How Money, Inflation & Compounding Work
Before placing a single trade you must understand the forces that drive all markets.
Inflation And Interest Rates
Inflation is the gradual increase in prices over time. When you hear "inflation is at 3%," it means something that cost €100 last year now costs €103. Your money buys less each year unless it grows faster than inflation.
Central banks — the ECB for the Eurozone/Ireland and the RBI for India — control inflation primarily through interest rates. When rates rise, borrowing becomes expensive: mortgages, business loans, and consumer credit all cost more. Spending slows, growth moderates, and inflation cools.
For traders, rate hikes generally pressure stock prices downward (higher discount rates reduce the present value of future earnings). Rate cuts generally push stock prices upward (cheaper borrowing fuels growth and pushes money from low-yield bonds into equities).
The Power Of Compounding
Compounding means your gains generate their own gains. If you earn 10% on €10,000, you have €11,000. Next year, 10% on €11,000 gives €12,100 — that extra €100 is your gains earning gains.
Future Value = Present Value × (1 + r)^n
Worked example:
€10,000 at 10% for 10 years = €10,000 × 1.10^10 = €25,937
€10,000 at 10% for 20 years = €10,000 × 1.10^20 = €67,275
€10,000 at 10% for 30 years = €10,000 × 1.10^30 = €174,494
The Rule of 72: Divide 72 by your return rate to find years to double. At 8%: 72/8 = 9 years. At 12%: 72/12 = 6 years.
Asset Classes
Equities (Stocks): Ownership shares in companies. Historically return 10-12% annually over long periods but with significant short-term volatility.
Bonds (Fixed Income): Loans to governments or corporations paying regular interest (the "coupon"). Lower risk, lower return. Inversely correlated with interest rates.
Commodities: Physical goods — gold, oil, natural gas, wheat, copper. Gold is the classic "safe haven" rising when markets fall or inflation spikes.
Forex: Trading currency pairs like EUR/USD, USD/INR. The largest market at $7.5 trillion daily. Highly leveraged, extremely risky for beginners.
Derivatives: Financial contracts deriving value from an underlying asset. Includes options, futures, and CFDs. Powerful but dangerous without deep education.
Key Takeaways
Monthly SIP Calculation
You start a ₹10,000/month SIP at age 25, earning 12% per year (roughly the Nifty 50's historical CAGR), stopping at 55.
Monthly investment: ₹10,000 Annual return: 12% (monthly: 1%) Duration: 30 years (360 months) Future Value = PMT × [((1+r)^n - 1) / r] = ₹10,000 × [((1.01)^360 - 1) / 0.01] = ₹10,000 × 3,494.96 = ₹3,49,49,600 (≈₹3.5 crore) Your total contribution: ₹36,00,000 (₹36 lakh) Compounding generated: ₹3.14 crore (8.7× your own money)
Insight: If you started at 35 instead (20 years), the result would be about ₹1 crore — less than one-third. Those first 10 years account for the majority of the final value.
