Indexation (Funds)

Published Apr 29, 2024

Definition of Indexation

Indexation in the context of funds refers to the adjustment of the tax thresholds, allowances, benefits, or salaries to reflect the changes in inflation or the cost of living. By doing this, indexation ensures that the purchasing power of income or benefits is maintained over time, despite price increases in the economy. In the financial markets, indexation is also a strategy used by investment funds to align the portfolio’s performance with a specified benchmark index. This is achieved by mirroring the index’s composition, thereby replicating its performance.

Example

Consider a retirement savings account that is adjusted annually for inflation. Suppose in one year, due to a significant rise in the cost of living, the government decides to index the tax brackets and deductions by 2%. This means if the previous tax-free allowance was $10,000, it would be raised to $10,200. Similarly, in the context of investment funds, an index fund designed to track the S&P 500 will adjust its holdings to match any changes in the S&P 500 composition to ensure the fund’s performance closely mirrors the benchmark index’s performance.

For an individual investor, choosing such an index fund means their investment’s performance will closely follow the ups and downs of the S&P 500 index, allowing the benefits of a diversified investment strategy that requires minimal active management, often resulting in lower fees compared to actively managed funds.

Why Indexation Matters

Indexation plays a crucial role in protecting investors and individuals from the eroding effects of inflation. By adjusting income, benefits, and investment strategies for inflation, indexation helps maintain the real value of money over time. For investors, indexation as a strategy simplifies the investment process, allowing them to benefit from the overall growth of the market without needing to make complex investment decisions or frequently adjust their portfolios.

In addition, indexation helps in promoting fairness in taxation. By adjusting tax brackets for inflation, individuals are prevented from being pushed into higher tax brackets simply because of inflationary increases in their income, known as “bracket creep.” This ensures that increases in taxes paid are due to real increases in income rather than nominal increases driven by inflation.

Frequently Asked Questions (FAQ)

How does indexation protect against inflation?

Indexation protects against inflation by adjusting income or benefits to keep pace with the rise in prices, thereby preserving the purchasing power of money. In investments, indexing to a benchmark ensures the investment’s growth potential is aligned with the general market trends, which, over long periods, tend to outpace inflation.

Can indexation apply to all types of funds?

While indexation can broadly apply to many types of investment funds, particularly those that are passively managed, it is most commonly associated with index funds or exchange-traded funds (ETFs) that explicitly aim to track the performance of a benchmark index. Active funds, which aim to outperform the market through selective investment choices, do not follow an indexation strategy in the same way.

What are the drawbacks of indexation in investments?

One potential drawback of indexation in investments is the lack of flexibility to adapt to changing market conditions or to take advantage of specific investment opportunities since the fund’s composition is tied to following an index. Additionally, while index funds often boast lower fees than actively managed funds, they are also subject to market risk and will mirror any declines in the benchmark index.

Indexation serves as a crucial mechanism for adjusting to changes in economic conditions, both in personal finance contexts and in the investment world. By understanding and leveraging the principles of indexation, individuals and investors can make more informed decisions that safeguard the real value of their income and investments over time.
