Types of Inflation: Meaning, Causes and Consequences

Inflation, far from being a mere statistic, acts as a powerful force reshaping economic terrains. In the United States, for instance, the Consumer Price Index for All Urban Consumers (CPI-U) revealed a 3.4% increase over an unadjusted 12-month period ending April 2024. This figure shines a light on the profound influence of soaring prices on individual consumers. Diving deeper, what exactly constitutes inflation, what are the types of inflation and how do we categorize them?

At its core, inflation signifies a continuous surge in the overall price levels of commodities and services within an economic framework. The calculation of the inflation rate keys in on the average price elevation across a chosen array of products and services in a year. Moreover, it is traditionally segmented into demand-pull, cost-push, and built-in inflation. A profound comprehension of the types of inflation is essential for adeptly manoeuvring the economic field and predicting its future path.

In terms of perception, inflation can engender contrasting viewpoints. Some perceive it as a catalyst that enhances the worth of their assets, while others construe it as an imminent jeopardy to their consumer influence. Nevertheless, inflation seeks to quantify the global effect of price fluctuations on a diverse array of commodities and services. It provides a consolidated index of the upsurge in the price tier of goods and services within an economy during a specific timeframe.

Inflation is a foundational concept in economics, denoting a persistent elevation in general price levels of goods and services within an economy. Over time, it entails the reduction of money’s buying capability amidst escalating living costs. The inflation rate is crucial, marking the pace of this price elevation over defined intervals, usually a year. That is, it demarks the velocity at which consumer price levels are swelling. A higher rate further indicates an accelerated devaluation of currency value.

Measuring the Impact of Price Changes

Inflation is generally assessed using the Consumer Price Index (CPI) and the Producer Price Index (PPI). The CPI delves into the alteration in prices consumers pay for a set basket of goods and services, thus epitomizing variations in the cost of living. On the other hand, the Producer Price Index (PPI) focuses on the pricing changes from the viewpoint of sellers or producers.

The escalation in the prices of various goods and services typically results from a discrepancy between their supply and the demand for them. This imbalance is, therefore, orchestrated by powerful economic catalysts. Inflation unfolds as a consequence of multiple influences, notably demand-pull inflationcost-push inflation, and built-in inflation.

Demand-Pull Inflation

At its core, demand-pull inflation unfolds as more money and credit enter circulation. Furthermore, this influx differs from the economy’s production upsurge. This stimulates an augmented desire for goods and services. Consequently, this surge in demand propels prices upwards.

This situation empowers individuals, also fostering robust consumer positivity, and leading to more spending. Elevated spending, amid a constrained supply scenario, serves as the pivot for escalating prices. Ultimately, this engenders a disparity that reflects a skew towards greater demand than the supply can cater to, hence price inflation.

Amid the COVID-19 crisis, a distinct pattern of inflation emerged globally with pronounced escalations in commodity prices. Many commodities, such as hand sanitisers and masks, witnessed increased prices due to high demand. These elevations also ushered supply distortions. Consequently, inflation witnessed an upsurge, echoing signs of both demand-pull and cost-push inflation.

Collectively, inflation’s genesis often implicates cost-push and demand-pull dynamics. Additionally, it may stem from the influx of money as well as the reduction in money demand.

Cost-Push Inflation

Cost-push inflation manifests as a price surge filtered through the production chain. Notably, severe downturns in key commodities’ availability exacerbate these impacts. Consequently, the costs of intermediary goods escalate, elevating final product/service prices and culminating in a ramp-up of consumer expenditures.

Moreover, an escalation in production expenses diminishes the combined goods and services supply. This shortfall in availability can be traced back to increased raw material and labour expenses, hence, instigating a broader price elevation.

Unforeseen natural calamities, like floods and earthquakes, can introduce an element of abrupt cost-push inflation by disrupting supply chains. Similarly, governmental adjustments, supply shocks and regulatory shifts push up operational expenditures for firms, fostering a climate ripe for cost-push inflation.  For instance, Oil prices in the 1970s inflated due to the Oil embargo because it disrupted the oil supply and also led to stagflation.

The wage-price spiral, intertwined with cost-push inflation, materializes when enhanced remunerations spur demand, thus priming an inflationary loop.

Built-in Inflation

Built-in inflation conjoins with the concept of adaptive expectations, wherein individuals project ongoing inflation rates into the future. This anticipation translates to a presumption of future cost escalations. Consequently, wage increments are sought by employees to uphold their living standards in light of this expected price surge. The ensuing cycle, known as the wage-price spiral, perpetuates, as each stimulation (wage hike or price increase) triggers the other, engendering a self-sustaining loop.

This inflation type, emerges when a history of unremitting demand-pull or extensive cost-push inflation endows it as a customary economic feature. A pivotal attribute delineating this phenomenon is its self-reinforcing nature, seamlessly blending into consumer and producer behaviour, thus amplifying its endurance. Moreover, regulation proves arduous, given its integration within economic stakeholders’ presuppositions and practices.

Inflation MeasureKey Characteristics
Demand-Pull InflationEmerges when consumer demand surpasses goods and services availability, leading to scarcities and price elevations.
Cost-Push InflationIs triggered by increasing production expenses, compelling price adjustments from producers.
Built-in InflationOccurrs within a self-sustaining process of wage increases spurring price escalations, marking an intrinsic cycle.

The Consumer Price Index (CPI) tracks the prices of various goods and services, reflecting shifts in consumer spending. The CPI also stands as the foremost indicator of inflation trends within economies. Correspondingly, the Producer Price Index (PPI) is also useful in assessing the inflation situation. This index measures alterations in the prices that companies or producers charge for their offerings. Significantly, the PPI’s insights are pivotal for firms engaged in long-term contractual agreements.

The Consumer Price Index (CPI)

The Consumer Price Index (CPI) offers a weighted average of essentials’ prices in consumer spending, including needs like transportation, food, and healthcare. It serves the essential role of determining variations in the cost of living and signalling economic upswings or downturns since its inception in 1913.

The Wholesale Price Index (WPI)

Distinct from the retail arena, the Wholesale Price Index (WPI) focuses on precursory price modifications in goods or the wholesale prices of goods. Therefore, this index illuminates how the escalation of one element’s cost can balance out the decrease in another’s, offering a nuanced view.

The Producer Price Index (PPI)

The Producer Price Index (PPI) examines the alterations in the prices received by local producers for their output over time. This index is characterized by its perspective, focusing on the pricing dynamics from the seller’s standpoint. Hence, it is a complementary analysis to the CPI which scrutinizes consumer purchasing power.

The formula for determining the inflation rate is straightforward:

[(Ending Value – Starting Value)/Starting Value] x 100 

The starting value signifies the Consumer Price Index (CPI) from a previous period, whereas the ending value refers to the most recent measure for the same entity. By subtracting these quantities, you discern the CPI’s fluctuation. To ascertain the inflation rate, divide this figure by the starting value, then multiply by 100.

As an illustration, suppose the January 2022 CPI was 100, and in January 2023, it reached 103. Thus, the inflation rate is computed as:

(103 – 100)/100 x 100 = 3%. 

Consequently, prices elevated by 3% within that year.

The Producer Price Index (PPI) index offers additional insights into inflation assessment. The PPI mirrors alterations in how much businesses charge for their offerings. Proficiency in gauging the inflation rate is indispensable for commercial enterprises, decision-makers, and the public alike. This is because it is essential to strategize effectively amidst inflation’s economic consequences.

Inflation manifests across a spectrum from mild to severe impacts, classifying into several types. These variants encompass creeping, walking, galloping, and hyperinflation. Each category also reflects a distinct level of economic strain and consumer disruption.

Types of Inflation

Creeping Inflation

Creeping inflation depicts a subdued, consistent price elevation, typically at a 2-3% annual scale. This incremental ascent within the economy’s price fabric is deemed acceptable, even expected.

Walking Inflation

When inflation picks up to a moderate yet continual tempo, it embodies walking inflation, often observed at 3-10% annually. This scenario can arise from various catalysts, including heightened demand, supply shortages, and elevated production expenses.

Galloping Inflation

Galloping inflation denotes an uncontrollable surge in prices, rising into the double or even triple digits. Its rapid escalation, therefore, poses detrimental effects on purchasing potential and market stability.


At the pinnacle stands hyperinflation, a catastrophic scenario where prices skyrocket, annihilating economic structures. Historical instances, such as Germany in the 1920s and Zimbabwe in 2008, showcase inflation rates exceeding imagination.

Deflation and Inflation are contrasting economic trends fraught with implications for various sectors of society. Inflation manifests as an excessive and rapid escalation in the prices of commodities and services. Conversely, deflation denotes a persistent decline in the broad spectrum of price levels, with the inflation rate dipping below zero per cent.

The central banks endeavour to sustain minor inflation rates, ideally between 2% and 3% annually. Their objective is anchored in the maintenance of price equilibrium and the facilitation of robust economic expansions. Deflation, conversely, initiates a slew of adverse effects, underpinning the potential for economic downturns, constriction in economic advancements, and amplification in joblessness. The protracted deflationary phase experienced by Japan during its “Lost Decade” exemplifies the ruinous ramifications of extended deflation.

To counter the divergent challenges posed by inflation and deflation, central banks wield an arsenal of monetary policy mechanisms, encompassing interest rate manipulation and control over the currency supply. In scenarios of economic turmoil, precipitous price drops also demand immediate intervention to avert a debilitating deflationary cycle. Hence, such efforts involve central banks adjusting the accessibility of credit.

It falls upon policymakers to delicately navigate the perils associated with inflation and deflation in their pursuit of price stability and the stimulation of sustainable economic development. Mastery of the intricate factors and implications of these economic states is essential for making informed policy directives and further preserving economic well-being.

Inflation significantly impacts an economy by reducing the purchasing power of its currency. This leads to each unit buying less goods and services over time.

Effects on Purchasing Power

The impact of inflation on individual and household purchasing power can be profound. As the cost of items increases, less can be obtained with the same amount of money. This compromises people’s ability to uphold their lifestyle. Various factors trigger inflation, including money printing, currency devaluation, or the introduction of new money through the banking sector.

Income Redistribution Effects

Inflation doesn’t affect all socio-economic groups equally, leading to income redistribution. Fixed income earners or those dependent on state support may struggle to match price hikes. Conversely, individuals with assets that gain value with inflation, like property or shares, could see their wealth grow.

Effects on Savings and Investments

Inflation significantly hits both savings and investments. If inflation rates surpass savings interest rates, their real value drops. This issue affects the purchasing power of those funds adversely. Treasury Inflation-Protected Securities (TIPS) are designed to counteract this by adjusting returns to inflation. They offer protection against the depreciating effect of inflation. Additionally, companies may struggle in high inflation periods. They face the dilemma of whether to raise prices, thus impacting consumer buying, or reduce their margins.

Inflation and Interest Rates

Inflation and interest rates are intricately linked, profoundly shaping economic environments. When inflation spikes, central banks adjust interest rates to temper economic growth and stabilize prices. To combat rising inflation, these banks might elevate interest rates. This action increases the cost of borrowing, thus moderating consumer spending and business investments, thereby inhibiting inflationary pressures. Conversely, in times of deflation, central banks might reduce interest rates, pushing borrowing costs down to encourage economic activities.

As the cost of living rises in periods of inflation, a prudent financial approach is to increase your income. This can be achieved by investing in assets that have historically outperformed inflation. Such assets include those that offer high dividends or interest rates, such as fixed-income funds, Treasury bills, tax-free municipal bonds, exchange-traded funds, and mutual funds.

Investing in Inflation-Resistant Assets

Real estate acquisition offers a tangible method to diversify your portfolio and reduce financial risks during downturns. Investments known to resist inflation also serve as a protective shield. For instance, Treasury Inflation-Protected Securities (TIPS) offer protection against inflation by adjusting their premiums based on the inflation rate.

Diversifying Investments

Diversification across various asset categories, including stocks, bonds, real estate, and commodities, is key to inflation protection. By combining investments in assets known to resist inflation with adequate diversification, one can enhance their resilience against the eroding effects of inflation.

Inflation, a fundamental economic concept, implies a persistent increase in general price levels of goods and services. This phenomenon impacts individuals, businesses, and the broader economy. It is imperative to comprehend the different types of inflation. These include demand-pull inflation, cost-push inflation, and built-in inflation. Such knowledge is instrumental in manoeuvring through the complexities of economic change. The Consumer Price Index (CPI) remains a key metric for gauging inflation trends.

Inflation can drastically lower purchasing power, reshuffle income dynamics, and influence savings and investments. Mitigating these effects requires strategic approaches. For example, investing in assets that resist inflation and broadening investment portfolios can mitigate inflation’s corrosive impact.

The recent rise in inflation during the COVID-19 period underscores the critical nature of proactively protecting one’s financial state. By grasping the fundamental causes of inflation and enacting sound fiscal strategies, individuals, governments and corporations can confront inflation’s effects. This approach will enable them to sustain their positions and achieve prosperity in the long run.
