Understanding the origins and mechanisms of inflation

Context and definition

Why are prices constantly rising? This question concerns every citizen. The answer lies in a fundamental economic phenomenon: the weakening of a currency's purchasing power. Inflation represents the sustained and widespread increase in the price level in an economy. Unlike simple temporary fluctuations, it is characterized by a lasting progression affecting the majority of goods and services available on the market.

This phenomenon is not new. Your grandparents will tell you how a franc used to buy much more than it does today. This monetary erosion is at the very heart of what inflation truly is. Governments track these variations annually, generally expressed as a percentage change compared to the previous period.

The Roots of Inflation: An In-Depth Analysis

The fundamental mechanisms

Two major factors explain the causes of inflation at the elementary level. First, the rapid increase in the money supply in circulation leads to an oversupply of liquidity. Historically, in the 15th century, the massive influx of gold and silver from the Americas destabilized European markets, generating significant inflation.

Then, a shortage of a highly demanded good creates an asymmetry: prices rise for this product, and then this increase spreads to the rest of the economy. The result: a widespread increase in costs affecting all economic sectors.

The three forms of causes of inflation

Demand-pull inflation

This is the most common manifestation. It emerges when overall consumption exceeds productive capacity. Let's imagine a baker producing a thousand loaves of bread weekly. If suddenly the demand triples – because the economic context has improved and consumers have more income – what happens?

The ovens and staff are operating at full capacity. Productive expansion takes time. In the meantime, the shortage of bread creates competition among buyers. Some are willing to pay more. The baker raises his price. Multiplied across all economic sectors, this phenomenon generates widespread inflation: people are buying more products, exceeding the existing supply, which drives prices up everywhere.

Cost-Push Inflation

This mechanism works differently. Operational costs are rising, pressuring companies to pass this increase onto consumers, regardless of demand.

Let's return to our bakery now capable of producing four thousand loaves of bread per week. The balance of supply and demand seemed to be reached. However, a poor wheat harvest creates a shortage. The baker now pays more for this raw material. In the face of these additional expenses, he raises his selling prices despite the absence of an increase in demand.

A similar scenario arises when the government raises the minimum wage: operating costs increase, forcing businesses to pass on this burden. On a macroeconomic scale, this cause of inflation often stems from resource shortages ( oil, minerals ), increases in government taxation, or depreciation of exchange rates making imports more expensive.

Built-in or inertia inflation

Less visible but just as insidious, this form arises from past economic activity. It is rooted in inflationary expectations: after periods of rising prices, employees and companies expect it to persist.

Workers demand higher wages to protect their wealth. Employers, seeing their costs rise, increase their prices. This wage-price spiral creates a self-sustaining cycle: each side pulls at the rope, fearing to be disadvantaged, which accelerates inflation. Workers demand even more wage increases in response to rising costs, perpetuating the process.

Mastery and Adjustment Strategies

The increase in interest rates

When inflation becomes a concern, monetary authorities generally respond by raising interest rates. A more expensive loan becomes less attractive for businesses and households. Consumers cut back on their spending, decreasing demand. Saving suddenly becomes appealing for those who earn interest. This contraction in spending theoretically slows down inflationary pressure.

However, this instrument has drawbacks: economic growth can suffer if businesses and individuals refrain from borrowing to invest or consume.

Alternative budget policies

Although less frequently employed than monetary measures, budgetary policies offer an additional option. Governments can increase taxation on income, thereby reducing the available purchasing power. Less money in the hands of citizens means less demand in the market, theoretically easing inflation.

This approach remains delicate: public opinion often reacts negatively to tax increases. Moreover, effectiveness heavily depends on the economic context.

The role of central banks

Issuing institutions like the U.S. Federal Reserve can alter the supply of fiat currency. Quantitative easing (asset purchases to inject liquidity) exacerbates inflation and therefore does not intervene during inflationary periods. Its opposite, quantitative tightening, reduces the money supply but shows limited effectiveness in practice.

How to Measure Inflation: Indices and Calculations

The first step in combating inflation is to quantify it. This is done through the tracking of specialized indices. The consumer price index (CPI) remains the benchmark instrument in many nations.

The CPI aggregates the prices of a wide range of consumer products using a weighted average, creating a representative basket of household purchases. This measure is repeated regularly, allowing for easy temporal comparisons. In the United States, the Bureau of Labor Statistics collects this data from businesses across the country to ensure accuracy.

Let's assume an IPC score of 100 in the reference year. Two years later, this same index reaches 110. The conclusion: prices have increased by 10% over this period.

The Two Faces of Inflation: Advantages and Disadvantages

The benefits of moderate inflation

Stimulus to spending and investment

Low inflation encourages spending and borrowing. Acquiring an asset today becomes wiser than tomorrow: cash will lose its future value. This dynamic stimulates the circulation of money.

Improvement of commercial margins

Inflation is pushing companies to raise their prices. If this increase is deemed justifiable, many take the opportunity to boost their margins, thereby inflating profits beyond mere inflationary compensation.

Superiority over deflation

Deflation – a lasting decrease in prices – creates an inverse logic: waiting until tomorrow to buy cheaper. This caution dampens demand, reducing economic activity. Historically, deflationary periods have experienced high unemployment and a preference for saving. While saving can benefit the individual, deflation hinders macroeconomic growth.

The major dangers and disadvantages

Monetary Erosion and Hyperinflation

The absence of inflation control wreaks havoc. Inflation erodes wealth: one hundred thousand euros saved today will not have the same purchasing power a decade later. Hyperinflation – an increase of over 50% monthly – becomes catastrophic: a product that cost 10 euros the previous week suddenly costs 15. These increases quickly surpass the simple 50% monthly, distorting the currency and paralyzing the economy.

Economic instability and paralysis

High rates create uncertainty. Citizens and businesses, unaware of the economic trajectory, adopt a defensive stance, reducing investments and spending. Growth suffers from this caution.

Philosophical contestation

Some oppose government intervention, favoring market mechanisms. They denounce the ability of states to “create money,” seeing this as a violation of natural economic principles.

Conclusion

Inflation represents an inevitable facet of contemporary economies based on fiat currency. Its manifestations – rising cost of living, erosion of purchasing power – are felt universally. Far from being intrinsically bad, controlled inflation can even be beneficial for economic dynamics.

The true cause of inflation lies in this delicate balance between supply, demand, expectations, and money supply. Modern governments, armed with adjustable fiscal and monetary policies, attempt to navigate these turbulent waters. Their success depends on caution: a hasty or poorly calibrated implementation could inflict further damage.

Inflation, when well understood and properly regulated, remains an acceptable economic mechanism. Its lack of control, on the other hand, remains one of the major threats to collective financial stability.
