The currency system of the Delhi Sultanate marked a significant transition in medieval Indian economic history, moving from regional, non-standardized coins to a sophisticated, centralized monetary structure. This evolution was critical for facilitating large-scale trade, army salaries, and efficient tax collection.
Iltutmish and the Standardization of Currency
Iltutmish is credited with establishing the foundation of the Sultanate’s monetary system by introducing the silver Tanka and the copper Jital. This reform moved the economy away from the debased bull-and-horseman coins that were prevalent in pre-Sultanate times.
- The silver Tanka weighed approximately 175 grains and became the standard currency for major transactions.
- The copper Jital acted as the lower denomination currency, used for daily market transactions.
- This dual-currency system established a fixed exchange rate between silver and copper, which brought much-needed stability to urban markets.
- These coins facilitated the transition toward a cash-based economy, replacing traditional barter systems in urban administrative centers.
The Role of Currency in Military and Market Administration
Under rulers like Alauddin Khalji, the currency system was intrinsically linked to price control policies. While Khalji did not reform the weight of the Tanka, he enforced its value through strict market regulations to ensure the purchasing power of the soldiers’ salaries remained constant.
- Market officials (Shahna-i-Mandi) ensured that grain prices remained low and stable, directly tied to the fixed value of the Tanka and Jital.
- By preventing inflation, the Sultan ensured that a fixed monthly salary could sustain a soldier and his horse, thereby reducing the state’s financial burden.
- The use of currency was mandatory for tax payments, forcing peasants to sell their surplus produce in the markets, which in turn increased market circulation and urbanization.
The Token Currency Experiment of Muhammad bin Tughlaq
Muhammad bin Tughlaq is notorious in numismatic history for his failed attempt to introduce a token currency. Driven by a shortage of silver and his ambitious expansionist projects, he experimented with replacing precious metal coins with brass and copper tokens.
- Design Flaws: The design of the tokens was simple and lacked the sophisticated minting technology required to prevent counterfeiting.
- Public Response: Households across the kingdom began minting their own brass and copper coins, leading to mass inflation and the total collapse of the monetary system’s credibility.
- Withdrawal: The Sultan was forced to redeem the token coins with gold and silver from the state treasury, which severely depleted the empire’s wealth and damaged his reputation.
- Historical Impact: This event serves as a primary example of why intrinsic value was considered essential for currency in the medieval period, as state-backed fiduciary value was not yet understood by the general populace.
Structure of Sultanate Coinage
| Coin Name | Metal | Denomination/Usage |
| Tanka | Silver | Standard currency for large transactions |
| Jital | Copper | Fractional currency for daily trade |
| Adl | Silver/Billon | Smaller denomination introduced by some Sultans |
| Sasagani | Silver | Introduced by Muhammad bin Tughlaq (value of 6 Jitals) |
Key Features of Monetary Administration
- Minting Authority: The right to mint coins was an exclusive royal prerogative. Every coin bore the name of the reigning Sultan and often the name of the Caliph as a symbol of legitimacy.
- Billon Coinage: During periods of economic stress, many Sultans increased the alloy content in their coins (Billon), mixing silver with copper. This was a form of debasement used to manage treasury shortfalls.
- Regional Variations: While the Tanka was the standard, provincial governors in distant regions like Bengal often minted their own versions of the Tanka, sometimes leading to variations in weight and purity.
- Urban Integration: The circulation of currency was primarily restricted to urban centers and military camps. The rural economy continued to rely on barter and crop-sharing for a significant portion of the period.
Trivia for Prelims
- Iltutmish is considered the Father of the Monetary System of the Delhi Sultanate.
- The ratio of Jital to Tanka varied over time but was typically fixed at 48:1 or 50:1.
- Muhammad bin Tughlaq is often referred to as the Prince of Moneyers due to his extensive experiments with coin design and purity.
- The introduction of the silver Tanka by Iltutmish effectively ended the circulation of the old Gahadavala and Chahamana coinage in North India.
