Monetary Velocity and Technology
Velocity of Money: Not the Inflation Driver We Thought
The velocity of money (how fast money circulates through the economy) is commonly blamed for inflation, but data shows it is less correlated with inflation than broad money supply per capita. Money velocity has been declining recently, even as inflation pressures rise.
Technology as a Deflationary Force
Technological improvements generally push prices down. Innovations like smartphones, automation, and globalization have reduced costs for many goods and services. This deflationary pressure has helped keep inflation in check despite rising money supply.
Inflation: Transitory or Persistent?
Transitory Inflation Explained
Often policymakers say inflation is “transitory,” meaning price increases are temporary and will cool down. However, inflation that is only transitory in terms of the rate of change means prices rise quickly and then stabilize at a higher level, not that prices fall back down.
Historical examples from the 1940s and 1970s show inflation often settles at a permanently higher plateau rather than reversing.
Hyperinflation: Why It’s Unlikely Here
What Causes Hyperinflation?
Hyperinflation is extreme price inflation, often defined as 50% month-over-month inflation. It usually occurs in countries that have lost critical wars or collapsed economically, such as Weimar Germany, Zimbabwe, or Venezuela.
Why Developed Countries Are Safer
Developed countries like the US have strong institutions, productive economies, and reserve currency status, making hyperinflation very unlikely under current conditions.
Investing During Inflationary and Deflationary Periods
What Assets Typically Perform Well?
| Asset Class | Inflation Environment | Deflation Environment |
|---|---|---|
| Bonds | Poor | Strong |
| Cash | Poor | Strong |
| Stocks | Mixed (depends on valuations and sectors) | Mixed (good in productive deflation) |
| Real Estate | Generally good (due to leverage effects) | Poor |
| Commodities & Gold | Excellent | Poor |
Sectoral Shifts in Inflation
Value stocks tend to outperform growth stocks during inflationary periods. Rising interest rates put pressure on growth stocks, especially in tech.
Real Estate: A Leveraged Bet Against Inflation
Real estate can do well because inflation erodes mortgage debt, increasing real equity. However, high prices and interest rates can limit gains.
Summing It Up: Navigating Inflation Wisely
Inflation is neither simple nor uniform. It’s a blend of monetary policy, technology, commodity prices, and socio-political changes. Here are the key takeaways:
- Monetary inflation drives increases in money supply, which can translate into consumer price inflation or asset inflation depending on economic conditions.
- Consumer price inflation affects day-to-day life but can be hard to measure precisely due to quality changes and consumption patterns.
- Asset inflation benefits those holding investments, often increasing wealth inequality.
- Technology and globalization have been deflationary forces but may be slowing down.
- Inflation is often transitory in rate of change but not in absolute terms, meaning prices tend not to fall back down once they rise.
- Hyperinflation is rare in developed economies with stable institutions.
- Invest in a diversified portfolio that considers inflation risks, favoring assets like commodities, value stocks, and real estate, while being cautious with bonds and cash.
