Why NRIs Benefit When the Rupee Falls: Currency Depreciation and Wealth Building Explained

Understanding Currency Depreciation: What Does a Falling Rupee Mean?

Currency depreciation occurs when the value of one currency falls relative to another. For NRIs earning or holding money in US Dollars, a weakening Indian Rupee means that each dollar converts into more rupees than before. This shift can lead to significant gains when converting foreign investments or income back into INR.

For example, if 1 USD was worth ₹85 five years ago and now 1 USD equals ₹90, the rupee has depreciated by approximately 5.88%. This means that simply holding dollars without any investment growth would yield a 5.88% gain in INR terms.

This gain is purely due to currency movement — a factor often overlooked by many investors but critical for NRIs who deal with cross-border finances.

Real-World Scenario: The Power of Currency and Investment Growth Combined

Let’s consider a practical example to understand this better:

• An NRI in the USA invests $50,000 when the exchange rate is 1 USD = ₹85.
• Five years later, the exchange rate moves to 1 USD = ₹90.
• During this period, the investment grows at a modest 5% annual return in USD.

Let’s break down the numbers:

Calculation details:
Investment grows at 5% per year compounded:
Future Value (USD) = 50,000 × (1.05)⁵ ≈ $63,814
Value in INR at old rate (₹85) = 63,814 × 85 = ₹54,24,190
Value in INR at new rate (₹90) = 63,814 × 90 = ₹57,43,260

Notice how the rupee depreciation adds an extra ₹3,19,070 (approximately 5.88%) on top of the investment growth. Combined, this results in a total gain of over 35% in INR terms, even though the investment itself only grew at 5% annually in USD.

Why Currency Movements Matter for NRIs

NRIs often earn, save, or invest in foreign currencies, most commonly the US Dollar. When the rupee weakens, the value of these foreign assets increases in INR terms, boosting the NRI’s net worth back home.

This currency effect can sometimes overshadow the actual investment returns, especially during periods of significant rupee depreciation.

However, it’s important to note that currency fluctuations can work both ways. If the rupee strengthens, the value of foreign investments in INR terms can decline. Hence, NRIs need to consider currency risk as part of their overall investment strategy.

Historical Perspective: Rupee Depreciation Trends and NRI Wealth

The Indian Rupee has experienced various phases of depreciation against the US Dollar over the past decades. For instance, from 2014 to 2024, the rupee weakened from around ₹60 per USD to approximately ₹82-₹83 per USD, a depreciation of nearly 37-38%.

NRIs who held investments in USD or earned in dollars during this period effectively saw their wealth increase substantially when converted back to INR, even before accounting for investment returns.

This trend has been a key factor in the wealth accumulation of many NRIs, especially those who kept a significant portion of their savings abroad.

Investment Growth in Foreign Currency: The Other Half of the Equation

While currency depreciation can boost INR returns, the underlying investment growth in foreign currency is equally important. A stagnant investment with only currency gains is less ideal than one that grows in both currency and value.

Common investment avenues for NRIs in the US and other countries include:

• Equity Mutual Funds and ETFs: Historically, US equity markets have returned around 7-10% annually over the long term.
• Fixed Income Securities: Bonds and fixed deposits in the US typically offer 2-5% returns, depending on the instrument.
• Real Estate: Property investments in the US can appreciate and generate rental income.
• Retirement Accounts: 401(k)s and IRAs offer tax advantages and compound growth.

Even modest returns combined with favorable currency movements can substantially increase wealth in INR terms.

Scenario Analysis: Impact of Different Exchange Rates and Returns

To illustrate the combined impact of currency and investment returns, consider the following scenarios for a $50,000 investment over 5 years:

Risks and Considerations for NRIs

While currency depreciation can be beneficial, NRIs should be aware of several risks:

• Currency Volatility: Exchange rates can fluctuate unpredictably, sometimes eroding gains.
• Tax Implications: Income and capital gains abroad may be subject to taxation in both countries.
• Investment Risks: Foreign investments carry market and credit risks.
• Repatriation Rules: Some countries or banks may have restrictions on moving money across borders.
• Inflation Differences: Inflation in India and the US can affect real returns differently.

A well-diversified portfolio and a clear understanding of currency exposure are essential for managing these risks.

How NRIs Can Strategically Use Currency Movements to Their Advantage

NRIs can adopt several strategies to benefit from currency fluctuations:

• Maintain a Portion of Assets in Foreign Currency: Keeping investments or savings in USD or other strong currencies can hedge against rupee depreciation.
• Invest in Dollar-Denominated Assets: US stocks, bonds, and mutual funds can provide growth and currency appreciation benefits.
• Use Currency Hedging Instruments: Forward contracts, options, or ETFs that hedge currency risk can reduce downside exposure.
• Regularly Monitor Exchange Rates: Timing conversions or remittances during favorable rates can maximize returns.
• Consider Dual Currency Accounts: Some banks offer accounts that allow holding balances in multiple currencies.

Story: How Currency Movement Helped an NRI Family Build Wealth

Meet Raj and Priya, an NRI couple living in New York. In 2015, they transferred $100,000 to invest in a diversified US equity mutual fund. At the time, the exchange rate was ₹65 per USD. Over the next 7 years, their investment grew at an average of 7% annually.

By 2022, the exchange rate had shifted to ₹75 per USD. Let’s see what happened:

• Initial INR value: $100,000 × 65 = ₹65,00,000
• Investment value after 7 years: $100,000 × (1.07)⁷ ≈ $150,000
• INR value at new rate: $150,000 × 75 = ₹1,12,50,000

Raj and Priya’s INR wealth nearly doubled, thanks to the combined effect of investment growth and rupee depreciation. Without the currency move, their INR value would have been $150,000 × 65 = ₹97,50,000 — still a great gain, but ₹15,00,000 less.

This story highlights the power of currency movements in wealth building for NRIs.

Common Misconceptions About Currency Depreciation and NRI Wealth
