Muhammad bin Tughlaq’s experiment of introducing token currency could not succeed on account of

1. The Tughlaq Dynasty: Administrative Vision (basic)

Hello! Welcome to our first step in understanding the Medieval Indian economy. To understand how the economy functioned, we must look at the administrative visions of the rulers who shaped it. One of the most fascinating figures in this regard is Muhammad bin Tughlaq (r. 1324–1351), a ruler often described as an "innovator" ahead of his time History, class XI (Tamilnadu state board 2024 ed.), Advent of Arabs and Turks, p.144.

In 1329–1330 CE, Muhammad bin Tughlaq introduced a revolutionary experiment: Token Currency. In the medieval world, coins usually had "intrinsic value" (a gold coin was worth the actual weight of the gold). Tughlaq, however, introduced copper and brass coins and decreed that they should be accepted at the same legal value as the silver tanka. This concept is the ancestor of our modern paper currency, where a piece of paper is valuable only because the government says it is.

While the vision was modern, the execution faced a critical flaw: the lack of a state monopoly over minting. Because the design of these new coins was relatively simple and lacked complex security features, it became incredibly easy to forge. The contemporary historian Ziauddin Barani famously noted that "the house of every Hindu [and citizen] was turned into a mint" History, class XI (Tamilnadu state board 2024 ed.), Advent of Arabs and Turks, p.145. The market was soon flooded with counterfeit coins, leading to a massive devaluation of currency and a complete breakdown in trade as merchants refused to accept the "worthless" copper.

Ultimately, the Sultan had to withdraw the experiment. In an act of administrative integrity that further depleted the state's wealth, he allowed people to exchange their copper tokens—even the forged ones—for genuine gold and silver coins from the royal treasury History, class XI (Tamilnadu state board 2024 ed.), Advent of Arabs and Turks, p.145. This drained the treasury but remains a classic example of a brilliant economic idea failing due to poor technical implementation.

Feature	Traditional Coins	Tughlaq’s Token Currency
Material	Gold or Silver	Copper or Brass
Value Source	Intrinsic (the metal itself)	Representative (State Decree)
Outcome	Stable but expensive to produce	Economic chaos due to forgery

2. Evolution of Sultanate Coinage: Tanka and Jital (basic)

To understand the medieval Indian economy, we must first look at how the Delhi Sultanate revolutionized the way people traded and paid taxes. Before this period, India had a fragmented system of regional coins. It was Sultan Iltutmish (of the Mamluk or 'Slave' dynasty) who laid the foundation of the Sultanate's monetary system by introducing two standard coins: the Tanka (silver) and the Jital (copper). This was a significant step in centralizing authority, as the Sultan was the absolute head responsible for 'collecting fees and taxes' and maintaining the army Exploring Society: India and Beyond, Reshaping India’s Political Map, p.53.

Unlike our modern currency, which is issued by the Reserve Bank of India and has no intrinsic value of its own Understanding Economic Development, MONEY AND CREDIT, p.39, these medieval coins were valued based on the precious metal they contained. The Tanka was a high-value silver coin, while the Jital served as the 'small change' for everyday transactions. This bimetallic system (using two metals) allowed the Sultanate to facilitate both large-scale international trade and local market exchanges.

Feature	The Tanka	The Jital
Metal	Silver	Copper (or Billon, a mix of copper/silver)
Primary User	Wholesale merchants, State (taxes/salaries)	Common people, local retail markets
Introduced By	Iltutmish	Iltutmish (standardized version)

The most famous, though disastrous, evolution of this system occurred under Muhammad bin Tughlaq (1329–1330 CE). He attempted to introduce token currency, issuing copper and brass coins and decreeing they had the same legal value as silver Tankas. While a visionary idea—similar to how our modern paper notes represent value without being made of gold—it failed because the state could not maintain a monopoly over minting. Households began minting their own fake coins, flooding the market and leading to a collapse in trade. Eventually, the Sultan had to withdraw the coins, exchanging the 'fake' copper for genuine gold and silver from his treasury to restore trust.

3. Alauddin Khalji’s Economic Model: Market Control (intermediate)

To understand Alauddin Khalji’s Market Reforms, we must first understand the fundamental problem he faced: fiscal sustainability. Alauddin maintained a massive standing army to defend against Mongol invasions, but his treasury could not afford to pay them high salaries. Rather than increasing the soldiers' pay, he decided to artificially lower the cost of living. This is a classic historical example of government intervention to regulate the prices of goods when they are perceived to be too high for a specific policy goal, much like modern price ceilings Microeconomics (NCERT class XII 2025 ed.), Market Equilibrium, p.84.

Alauddin’s model was built on three pillars: Price Fixation, Supply Management, and Strict Enforcement. He did not just fix prices for luxury items; he regulated everything from food grains and cloth to horses and slaves. To ensure that these prices stayed low, he moved away from a free-market equilibrium—where price is determined by the intersection of supply and demand curves Microeconomics (NCERT class XII 2025 ed.), Market Equilibrium, p.73—and instead treated essential commodities as controlled items, similar to how modern states might manage scarce resources like foreign exchange Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking- Part I, p.67.

To implement this, he established specialized markets and a rigorous administrative hierarchy:

• Mandi: The grain market, where prices were kept strictly low.
• Sarai-i-Adl: A specialized market for manufactured goods like cloth, sugar, and dry fruits.
• State Granaries: To prevent shortages (which would drive prices up), the state collected tax in kind and stored grain in government warehouses, releasing it only during periods of scarcity.
• Market Intelligence: He employed Munhiyans (secret spies) and Barids (intelligence officers) to report on market activities directly to him, ensuring no merchant overcharged.

While the system was incredibly effective during his reign, it relied heavily on coercion. Merchants were forced to register with the state, and farmers were compelled to sell their surplus grain at fixed prices near their fields, leaving them with very little profit. This interventionist approach effectively decoupled the price of goods from the actual cost of production or market demand.

4. Administrative Shifts: The Capital Relocation (intermediate)

In the 14th century, the Delhi Sultanate faced a massive administrative challenge: how to govern a territory that now stretched from the Himalayas to the deep South. **Muhammad bin Tughlaq** recognized that ruling the Deccan and South India from the northern city of Delhi was geographically impractical. Consequently, he decided to shift his capital to **Devagiri** in Maharashtra, renaming it **Daulatabad** History, class XI (Tamilnadu state board 2024 ed.), Advent of Arabs and Turks, p.145. This wasn't merely a move of the royal court; the Sultan ordered a mass migration of the administrative elite, including important officers and influential **Sufi saints**, to ensure the new capital had the social and political infrastructure to lead the empire. Strategically, Daulatabad was chosen for its **central location** and its formidable defense—a strong fort atop a steep rocky hill. This location was intended to command the vast territories of the four major southern kingdoms that the Sultanate was absorbing: the **Yadavas** of Devagiri, the **Hoysalas** of Karnataka, the **Kakatiyas** of Warangal, and the **Pandyas** of Madurai History, class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.175. While the move aimed to integrate the economy and administration of the North and South, the execution was rigid. People were forced to travel over **1,000 km**, resulting in significant loss of life and hardship Exploring Society: India and Beyond, Class VIII NCERT (Revised ed 2025), Reshaping India’s Political Map, p.27.

Feature	Delhi	Daulatabad (Devagiri)
Strategic Focus	Defense against Mongol invasions from the Northwest.	Centralized control over the newly conquered Deccan/South.
Economic Impact	Stagnation during the migration period.	Emergence as a global city in the 14th century History, class XI (Tamilnadu state board 2024 ed.), Advent of Arabs and Turks, p.149.
Administrative Outcome	Retained as the ultimate power center.	Abandoned after a few years; led to rebellions in the South.

Ultimately, the experiment misfired. Just as it was difficult to rule the South from Delhi, the Sultan found it impossible to protect the North from the South. When he eventually returned the capital to Delhi, the vacuum of power in the Deccan allowed local subordinates to declare independence. For instance, **Madurai** became an independent Sultanate as early as **1333 CE**, signaling the beginning of the fragmentation of the Tughlaq Empire History, class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.175.

5. Agrarian Innovations: Diwan-i-Amir-Kohi (intermediate)

Muhammad bin Tughlaq, often remembered for his ambitious but ill-fated projects, was actually a visionary when it came to state-led economic development. Recognizing that the stability of the Sultanate depended on a healthy agricultural surplus, he established a specialized Department of Agriculture known as the Diwan-i-Amir-Kohi History, class XI (Tamilnadu state board 2024 ed.), Chapter 10, p. 145. This was a pioneering move in medieval India, shifting the state's role from a mere tax collector to an active participant in agrarian expansion and productivity.

The core objective of this department was to bring uncultivated land under the plow. To achieve this, the Sultanate was divided into development blocks, each headed by an official called the Amir-i-Kohi. The government provided direct financial assistance to peasants in the form of agricultural loans known as Sondhar. These loans were intended for purchasing seeds, buying oxen, and digging wells. Furthermore, the Sultan encouraged a sophisticated system of crop rotation, urging farmers to switch from lower-value crops like barley to high-value commercial crops like wheat and sugarcane to increase revenue Satish Chandra, History of Medieval India, Chapter 9, p. 104.

Despite the brilliance of the plan, the experiment was a practical failure. Several factors contributed to its collapse:

• Poor Land Selection: The land chosen for the project was often barren or of such poor quality that even with investment, it could not produce the expected yields.
• Corruption: The Amirs and other officials frequently embezzled the Sondhar loans, and the funds rarely reached the actual tillers in full.
• Time Constraints: The Sultan expected results within three years, which was an unrealistic timeframe for turning fallow land into highly productive fields.

Feature	Traditional System	Diwan-i-Amir-Kohi
State Role	Passive (Revenue collection)	Active (Investment and Planning)
Credit	Private moneylenders	State-provided loans (Sondhar)
Crop Choice	Subsistence-based	Encouraged high-value rotation

6. Rationale for Token Currency (1329–1330 CE) (exam-level)

In 1329–1330 CE, Sultan Muhammad bin Tughlaq launched one of the most ambitious and misunderstood economic experiments in medieval history: the introduction of token currency. To understand this, we must first look at the principle of intrinsic value versus face value. At the time, currency was usually made of precious metals like gold and silver, where the coin's worth was equal to the weight of the metal it contained. Tughlaq’s 'token' system, however, issued coins made of cheaper metals like copper and brass and declared by royal decree that they would have the same legal value as the silver tanka (History, class XI (Tamilnadu state board 2024 ed.), Chapter 10, p.145).

The rationale behind this move was twofold. First, there was a global shortage of silver during the 14th century, making it difficult to maintain a vast supply of precious metal coins for a growing empire. Second, Tughlaq was inspired by successful precedents in China (under Kublai Khan) and Persia, where paper and token currencies had been used effectively. It was a progressive idea—conceptually similar to the modern paper notes or digital 'e-rupees' we use today, which have little material value but are backed by the state's authority (Exploring Society: India and Beyond, Class VIII NCERT, p.27).

Feature	Standard Currency (Tanka)	Token Currency (1329 CE)
Metal	Silver / Gold	Copper / Brass / Bronze
Intrinsic Value	High (Value of the metal itself)	Low (Value of the cheap metal)
Face Value	Equal to metal weight	Equal to Silver Tanka (by law)

Despite its brilliance on paper, the experiment failed catastrophically in practice. The Sultanate lacked a monopoly over minting. The design of the new coins was so simple that they could be easily forged. Contemporary chronicler Ziauddin Barani famously remarked that "the house of every Hindu was turned into a mint." As counterfeit coins flooded the market, the currency was devalued, trade came to a standstill, and foreign merchants refused to accept the token coins. Realizing the disaster, Tughlaq eventually withdrew the order and—in a final blow to the economy—offered to exchange the fake copper coins for genuine gold and silver from the royal treasury, leaving a literal mountain of bronze discarded outside the Tughlaqabad fort (History, class XI (Tamilnadu state board 2024 ed.), Chapter 10, p.145).

7. The Forgery Crisis and Economic Collapse (exam-level)

In the history of the Delhi Sultanate, the most ambitious yet disastrous fiscal experiment was Muhammad bin Tughlaq’s introduction of token currency (1329–1330 CE). Conceptually, the Sultan was ahead of his time; he attempted to transition from commodity money (where the coin's value is in the metal itself) to representative money. He issued copper and brass coins, declaring them to have the same legal value as the silver Tanka. However, for a currency to function, it requires public confidence and a stable purchasing power Macroeconomics (NCERT class XII 2025 ed.), Open Economy Macroeconomics, p.86. Without these, even a royal decree cannot sustain its value.

The experiment collapsed into a forgery crisis because the state failed to establish a monopoly over minting. Historically, powerful rulers maintained strict control over the issuance of coinage to facilitate trade Exploring Society: India and Beyond, Social Science-Class VII, From Barter to Money, p.238. Tughlaq’s coins, however, were of such simple design that they lacked any unique royal insignia or complex engravings that were difficult to replicate. As a result, "every house of a Hindu became a mint," according to the chronicler Barani. Private individuals began producing counterfeit coins in massive quantities to pay their taxes and purchase goods, effectively turning the official currency into an unstable soft currency that fluctuated and depreciated rapidly Indian Economy, Nitin Singhania (ed 2nd), India’s Foreign Exchange and Foreign Trade, p.501.

This massive influx of forged currency led to a breakdown of trade. Foreign merchants refused to accept the "worthless" copper tokens for their goods, demanding gold or silver instead. Domestically, the market was flooded with fake coins, leading to hyper-inflation and the disappearance of genuine gold and silver coins from circulation. Realizing the disaster, the Sultan eventually withdrew the experiment. In a move that nearly emptied the royal treasury, he offered to exchange all token coins — including the heaps of forgeries — for genuine gold and silver coins from the state reserve to maintain the state's honor.

8. Solving the Original PYQ (exam-level)

To solve this question, you must connect the dots between Muhammad bin Tughlaq’s visionary administrative reforms and the practical socio-economic realities of the 14th century. Having studied the Sultanate’s economic policies, you know that the introduction of token currency (copper and brass coins) was an attempt to replace high-value silver tankas with base metals of equal legal tender. The building blocks here are the concept of fiat money and the state's role in regulating its supply. The experiment failed not because the idea was inherently flawed—modern economies use this very principle—but because the Sultanate lacked the institutional mechanism to control the production of money.

When reasoning through the options, ask yourself: What was the immediate systemic breakdown? While foreign trade was affected, it was a symptom, not the root cause. The fundamental issue was that the state did not establish a monopoly over the mints. Because the design of the new coins was too simple and lacked sophisticated security features, every house effectively became a mint. This led directly to (C) large-scale minting of spurious coins, which is the correct answer. This influx of fake currency caused massive inflation and a loss of public confidence, forcing the Sultan to eventually withdraw the scheme and pay out gold and silver to recover the copper tokens as noted in History, class XI (Tamilnadu state board 2024 ed.).

UPSC often uses 'plausible symptoms' as traps to distract you from 'root causes.' For instance, (A) rejection by foreign merchants did happen, but only as a consequence of the currency's lost value. Option (B) is factually incorrect as copper was abundant, and (D) poor quality is a distractor; the coins weren't just 'low quality' in appearance, they were unauthenticated. As a civil servant, you must distinguish between a policy's objective and the regulatory failure that leads to its collapse, which is exactly what this question tests.
