Inflation & CPI

Inflation is the silent thief that steals your wealth every single day. Understanding it is crucial because even if you're earning 10% on investments, inflation might be eroding 6% of it!

What is Inflation?

Inflation is the rate at which prices of goods and services rise over time. As inflation increases, each rupee buys you LESS.

☕ The Coffee Example

  • 2010: Coffee at CCD = ₹50
  • 2024: Same coffee = ₹150
  • Increase: 200% in 14 years
  • Average inflation: ~8% per year

Your ₹50 from 2010 is worth only ₹17 today in purchasing power!

Why Does Inflation Happen?

1. Demand-Pull Inflation

Too much money chasing too few goods

Example: COVID-19 semiconductor shortage

  • Everyone wanted laptops for work-from-home
  • Chip supply was limited
  • Prices shot up 25-30%

2. Cost-Push Inflation

Production costs increase, businesses pass it to consumers

Example: Petrol price rise

  • Crude oil prices increase globally
  • Transportation costs rise
  • EVERYTHING becomes expensive (vegetables, groceries, delivery)

3. Built-In Inflation

Workers demand higher wages → Companies increase prices → Workers demand more wages...

Example: Minimum wage increases

  • Delivery boy salary ₹15K → ₹20K
  • Swiggy increases delivery fee
  • You pay more for same service

4. Government Money Printing

During COVID, governments printed money to support economy

  • More currency in circulation
  • Same amount of goods
  • Currency value decreases

How is Inflation Measured? (CPI)

CPI = Consumer Price Index

It tracks prices of a "basket" of common goods and services an average person buys.

India's CPI Basket

CategoryWeightage
Food & Beverages45.9%
Housing10.1%
Clothing & Footwear6.5%
Fuel & Light6.8%
Miscellaneous (health, education, transport)28.3%

How it works:

  1. Base year (2012) = 100
  2. Track prices of same items every month
  3. If CPI = 180 today, prices have risen 80% since 2012

Inflation Rate = ((Current CPI - Previous CPI) / Previous CPI) × 100

Real Example

  • Jan 2023: CPI = 165
  • Jan 2024: CPI = 171.6
  • Inflation = ((171.6 - 165) / 165) × 100 = 4% annual inflation

Types of Inflation

1. Creeping Inflation (0-3% per year)

  • Healthy for economy
  • Encourages spending and investment
  • Example: Most developed countries

2. Walking Inflation (3-10% per year)

  • Moderate, manageable
  • India typically in this range (5-7%)

3. Galloping Inflation (10-100% per year)

  • Serious problem
  • Venezuela, Zimbabwe examples
  • Prices double/triple rapidly

4. Hyperinflation (>50% per month!)

  • Economic disaster
  • Currency becomes worthless
  • Zimbabwe 2008: 79.6 billion percent monthly inflation!

Inflation in India (Recent History)

YearInflation Rate
201012% (crisis level)
20155.9%
20206.2% (COVID spike)
20226.7% (due to Ukraine war, oil prices)
20245.1% (controlled)

RBI's target: Keep inflation at 4% (±2%)

How Inflation Destroys Wealth

💸 The Purchasing Power Test

You have ₹1 Lakh saved in a jar (no interest).

At 6% inflation:

  • Today: ₹1L can buy goods worth ₹1L
  • After 5 years: Same ₹1L buys goods worth only ₹74,726
  • After 10 years: Same ₹1L buys goods worth only ₹55,839
  • After 20 years: Same ₹1L buys goods worth only ₹31,180

Your ₹1 lakh lost 69% of its value without you spending a rupee!

The FD Trap

Scenario: You put ₹10 lakhs in FD at 6.5% interest

  • You earn ₹65,000 per year (taxable)
  • After 30% tax: ₹45,500 actual gain
  • Real return: 4.55%
  • Inflation: 6%
  • Net effect: -1.45% (you're LOSING money!)

Lesson: FD is NOT investment for wealth growth. It's for safety, not returns.

Real Rate of Return

Formula: Real Return = Nominal Return - Inflation

Examples:

InvestmentNominal ReturnInflationReal Return
Savings Account3.5%6%-2.5% (Loss!)
FD6.5%6%+0.5% (Barely positive)
Equity Mutual Fund12%6%+6% (Actual wealth growth)
Real Estate8%6%+2% (Modest growth)

Key Insight: Only investments beating inflation create real wealth!

How Inflation Affects Different People

Losers from Inflation

1. Fixed Income Earners

  • Pensioners getting ₹20K/month
  • Amount stays same, but buys less every year

2. Savers (in cash/low-interest accounts)

  • Money loses value sitting idle

3. Lenders

  • You lent ₹1L, get back ₹1L after 5 years
  • But that ₹1L is worth less now!

Winners from Inflation

1. Borrowers

  • Home loan of ₹50L today
  • Repay same ₹50L over 20 years
  • Real burden decreases as currency value falls

2. Asset Owners

  • Real estate, gold, stocks appreciate with inflation

3. Businesses

  • Can increase product prices
  • Wages increase slower than prices (profit!)

How to Beat Inflation

Strategy 1: Invest in Appreciating Assets

✅ Good Inflation Hedges:

  • Stocks/Equity MF: 12-15% long-term (beats inflation)
  • Real Estate: 8-10% (physical asset)
  • Gold: Tracks inflation ~7-8%
  • Commodities: Rise with inflation

❌ Poor Choices:

  • Cash under mattress (-6% real annually!)
  • Low-interest savings (-2% to -3%)
  • Long-term FD in high inflation period

Strategy 2: Increase Income Faster than Inflation

  • Learn high-value skills
  • Switch jobs every 3-4 years (30%+ hikes)
  • Side hustles
  • Business/freelancing (unlimited upside)

Strategy 3: Index Your Expenses

If your salary increases 10% but inflation is 6%:

  • Increase savings by that 4% gap
  • Don't increase lifestyle proportionally

RBI's Role in Controlling Inflation

Tools RBI Uses:

  1. Repo Rate (Currently ~6.5%)

    • Higher rate → Expensive loans → Less spending → Prices cool down
    • Lower rate → Cheap loans → More spending → Inflation rises
  2. Cash Reserve Ratio (CRR)

    • Force banks to keep money with RBI
    • Less money for banks to lend → Controls inflation
  3. Open Market Operations

    • Buying/selling government bonds
    • Controls money supply

Why 4% target?

  • Too low (Less than 2%) = Economic stagnation
  • Too high (>6%) = Erodes savings
  • 4% sweet spot = Growth + Stability

7-Day Action Plan

Day 1: Calculate your real returns (investment returns - inflation)
Day 2: Identify investments earning below inflation (savings account?)
Day 3: Research inflation-beating options (equity MF, index funds)
Day 4: Move idle cash to liquid funds (earns 5-6%)
Day 5: Ensure salary hikes beat inflation (negotiate better!)
Day 6: Track one expense that's inflating fast (education, healthcare)
Day 7: Budget for inflation (add 7% buffer to future expenses)

💡 Final Thought: Inflation is inevitable. The question isn't whether prices will rise—it's whether YOUR income and investments will rise faster. Invest wisely, inflation becomes your ally instead of your enemy!
