Not as a trading idea, but as a way to improve how portfolios behave over time.
At its core, the argument is: while asset allocation reduces market risk, currency diversification can help reduce “life goal risk”, the gap between where money is earned and where it is eventually spent.
Helping investors protect future purchasing power
A key benefit highlighted by experts is the protection of long-term purchasing power, especially for global goals.
Anindya Banerjee, Head of Commodity and Currency Research at Kotak Securities, a full-service stock brokerage firm, notes that most Indian portfolios are effectively “single-currency portfolios,” even when diversified across asset classes.
Salaries, savings and investments are all rupee-linked, which can quietly create risk when future expenses are not.
Vivek Singhal, Founder and CEO of Strategic Business Management Co, a consulting firm, also notes that while portfolios may appear diversified across asset classes, exposure remains largely rupee-centric. For investors with global goals, this creates a timing and purchasing power mismatch, where future needs may rise faster than domestic savings trajectories.
This becomes particularly relevant for goals such as overseas education, migration or international travel, where costs are denominated in dollars or other foreign currencies. Even if investments grow steadily in rupees, a weaker domestic currency can make those goals more expensive in real terms.
Currency diversification helps reduce that uncertainty by aligning part of the portfolio with the currency in which future spending may occur.
Improving portfolio resilience across cycles
Another way currency exposure can help investors is by reducing dependence on a single economic cycle.
Tajinder Virk, Co-Founder & CEO of Finvasia Group, a multinational financial technology firm, points out that global markets do not move in sync. Different economies lead at different points in time, and global exposure allows investors to participate in multiple growth cycles rather than relying solely on domestic conditions.
This cross-market exposure can improve resilience, especially during periods when Indian equities underperform global markets or vice versa.
Shruti Jain, Chief Strategy Officer, Arihant Capital Markets, an Indian financial services firm and SEBI-registered stockbroker, adds that even a modest allocation to global assets, around 10–15%, can help smooth overall portfolio volatility by introducing assets that respond differently to global economic conditions.
Reducing “hidden concentration risk”
While investors often think they are diversified because they hold multiple asset classes, several experts argue that this overlooks a deeper layer of concentration: currency.
Banerjee explains that equities, debt instruments and even real estate in India are all ultimately priced in rupees. This creates a structural concentration that is easy to miss in traditional portfolio construction.
Currency diversification helps reduce this hidden dependence on a single monetary system, making portfolios less sensitive to domestic macroeconomic factors alone.
Aligning investments with real-life goals
Perhaps the most practical benefit of currency diversification is its role in goal alignment.
Paresh Bhagat, Chairman, Mangal Keshav Financial Services, a stockbroking firm, highlights the mismatch that occurs when future expenses are in foreign currencies but savings are entirely rupee-based. In such cases, even well-performing domestic investments can fall short if exchange rates move unfavourably.
Currency exposure helps bridge this gap by ensuring that at least part of the portfolio naturally adjusts with global currency movements, making long-term planning more predictable.
Building global exposure into mainstream portfolios
Gurmeet Singh Chawla, Managing Director of Master Portfolio Services, a SEBI-registered Portfolio Management Service (PMS) in India, sees currency diversification as relevant in a volatile global environment shaped by shifting trade flows and geopolitical uncertainty.
He notes that even a 10–15% allocation to global assets can offer meaningful diversification benefits. Importantly, he adds that access is no longer limited to large investors, with international mutual funds and fund-of-funds making global exposure more accessible to retail participants.
A stabilising role, not a return driver
However, it must be noted that currency diversification is not about generating higher returns.
Instead, it works more as a stabiliser.
Sitashwa Srivastava, Founder & CEO of Borderless, a cross-border fintech infrastructure and digital banking company, describes it as a way to reduce uncertainty rather than enhance gains. Currency movements can go both ways, and expecting consistent gains from rupee depreciation is a flawed assumption.
What investors can realistically expect is smoother outcomes over time, less distortion in long-term goals caused by exchange rate fluctuations.
A contrasting view: Questioning currency as an investment layer
Not all experts view currency exposure as a necessary portfolio component.
Sidharth Sogani Jain, Founder, CEO & Fund Manager at Blue Aster Capital and CREBACO Global, argues that currencies do not have intrinsic fundamentals like productive assets. In his view, relying on currency exposure for diversification introduces speculation rather than risk reduction.
He suggests that investors may achieve better hedging through real assets such as gold, silver, copper and land, which are backed by tangible supply-demand dynamics.
Helping investors avoid behavioural bias
Another subtle benefit is behavioural. Investors often overweight domestic markets due to familiarity, a tendency known as home bias.
By introducing global currency exposure, investors are naturally nudged into a more balanced allocation across geographies. This reduces overdependence on domestic sentiment cycles and encourages a more disciplined, long-term approach to wealth creation.
