How Currency Fluctuations Impact your Investments?

Currency Fluctuations can affect a portfolio through import costs, export earnings and the value of foreign investments, often without investors noticing it right away. Understanding how currency values are determined helps to explain foreign exchange risk. It also shows why rupee movements can affect even a purely domestic portfolio.

How Currency Valuation is determined?

The rupee’s value against the dollar isn’t fixed by the government on a given day. India follows a managed float exchange-rate system where the rupee’s value is largely determined by market forces and the demand and supply of foreign currency. Exporters, importers, foreign investors and corporations all contribute to these market movements. If one US dollar costs ₹83 today and that rises to ₹86 next month, the rupee has depreciated and the dollar has appreciated, meaning it now takes more rupees to buy the same dollar.

The RBI doesn’t try to fix this rate, but it does intervene when movements turn disorderly. The central bank may buy dollars when the rupee faces sharp appreciation pressure and sell dollars from its reserves when the rupee faces sharp depreciation pressure, often using authorised dealer banks to execute these trades. The RBI may step in to reduce sharp currency movements, but it does not try to keep the rupee at a fixed level. So, some currency fluctuations are normal and will continue to happen.

Currency Appreciation vs Depreciation: What Each Means for Investors

Currency appreciation and depreciation pull a portfolio’s returns in opposite directions depending on where the exposure lies.

Scenario	Effect on foreign investments held by an Indian investor	Effect on Indian exporters	Effect on Indian importers
Rupee depreciates (dollar appreciates)	Value of foreign holdings rises in rupee terms	Export revenue converts to more rupees, generally positive	Import costs rise in rupee terms, generally negative
Rupee appreciates (dollar depreciates)	Value of foreign holdings falls in rupee terms	Export revenue converts to fewer rupees, generally negative	Import costs fall in rupee terms, generally positive

Foreign Exchange Risk in Mutual Funds

Any mutual fund with international holdings may carry currency risk as part of its return, unless the relevant exposure is fully hedged.

If the dollar strengthens against the rupee, a fund holding US stocks sees its value rise in rupee terms even if the US stocks themselves are flat, and the reverse happens if the dollar weakens. This means two investors could pick identical US stocks through two different funds and still see different rupee returns, purely because of when they entered or how the currency moved over their holding period.

Some international funds hedge this foreign exchange market risk explicitly, which reduces the currency’s influence on returns but also removes the potential upside from a weakening rupee. So the decision to hedge or not is itself a meaningful choice for an investor comparing options.

Foreign Exchange Risk in Domestic Stocks

Currency risk doesn’t stay confined to funds with obvious foreign exposure. A domestic company that imports raw materials, components or crude oil pays more in rupee terms when the rupee weakens against the currency it pays in, which directly compresses its profit margins.

The reverse holds for exporters, whose foreign revenue converts into more rupees when the currency weakens, generally supporting earnings and, by extension, the share price. An investor who checks whether a company is a net importer or net exporter before buying its stock is effectively pricing in a risk that often gets overlooked in favour of more visible metrics like revenue growth or margins.

Managing Currency Risk in a Portfolio

A portfolio does not need to avoid foreign investments completely. Investing in both domestic and international assets can help diversify exposure, but it does not guarantee that losses in one area will be offset by gains in another.

For anyone investing directly in foreign funds or stocks, understanding whether the product is hedged or unhedged, and what that choice implies for both downside and upside, matters as much as the underlying asset selection itself. Keeping half an eye on broader currency stability trends, without trying to actively time currency movements, is usually enough for most long-term investors.

Conclusion

Currency fluctuation isn’t a risk that only applies to investors holding foreign assets directly. It reaches into domestic portfolios through importers, exporters and any fund with international exposure. The RBI’s managed float approach allows the rupee to move in response to market forces, while the central bank may intervene to limit excessive volatility, the rupee is not maintained within a guaranteed fixed band. It is better to understand where foreign exchange risk exists in a portfolio and decide whether to hedge it, rather than treat currency movements as a minor concern.

Frequently Asked Questions (FAQs)

Who determines the value of currency in India?

In a managed float regime, market forces play a major role in determining the value of the rupee and the RBI may intervene to limit excessive volatility without targeting a specific exchange-rate level.

How is a country’s currency value determined day to day?

The value of a currency varies with the demand and supply in the foreign exchange market. These movements are affected by the participants in the market such as the exporters, importers, investors and other market players in terms of their currency dealings.

Does currency fluctuations have an impact on investors who merely hold Indian stocks?

Yes, indirectly. The value of the rupee can affect the profits and share prices of the companies that import materials or export goods when their costs and revenues change.

What’s the difference between Currency appreciation and depreciation?

Appreciation means a currency buys more of another currency than before, while depreciation means it buys less. A depreciating rupee benefits exporters and foreign fund holders, while an appreciating rupee benefits importers.

Should I avoid international Mutual Funds because of currency risk?

Not necessarily. Currency risk may either favour or adversely affect returns and some funds may hedge part or all of their foreign-exchange exposure. The appropriate investment should be determined by your own risk tolerance and investment horizon.
