Inflation and Deflation

Inflation refers to a general and sustained increase in the price level of goods and services within an economy over time. It is measured by the inflation rate, typically calculated using indices like the Consumer Price Index (CPI). Low inflation usually ranges from 1 to 3%, demonstrating a healthy and growing economy while moderate to high inflation ranges above 3% and hyperinflation will range from 100% and above.

Types of Inflation Statistics and their differences

Types of Inflation

1. Demand-Pull Inflation

A sustained rise in GPL due to an increase in AD. Graphically, there is a rightward shift of the AD curve. As AD rises, production increases causing an increase in scarcity of factor inputs. Firms thus bid up prices of factor inputs causing inflation. This can be caused by factors like increased consumer spending, government spending, or money supply growth. Demand-pull inflation depends on the state of the economy: 

  • Nearer to full-employment equilibrium: Smaller amount of excess production capacity, causing a larger increase in GPL.

  • Further from full-employment equilibrium: Larger amount of excess production capacity, causing a smaller increase in GPL.


2. Cost-Push Inflation:

Sustained rise in the GPL due to a rise in the cost of production. Graphically, ther eis an upward shift of the SRAS curve. Occurs when an increase in production costs leads businesses to raise prices to maintain profit margins, leading to an increase in GPL. This can be caused by factors like higher wages, higher energy prices, or supply chain disruptions.


3. Imported Inflation:

Sustained rise in domestic inflation caused by an increase in the prices of imported goods and service. A rise in the price of imported consumer goods will directly lead to a rise in the GPL. Imported inflation can also lead to cost-push inflation as a rise in the price of imported intermediate goods will cause a rise in the cost of production, leading to a rise in GPL.

Inflation in Singapore context

Recent Trends:

  • Singapore experienced a period of elevated inflation in 2022 and early 2023, with headline inflation peaking at 6.1% and core inflation reaching 5.5% (a 14-year high).

  • This surge was primarily driven by global factors like:

    • Disruptions in global supply chains due to the pandemic.

    • Rising food and energy prices, exacerbated by the Russia-Ukraine war.

  • However, recent trends indicate a moderation in inflation: Core inflation has eased to 3.3% in December 2023, and both headline and core inflation are projected to further decline in 2024.


Key Drivers of Inflation in Singapore:

  • Imported Inflation: Singapore is a highly open economy, making it susceptible to imported inflation from rising global commodity prices and currency depreciation.

  • Domestic Factors: Domestic factors like wage growth, housing costs, and government policies can also contribute to inflationary pressures.


Policy Responses:

The Monetary Authority of Singapore (MAS) closely monitors inflation and utilizes monetary policy tools to manage it:

  • Adjusting Interest Rates: MAS has tightened monetary policy by raising interest rates in 2022 to dampen inflation.

  • Exchange Rate Management: While Singapore maintains a managed float exchange rate, MAS can intervene to influence the Singapore dollar's value and affect import prices.


Consequences of Inflation

Consumers:

  • Reduced Purchasing Power: As prices rise, the value of money decreases, leading to a decline in individuals' purchasing power. This can significantly impact household budgets, particularly for essential goods and services.

  • Increased Cost of Living: Inflation leads to higher prices for everyday items, such as food, housing, transportation, and healthcare, putting a strain on household finances.

  • Erosion of Savings: The real value of savings erodes with inflation, potentially impacting individuals' long-term financial goals and retirement plans.

Producers:

  • Increased Production Costs: Businesses face higher input costs due to rising prices of raw materials, energy, labour, and other factors. This can squeeze profit margins and potentially lead to price increases for consumers.

  • Uncertainty and Reduced Investment: High inflation creates an uncertain economic environment, discouraging businesses from making long-term investments that are crucial for economic growth.

  • Potential for Wage-Price Spiral: If inflation expectations become entrenched, workers might demand higher wages to keep pace with rising prices. This can lead to businesses raising prices further, creating a self-fulfilling inflationary cycle.

Governments:

  • Reduced Tax Revenue: As inflation erodes the value of money, government tax revenues might decline, limiting resources for public services and infrastructure development.

  • Increased Social Spending: Inflation can lead to increased demand for social safety nets and welfare programs, putting additional pressure on government finances.

  • Public Discontent and Political Instability: High inflation can lead to public dissatisfaction with the government's economic management, potentially triggering social unrest and political instability.


Stagflation

This is an economic situation where inflation and economic stagnation occur simultaneously and remain unchecked for a period of time. 

Several factors can trigger stagflation:

  • Supply Shocks: Sudden disruptions to essential goods and services, such as oil price shocks or natural disasters, can drive up prices while hindering economic activity. Imagine a major oil crisis causing fuel prices to skyrocket, leading to transportation disruptions and increased production costs across various industries.

  • Wage-Price Spiral: This self-fulfilling cycle occurs when workers demand higher wages to keep pace with inflation, prompting businesses to raise prices further to maintain profit margins. This creates a vicious loop where inflation fuels wage demands, and higher wages push prices even further.

  • Loose Monetary Policy: Excessive money supply growth can fuel inflation without necessarily stimulating economic growth, potentially contributing to stagflation. Imagine printing too much money, leading to an overabundance of currency without a corresponding increase in the production of goods and services, ultimately driving up prices.


Deflation

Deflation refers to a general and sustained decrease in the price level of goods and services within an economy over time. It can be a concerning phenomenon as it can lead to economic stagnation and recession.

Causes of Deflation:

  • Decreased Aggregate Demand: A decline in consumer spending, investment, or government spending can lead to excess supply and falling prices.

  • Debt Burden: High levels of debt can discourage spending and investment, further contributing to deflationary pressures.

  • Tight Monetary Policy: Central banks raising interest rates can reduce money supply and dampen economic activity, potentially leading to deflation.


Consequences of Deflation

Benefits:

  • Rise in real value of savings: Reduced real value of debt

  • Rise in next exports: Falling prices make exports cheaper for foreigners, increasing the demand for exports

Costs:

  • Discouraged Spending and Investment: Falling prices create an expectation of further price declines, discouraging consumers and businesses from spending and investing.

  • Debt Burden Worsens: As prices fall, the real value of debt increases, making it more difficult for borrowers to repay their debts.

  • Economic Stagnation and Recession: Deflation can lead to reduced production, job losses, and a downward spiral in economic activity.
