How Inflation Affects Population Purchasing Power
Inflation, characterized by a persistent rise in prices for goods and services, significantly undermines the purchasing power of populations by diminishing the real value of money. Between 2020 and 2025, global and regional inflation, fueled by economic disruptions, supply chain issues, and geopolitical tensions, has reduced consumers’ ability to afford necessities.
Defining Purchasing Power and Inflation
Purchasing power measures how much a unit of currency can buy in goods and services. Inflation erodes this by increasing prices, often outpacing income growth. The Consumer Price Index (CPI) tracks inflation, while real income—nominal income adjusted for inflation—reflects purchasing power changes. Global inflation jumped from a 2010–2019 average of 3.8% to 7.0% in 2022, per the World Bank. In Russia, inflation hit 9.52% in 2024, well above the Central Bank’s 4% target, straining household budgets.
Low- and middle-income groups, who allocate a higher share of income to essentials like food and utilities, are hit hardest by inflation’s effects.
How Inflation Reduces Purchasing Power
1. Escalating Costs of Essentials
Inflation disproportionately affects necessities. In Russia, food, comprising 38.1% of the CPI basket, saw price increases of 10–25% in 2025 due to harvest failures and import barriers. Globally, food inflation reached 13% in 2022, per the Food and Agriculture Organization, limiting access to basic goods.
2. Wages Failing to Keep Pace
When inflation exceeds wage growth, real incomes shrink. In Russia, nominal wages in some sectors rose 20–30% in 2025 due to labor shortages, but real wages, adjusted for 9.52% inflation, grew only 5–10%. In the EU, real wages declined 2.4% in 2022 as inflation outstripped nominal increases, per Eurostat.
3. Higher Borrowing Costs
To combat inflation, central banks raise interest rates, increasing loan costs. Russia’s Central Bank set a 16% key rate in 2025, elevating mortgage and credit rates, which reduced disposable income. In the U.S., Federal Reserve rate hikes to 4.5% in 2023 raised consumer loan rates, constraining household spending.
4. Devaluation of Savings
Inflation erodes savings when deposit rates lag behind price increases. In Russia, 2025 deposit rates of 7–8% fell below 9.52% inflation, reducing savings’ real value. Globally, negative real interest rates in 2021–2023 diminished the purchasing power of savings for many households.
5. Widening Inequality
Vulnerable groups, including low-income households and pensioners, face severe impacts. In Russia, pension adjustments of 8–10% in 2024 trailed inflation, cutting retirees’ purchasing power by 5%. In developing countries, 12% food inflation in 2023 drove 70 million into poverty, per the World Bank.
Regional Effects on Purchasing Power
Russia
Russia’s inflation, peaking at 11.9% in 2022, eroded purchasing power, particularly for food and energy. In 2024, 60% of low-income households reduced non-essential spending, per Rosstat. Sanctions-driven ruble depreciation increased import costs, further pressuring budgets.
USA and EU
In the U.S., 8% inflation in 2022 cut real disposable income by 1.8%, per the Bureau of Labor Statistics, leading 40% of households to dip into savings or borrow. In the EU, 40% energy inflation and 13.8% food inflation in 2022 caused a 3% drop in real consumption, per Eurostat.
Developing Economies
High food and fuel inflation (15% in 2023) in Africa reduced purchasing power, with 20% of households cutting meals, per the African Development Bank. Currency devaluation in nations like Nigeria worsened import costs, slashing real incomes by 10–15%.
Statistical Overview
The table below highlights inflation and real wage growth, showing purchasing power trends:
| Year | Russia Inflation (%) | Russia Real Wage Growth (%) | USA Inflation (%) | EU Inflation (%) |
|---|---|---|---|---|
| 2020 | 4.9 | 2.1 | 1.2 | 0.7 |
| 2021 | 5.8 | 1.5 | 7.0 | 2.6 |
| 2022 | 11.9 | -2.0 | 8.0 | 8.4 |
| 2023 | 7.4 | 1.8 | 4.1 | 5.4 |
| 2024 | 9.52 | 0.5 | 3.0 | 2.5 |
| 2025 (est.) | 7.0–8.0 | 1.0–2.0 | 2.3 | 2.0 |

Mitigating Inflation’s Impact
Households
Consumers can counter inflation by prioritizing essential spending, seeking budget-friendly retailers, and exploring higher-yield investments. In Russia, 25% of households turned to discount stores in 2024 to manage rising costs.
Governments and Central Banks
High interest rates, like Russia’s 16% key rate, aim to control inflation but may limit purchasing power temporarily. Targeted subsidies can help, as seen in the EU’s €10 billion energy subsidy program in 2023 to ease household burdens.
Businesses
Businesses face the choice of absorbing costs or raising prices. In Russia, small firms increased prices by 15% in 2024 to maintain profitability, while larger companies diversified suppliers to stabilize costs.
Long-Term Consequences
Prolonged inflation threatens living standards, widens inequality, and slows economic growth. In Russia, high inflation could reduce real incomes by 5–10% by 2026 if wage growth remains sluggish. Globally, the IMF forecasts inflation stabilizing at 3–4% by 2027, but vulnerable groups will face ongoing challenges.
Policymakers must prioritize wage indexation and support for low-income households, while consumers and businesses adapt through financial planning and cost efficiency to navigate persistent price pressures.
Conclusion
Inflation from 2020 to 2025 has eroded purchasing power by driving up essential costs, outpacing wages, increasing borrowing expenses, and diminishing savings. While global inflation is easing, Russia and other regions continue to grapple with significant challenges, particularly for low-income groups. Coordinated policies and adaptive strategies are essential to mitigate these impacts and promote economic stability.
