Indexation is a financial and economic practice designed to adjust various economic variables to account for the effects of inflation. This entry delves into the historical context, categories, key events, formulas, importance, and applications of indexation.
Historical Context
The concept of indexation emerged in response to the challenges posed by inflation. Historically, inflation can erode the value of assets, savings, and earnings, adversely impacting economic stability. To counteract these effects, indexation was introduced in various forms around the world.
In the UK, indexation became integral to the corporation tax system. Indexation allowances, based on the Retail Price Index (RPI), were used to adjust the cost base of assets, mitigating the impact of inflation on capital gains.
Types/Categories of Indexation
- Tax Indexation: Adjusting the cost basis of assets for tax purposes to reflect inflation.
- Wage Indexation: Linking wage increases to the inflation rate to maintain purchasing power.
- Social-Security Indexation: Adjusting social security payments and pensions according to inflation.
- Contractual Indexation: Including indexation clauses in long-term contracts, e.g., lease agreements or annuities.
Key Events
- March 1982: Introduction of indexation allowances in the UK tax system.
- April 1998: Changes in indexation practices with allowances calculated until 5 April 1998 for assets disposed of before April 2008.
- Modern Developments: Various adjustments and policies in line with economic conditions globally.
Detailed Explanations
Tax Indexation in the UK
In the UK, indexation adjusts the cost of an asset to account for inflation over the period of ownership. The formula typically applied:
Where:
- Original Cost: Initial purchase cost of the asset.
- RPI Change: Percentage change in the Retail Price Index during the ownership period.
Wage and Social-Security Indexation
In the context of wages, indexation aims to preserve employees’ purchasing power by aligning wage increases with inflation rates. Social-security indexation adjusts pensions and benefits to ensure recipients maintain their living standards despite rising prices.

Importance and Applicability
Indexation plays a crucial role in mitigating the adverse effects of inflation. It ensures fairness and stability across various economic activities, from taxation and wages to long-term contracts.
Examples
-
Tax Example: A property purchased for £100,000 in 1990 is sold in 2000 for £200,000. If the RPI increased by 50% during this period, the indexed cost would be:
$$ \text{Indexed Cost} = £100,000 \times \left(1 + \frac{50}{100}\right) = £150,000 $$The chargeable gain for tax purposes would then be £200,000 - £150,000 = £50,000. -
Wage Example: An employee earning £30,000 receives an indexed raise in line with a 3% inflation rate. New wage:
$$ £30,000 \times \left(1 + \frac{3}{100}\right) = £30,900 $$
Considerations
While indexation provides protection against inflation, it is not always perfect. Incomplete or inaccurate indexation can leave certain groups, such as lenders or savers, at a disadvantage.

Summary
Indexation is a vital tool in economic management, ensuring that inflation does not unfairly erode asset values, incomes, or benefits. Its application across taxation, wages, and social security helps maintain economic stability and fairness. While not perfect, indexation is crucial for adjusting real values and protecting against the economic ravages of inflation.
