How much of your portfolio should be in USD? Currency allocation for Indian investors

The rupee has lost roughly half its value against the dollar in the last 20 years. That structural depreciation is not noise — it's a predictable feature of an economy with higher inflation than the US. For Indian investors building long-term wealth, ignoring USD assets entirely means accepting currency erosion on your entire portfolio.

But how much is the right amount to hold abroad? And should you hedge the currency risk? This guide frames the decision. Use the currency hedge sizing calculator to model your specific situation.

The rupee depreciation baseline

Annualised depreciation: roughly 3.2% per year over 20 years.

What does this mean for returns? A US investor earning 10% annually in a US ETF in USD would, when converted to INR, have earned approximately 13.2% per year — with 3.2% from currency tailwind alone. That's not a guarantee (currency can move against you in any given year), but the structural direction is well-established.

The inflation differential: The rupee depreciates against the dollar because India has higher consumer price inflation than the US — roughly 4–6% vs 2–3% historically. Under purchasing power parity theory, currencies adjust for inflation differentials over time. This is why the depreciation is structural (tied to fundamental macroeconomics) rather than random noise. Until India's inflation consistently matches the US, long-term rupee depreciation against the dollar is the expected baseline.

Why most Indian retail investors should not bother hedging

Currency hedging means using financial instruments (forward contracts, currency futures, options) to lock in a USD/INR exchange rate and eliminate FX uncertainty.

Why it sounds attractive: You own ₹10 crore in US stocks. If INR strengthens from ₹93 to ₹85 per dollar, your USD assets convert to fewer rupees — a loss of ~9% in INR terms even if the stocks rise in USD.

Why it doesn't make sense for most Indian investors:

1. Cost equals expected benefit: Hedging USD/INR costs approximately 3–4% per year (the interest rate differential between India and the US, which sets the forward premium). This cost is almost exactly equal to the expected annual rupee depreciation. Paying 3.5% per year to capture a 3.2% expected currency tailwind = approximately zero net benefit.

2. Accessibility: Currency hedging instruments (USD/INR forwards, futures on NSE/BSE) require a commodity or currency derivatives account. For retail investors, the operational complexity is significant.

3. You're hedging away the benefit: The entire reason to hold USD assets is partially the currency upside. Hedging removes that upside while charging you the cost of the hedge.

4. Time horizon: Over a 10–20 year horizon, the rupee's direction is much more predictable (depreciation) than over 1–2 year periods. Long-term investors can ride out short-term INR strength without hedging.

When hedging makes sense: For institutional investors with large foreign currency liabilities on specific dates (a foreign bond maturing, a foreign acquisition payment), hedging is rational. For an Indian retail investor with a US brokerage account, it generally is not.

The INR depreciation return bonus on USD ETFs

The currency tailwind adds directly to your INR returns from USD investments:

Example: ₹84 invested in VOO in FY 2021-22 (at USD/INR = ₹84, you buy $1 of VOO).

Three years later (FY 2024-25):

• VOO has returned 10%/year compounded → $1 becomes $1.33
• USD/INR is now ₹90

INR return: $1.33 × ₹90 = ₹119.70 INR profit: ₹119.70 − ₹84 = ₹35.70 INR return: 42.5% over 3 years, or ~12.5%/year

Compare to an investment that earned 10%/year purely in INR: ₹84 × (1.10)³ = ₹111.80 → 33% total return, 10%/year

The currency tailwind added approximately 2.5% per year to the INR return.

What happens when INR appreciates: the 2022–2024 experience

INR doesn't only depreciate. There are periods of relative stability or even mild appreciation:

• 2022–2023: INR weakened significantly (₹80 → ₹83) following global dollar strength
• 2023–2024: INR was remarkably stable — held near ₹83–84 for most of the year, with India's strong BoP supporting the currency
• Early 2024: Some INR strengthening as FPI inflows picked up ahead of elections

During periods of INR stability or appreciation, the currency tailwind on USD assets disappears or turns slightly negative. US equity returns are the sole driver of INR returns in such years.

Key takeaway: In any given 1–2 year period, currency can work against you. Over 10+ years, the depreciation trend reasserts itself. Short-term INR strength is noise within a long-term depreciation trend. Don't hedge in response to a 1–2 year stable patch.

UCITS ETFs: EUR/GBP exposure in addition to USD

Indian investors who access US stocks through UCITS ETFs (domiciled in Ireland, listed in London) face a secondary currency consideration: these ETFs may be priced in USD, GBP, or EUR depending on the share class.

CSPX (iShares Core S&P 500 UCITS ETF) listed on the London Stock Exchange:

• Available in USD share class (CSPX): INR/USD movement applies
• Available in GBP share class (CSP1): INR/GBP movement applies
• The underlying assets (S&P 500 stocks) are in USD regardless; the listing currency is just the settlement denomination

Which currency matters: The underlying S&P 500 stocks are all USD-denominated. Whether you buy the GBP or USD share class of CSPX, your economic exposure is to USD (since the portfolio is USD). The GBP pricing of the share adds GBP/USD volatility as a second-order effect — minor for most investors.

Bottom line for Indian investors: When buying UCITS ETFs, buy the USD share class if available — it removes the extra GBP/EUR/USD layer and makes your INR/USD exposure cleaner.

Currency risk in GIFT City investments

GIFT City-route investments (via INDmoney's IFSCA-licensed entity) add an additional currency layer:

1. You invest in INR (to the GIFT City entity)
2. The GIFT City entity converts to USD internally and buys US securities
3. When you sell, the entity converts USD back to INR and credits you

The USD/INR movement still affects your returns — you still get the currency tailwind (or headwind) from INR depreciation. The difference from direct LRS is operational: you don't personally hold a USD account; the currency conversion happens within the GIFT City entity. Currency risk and return dynamics are the same as LRS for the investor.

Match currency to goals

The right framework: hold assets in the currency of your goals.

• Foreign education for a child in 10 years: costs in USD/GBP/AUD — hold a portion in US ETFs or foreign assets to avoid the exchange rate risk
• Early retirement in India: costs in INR — Indian equities, bonds, real estate make sense for most of this
• Potential relocation abroad: costs in USD — US brokerage assets are directly usable
• Travel goals: USD/EUR spend — a smaller USD position makes sense
• Domestic goals only: Indian market exposure is sufficient; USD is upside, not necessity

A sizing framework

There's no universal right answer, but a reasonable starting framework:

5–10% of total portfolio in USD assets for an investor with purely domestic goals and no foreign currency obligations — as a structural hedge against extreme rupee depreciation events.

20–30% for investors with significant foreign currency goals (child's foreign university, likely relocation in 5–10 years). This is the range most financial advisors suggest for a balanced Indian investor.

Up to 30–40% for someone with a US salary history, existing foreign assets, or active LRS deployment who is comfortable with the added FX tracking.

The currency hedge sizing calculator asks for your expected USD-denominated expenses over 10–20 years and computes how much of your current portfolio to allocate to USD assets to cover those obligations without FX risk.

Rebalancing triggers

Setting a USD allocation target requires a rebalancing policy:

Rebalance when: USD allocation drifts more than 5 percentage points from target (e.g., target 25%, rebalance if USD drifts above 30% or below 20%)

Don't rebalance in reaction to: Short-term INR moves or US equity market volatility.

Rebalancing mechanics: If your US allocation grows above target (US market outperformed), you can either sell US assets and redeploy in India (LTCG event if held 24+ months at 12.5%) or simply direct new savings into Indian assets without selling US holdings. The latter avoids the tax event.

The return argument (beyond hedging)

Even without a specific USD-denominated goal, US market returns justify some allocation. The S&P 500 has returned approximately 10–11% in USD annually over the last 30 years. Add 3% rupee depreciation and Indian investors holding VOO over the same period would have seen approximately 13–14% annualised in INR.

Comparison: Nifty 50 has returned approximately 13–14% in INR over the same period.

In pure return terms, the gap is small over long periods. But:

• US exposure diversifies away from Indian political/regulatory risk
• US tech concentration gives access to companies not listed in India (NVIDIA, Apple, Meta, Amazon)
• USD assets act as insurance against tail risk (India-specific shocks, currency crises)

The LRS constraint

The $250,000/year LRS cap per person limits how fast you can build a USD position from scratch. At current rates (≈$250,000 = ₹2.3 crore/year), most retail investors won't hit this ceiling. But for HNIs trying to shift a significant portfolio offshore quickly, the cap is real.

TCS: Above ₹10 lakh in LRS remittances per year, 20% TCS is deducted at the bank. This is a creditable prepayment — you recover it in your ITR — but it creates cash drag. The LRS & TCS calculator shows the exact cash drag per remittance.

Practical implementation

For most investors, the simplest USD position is a broad US market ETF:

• VTI (Vanguard Total Market, 0.03% expense ratio): entire US market
• VOO (Vanguard S&P 500, 0.03%): S&P 500 only
• CSPX (iShares S&P 500 UCITS, 0.07%): UCITS equivalent, estate-tax safe for NRAs

Accessible via Vested, INDmoney, Interactive Brokers, or similar platforms after LRS remittance from your bank.

The one-line version

3% annual rupee depreciation is structural — a 20–30% USD allocation makes sense for most Indian investors, larger if you have dollar-denominated goals. Don't hedge it (cost equals the expected benefit). Use the currency hedge sizing calculator to match your foreign asset position to your actual USD obligations.
