In 1724, the currency situation in Portuguese India, centered on Goa, was a complex tapestry of official Portuguese issues, pervasive foreign coinage, and chronic scarcity. The official currency was the Portuguese
xerafim, but it struggled to dominate a marketplace deeply integrated into Indian Ocean trade networks. Consequently, the most commonly circulating and trusted coins were foreign: the gold
mohur and silver
rupee of the Mughal Empire, along with a multitude of other coins from neighboring Indian states and former regional powers like the Vijayanagara Empire. This reliance on external currency severely limited Lisbon's economic control and siphoned seigniorage revenue away from the colonial administration.
The Portuguese state attempted to manage this system through the
Casa da Moeda (mint) in Goa, which primarily struck silver
tangas (a fractional coin) and copper
bazarucos. However, these local issues were often of inferior alloy and weight, leading to widespread distrust and discounting in commerce. The real pillar of high-value trade was the gold
mohur, which served as the de facto standard for major transactions and treasury accounts. A fixed, but often artificial, official exchange rate between the
xerafim and the
mohur was decreed, but market rates fluctuated based on the intrinsic silver content of Portuguese coins versus the perceived purity and weight of foreign specie.
This monetary environment created significant challenges for the
Estado da Índia. The constant outflow of silver to pay for trade goods within Asia, combined with the inability to control the money supply, led to frequent liquidity crises and hampered governmental finances. Furthermore, the coexistence of multiple coinages facilitated fraud and complicated tax collection. Thus, in 1724, the currency situation was not one of sovereign stability but of pragmatic adaptation, where Portuguese authority was forced to operate within a vibrant and autonomous regional bullion market that it could neither replace nor fully regulate.
