The Indian rupee traces its origins to a silver coin called the rupiya, introduced by Sher Shah Suri, ruler of the Sur Empire, during his reign from 1540 to 1545 CE. The word rupee itself derives from the Sanskrit rupyakam, meaning a silver coin, connected to the ancient term rūpya used in historical texts to describe a stamped piece of metal serving as currency. The rupiya was subsequently adopted across the Mughal Empire and the Maratha era, then taken up by the British East India Company, eventually forming the foundation of modern India’s monetary system.

Long before the rupee existed, the Indian subcontinent had its own rich and varied history of currency. The earliest forms of exchange were not coins but commodities and ornamental objects. The Nishka, for instance, originally referred to a necklace before evolving into a standardized weight of metal used as a medium of exchange, a term that appears in the Rigveda. The first true coins in India, known as punch-marked coins, emerged around the sixth or seventh century BCE. Made from silver and copper and stamped with symbols, they were entirely indigenous in design and based on a weight system using the ratti seed as a standard unit. What followed was a long period in which numerous regional kingdoms and empires produced their own coinage in gold, silver, and copper, creating a complex monetary patchwork across the subcontinent.

The Indian rupee today circulates in both coin and banknote form. Coins are issued in denominations of 50 paise, one rupee, two rupees, and five rupees, though the 50 paise coin has become rare in everyday transactions. Banknotes issued by the Reserve Bank of India come in denominations of ten, twenty, fifty, one hundred, two hundred, and five hundred rupees. The two and five rupee notes have been discontinued in favor of coins. A two-thousand-rupee note was also in circulation but is being gradually withdrawn.

The face appearing on nearly all Indian banknotes today is Mahatma Gandhi, honored as the Father of the Nation. His image was not always on the currency. It first appeared in a commemorative series issued in 1969 for the centenary of his birth and became a permanent fixture on the five-hundred-rupee note in 1987. Since 1996, the Mahatma Gandhi Series has established his portrait as the standard feature of all paper currency. This followed an earlier period in which the first notes of the Republic of India carried the Ashoka Pillar emblem rather than any individual portrait, replacing colonial-era notes that had featured King George VI.

Indian coins take a different approach. Coins currently in circulation do not depict a person but instead display the Lion Capital of Ashoka, the national emblem of India, accompanied by the words Satyameva Jayate, meaning Truth Alone Triumphs. The government also issues special commemorative coins honoring notable historical figures, among them India’s first Prime Minister Jawaharlal Nehru and first woman Prime Minister Indira Gandhi. During the colonial period, coins typically bore the portrait of the reigning British monarch.

Responsibility for issuing Indian currency is divided between two authorities. The Reserve Bank of India holds the exclusive right to issue banknotes under the RBI Act of 1934, while the Government of India, through the Ministry of Finance, oversees the design and minting of all coins. The RBI acts as the government’s agent in distributing coins into circulation. Both forms of currency carry legal tender status, meaning they must be accepted in settlement of debts and are guaranteed by the central government.

The backing behind Indian currency operates differently depending on the form. Coins are issued directly by the government and their value rests on the sovereign guarantee of the state as defined in the Coinage Act of 2011. Banknotes are managed through the RBI’s Issue Department, which is required to hold eligible assets against the currency it puts into circulation. These assets include gold in coin and bullion form, foreign securities, Government of India securities, and rupee coins.

The paper currency is therefore not backed by gold in a fixed one-to-one ratio but rather by the Reserve Bank’s substantial foreign exchange reserves, which serve as a financial buffer. These reserves include foreign currency assets, gold, and Special Drawing Rights. The RBI actively manages this pool, buying and selling foreign exchange in the market to maintain the rupee’s stability against other currencies.

The rupee’s relationship with the US dollar has followed a long-term weakening trend. The exchange rate moved from roughly twenty-three rupees per dollar in 1991 to over ninety-five rupees per dollar by mid-2026. This depreciation means the rupee purchases fewer dollars over time, with recent rates fluctuating around ninety-five to ninety-six rupees per dollar. The rupee’s value is heavily influenced by the strength of the US dollar and US interest rate policy, given how much of international trade and finance is conducted in dollars.

A weaker rupee has direct effects on the domestic Indian economy. The most immediate impact is the rising cost of essential imports, particularly crude oil, electronics, machinery, and fertilizers. Since India imports large volumes of oil, a falling rupee amplifies the import bill and drives up fuel, transportation, and food prices, contributing to inflation and reducing the purchasing power of ordinary citizens. This imported inflation weighs especially heavily on poor households and complicates the Reserve Bank’s monetary policy decisions.

The international picture is more complicated. Conventional economic theory holds that a cheaper currency should boost exports by making Indian goods more competitive abroad, but this benefit is often offset by India’s dependence on imported raw materials and intermediate goods for its manufacturing sector. When the rupee falls, it simultaneously makes exports cheaper and raises the cost of the imported inputs those industries depend on, undermining any competitive advantage. The Export-Import Bank of India has estimated that a large share of India’s exports comes from industries with high import intensity, meaning the net effect of depreciation is often uncertain or negative. Despite a significant decline in the rupee’s value in recent years, merchandise exports have not surged correspondingly, and the trade deficit has widened.

A persistently weak rupee presents a strategic challenge for India’s global ambitions. The depreciation slows the growth of the economy when measured in dollar terms, making targets such as reaching a five trillion dollar GDP harder to achieve. Rapid growth in local currency terms can be substantially undermined by a weak exchange rate when viewed from an international perspective.

The word rupee has been in use for nearly five centuries, rooted in the Sanskrit rupyakam. Formally minted as the rupiya by Sher Shah Suri in the 1540s, it is among the oldest continuously used currency names in the world.

The rupee once served as legal tender beyond India’s borders. Until 1970, the Indian one-rupee note was accepted as official currency in countries including Dubai, Bahrain, Muscat, and Oman. The rupee also functioned as a major trade currency along the eastern coast of Africa and into the Middle East for several decades.

During World War II, Japanese forces printed their own version of the rupee for use in occupied territories including Burma and Indonesia. The strategy was intended to win local acceptance and undermine the British colonial currency system.

Indian banknotes carry micro-lettering so small it is invisible to the naked eye. Each note features the letters RBI and the denomination value engraved around Gandhi’s portrait in text that requires a magnifying glass to read, making it a reliable tool for identifying counterfeits.

Before decimalization in 1957, one rupee was divided into sixteen annas, sixty-four pice, or one hundred and ninety-two pies. Everyday arithmetic under that system was considerably more demanding than the straightforward hundred-paise structure in use today.

The one-rupee note was discontinued in 1994 after the government determined that the cost of printing each note, at one rupee and forty-eight paise, exceeded the note’s own face value. It was reintroduced in 2015 but remains a novelty, with coins far more commonly encountered.

Indian banknotes are not made from wood-pulp paper but from a specialized blend of cotton and cotton rag, which makes them more durable and harder to counterfeit than standard paper. The Reserve Bank is currently piloting polymer notes in ten and twenty-rupee denominations with a view to possible future adoption.
