Lesson Introduction
Inflation shapes how households, businesses, and governments experience the economy. It affects purchasing power, savings, wages, and confidence in money itself. While often discussed in technical terms, inflation is a lived reality that influences everyday decisions long before it appears in official statistics.
When inflation rises too quickly, money loses value and trust erodes. When inflation falls too low or turns into deflation, spending slows and economic momentum fades. Both extremes distort behaviour and undermine stability. For this reason, managing inflation is one of the central responsibilities of modern monetary policy.
In this module, we explore what inflation is, how it works, and why it matters. We examine the mechanics that drive inflation, the role of expectations, and why central banks work to keep inflation low and predictable. Using real‑world examples from South Africa and abroad, we also explore what happens when inflation goes wrong and how instability affects households, businesses, and society.
This module is designed for professionals who need a clear, practical understanding of inflation and its impact on economic and financial decision‑making.
