Euro vs rupee — the currency risk hiding inside your Spanish investments

An Indian investor who buys Banco Santander, BBVA or the EWP Spain ETF usually watches one number: the share price, or the IBEX 35. But that is only half the story. Spanish shares are priced in euros, while you invested rupees and will one day spend rupees. Sitting silently between the stock and your bank account is the euro-rupee exchange rate — and over many holding periods it moves your rupee return more than the stock itself does. A Spanish stock can rise in euros while your rupee return shrinks, or barely move in euros while a strengthening euro hands you a gain you did not earn from the company at all.

This guide makes the hidden currency layer visible. It explains how EUR-INR translates into your real return, why the popular trick of buying the dollar-listed ADR adds a currency layer rather than removing one, what the euro has actually done against the rupee lately, and the honest answer on whether a retail Indian investor should bother hedging. The framework is the same one we apply to the dollar in the US-returns guide; only the currency changes.

Your real return has two engines

When you own a Spanish share from India, your rupee return is the product of two things:

1. The euro return on the stock — how much Santander or Iberdrola rose or fell in euros, including dividends.
2. The euro-rupee move — how much the euro strengthened or weakened against the rupee over your holding period.

What happened in euros	What the euro did vs rupee	Your rupee result
Stock up 10%	Euro up 5%	Roughly +15.5% — both engines help
Stock up 10%	Euro down 5%	Roughly +4.5% — currency eats most of it
Stock flat	Euro up 8%	Roughly +8% — pure currency gain
Stock down 5%	Euro down 5%	Roughly -9.75% — both engines hurt

The numbers compound, not add, but the point is plain: the currency is a return engine of its own. For a one-year hold it can dominate; for a ten-year hold the stock usually wins but the currency still nudges the total. Ignoring it means you do not actually understand your own returns.

What the euro has done against the rupee

Over the year to mid-2026, the euro appreciated significantly against the rupee. EUR-INR traded roughly in the 105 to 112 range and rose over the period — a move of well over 10% across the year. For an Indian who held euro assets through that window, the currency was a strong tailwind: even a flat Spanish stock would have produced a healthy rupee gain purely from the euro strengthening.

That is the trap in reading recent history as destiny. A strong run is not a forecast — currencies mean-revert, overshoot and reverse, and the same euro that lifted your rupee returns last year can drag them next year. The honest takeaway is not "the euro goes up" but "the euro adds uncertainty, in both directions." The structural drivers — relative inflation, interest-rate differentials between the eurozone and India, trade balances, capital flows — push the rate around in ways no retail investor can reliably time.

A useful long-run anchor: emerging-market currencies like the rupee tend to depreciate gradually against hard currencies over very long horizons, owing to higher domestic inflation. That historical tendency is a mild tailwind for an Indian holding euro assets over decades, but it is gentle, uneven, and frequently swamped by multi-year swings the other way. Do not bank on it for a five-year plan.

The ADR does not save you — it adds a layer

A common belief is that buying the NYSE ADR of Santander (SAN), BBVA (BBVA) or Telefonica (TEF) in dollars sidesteps the euro problem because you trade in dollars. It does the opposite — it stacks a second currency on top of the first.

Here is why. Santander is a Spanish company; it earns euros and is valued in euros. The dollar-priced ADR is just a dollar wrapper around a euro asset. So your return chain has two currency legs:

1. Euro to dollar — the ADR price tracks the euro share price translated into dollars, so EUR-USD moves are baked into the ADR.
2. Dollar to rupee — then you, in India, convert your dollar proceeds back to rupees, adding the USD-INR move.

Route	Currency legs in your return
Madrid share (EUR)	EUR to INR — one leg
NYSE ADR (USD)	EUR to USD, then USD to INR — two legs
EWP ETF (USD-listed)	EUR to USD inside the fund, then USD to INR — two legs

So the ADR and EWP route actually expose you to both the euro and the dollar against the rupee — more currency moving parts, not fewer. The Madrid line in euros is, paradoxically, the cleaner currency exposure: a single EUR-INR leg. Buying the ADR for liquidity or estate-tax-footnote reasons is fine, but do not buy it imagining it removes euro risk. It does not.

What actually moves the euro against the rupee

You cannot manage what you do not understand, so it is worth knowing the forces that push EUR-INR around — not to forecast it, which no one does reliably, but to recognise why it swings.

• Inflation differentials. India has structurally run higher inflation than the eurozone. All else equal, the higher-inflation currency tends to weaken over time, which is the gentle long-run case for the rupee drifting lower against the euro. But "long-run" can mean a decade, and the path is anything but smooth.
• Interest-rate differentials. When the European Central Bank and the Reserve Bank of India move rates in different directions, capital chases yield, and the rate gap shifts the currency. A widening rate gap in the eurozone's favour can lift the euro; a narrowing one can sink it.
• The dollar's mood. Both the euro and the rupee trade heavily against the dollar, so a strong global dollar phase can pull EUR-INR around even when nothing changed between Europe and India directly. This is why euro-rupee is partly a story about the dollar.
• Trade and capital flows. Eurozone trade balances, Indian current-account dynamics, foreign portfolio flows into Indian markets, and oil prices (India is a big importer) all feed into the rate.

None of these is predictable enough to trade on with a small portfolio. The reason to know them is humility: the euro-rupee rate is the net result of several large, slow, partly-offsetting forces, which is exactly why it wanders and why no recent trend is a promise. Treat any confident EUR-INR forecast — including the implied one in "the euro has been strong, so it will stay strong" — with suspicion.

A multi-year scenario, in rupees

Numbers make the currency engine concrete. Suppose you put 8 lakh rupees into a Spanish holding when EUR-INR was 100, so you bought 8,000 euro of stock. Five years later the stock is up 40% in euros, to 11,200 euro. What you actually get in rupees depends entirely on where EUR-INR landed.

EUR-INR at exit	Euro value	Rupee proceeds	Rupee return
90 (euro weaker)	11,200 euro	~10.08 lakh	+26%
100 (unchanged)	11,200 euro	~11.2 lakh	+40%
112 (euro stronger)	11,200 euro	~12.54 lakh	+57%

Same stock, same 40% euro gain, three very different rupee outcomes — from +26% to +57%. The currency swung your rupee return by more than 30 percentage points without the company doing anything differently. That is the single most important thing to internalise: for a foreign-currency equity, the currency is not a rounding error, it is a co-driver of the result. And note the asymmetry — even a euro that weakened to 90 still left you with a positive rupee return here, because the stock's 40% gain absorbed the currency drag. Over long horizons, a good equity return cushions a lot of currency movement, which is the heart of the case against over-hedging.

How the currency interacts with Indian tax

A point that confuses many investors: India does not tax your currency gain separately. India taxes your capital gain in rupee terms, which means the currency move is already baked into the taxable number.

The mechanics:

• You convert your purchase cost to rupees at the rate when you bought.
• You convert your sale proceeds to rupees at the rate when you sold.
• The difference — which includes both the stock move and the currency move — is your capital gain.

So if the euro strengthened during your hold, your rupee proceeds are larger, your rupee gain is larger, and you pay tax on that larger gain. Under Section 112, a holding over 24 months is long-term at a flat 12.5% with no indexation; 24 months or less is short-term at your slab rate. There is no separate currency tax and no relief for the currency portion — it is all just part of the rupee gain. Our how US stocks are taxed in India guide and the capital-gains calculator apply the same logic to euro assets.

One sharp edge worth noting: a currency tailwind can create a taxable gain even when the stock fell in euros. If Santander dropped 3% in euros but the euro rose 10% against the rupee, you have a rupee gain — and a tax bill — on a stock that actually lost value in its home currency. The reverse can also happen, leaving you with a rupee loss on a euro winner. The currency is doing real work on your tax, not just your return.

Should you hedge the euro-rupee risk?

For most retail Indian investors holding Spanish equities for the long term, the honest answer is no — and here is the reasoning rather than a slogan.

Why hedging usually is not worth it:

• It costs money. A currency hedge has an ongoing cost (the forward points / interest-rate differential), which over years can quietly erode the very returns you are protecting.
• It is hard to do retail. There is no easy, cheap retail product to hedge a small EUR-INR equity exposure from India. The instruments that exist are built for institutions and large amounts.
• Equities dominate over long horizons. For a ten-year-plus hold, the stock's compounding usually outweighs the currency noise, and the currency partly self-corrects over very long periods.
• You diversify currencies anyway. If you hold US, euro and other assets, your currency exposures already spread out, which is a softer, cheaper form of risk management.

When hedging (or being currency-aware) does make sense:

• Short horizons. If you will need the money in rupees within a year or two, a currency swing can wreck the plan — currency-awareness matters more.
• Large amounts. A very large euro position makes the currency swing large in absolute rupee terms, which can justify the cost and effort of a hedge.
• An earmarked rupee liability. If the money is meant for a specific near-term rupee expense, you care about the rupee value on a date, and currency risk is no longer just noise.

If you want to put numbers on it, the currency-hedge calculator lets you model how different EUR-INR paths change your rupee outcome, and the dollar-rupee currency-risk guide walks through the same trade-offs for US assets.

Practical ways to live with the currency, not fight it

You do not have to hedge to be sensible about currency. A few low-effort habits:

• Stagger your remittances. Spreading your LRS conversions across the year rather than lump-summing averages your entry rate, the currency equivalent of rupee-cost-averaging. The LRS and TCS calculator helps plan the timing around the 20% TCS threshold.
• Match horizon to risk. Keep money you will need soon out of single-currency foreign equity; let only long-horizon money ride the currency.
• Read returns in rupees, not euros. Judge your Spanish holdings by their rupee outcome, since that is what you will spend. A euro gain that became a rupee loss is still a loss.
• Know your real currency mix. If you hold EWP or ADRs, remember you carry euro and dollar exposure, not just one — factor that into how diversified you really are.

The bottom line

The euro-rupee rate is not a footnote to your Spanish investments — it is one of the two engines driving your rupee return, and over short horizons it can be the louder one. Recently the euro has been a tailwind, but that is history, not a forecast, and the only safe assumption is two-way uncertainty. Buying the dollar ADR or EWP does not remove euro risk; it adds a dollar layer on top, leaving you exposed to two currencies against the rupee. India taxes the whole rupee gain, currency move included, so the currency reaches all the way into your tax bill.

For long-term holders, the right response is usually not an expensive hedge but a clear-eyed one: invest only long-horizon money, stagger your conversions, judge results in rupees, and know exactly which currencies you are riding. Do that, and the euro becomes a known, accepted part of the trade rather than a surprise. The companion buying, dividend-tax and EWP guides on the Spain hub cover the rest of the picture.
