Open Bloomberg. Open ET. Open any news app. You will see the same number. ₹97 to the dollar. Historic low. Headlines everywhere.

Here is what nobody is writing about. ₹97 is not where the rupee wants to be. It is where the RBI is holding it.

In the last six weeks, the Reserve Bank of India has burned through somewhere between $12 to $15 billion of its forex reserves. Not on stimulus. Not on growth programs. On one thing. Keeping the rupee from sliding further.

Without that intervention, the rupee's real exit value today is closer to ₹100 to ₹102. We are watching, in real time, one of the most expensive currency defenses in the central bank's history. Almost nobody is connecting the dots to what it means for the average Indian portfolio.

What "Fair Value" Actually Means

Before we get to portfolio implications, let us settle the question that everyone is asking but nobody wants to answer. What is the rupee actually worth right now?

There are three serious ways to answer that.

Purchasing Power Parity (PPP)

The simplest version is the Big Mac Index. A Big Mac in India costs roughly ₹220. The same Big Mac in the US costs roughly $5.79. Pure PPP math says the rupee should trade at ₹38 to the dollar. That number is misleading. It does not adjust for the Balassa-Samuelson effect — poorer economies have systematically lower prices for non-traded services like haircuts and rent. GDP-adjusted PPP puts the fair value closer to ₹65 to ₹70. Either way, the rupee is structurally undervalued in PPP terms. It has been for decades. It will continue to be. This is the long-run view and not a tradeable signal.

Real Effective Exchange Rate (REER)

RBI publishes this monthly. It measures the rupee's value against a basket of trading partner currencies, adjusted for inflation differences. REER of 100 means fair value. Above 100 means overvalued. Below means undervalued. In November 2024, India's REER was 108.14 — the rupee was meaningfully overvalued. By May 2025, REER had moderated to 101.08. At today's ₹97 spot rate, REER has likely fallen to around 92 to 94. The rupee is currently undervalued vs its trading partners by roughly 6 to 8 percent.

Interest Rate Parity (IRP)

The cleanest short-term measure. India's repo rate is 5.25%. US Fed funds rate is around 4.25%. The 100 basis point differential implies the rupee should depreciate about 1% per year against the dollar. From a year ago at roughly ₹85, IRP would have projected ₹86 today. We are at ₹97. The ₹11 gap is the war premium plus capital outflow shock.

Stitch all three together and the picture is sharp. The rupee at ₹97 is below long-run PPP fair value. It is below REER fair value. It is well below where Interest Rate Parity would predict. Without RBI intervention, the market would push it to ₹100 to ₹102.

The RBI is not defending an overvalued rupee. It is defending against fear-driven overshoot. The market wants to price in a worst-case scenario. The RBI is buying time for the worst case not to materialise.

What Is Actually Happening to the Rupee

Three forces are pulling the rupee structurally lower.

Trade deficit shock. With Brent at $111 and the Strait of Hormuz still closed, India's oil import bill has surged. Every barrel costs more dollars. Every dollar requires more rupees.

FII outflows. Foreign institutional investors pulled billions out of Indian equities in March alone. That is foreign currency demand leaving the country. Dollar gets scarcer. Rupee gets cheaper.

Global risk-off flows. The world is in war mode. Money flees emerging markets to US treasuries and gold. India is an emerging market. We are getting fled from.

Against this, the RBI does one thing. It sells dollars in the open market to absorb excess demand. Every dollar sold means fewer reserves. Fewer reserves means less ammunition next time.

This is why the rupee at ₹97 is the rupee on a leash. The market wants ₹102. The RBI is holding ₹97. Eventually, one of them gives.

Why This Matters to Portfolios

Most market commentary is treating this as a temporary squall. Markets are volatile. Hold on. Long term India story is intact. That is not wrong. It is incomplete.

Structural rupee weakness has three real consequences for portfolios.

One. Real returns are lower than nominal returns.

If a portfolio is flat in rupee terms but the rupee has depreciated 10% against the dollar this year, the portfolio is effectively down 10% in dollar terms. Actual purchasing power for anything imported — phones, fuel, foreign education, foreign travel — has shrunk. The investor feels poorer because they are poorer in real terms. A flat portfolio is hiding a real loss.

Two. International exposure becomes structural, not optional.

For years, international funds were treated as a small portion of portfolios. Maybe 5% as a hedge. That math is changing. When the home currency is structurally weakening, international exposure becomes a core position. Not a hedge. Not a diversifier. A core position. 10 to 15 percent international allocation may become the new normal for serious portfolios over the next 12 to 18 months.

Three. Gold is doing what equities were supposed to do.

Gold is up 15% YTD. Silver crossed ₹3 lakh per kilogram. Most retail portfolios never carried significant gold positions. Their owners are now watching neighbours' gold portfolios outperform their carefully constructed equity portfolios. The trust gap this creates is real, and it widens every week the rupee stays under pressure.

What This Means in Practice

Have the rupee conversation proactively. Whether you are an investor or an advisor, do not wait for the question to come up. Send your own one-page note this week explaining what is happening to the currency and what the read is. Whoever explains the macro first owns the conversation.

Audit international exposure. Pull up any portfolio with over ₹50 lakh. Calculate current international fund allocation. If it is under 7%, that is a conversation worth having. Structural rupee weakness will persist 12 to 18 months minimum.

Do not panic-sell anything. This is a positioning moment, not a redemption moment. Indian equity will bounce. But bouncing back to flat is not the same as growing. Use this moment to rebalance, not exit.

The rupee will eventually find its real level. The market always wins that fight in the end. The question is, when it does, which portfolios were positioned for it and which ones were caught explaining what just happened.
