NRI Real Returns and Rupee Depreciation: Why Your 8% Indian FD Lands as 5% in Dollars Once the Currency Drag Is Counted

Your bank app shows an NRE fixed deposit ticking along at 8%, and a friend in Dubai mentions his dollar account pays 4%. You feel comfortably ahead, double the rate, same money. Then you remember you will eventually spend this in dollars, and you do the conversion: the rupee was 95 to the dollar when you opened the deposit, and it is drifting toward 100. Run the arithmetic and your 8% in rupees is landing closer to 5% in dollars. The deposit did exactly what it promised. The rupee quietly took the other three points. This is currency drag, and it sits on every rupee asset an NRI owns whether or not anyone tells you about it.

The 30-second answer: An NRI's real return is the return in the currency they actually spend, not the rupee return on the statement. A rupee asset's home-currency return is the rupee return reduced by however far the rupee falls over the holding period, computed by dividing (1 plus the rupee return) by (1 plus the rupee depreciation), not by subtracting. The rupee has depreciated against the US dollar by roughly 3% to 5% a year over long periods, around 3.4% a year over the last decade, reflecting India's higher inflation. So a 7% NRE FD with a 3% rupee fall returns about 3.9% in dollars, and 12% Indian equity lands near 8.7%. Never compare an 8% rupee FD with a 4% dollar deposit as equals: the extra yield is the market pre-paying you for the depreciation it expects. The practical fix is matching assets to the currency of your future goal, and using FCNR deposits (held in foreign currency, no rupee risk) where you want home-currency certainty.

This guide is about the single number most NRIs measure wrong: their return. You earn in dollars, pounds, dirhams or Canadian dollars, you will spend in one of those, and yet every Indian statement, fund factsheet and bank app you read reports your performance in rupees. The gap between those two numbers is currency drag, and over a long accumulation it is the difference between two very different retirement figures. I will set out why the rupee return flatters every India investment you make, show the correct way to convert a rupee return into your spending currency, work the arithmetic on a five-year deposit in full, and then deal with the edge cases that trip people up: the dirham peg, the real cost of hedging, and the one rule that resolves all of it, matching the currency of the asset to the currency of the goal. If you want the deposit-level decision first, NRE FD vs FCNR FD is the natural companion, and the dedicated currency hedging guide goes deeper on whether to formally hedge at all.

The return on your statement is not the return you earn

Start with the uncomfortable fact. If you hold an NRE deposit, Indian mutual funds, direct Indian equity or a flat in Pune, every figure you see is denominated in rupees, but your life is priced in something else. Your rent in London, your mortgage in Toronto, your school fees in Dubai, your eventual cost of living wherever you settle, all of it is in your home currency. The two are joined by an exchange rate that does not sit still, and its long-run direction is against the rupee.

The reason the drag stays invisible is structural. A fund that returned 12% in rupees prints "12%" on the factsheet. It does not print the under-9% you actually earned in dollars after the rupee fell that year, because the fund has no idea what currency you spend in. The rupee return is the gross figure. The home-currency return is your net. The difference between them is the currency drag, and because nobody reports it for you, most NRIs never subtract it. Over a single year it is a minor irritation. Compounded across a fifteen-year accumulation toward retirement, it is large enough to change the plan.

There is one hinge that decides whether the drag matters at all, and I will keep returning to it: currency drag only bites on money you will actually convert. If you will spend the money in India, as rupees, there is no conversion and no drag to worry about. The rupee falling against the dollar does not make your Indian flat or your child's Indian college fees cost more in rupees. So the question is never simply "is the rupee falling", it is "will I convert this back to my home currency, and if so, when". Hold that thought, because it is what separates the assets you should worry about from the ones you should not.

The long-run rupee trend, with the numbers attached

You cannot reason about currency drag without an honest anchor for how fast the rupee moves, so here is the data rather than the sentiment.

Over long horizons the rupee has depreciated against the US dollar at roughly 3% to 5% a year. Measured from mid-2026, the rupee fell about 3.9% a year over the last five years, 3.4% over ten years, 4.3% over fifteen years, and 3.5% over twenty years. Stretch the lens back to liberalisation in 1991, when the rate was around Rs 17 to the dollar, and the rupee crossed 95 to the dollar in 2026, an average annual depreciation of roughly 4% to 4.5% across those three-plus decades. The rupee touched an all-time low near 95.2 in early May 2026 and has hovered around the mid-95s since.

The recent stretch has been steeper than the smoothed average, which matters for anyone with a near-term conversion date. The rupee was among Asia's weakest currencies in 2025, falling close to 4.9% that year, and it weakened a further 7% or so in the first five months of 2026 alone, the sharpest pace in several years, with the Rs 100 mark within reach if the run continues. None of that is a forecast. It is the recent path, and the recent path has been jagged and downward.

Why does the long-run trend persist so reliably? The textbook driver is the inflation differential. India has run higher inflation than the US, the UK or the eurozone for decades, and a higher-inflation currency loses purchasing power faster, with the exchange rate adjusting over time to reflect the gap. This is not a temporary policy stumble. It is a structural feature of an emerging-market currency measured against developed-market ones. So the base case any NRI should plan around is continued rupee depreciation over a long horizon, not because anyone is calling a crisis, but because the inflation gap that has driven the slide for thirty years has not closed.

A word of honesty here, because it is load-bearing. Nobody knows where the rupee will be in five years. The 3% to 5% range is a long-run average drawn through a path that has, in individual years, been flat, sharply down, and occasionally up. I am not forecasting a particular level. What I am saying is narrower and better supported: over a long holding period, the reasonable planning assumption is that the rupee depreciates rather than appreciates against developed-market currencies, because the structural inflation gap points that way. If you genuinely believed the rupee would strengthen, the entire logic of this guide would flip, and you would tilt hard into rupee assets. The case for taking currency drag seriously rests on depreciation being the base case, which the long-run data supports without needing any single forecast to be right.

How to convert a rupee return into your home-currency return

Most NRIs do this conversion wrong in a way that happens to be forgivable at low numbers and misleading at high ones. They subtract. They take a 12% rupee return, knock off 3% for the rupee, and call it 9%. That is close, but it is not the arithmetic.

The correct method is to divide, not subtract. Your home-currency return is:

(1 + rupee return) / (1 + rupee depreciation) − 1

Take the 12% equity example with a 3% rupee fall. The calculation is 1.12 divided by 1.03, minus 1, which is 8.74%, not the 9% you get by subtracting. The two are close at these rates, but the gap widens as returns rise, and it widens further once you compound across several years. For a 7% NRE deposit with the same 3% rupee fall, the sum is 1.07 divided by 1.03, minus 1, which is about 3.88%, call it 3.9%. So the rough rule, "knock the depreciation rate off the rupee return", is a fine sanity check, but the divide-and-compound method is the one to trust when the number actually drives a decision.

Lay out a few cases side by side, using a 3% annual rupee fall against the dollar, which sits in the middle of the long-run range.

Asset	Rupee return	Rupee fall	Home-currency return
NRE fixed deposit	7.0%	3.0%	about 3.9%
Debt fund / bond	8.0%	3.0%	about 4.9%
Indian equity (long run)	12.0%	3.0%	about 8.7%
Aggressive equity year	18.0%	3.0%	about 14.6%

Two things fall out of that table. First, the drag is roughly constant in percentage-point terms across assets, close to the depreciation rate, which is why a fixed deposit suffers proportionally more: losing three points off seven hurts more than losing three points off twelve. Second, and this is the one that should change behaviour, the lower-yielding the rupee asset, the more of its return the currency eats. A 7% NRE FD handing back under 4% in dollars is handing back roughly half its headline. That is the precise reason an NRI should never line up an 8% rupee deposit against a 4% dollar deposit and conclude the rupee one wins by four points. After depreciation, the gap is a fraction of that, and the rupee deposit carries a risk the dollar deposit does not.

Worked example: Rs 10,00,000 at 8% over five years

Abstractions do not finish the job, so here is the full arithmetic on a concrete deposit. You invest Rs 10,00,000 in a rupee NRE fixed deposit at 8% for five years, compounding annually. The rupee is at 95 to the dollar on the day you fund it.

First, the rupee outcome, which is the easy and flattering part. At 8% compounded for five years, the growth factor is 1.08 to the fifth power, which is about 1.4693. So:

• Rs 10,00,000 × 1.4693 = about Rs 14,69,000 at maturity in rupees.

That is the number your bank app will show, and on its own it looks like a clean 8% a year. Now convert both ends into dollars.

At the start, Rs 10,00,000 at 95 per dollar is:

• Rs 10,00,000 / 95 = about USD 10,526 invested.

The naive expectation, the one most people carry without checking, is that 8% in rupees is roughly 8% in dollars, so the corpus should be worth about USD 10,526 × 1.4693, which is about USD 15,466 at maturity. Hold that figure. It is the dollar outcome you would get only if the rupee stayed at 95 for all five years.

Now bring in the depreciation. Suppose the rupee drifts from 95 to about 110 per dollar over those five years. That is a fall of about 3% a year (110 divided by 95 is about 1.158, and 1.158 to the power of one-fifth is about 1.0297, so close to 3% annualised). At maturity you convert the rupee corpus at 110:

• Rs 14,69,000 / 110 = about USD 13,355 received.

So the honest comparison is USD 10,526 in, USD 13,355 out, over five years. The total dollar gain is about 26.9%, and the annualised dollar return is:

• (13,355 / 10,526) to the power of one-fifth, minus 1 = about 4.9% a year.

Set the three numbers next to each other and the drag is unmistakable:

Measure	Value
Rupee corpus at maturity	about Rs 14,69,000
Headline rupee return	8.0% a year
Naive dollar corpus (rupee flat at 95)	about USD 15,466
Actual dollar corpus (rupee at 110)	about USD 13,355
Real dollar return	about 4.9% a year

The deposit earned its 8% in rupees in full. The fund manager, in this case the bank, did the job. But the rupee's slide from 95 to 110 converted that 8% rupee return into a 4.9% dollar return, and shaved more than USD 2,100 off the maturity value you would have naively expected. Nothing went wrong. The currency simply did what the long-run trend says it tends to do. Run the same exercise on a 12% equity return over the same five years and the same currency path: Rs 10,00,000 grows to about Rs 17,62,000 in rupees, converts at 110 to about USD 16,018, and lands as a dollar return of roughly 8.8% a year, against the 12% on the factsheet. The pattern holds whatever the asset. The rupee takes its cut at the door.

One caveat I owe you for honesty: I have used 110 as an illustration of a roughly 3% annual path, not as a prediction. The rupee could sit at 105 in five years, or past 115, or somewhere unexpected. The point of the example is the method and the direction, not the specific level. Plug in your own depreciation assumption and the arithmetic still tells you the same thing: measure the return where you spend it.

Why the extra rupee yield is not free money

It is worth understanding why rupee assets pay more in the first place, because once you see it, the temptation to chase the higher headline rate fades.

Rupee deposits and rupee bonds pay more than dollar or pound deposits of the same maturity. A rupee NRE FD pays around 6.5% to 7.25% as of June 2026; a USD FCNR deposit pays around 3.35% to 5.45%; Indian government bonds out-yield US Treasuries. That gap, the interest-rate differential, is not a gift. If the rupee paid 7%, the dollar paid 4%, and the exchange rate never moved, every investor with access would borrow dollars and pile into rupee assets, and that flood would push the rupee up until the gap closed. The gap survives precisely because the market expects the rupee to fall by roughly the differential, cancelling the extra yield over time.

Put plainly: the higher rupee yield is the market paying you, in advance, for the depreciation it expects. This is why comparing an 8% rupee deposit with a 4% dollar deposit as if they were equivalent is a category error. They are not the same product in different wrappers. One carries rupee risk and pays you a premium for bearing it; the other carries no rupee risk and pays less. The fair comparison is the rupee return after expected depreciation against the dollar return, and on that basis the four-point headline gap usually shrinks to a point or two, sometimes less. The deeper version of this argument, including covered interest parity and what a forward actually costs, lives in the currency hedging guide, but the takeaway here is enough on its own: extra rupee yield is compensation for risk, not a free lunch.

Edge cases

The general rule, measure your return where you spend it, has several wrinkles that decide what you actually do about it.

The dirham is pegged to the dollar, so Gulf NRIs face the dollar effect

If you live in the UAE and think in dirhams, you might assume currency drag does not apply to you because the dirham feels stable. It is stable, but only because it is pegged to the US dollar at a fixed rate. That peg means a dirham-spending NRI experiences exactly the same rupee drag as a dollar-spending one: when the rupee falls against the dollar, it falls against the dirham by the same amount. The same logic carries to the Saudi riyal and the other Gulf currencies tied to the dollar. So a Dubai-based NRI converting an 8% rupee FD back into dirhams faces the same arithmetic as the worked example above, near 5% after a 3% fall, not 8%. The peg removes dirham-versus-dollar risk for you, but it does nothing about rupee-versus-dollar risk, and that is the one eating your India returns. Do not let the stability of the dirham lull you into measuring your India performance in rupees.

Hedging exists, but it is rarely worth the cost for retail NRIs

The obvious instinct is to hedge the currency away with a forward or a futures contract. You can, but the cost is not incidental. Under covered interest parity, the price of hedging the rupee, the forward premium, equals the rupee-dollar interest-rate differential, roughly 3% to 6% a year in mid-2026. That is, by construction, approximately the market's own forecast of how far the rupee will fall. So hedging does not let you keep the high rupee yield and dodge the depreciation. It swaps an uncertain depreciation for a near-certain hedging fee of similar size, plus the dealer's spread. That can be the right trade when you have a fixed near-term liability you cannot move, and a bad currency year would genuinely hurt. For a long-horizon NRI building a corpus, paying 3% to 6% a year to remove a risk that historically costs about the same is usually a poor deal. The honest read is that formal hedging is a tool for a defined short-term liability, not a default for the whole portfolio.

The clean answer for most people: match assets to the currency of the liability

Here is the rule that dissolves most of the problem without any derivative. Match the currency of the asset to the currency of the goal it funds. Currency drag only exists when you convert, so the trick is to arrange your money so you convert as little as possible.

• For rupee goals, retiring in India, an Indian property, a child studying in India, family support in India, hold rupee assets. There is no conversion, so there is no drag. NRE deposits, Indian mutual funds and Indian equity are entirely appropriate here, and the rupee return on the statement is, for this purpose, the return that matters. Measuring it in dollars would be the mistake.
• For foreign-currency goals, a house in your country of residence, your children's education abroad, your own retirement abroad, hold foreign-currency assets, or hold rupee money inside an FCNR deposit, which sits in the Indian banking system but is denominated and repaid in your foreign currency, so the rupee never touches it. That removes rupee risk structurally, and you pay for it through a lower yield rather than a dealer's fee.

Most NRIs hold a mix of rupee and foreign goals, so the practical exercise is to split the portfolio by the currency of the goal, not by which country pays the higher rate. The mechanics of building the rupee side are in building an India corpus, the asset-allocation frame is in NRI portfolio asset allocation, and the two-country retirement split is in retirement planning across two countries.

Rupee goals are a feature, not a loophole

It is worth being precise about why a rupee goal escapes the drag, because it is easy to mistake it for accounting sleight of hand. It is not. If you will genuinely spend the money as rupees in India, then the dollar value of that money is irrelevant to you, the same way the yen value of a British pensioner's pension is irrelevant if they never visit Japan. The drag is real only against the currency you actually spend. The danger is the reverse mistake: telling yourself a pot is a "rupee goal" to justify holding rupee assets, when in truth you expect to convert it back home. If there is any real chance you will repatriate the money, treat it as a foreign-currency goal and price the drag in. Honesty with yourself about where the money is going is the whole game.

Spreading conversions over time blunts the timing risk

Even for money you will convert, you are not forced to do it all on one unlucky day. If you remit or repatriate in regular tranches rather than one lump, you average across exchange rates and avoid betting the whole outcome on a single rate. This does not remove the long-run drag, the trend still runs against you, but it removes the additional risk of converting everything at the worst possible moment. The mechanics of doing this deliberately are in dollar-cost averaging currency for NRIs.

The closing read

The honest read is that the rupee return on your statement is the gross figure, and the only return that matters to an NRI is the net one, measured in the currency you spend. The gap between the two is currency drag, and over a long accumulation it is large enough to change which assets you should hold and how you should compare them. An 8% NRE deposit is not twice as good as a 4% dollar deposit, because once you reduce the 8% by the rupee's expected fall, the two land within a point or two, and only one of them carries rupee risk. The extra rupee yield is the market pre-paying you for depreciation it already expects, not a free lunch.

What follows from that is not "avoid rupee assets". It is "know which currency each pot is for". Hold rupee assets for rupee goals and stop measuring them in dollars, because for money you will spend in India the drag is imaginary. Hold foreign-currency assets, or FCNR deposits, for foreign goals, because for money you will bring home the drag is real and recurring. Reserve formal hedging for a fixed near-term liability you cannot move, since for everyone else it costs roughly what it saves. And be honest with yourself about where each rupee is ultimately going, because that single judgement, not the headline interest rate, decides whether the currency is your problem or someone else's. I will not pretend to know where the rupee sits in five years. I will say the planning assumption that has held for thirty years, gentle depreciation against developed-market currencies, is the one to build around, and measuring your real return is how you stop the rupee surprising you at the door.
