At the turn of the century, the Indian Rupee was trading at around 45 against the US Dollar. While it held relatively steady through 2010, the subsequent decade saw a steep decline (see the inverse graph above). 

The rupee depreciated to nearly 63 by 2015, crossed 75 in 2020, and just this past week, it briefly breached the 91 mark before settling back just below 90 yesterday.

For an Indian saver, this means your global purchasing power has essentially halved in a generation. This is where the global investing becomes your most powerful tool for wealth protection. 

 

2. Case for Global Investing

In recent years, many money managers in India have been advocating global investing for Indian investors, as part of portfolio diversification, because different assets and markets move at different times. 

They aver that international diversification protects Indian investors from downside, if any from Indian markets, when they diversify their portfolios globally.

This is a sound argument.

Global investing prevents you from "keeping all your eggs in one basket" (home country bias) by spreading risk across markets that don't always move in the same direction (low correlation assets). 

Because international assets often perform well when the Indian market is struggling, this variety helps balance out your losses and keeps your total savings more stable.

It grants access to global innovation leaders and specialised technology sectors that are currently underrepresented or unavailable on Indian stock exchanges. 

Additionally, holding dollar-denominated assets provides a currency hedge, protecting your long-term purchasing power against the gradual depreciation of the Rupee. 

Before we discuss further, let's talk about LRS.

 

3. RBI Liberalised Remittance Scheme

The Liberalised Remittance Scheme (LRS) serves as the legal gateway for Indian investors to invest overseas. The LRS acts as the 'financial passport' that allows you to diversify your wealth into international assets with ease.

India's central bank, Reserve Bank of India (RBI) introduced Liberalised Remittance Scheme (LRS) for resident individuals in Feb2004, so that they could remit up to an amount of USD 25,000 in any calendar year for any permitted current or capital account transactions or a combination of both. 

Initially, the LRS limit was applicable per calendar year. In 2007, this was shifted to financial year.  

The outward remittances limit was enhanced over the years to the current limit of USD 250,000 per financial year. The current limit was set in Jun2015. 

For some reason, the current dispensation in New Delhi has been reluctant to increase the LRS limit in the past 10 years.

RBI LRS Limit: Timeline of Changes > 


 

RBI allows outward remittances for a variety of categories / transactions. They are:

1. Deposit
2. Purchase of immovable property
3. Investment in equity/debt
4. Gift
5. Donations
6. Travels
7. Maintenance of close relatives
8. Medical Treatment
9. Studies Abroad
10. Others*

(* Others include items such as subscription to journals, maintenance of investment abroad, student loan repayments and credit card payments) 

Of these, the three categories (No 1 to 3), namely, deposits, immovable property and investment in equity / debt are considered as capital account transactions because they change your assets abroad (you own them). 

The remaining seven categories (No 4 to 10) are viewed as current account transactions as the monies are for consumption or support (they are spent).   

The next question that comes to mind is: what are the routes available to invest in foreign assets? 

 

4. How to Invest Globally?

Think of the LRS as your financial passport—it gives you the permission to travel; now you just need to decide which investment vehicle will take you to your global destination.

The Four Primary Routes for Global Investing

A.  Direct route: You remit US Dollars from your bank account in India directly to an overseas brokerage account. By using international platforms, you gain personal ownership of global assets, within the overall annual USD 250,000 LRS limit.

With this, you can invest in overseas stocks, ETFs and bonds.

 

B. GIFT City route: Though it's a domestic hub, transfers to GIFT City are legally treated as foreign remittances under LRS.

This allows you to open a foreign currency account in India to trade in global stocks with simplified paperwork while staying within your annual USD 250,000 limit.

 

C. Employee route: If you're an Indian resident receiving employee stock options or ESOPs from a foreign company (employer), you can exercise these ESOPs by sending money abroad. 

Both the cost of acquiring these shares and the value of the shares themselves are counted toward your annual LRS quota.

 

D. Indirect route:  You invest in rupees in India through a mutual fund scheme that holds international assets. 

Because the mutual fund house manages the foreign exchange at an institutional level, these investments are outside the ambit of the RBI's LRS and do not exhaust your personal USD 250,000 limit.

I have refrained from commenting on tax incidence of these various routes for global investing, as I've no expertise on tax matters. However, investors should consult their tax / financial advisors before committing any investments and must focus on after-tax returns on their investments.

5. How Indian Savers are Navigating Global Markets in 2025

A. New Wave of Indian Investors:

Global investing is no longer just for the ultra-wealthy and high net individuals (HNIs). In 2025, nearly half of all new international investors come from Tier 2 and Tier 3 cities like Kochi and Indore. Participation is no longer confined to Bombay or Delhi. 

These savers are starting small—often with less than USD 500—using user-friendly apps (mobile applications) and digital-first platforms to build wealth through fractional shares.

Indian savers are no longer just "testing the waters"; they are strategically building global portfolios.

B. Strategic Use of the "Indirect Route" 

Given the 20 per cent TCS (Tax Collected at Source) on remittances above Rs 10 Lakh transactions, many savvy investors are adopting a hybrid approach. 

They use the Direct Route for specific stock picks where they want personal ownership, while utilising the Indirect Route (Indian mutual funds investing in foreign stocks) for their broader international exposure. 

This allows them to stay globally diversified without exhausting their personal LRS limits or dealing with immediate tax outflows. 

Examples of Indirect Route

As of 30Nov2025, the data given below accessed from Rupee Vest show the assets under management (AUM) of exchange traded funds (ETFs) that focus on US indices. 

Nasdaq 100: Four Indian mutual fund schemes tracking this tech-heavy index (including the Magnificent 7 and other technology stocks) now manage staggering assets of nearly Rs 22,000 crore.

NYSE FANG+: Two Indian mutual fund schemes schemes tracking this index (covering giants like Google, Apple, Broadcom, Crowdstrik and Nvidia) have amassed assets worth close to Rs 6,000 crore.

These two US passive indices are the biggest and are exposed to technology- and communications-heavy sectors in the US. 

There are other funds in India based on foreign indices, but they have small asset size.

As mentioned above, this indirect route does not come under LRS.

 

C. A Focus on Stability and Innovation:

According to media reports, many investors use low-cost passive funds, including ETFs (like those based on S&P 500 or Nasdaq 100) as their foundation, then "add on" global leaders in artificial intelligence (AI), cybersecurity and semiconductors—industries where India’s domestic options are practically nil.

Till now, we discussed about the case for global investing, the contours of LRS, the primary routes of global investing and how investors are using them practically.

So, what do the actual numbers reveal about the global investing routes?

RBI data on outward remittances under LRS for capital account transactions >

The following three categories of LRS can be considered as
   overseas investments (capital account) by Indians
         
Purpose 
1. Deposit 2. Purchase of immovable property 3. Investment in equity/debt Total of the three
                                all data in USD billion
2025-26* 0.3 0.2 1.1 1.7
2024-25 0.7 0.3 1.7 2.7
2023-24    0.9 0.2 1.5 2.7
2022-23    1.0 0.2 1.3 2.5
2021-22    0.8 0.1 0.7 1.7
2020-21    0.7 0.1 0.5 1.2
         
* data from Apr-Sep2025 data: RBI, author
20Dec2025  www.ramakrishnavadlamudi.blogspot.com  

 

If you observe closely, the data reveal a startling paradox. Between financial years 2022-23 and 2024-25, outward remittances for investments (deposits, property and equity / debt) remained stagnant, moving only from USD 2.5 billion to USD 2.7 billion. 

In comparison, the total outward remittances for these years are USD 27.1 bn, USD 31.7 bn and USD 29.6 bn respectively -- showing moderate growth (see chart below for data).  

This means that while we are sending record amounts of money abroad, less than 10 per cent is actually being used to build global wealth. We Indians are happy to spend in dollars, but we are surprisingly hesitant to own assets in dollars. 

Let's look at why this 'spending versus saving' gap is a massive missed opportunity for the Indian saver.

 

6. India is A Nation of Travellers, Not Investors

Where is the money really going? 

Data showing outward remittances under LRS for various categories >

 


Key insights from the above table:

> Total LRS remittances surged from USD 18.8 bn (2019-20) to USD 29.6 bn (2024-25)

> During FY 2025-26 (Apr-Sep2025), the total outflow is USD 14.8 bn 

> Between 2021 and now, almost 90 per cent of LRS outbound money is from four categories, namely, travel, relatives maintenance, gifts and studies abroad (all consumption)

> In the past six years, the share of travel soared from 25 per cent to almost 60 per cent now; indicating preference of resident Indians to travel abroad (Revenge Travel exploded post-Pandemic)

> Indians used to spend USD 5 billion on studies abroad (foreign education of Indian children) five years ago and it has plummeted to USD 2.9 billion during last financial year -- clearly showing Indians find foreign studies less attractive primarily due to anti-immigration policies of the West, including the US 

> One caveat: Numbers alone won't tell you the full story, because the system records flows, not ownership.

 

Overall:

LRS is mostly driven by consumption (travel and education).

Investment abroad is relatively minuscule. 

There is no explosive growth in overseas investments through the LRS route, despite global investing hype.

This is despite:

> Easy access to US stock platforms

> Pitch by money managers in India to invest abroad

> Social media narratives around “global diversification”

Actual data show:

> Overseas investment outflows are flat to mildly rising

> Thee is no structural surge

This reflects: Regulatory friction (Indian regulations are capricious and cavalier), tax complexity and currency risk awareness. 

This reinforces the original thesis that: We Indians have become a nation of global "consumers" rather than global "investors." 

 

7. Some leakages not captured by LRS data

Regulatory scrutiny has recently intensified as the RBI and tax authorities have flagged significant leakages where "Current Account" categories like travel and gifts are being used as proxies for "Capital Account" investments. 

Some high networth individuals (HNIs) have been found using the gift route to remit funds that are subsequently used to purchase foreign securities, effectively bypassing the strict repatriation rules. 
 
Authorities have also detected violations where unspent foreign exchange remitted for travel or gifts is retained in overseas accounts beyond the permitted period and later deployed for asset purchases instead of being brought back to India.

Owing to these practices, headline current account outflows may overstate consumption and partially mask latent demand for overseas asset accumulation.

The bulk of travel and gift remittances may be bona fide, but this shift from pure consumption to hidden wealth-building creates a data mismatch, where the USD 20 billion travel and gift bill likely hides a much larger appetite for global assets. 

By misclassifying these transfers, savers risk severe penalties as the government moves to close these loopholes with tighter bank reporting and the 20% TCS "sting."

This data "leakage" helps explain why the official investment numbers have not shown much growth at USD 2.7 billion in 2024-25 (growth of USD 1.5 billion in five years) while travel and gift spending have grown to nearly USD 20 billion in 2024-25 (a growth of nearly USD 16 billion in the past five years). 

Essentially, while the official data suggests we are only saving 10 per cent of total outward remittances, the reality is that many Indians are likely using the "gift" and "travel" categories as a back door to fund global assets.
 

8. Why no increase in limits for more than a decade? 

If India' foreign exchange reserves are strong and LRS is a “luxury of strength”, why has further liberalisation of LRS limits stalled for a decade?

RBI has been deliberately ignoring industry's demands to increase the USD 7 billion on overseas investments by mutual funds in India. 

The mutual fund industry reached the limit in 2022 and SEBI stopped MFs from making fresh investments abroad.  

Within the industry limit of USD 7 billion, each individual mutual fund house cannot invest more than USD 1 billion.  

It may be recalled the USD 7 billion limit was set in Apr2008 and has not been increased even as India has grown from strength to strength on several fronts (despite several shortcomings in other areas persisting still). 

In addition to the above RBI limit of USD 7 billion, mutual funds in India can invest cumulatively up to USD 1 billion in overseas exchange traded funds (ETFs), as permitted by India's capital market regulator, SEBI or Securities and Exchange Board of India. 

In Mar2024, SEBI directed mutual fund houses to stop accepting fresh subscriptions in schemes that invest in overseas ETFs, effective 01Apr2024. 

To recap: Govt of India and Indian regulators have effectively created four roadblocks for Indian investors:

1. No change in LRS limit for individuals (stagnant at USD 250,000 since 2015)

2. No increase in MF industry limit of USD 7 billion for overseas securities (the limit remains stagnant since 2008; RBI refuses to raise the limit though the industry reached this threshold in 2022)

3. No increase in USD 1 billion ceiling of overseas ETFs; SEBI barred mutual funds from new investments 

4. The 20% TCS rule: If a resident individual sends money abroad, a 20 per cent tax will be collected by the government at source (TCS) if the amount crosses Rs 10 lakh (effective Oct2020, 5% TCS was introduced, which was later raised to 20% in Oct2023).

 

What could be reasons behind creating the roadblocks in the first place? In the absence of any transparency in policy making by the authorities, we can only speculate:

The authorities don't want any capital account convertibility or full current account convertibility?

The authorities don't want to further encourage Indians to invest abroad and want Indian savings to stay within India?

They are cagey about depletion of forex reserves via LRS and overseas securities / ETFs?

Maybe, they are encouraging Indians to invest through GIFT City, by creating these roadblocks? 

They are worried about capital outflows from India, though our forex reserves are roughly USD 690 billion?

There are no definitive answers here.

 

I think the discomfort of authorities (Govt of India, RBI and SEBI) in raising these limits is more to do with a combination of macroeconomics, political economy and crisis memory, not just forex reserves arithmetic.

India's external debt indicators are more than comfortable at this point. But the actions and inaction of the authorities do not reflect the comfortable situation on India's external sector front. 

Roadmap 

India’s position is contradictory:

RBI wants foreigners to hold rupees,
but doesn’t fully trust residents to move capital freely.

They want to internationalise the rupee, but how do authorities build trust and confidence in the Indian trait of capriciousness in policy matters?

That asymmetry is visible in:

> Capped LRS limit for a decade

> Frozen MF overseas limits for more than 17 years

> Ad hoc tightening (TCS, reporting, approvals)

> No published capital account convertibility roadmap

From a global investor’s perspective: “If residents aren’t trusted with their own currency, why should I hold it internationally?

 

9. Action Button: How to Move from Global Consumer to Global Owner

Even with current hurdles and roadblocks, global investing in 2026 remains one of the most effective ways to protect long-term purchasing power for Indian investors, but moving from a global consumer to a global owner requires deliberate strategy.

Holding assets in dollar or euro acts as a vital currency hedge, ensuring that your savings grow in value alongside the rising costs of international travel and foreign education. 

Since these expenses are priced dollars or euros, investing globally prevents your purchasing power from being eroded by the rupee's depreciation. 

By owning dollar or euro assets, you effectively match your future liabilities with your current investments, turning a currency risk into a wealth protection advantage. 

Investors may stay within the Rs 10 lakh annual remittance sweet spot per individual to avoid the 20 per cent TCS drag, use family-level planning where appropriate and rely on GIFT City and IFSC routes when mutual fund overseas caps block access. 

IFSC or International Financial Services Centre (IFSC) is located in GIFT City. IFSC is a conduit to avoid (legally) burdensome capital controls by Govt of India.

Rather than timing currencies, the focus should be on passive, USD-denominated assets that provide both global equity exposure and a natural hedge against rupee depreciation. 

From a policy perspective, raising the long-frozen mutual fund overseas limits would immediately democratise global diversification for ordinary savers. 

Over the medium term, inflation-indexing the LRS limit and simplifying TCS refunds are essential to align India’s outward investment framework with its ambition to create globally invested households.

Finally, you should consult your tax and financial advisors before making any investments, because global investing is a specialised area and there are a lot of grey areas in India's tax and regulation maze.

Tracking the Dollar Index to Understand Dollar–Rupee Moves 18Dec2025

Tracking the Dollar Index to Understand Dollar–Rupee Moves 18Dec2025

Tracking the US Dollar Index is a useful starting point to understand why the rupee moves the way it does, when Indian equity investors are anxious about the rupee sliding beyond 91 to the dollar. Delays around the US–India trade deal, global uncertainty and shifting expectations on US interest rates have added to the anxiety. 

But history shows that sharp rupee weakness is rarely driven by just one factor. Over the past decade, the rupee has moved in cycles shaped by global dollar strength or weakness, foreign investor flows, India's current account deficits and RBI intervention in the foreign exchange market.

Before we deal with the relationship between the movements in dollar index and dollar-rupee exchange rate, let us discuss about the dollar index first. 

 

2. Key drivers of Dollar Index (DXY)

The US Dollar Index (DXY) is a measure of the value of the US dollar relative to a basket of six foreign currencies, namely, the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

Key drivers

Interest rate differentials: When the US Federal Reserve raises interest rates relative to other major central banks, US assets offer higher returns, attracting foreign capital and increasing demand for the dollar and consequently leads to strong DXY.

 ------------------------- 

  

On the other hand, when the US Fed cuts rates relative to other central banks, the dollar can weaken, pushing the DXY lower. Lower US interest rates may also reduce demand for US assets from both domestic and foreign investors. 

This is what unfolded in the first half of 2025, when US stocks and bonds fell, prompting some to theorise that a weaker dollar (falling DXY) was weighing on asset prices, although broader macro factors were also at play.

A falling DXY doesn’t automatically push US asset prices lower; often, both the dollar and asset prices respond to broader macro factors like interest rate expectations, inflation or global risk sentiment. 

In some cases, a weaker dollar can even make US assets cheaper for foreign investors, supporting demand for stocks or bonds. At the same time, domestic factors such as rising rates, earnings concerns or inflation shocks can have a bigger impact on prices than the dollar’s movements.

Economic performance: Strong US economic data such as robust GDP growth, high employment figures (Non-farm Payrolls) and healthy consumer spending boost investor confidence in the dollar compared to other major economies, resulting in a rise in DXY.

Global risk sentiment: The US dollar acts as a safe-haven asset. During periods of geopolitical instability, financial crises or market volatility, investors flock to the dollar for safety, driving the index higher regardless of US economic conditions. This was most evident during the 2008 Global Financial Crisis. 

Relative strength of the Euro: Since the Euro makes up 57.6 per cent of the DXY basket, any significant economic or political shift in the Eurozone (like ECB policy changes or regional instability) has a disproportionately large inverse impact on the dollar index.

Trade balance and demand: A narrowing trade deficit or increased global demand for US exports creates a fundamental need for dollars to settle transactions, which provides structural support for the DXY. 

 

3. What the data are really showing 

The data from 2014 to 2025 show that while USD-INR responds to shifts in global dollar strength, the relationship is strong in some years and partial and muted in other years -- even negative in a few years.

A rising DXY generally pressures the Indian rupee to depreciate, pushing USD-INR exchange rate higher, while a falling DXY supports rupee appreciation. But the relationship is not linear and direct always. 

The above table tracks yearly percentage changes in the US dollar-Indian rupee exchange rate and the US Dollar Index from 2014 to 2025 (partial). Together, these numbers reveal how global dollar cycles interact with the Indian rupee. 

The data help separate periods driven by global dollar strength from those dominated by India-specific forces.

 

4. Understanding the dollar index as the global anchor

 
The US dollar index serves as a global anchor because it acts as a benchmark for measuring the relative strength of the world’s primary reserve currency against other major economies. The dollar index acts as the reference point for global currency movements. 

By consolidating the performance of the dollar into a single number, it allows central banks and international investors to gauge global liquidity and "risk-on" or "risk-off" sentiment at a glance. 

Ultimately, this index acts as a foundation for global finance, influencing the pricing of essential commodities like oil and gold while determining the borrowing costs for nations with dollar-denominated debt.

 
5. The rupee's distinct behaviour

High positive DXY years such as 2014, 2015, 2018, 2021, 2022 and 2024 reflect phases of broad dollar strength, typically driven by US monetary tightening or global risk aversion. Negative DXY years like 2017, 2020 and 2025 indicate phases of dollar weakness or easing financial conditions (see table above). 

USD-INR exchange rate follows the direction of the dollar cycle over long periods but it can be volatile during certain periods, like, the 2013 Taper Tantrum, the 2008 Global Financial Crisis and the Indian government policy logjam in 2011.

However, as part of its managed float exchange rate system (IMF recently described it as crawl-like), Reserve Bank of India, India's central bank, actively intervenes in the forex market to smooth currency movements. 

The degree of RBI's forex intervention is one elephant in the room to accurately predict the relationship between DXY and USD-INR.

Let us unpack the data presented in the above table.

 

(A) Positive correlation

There is a strong correlation, between DXY and USD-INR, in 2022, 2017 and 2015. During these years, the DXY movement exhibited strong influence on USD-INR. For example, in 2015 and 2022, the DXY surged by 9.3 per cent and 8.2 per cent respectively, while the dollar appreciated (versus the rupee) by 4.9 per cent and 11.2 per cent respectively.

During 2017, the DXY declined by 9.8 percent while the dollar too fell by 6 per cent against the rupee. However, these moves have to be seen in the context of other factors; like, FPI outflows from India and any other domestic or global factors.

The year 2022 is a clear example of alignment between global and domestic forces. A strong rise in DXY coincided with a sharp depreciation of the rupee. High commodity prices, capital outflows and aggressive US rate hikes reinforced the global dollar impact on India.

In Mar2022, the US Fed began increasing interest rates due to galloping inflation in the US and India witnessed FPI outflows (equity and debt) of Rs 1.33 lakh crore. 

The India FPI inflows (equity and debt) in 2015 were modest at Rs 0.64 lakh crore.

In 2017, there were strong FPI inflows (equity and debt) amounting to Rs 2.0 lakh crore. 

(B) Negative correlation

Even though USD-INR generally moves in the same direction as the Dollar Index, 2025, 2023 and 2020 break this pattern, with the rupee moving opposite to global dollar trends.

In calendar year 2025 so far, the dollar weakened globally (DXY down 9.3%), but the rupee continued to depreciate (rupee loses 5.1%), pointing to domestic factors such as capital flows, trade dynamics and policy choices overpowering the global dollar trend. 

The US president Trump imposing a 50 per cent tariff on India is a challenging episode for Indian economy in general and the rupee in particular. During 2025 (till yesterday), FPI outflows (equity and debt) are Rs 0.92 lakh crore -- the outflows are weighing on the sentiment. 

In 2020, the dollar weakened sharply, yet the rupee still depreciated modestly, showing negative correlation between DXY and USD-INR,  despite the COVID-19 pandemic-related stress. 

In the year 2020, India witnessed strong FPI inflows (equity and debt) of Rs 1.03 lakh crore, which might have dampened the pandemic-related stress for the rupee.

In 2023, the moves in dollar index and rupee are mild but opposite. India FPI inflows (equity and debt) were strong to the tune of Rs 2.37 lakh crore in 2023. In addition, India experienced strong post-Pandemic economic growth, cushioning the rupee. 

(C) Positive but mild

While DXY and USD-INR had strong correlation in years 2022, 2017 and 2015, some other years witnessed positive but moderate relationship. 

Of the 12 years (2014 to 2025) on which this analysis is based, six years experienced positive but mild correlation. The years are: 2024, 2021, 2019, 2018, 2016 and 2014.

2014: DXY surges by 12.6%, but dollar gains only 2%. FPI inflows (equity and debt) to India were strong at Rs 2.56 lakh crore.

2018: The US Fed increases interest rates; DXY rises 4.1% and USD-INR goes up sharply. India FPI outflows (both equity and debt) were modest at Rs 0.81 lakh crore. 

2024: DXY surges by 7.0%, but dollar gains only 2.9% versus rupee. In 2024, strong India FPI inflows (equity and debt) were strong at Rs 1.66 lakh crore. 

 

Overall, the rupee broadly follows the global dollar cycle: it weakens when the dollar index rises sharply and tends to strengthen during the relatively rare periods when the DXY declines.

In some years, however, the relationship becomes much weaker, as domestic factors begin to dominate currency movements. RBI currency intervention, foreign investor flows and local macroeconomic conditions often dilute the direct impact of dollar on the rupee.

6. DXY, RBI intervention and capital flows

As stated above, rupee movements are shaped by a combination of global and domestic factors. Two of the most important domestic channels are RBI forex intervention and foreign portfolio investor (FPI) flows. 

When the dollar strengthens globally, the RBI typically steps into the market to dampen excessive rupee depreciation by selling dollars from its foreign exchange reserves.
 
Conversely, during periods of dollar weakness, RBI often absorbs inflows by buying dollars, preventing sharp rupee appreciation and building reserves. This asymmetric intervention strategy explains why USD-INR rarely mirrors the magnitude of DXY moves.

FPI flows further shape short- and medium-term rupee dynamics. Equity inflows tend to support the rupee by increasing dollar supply, while equity outflows amplify depreciation pressures during global risk-off phases. 

Debt flows are even more sensitive to interest rate differentials and expectations of US monetary policy. Periods of rising US yields often trigger debt outflows despite a stable or falling DXY, weakening the rupee independently of global dollar trends.  

Instead of allowing sharp appreciation during weak dollar phases or sharp depreciation during strong dollar phases, the RBI-engineered rupee moves gradually. This results in a long-term bias toward mild depreciation while avoiding currency shocks (in fact, 25-year average for dollar-rupee exchange rate movement is 2.7 per cent).
 

7. Summary

While the dollar index doesn't include the Indian rupee, the movements in the index are often a good indicator of the broader trend in the USD-INR exchange rate. A stronger DXY typically leads to a weaker INR against the dollar, while a weaker DXY tends to lead to a stronger INR. 

However, the relationship isn't always linear and neat, as local factors such as India's economic conditions, inflation, current account balance and capital flows can also influence the rupee's value independently of the dollar index.  

The current dollar index is 98.4, while the USD-INR is 90.3. 

For Indian investors, a weakening rupee does not automatically spell trouble, as equity returns are driven more by earnings growth and capital flows than by currency moves alone. 

A depreciating rupee can even support export-oriented companies, while RBI intervention helps limit extreme volatility. 

The bigger risk for investors lies in sudden global shocks that trigger capital outflows, rather than gradual, managed currency depreciation.
