Inflation and portfolio returns

 

Inflation plays a critical role in shaping portfolio returns, as it erodes the real purchasing power of investment gains. Understanding how to manage its impact is key to building a resilient and growth-oriented portfolio.

📉 What Is Inflation?

Inflation is the general rise in prices of goods and services over time, typically measured by indices like:

• CPI (Consumer Price Index)

• WPI (Wholesale Price Index)

🔹 Example:

If inflation is 6%, then ₹100 today will have the purchasing power of only ₹94 a year later.

📊 Nominal vs. Real Returns

Return Type	Description
Nominal Return	Raw return reported by an investment (before inflation)
Real Return	Return adjusted for inflation (actual gain in purchasing power)

Formula:

$$\text{Real Return} = \frac{1 + \text{Nominal Return}}{1 + \text{Inflation Rate}} - 1$$

🔹 Example:

• Nominal return = 10%

• Inflation = 6%

• Real return ≈ 3.77%

🧩 Impact of Inflation on Asset Classes

Asset Class	Inflation Impact	Notes
Cash / FD	Negative	Fixed interest, no inflation hedge
Bonds	Negative (esp. long-term)	Fixed coupon loses value
Equities	Mixed/Positive (long-term)	Earnings can rise with inflation (selectively)
Gold	Positive	Safe haven, hedge during high inflation
Real Estate	Positive	Property values/rents tend to rise
Commodities	Positive	Prices rise with inflation
REITs/Infra Funds	Mixed	Yield-oriented, inflation-linked leases help

🛡️ Inflation-Hedging Strategies

1. Invest in Real Assets

• Real Estate, Gold, Commodities

• Tangible assets generally retain value over time.

2. Equity Exposure

• Prefer companies with pricing power (FMCG, Utilities, Pharma).

• Look for inflation-linked revenue models (toll roads, energy stocks).

3. Inflation-Protected Securities

• In the US: TIPS (Treasury Inflation-Protected Securities)

• In India: Inflation Indexed Bonds (IIBs) (limited access for retail)

4. Diversified Portfolio Allocation

• Mix of assets reduces inflation shock.

• Dynamic allocation or target-date funds can help.

🧮 Example: Planning with Inflation

Let’s say your retirement goal is ₹1 Cr in today’s value and inflation is 6%. You plan to retire in 20 years.

Future Value needed:

$$\text{FV} = \text{Present Value} \times (1 + \text{Inflation})^{n}$$ $$= 1,00,00,000 \times (1.06)^{20} \approx ₹3.2 Cr$$

→ You must build a portfolio that beats inflation by 4–5% annually over 20 years.
